if a database-access error occurs. |
In general, parameter values remain in force for repeated use of a RowSet. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling clearParameters.
Method getCommand()
Synopsis:
public String getCommand();
Get the rowset's command property. The command property contains a command string that can be executed to fill the rowset with data. The default value is null.
Method getConcurrency()
Synopsis:
public int getConcurrency() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
Get the rowset concurrency.
Method getDataSourceName()
Synopsis:

public void setMaxRows(int max) throws java.sql.SQLException;
|
Parameters |
|---|
|
|
|
Exceptions |

Parameters |
|---|
|
|
|
|
|
|
|
Exceptions |
|
|---|---|
|
SQLException |
if a database access error occurs |
Sets the designated parameter to SQL NULL. This version of setNull should be used for user-named types and REF type parameters. Examples of user-named types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.
Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-named type the name is the type name of the parameter itself. For a REF parameter the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-named and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-named or REF type, the given typeName is ignored.
Method setObject(int, Object)
Synopsis:
public void setObject(int parameterIndex, java.lang.Object x)
throws java.sql.SQLException;
|
Parameters |
|---|
|
|
|
|
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
Set the value of a parameter using an object; use the java.lang equivalent objects for integral values.
The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument java object will be converted to the corresponding SQL type before being sent to the database.
Note that this method may be used to pass datatabase specific abstract data types, by using a Driver specific Java type. If the object is of a class implementing SQLData, the rowset should call its method writeSQL() to write it to the SQL data stream. else If the object is of a class implementing Ref, Blob, Clob, Struct, or Array then pass it to the database as a value of the corresponding SQL type. Raise an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of those interfaces.
Method setObject(int, Object, int)
Synopsis:
public void setObject(int parameterIndex, java.lang.Object x,
int targetSqlType)
throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
This method is like setObject above, but the scale used is the scale of the second parameter. Scalar values have a scale of zero. Literal values have the scale present in the literal. While it is supported, it is not recommended that this method not be called with floating point input values.
Method setObject(int, Object, int, int)
Synopsis:
public void setObject(int parameterIndex, java.lang.Object x,
int targetSqlType, int scale)
throws java.sql.SQLException;

java.sql.Types |
Set the value of a parameter using an object; use the java.lang equivalent objects for integral values.
The given Java object will be converted to the targetSqlType before being sent to the database. If the object is of a class implementing SQLData, the rowset should call its method writeSQL() to write it to the SQL data stream. else If the object is of a class implementing Ref, Blob, Clob, Struct, or Array then pass it to the database as a value of the corresponding SQL type.
Note that this method may be used to pass datatabase- specific abstract data types.

When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. JDBC will read the data from the stream as needed, until it reaches end-of-file. The JDBC driver will do any necessary conversion from UNICODE to the database char format. |
Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

SQLException |
if a database-access error occurs. |
Set the url used to create a connection. Setting this property is optional. If a url is used, a JDBC driver that accepts the url must be loaded by the application before the rowset is used to connect to a database. The rowset will use the url internally to create a database connection when reading or writing data. Either a url or a data source name is used to create a connection, whichever was specified most recently.

11.11.2.Class OPLCachedRowSet
A OPLCachedRowSet is a disconnected, serializable, scrollable container for tabular data. A primary purpose of the OPLCachedRowSet class is to provide a representation of a JDBC ResultSet that can be passed between different components of a remote application. For example, a OPLCachedRowSet can be used to send the result of a query executed by an Enterprise JavaBeans component running in a server environment over a network to a client running in a web browser. A second use for OPLCachedRowSets is to provide scrolling and updating for ResultSets that don't provide these capabilities themselves. A OPLCachedRowSet can be used to augment the capabilities of a JDBC driver that doesn't have full support for scrolling and updating. Finally, a OPLCachedRowSet can be used to provide Java applications with access to tabular data in an environment such as a thin client or PDA, where it would be inappropriate to use a JDBC driver due to resource limitations or security considerations. The OPLCachedRowSet class provides a means to "get rows in" and "get changed rows out" without the need to implement the full JDBC API.
A OPLCachedRowSet object can contain data retrieved via a JDBC driver or data from some other source, such as a spreadsheet. Both a OPLCachedRowSet object and its metadata can be created from scratch. A component that acts as a factory for rowsets can use this capability to create a rowset containing data from non-JDBC data sources.
The term 'disconnected' implies that a OPLCachedRowSet only makes use of a JDBC connection briefly while data is being read from the database and used to populate it with rows, and again while updated rows are being propagated back to the underlying database. During the remainder of its lifetime, a OPLCachedRowSet object isn't associated with an underlying database connection. A OPLCachedRowSet object can simply be thought of as a disconnected set of rows that are being cached outside of a data source. Since all data is cached in memory, OPLCachedRowSets are not appropriate for extremely large data sets.
The contents of a OPLCachedRowSet may be updated and the updates can be propagated to an underlying data source. OPLCachedRowSets support an optimistic concurrency control mechanism - no locks are maintained in the underlying database during disconnected use of the rowset. Both the original value and current value of the OPLCachedRowSet are maintained for use by the optimistic routines.

