Host - the hostname of the server on which Informix is running

Port - the port on which the Informix instance listens

Database - the name of a valid database

Database Server - the name of the Informix Server running on a given Host

Username - the name of a valid Informix user

Advanced - additional optional configuration parameters:

Row Buffer Size - This attribute specifies the number of records to be transported over the network in a single network hop. Values can range from 1 to 99.

Hide Login Dialog - Suppress the ODBC "Username" and "Password" login dialog box when interacting with your ODBC DSN from within an ODBC-compliant application.

Read-only connection - Specify whether the connection is to be read-only. Make sure the checkbox is unchecked to request a read/write connection.

Drop Catalog from Meta calls - Enable this option to have the catalog name not appear for tables, views and procedures when requesting database meta-data.

Drop Schema from Meta calls - Enable this option to have the schema-name not appear for tables, views and procedures when requesting database meta-data.

SQLStatistics disabled - Check this box to have SQLStatistics() return an empty resultset. Use this if the underlying database does not support retrieving statistics about a table (e.g. what indexes there are on it).

No support of quoted identifier - If it is set, the call SQLGetInfo for 'SQL_IDENTIFIER_QUOTE_CHAR' will return the space (" "). It can be used if DBMS doesn't support quoted SQL such as select * from "account"

No support of search string escape - If it is set, the call SQLGetInfo() for 'SQL_LIKE_ESCAPE_CLAUSE' will return the space (" "). It can be used if DBMS doesn't support SQL escape patterns

Patch of NULL size of SQL_CHAR - If set this option overrides the size of SQL_CHAR column type returned by the database with the value set in the text box (in bytes). With the default value of 0 the driver uses the size returned by the database.

SQL_DBMS Name - Manually override the SQLGetInfo(SQL_DBMS_NAME) response returned by the driver. This is know to be required for products like Microsoft InfoPath for which the return the value should be "SQL Server".

Initialization SQL - Lets you specify a file containing SQL statements that will be run against the database upon connection, automatically.

Cursor Sensitivity - Enables or disables the row version cache used with dynamic cursors. When dynamic cursor sensitivity is set high, the Cursor Library calculates checksums for each row in the current rowset and compares these with the checksums (if any) already stored in the row version cache for the same rows when fetched previously. If the checksums differ for a row, the row has been updated since it was last fetched and the row status flag is set to SQL_ROW_UPDATED. The row version cache is then updated with the latest checksums for the rowset. From the user's point of view, the only visible difference between the two sensitivity settings is that a row status flag can never be set to SQL_ROW_UPDATED when the cursor sensitivity is low. (The row status is instead displayed as SQL_ROW_SUCCESS.) In all other respects, performance aside, the two settings are the same - deleted rows don't appear in the rowset, updates to the row since the row was last fetched are reflected in the row data, and inserted rows appear in the rowset if their keys fall within the span of the rowset. If your application does not need to detect the row status SQL_ROW_UPDATED, you should leave the 'High Cursor Sensitivity' checkbox unchecked, as performance is improved. The calculation and comparison of checksums for each row fetched carries an overhead. If this option is enabled, the table oplrvc must have been created beforehand using the appropriate script for the target database.

MaxRows Override - Allows you to define a limit on the maximum number of rows to returned from a query. The default value of 0 means no limit.

Disable AutoCommit - Change the default commit behaviour of the OpenLink Lite Driver. The default mode is AutoCommit mode (box unchecked).

Disable Rowset Size Limit - Disable the limitation enforced by the cursor library. The limitation is enforced by default to prevent the Driver claiming all available memory in the event that a resultset is generated from an erroneous query is very large. The limit is normally never reached.

Defer fetching of long data - Defer fetching of LONG (BINARY, BLOB etc.) data unless explicitly requested in query. This provides significant performance increase when fields in query does not include LONG data fields.

Multiple Active Statements Emulation - Enables use of Multiple Active statements in an ODBC application even if the underlying database does not allow this, as it is emulated in the driver.