Members
Constructor OPLCachedRowSet()
Synopsis:
public OPLCachedRowSet() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Create a OPLCachedRowSet object. The object has no metadata.
Method absolute(int)
Synopsis:
public boolean absolute(int row) throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or row is 0, or rowset type is TYPE_FORWARD_ONLY. |
Move to an absolute row number in the rowset. It notifies listeners that the cursor has moved.
If row is positive, moves to an absolute row with respect to the beginning of the rowset. The first row is row 1, the second is row 2, etc.
If row is negative, moves to an absolute row position with respect to the end of rowset. For example, calling absolute(-1) positions the cursor on the last row, absolute(-2) indicates the next-to-last row, etc.
An attempt to position the cursor beyond the first/last row in the rowset, leaves the cursor before/after the first/last row, respectively.
Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().
Method acceptChanges()
Synopsis:
public void acceptChanges() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Propagate all row update, insert, and delete changes to a data source. An SQLException is thrown if any of the updates cannot be propagated. If acceptChanges() fails then the caller can assume that none of the updates are reflected in the data source. The current row is set to the first "updated" row that resulted in an exception, in the case that an exception is thrown. With one exception, if the row that caused the exception is a "deleted" row, then in the usual case, when deleted rows are not shown, the current row isn't affected. When successful, calling acceptChanges() replaces the original value of the rowset with the current value. Note: Both the original and current value of the rowset are maintained. The original state is the value of the rowset following its creation (i.e. empty), or following the last call to acceptChanges(), execute(), populate(), release(), or restoreOriginal(). Internally, a RowSetWriter component is envoked to write the data for each row.
Method acceptChanges(Connection)
Synopsis:
public void acceptChanges(java.sql.Connection _conn)
throws java.sql.SQLException;
|
Parameters |
|---|
|
|
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Like acceptChanges() above, but takes a Connection argument. The Connection is used internally when doing the updates. This form isn't used unless the underlying data source is a JDBC data source.
Method afterLast()
Synopsis:
public void afterLast() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or rowset type is TYPE_FORWARD_ONLY. |
Moves to the end of the rowset, just after the last row. Has no effect if the rowset contains no rows. It notifies listeners that the cursor has moved.
Method beforeFirst()
Synopsis:
public void beforeFirst() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or rowset type is TYPE_FORWARD_ONLY |
Moves to the front of the rowset, just before the first row. Has no effect if the rowset contains no rows. It notifies listeners that the cursor has moved.
Method cancelRowDelete()
Synopsis:
public void cancelRowDelete() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Cancels deletion of the current row and notifies listeners that a row has changed. After calling cancelRowDelete() the current row is no longer marked for deletion. An exception is thrown if there is no current row. Note: This method can be ignored if deleted rows aren't being shown (the normal case).
Method cancelRowInsert()
Synopsis:
public void cancelRowInsert() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Cancels insertion of the current row and notifies listeners that a row has changed. An exception is thrown if the row isn't an inserted row. The current row is immediately removed from the rowset. This operation cannot be undone.
Method cancelRowUpdates()
Synopsis:
public void cancelRowUpdates() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
The cancelRowUpdates() method may be called after calling an updateXXX() method(s) and before calling updateRow() to rollback the updates made to a row. If no updates have been made or updateRow() has already been called, then this method has no effect. It notifies listeners that a row has changed, if it has effect.
Method clearWarnings()
Synopsis:
public void clearWarnings() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
After this call getWarnings returns null until a new warning is reported for this ResultSet.
Method close()
Synopsis:
public void close() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Releases the current contents of this rowset, discarding outstanding updates. The rowset contains no rows after the method release is called. This method sends a RowSetChangedEvent object to all registered listeners prior to returning.
Method columnUpdated(int)
Synopsis:
public boolean columnUpdated(int columnIndex)
throws java.sql.SQLException;
|
Parameters |
|---|
|
|
|
|
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs |
Determine if the column from the current row has been updated.
Method createCopy()
Synopsis:
public RowSet createCopy() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Creates a RowSet object that is a deep copy of this OPLCachedRowSet object's data. Updates made on a copy are not visible to the original rowset; a copy of a rowset is completely independent from the original. Making a copy saves the cost of creating an identical rowset from first principles, which can be quite expensive. For example, it doesn't do the query to a remote database server.
Method createShared()
Synopsis:
public RowSet createShared() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Returns a new rowset object backed by the same data. Updates made by a shared duplicate are visible to the original rowset and other duplicates. A rowset and its duplicates form a set of cursors that iterate over a shared set of rows, providing different views of the underlying data. Duplicates also share property values. So, for example, if a rowset is read-only then all of its duplicates will be read-only.
Method deleteRow()
Synopsis:
public void deleteRow() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or if called when on the insert row. |
Delete the current row from this OPLCachedRowSet object and it notifies listeners that a row has changed. Cannot be called when the cursor is on the insert row. The method marks the current row as deleted, but it does not delete the row from the underlying data source. The method acceptChanges must be called to delete the row in the data source.
Method execute()
Synopsis:
public void execute() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Populates this OPLCachedRowSet object with data. This form of the method uses the rowset's user, password, and url or data source name properties to create a database connection. If properties that are needed have not been set, this method will throw an exception. Another form of this method uses an existing JDBC Connection object instead of creating a new one; therefore, it ignores the properties used for establishing a new connection. The query specified by the command property is executed to create a ResultSet object from which to retrieve data. The current contents of the rowset are discarded, and the rowset's metadata is also (re)set. If there are outstanding updates, they are also ignored. The method execute closes any database connections that it creates.
Method execute(Connection)
Synopsis:
public void execute(java.sql.Connection _conn)
throws java.sql.SQLException;
|
Parameters |
|---|
|
|
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Populates the rowset with data. The first form uses the properties: url/data source name, user, and password to create a database connection. If these properties haven't been set, an exception is thrown. The second form uses an existing JDBC connection object instead. The values of the url/data source name, user, and password properties are ignored when the second form is used. Execute() closes any database connections that it creates. The command specified by the command property is executed to retrieve the data. The current contents of the rowset are discarded and the rowset's metadata is also (re)set. If there are outstanding updates, they are also ignored.
Method findColumn(String)

Method insertRow()
Synopsis:
public void insertRow() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database access error occurs, if this method is called when the cursor is not on the insert row |
Inserts the contents of the insert row into this rowset following the current row and it notifies listeners that the row has changed. The cursor must be on the insert row when this method is called. The method marks the current row as inserted, but it does not insert the row to the underlying data source. The method acceptChanges must be called to insert the row to the data source.
Method isAfterLast()
Synopsis:
public boolean isAfterLast() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |

public boolean isFirst() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
Determine if the cursor is on the first row of the rowset.
Method isLast()
Synopsis:
public boolean isLast() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
Determine if the cursor is on the last row of the rowset. Note: Calling isLast() may be expensive since the rowset might need to check ahead one row in order to determine whether the current row is the last row in the rowset.
Method last()
Synopsis:
public boolean last() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or rowset type is TYPE_FORWARD_ONLY. |
Moves to the last row in the rowset. It notifies listeners that the cursor has moved.
Method moveToCurrentRow()
Synopsis:
public void moveToCurrentRow() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or the rowset is not updatable |
Move the cursor to the remembered cursor position, usually the current row. Has no effect unless the cursor is on the insert row.
Method moveToInsertRow()
Synopsis:
public void moveToInsertRow() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or the rowset is not updatable |
Move to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable rowset. It is essentially a buffer where a new row may be constructed by calling the updateXXX() methods prior to inserting the row into the rowset. Only the updateXXX(), getXXX(), and insertRow() methods may be called when the cursor is on the insert row. All of the columns in a rowset must be given a value each time this method is called before calling insertRow(). UpdateXXX()must be called before getXXX() on a column.
Method next()
Synopsis:
public boolean next() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
A ResultSet is initially positioned before its first row; the first call to next makes the first row the current row; the second call makes the second row the current row, etc.
If an input stream from the previous row is open, it is implicitly closed. The ResultSet's warning chain is cleared when a new row is read.
Method populate(ResultSet)
Synopsis:
public void populate(java.sql.ResultSet rs)
throws java.sql.SQLException;
|
Parameters |
|---|
|
|
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Populate the OPLCachedRowSet object with data from a ResultSet. This method is an alternative to execute() for filling the rowset with data. Populate() doesn't require that the properties needed by execute(), such as the command property, be set. A RowSetChangedEvent is sent to all registered listeners prior to returning.
Method previous()
Synopsis:
public boolean previous() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or rowset type is TYPE_FORWAR_DONLY. |
Moves to the previous row in the rowset.
Note: previous() is not the same as relative(-1) since it makes sense to call previous() when there is no current row.
Method refreshRow()
Synopsis:
public void refreshRow() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or if called when on the insert row. |
Sets the current row with its original value and marks the row as not updated, thus undoing any changes made to the row since the last call to the methods updateRow or deleteRow. This method should be called only when the cursor is on a row in this rowset. Cannot be called when on the insert row.
Method relative(int)
Synopsis:
public boolean relative(int rows) throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or there is no current row, or rowset type is TYPE_FORWARD_ONLY. |
Moves a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the rowset positions the cursor before/after the the first/last row. Calling relative(0) is valid, but does not change the cursor position. It notifies listeners that the cursor has moved.
Note: Calling relative(1) is different than calling next() since is makes sense to call next() when there is no current row, for example, when the cursor is positioned before the first row or after the last row of the rowset.
Method release()
Synopsis:
public void release() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Releases the current contents of the rowset. Outstanding updates are discarded. The rowset contains no rows after release is called. A RowSetChangedEvent is sent to all registered listeners prior to returning.
Method restoreOriginal()
Synopsis:
public void restoreOriginal() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
Restores the rowset to its original state ( the original value of the rowset becomes the current value). All updates, inserts, and deletes made to the original state are lost. The cursor is positioned before the first row. A RowSetChangedEvent is sent to all registered listeners prior to returning.
Method rowDeleted()
Synopsis:
public boolean rowDeleted() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs |
|
Additional Information |

11.11.6.Class OPLJdbcRowSet
A OPLJdbcRowSet is a connected rowset. The purpose of the OPLJdbcRowSet class is to act like a JavaBean at design time and provide a thin layer that wraps around a JDBC ResultSet at runtime.
When execute() is called a OPLJdbcRowSet object opens a JDBC connection internally which remains open until close() is called, unless a Connection is passed to execute() explicitly, in which case that Connection is used instead. ResultSet operations such as cursor movement, updating, etc. are simply delegated to an underlying JDBC ResultSet object which is maintained internally.

Method absolute(int)
Synopsis:
public boolean absolute(int row) throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or row is 0, or result set type is TYPE_FORWARD_ONLY. |
Move to an absolute row number in the result set.
If row is positive, moves to an absolute row with respect to the beginning of the result set. The first row is row 1, the second is row 2, etc.
If row is negative, moves to an absolute row position with respect to the end of result set. For example, calling absolute(-1) positions the cursor on the last row, absolute(-2) indicates the next-to-last row, etc.
An attempt to position the cursor beyond the first/last row in the result set, leaves the cursor before/after the first/last row, respectively.
Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().
Method afterLast()
Synopsis:
public void afterLast() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or result set type is TYPE_FORWARD_ONLY. |
Moves to the end of the result set, just after the last row. Has no effect if the result set contains no rows.
Method beforeFirst()
Synopsis:
public void beforeFirst() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or result set type is TYPE_FORWARD_ONLY |
Moves to the front of the result set, just before the first row. Has no effect if the result set contains no rows.
Method cancelRowUpdates()
Synopsis:
public void cancelRowUpdates() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if an error occurs. |
The cancelRowUpdates() method may be called after calling an updateXXX() method(s) and before calling updateRow() to rollback the updates made to a row. If no updates have been made or updateRow() has already been called, then this method has no effect.
Method clearWarnings()
Synopsis:
public void clearWarnings() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
After this call getWarnings returns null until a new warning is reported for this ResultSet.
Method close()
Synopsis:
public void close() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
In some cases, it is desirable to immediately release a ResultSet's database and JDBC resources instead of waiting for this to happen when it is automatically closed; the close method provides this immediate release.
Note: A ResultSet is automatically closed by the Statement that generated it when that Statement is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results. A ResultSet is also automatically closed when it is garbage collected.
Method deleteRow()
Synopsis:
public void deleteRow() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or if called when on the insert row. |
Delete the current row from the result set and the underlying database. Cannot be called when on the insert row.
Method execute()
Synopsis:
public void execute() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
Populates the rowset with data. Execute() may use the following properties: url, data source name, user name, password, transaction isolation, and type map to create a connection for reading data. Execute may use the following properties to create a statement to execute a command: command, read only, maximum field size, maximum rows, escape processing, and query timeout. If the required properties have not been set, an exception is thrown. If successful, the current contents of the rowset are discarded and the rowset's metadata is also (re)set. If there are outstanding updates, they are ignored.
Method execute(Connection)
Synopsis:
public void execute(java.sql.Connection _conn)
throws java.sql.SQLException;
|
Parameters |
|---|
|
|
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
Populates the rowset with data. Uses an existing JDBC connection object. The values of the url/data source name, user, and password properties are ignored. The command specified by the command property is executed to retrieve the data. The current contents of the rowset are discarded and the rowset's metadata is also (re)set. If there are outstanding updates, they are also ignored.

|
A column value can be retrieved as a stream of Unicode characters and then read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC driver will do any necessary conversion from the database format into Unicode. |
Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a get method implicitly closes the stream. . Also, a stream may return 0 for available() whether there is data available or not.

Method getWarnings()
Synopsis:
public SQLWarning getWarnings() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
The first warning reported by calls on this ResultSet is returned. Subsequent ResultSet warnings will be chained to this SQLWarning.
The warning chain is automatically cleared each time a new row is read.
Note: This warning chain only covers warnings caused by ResultSet methods. Any warning caused by statement methods (such as reading OUT parameters) will be chained on the Statement object.
Method insertRow()
Synopsis:
public void insertRow() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database access error occurs, if this method is called when the cursor is not on the insert row, or if not all of non-nullable columns in the insert row have been given a value |
Inserts the contents of the insert row into this ResultSet objaect and into the database. The
cursor must be on the insert row when this method is called.
Method isAfterLast()
Synopsis:
public boolean isAfterLast() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
Determine if the cursor is after the last row in the result set.
Method isBeforeFirst()
Synopsis:
public boolean isBeforeFirst() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
Determine if the cursor is before the first row in the result set.
Method isFirst()
Synopsis:
public boolean isFirst() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
Determine if the cursor is on the first row of the result set.
Method isLast()
Synopsis:
public boolean isLast() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
Determine if the cursor is on the last row of the result set. Note: Calling isLast() may be expensive since the JDBC driver might need to fetch ahead one row in order to determine whether the current row is the last row in the result set.
Method last()
Synopsis:
public boolean last() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or result set type is TYPE_FORWARD_ONLY. |
Moves to the last row in the result set.
Method moveToCurrentRow()
Synopsis:
public void moveToCurrentRow() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or the result set is not updatable |
Move the cursor to the remembered cursor position, usually the current row. Has no effect unless the cursor is on the insert row.
Method moveToInsertRow()
Synopsis:
public void moveToInsertRow() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or the result set is not updatable |
Move to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable result set. It is essentially a buffer where a new row may be constructed by calling the updateXXX() methods prior to inserting the row into the result set. Only the updateXXX(), getXXX(), and insertRow() methods may be called when the cursor is on the insert row. All of the columns in a result set must be given a value each time this method is called before calling insertRow(). UpdateXXX()must be called before getXXX() on a column.
Method next()
Synopsis:
public boolean next() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs. |
A ResultSet is initially positioned before its first row; the first call to next makes the first row the current row; the second call makes the second row the current row, etc.
If an input stream from the previous row is open, it is implicitly closed. The ResultSet's warning chain is cleared when a new row is read.
Method previous()
Synopsis:
public boolean previous() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or result set type is TYPE_FORWAR_DONLY. |
Moves to the previous row in the result set.
Note: previous() is not the same as relative(-1) since it makes sense to call previous() when there is no current row.
Method refreshRow()
Synopsis:
public void refreshRow() throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or if called when on the insert row. |
Refresh the value of the current row with its current value in the database. Cannot be called when on the insert row. The refreshRow() method provides a way for an application to explicitly tell the JDBC driver to refetch a row(s) from the database. An application may want to call refreshRow() when caching or prefetching is being done by the JDBC driver to fetch the latest value of a row from the database. The JDBC driver may actually refresh multiple rows at once if the fetch size is greater than one. All values are refetched subject to the transaction isolation level and cursor sensitivity. If refreshRow() is called after calling updateXXX(), but before calling updateRow() then the updates made to the row are lost. Calling refreshRow() frequently will likely slow performance.
Method relative(int)
Synopsis:
public boolean relative(int rows) throws java.sql.SQLException;
|
Exceptions |
|
|---|---|
|
SQLException |
if a database-access error occurs, or there is no current row, or result set type is TYPE_FORWARD_ONLY. |
Moves a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the the first/last row. Calling relative(0) is valid, but does not change the cursor position.
Note: Calling relative(1) is different than calling next() since is makes sense to call next() when there is no current row, for example, when the cursor is positioned before the first row or after the last row of the result set.
Method rowDeleted()
Synopsis:
public boolean rowDeleted() throws java.sql.SQLException;
