The CREATE TABLE statement creates a new table. The table is identified by a new_table_name, which consists of an optional qualifier, an optional owner and the name. If the qualifier is not supplied then it defaults to the current qualifier, and likewise if the table owner is not specified then this will default to the login name of the user issuing the statement.

Following the new_table_name is a list of table elements that are either column definitions or table constraints. A column must have a unique name within the table and possible super tables. The only necessary attribute of a column is a data type.

The UNDER q_table_name constraint specifies an optional supertable. The table being created will inherit all columns, indices, constraints from the supertable, specifically including the primary key. Hence the under and primary key constraints cannot be specified together. If the table being created will be owned by a non-dba user, the supertable must be owned by the same user.

The AS query_exp opt_with_data causes the table to be created based on the compile time types of columns of the SELECT expression query_exp. If WITH DATA is specified then the resultset returned by the query_exp is fed into the new table. Otherwise (if WITHOUT DATA or not specified) only the table is created.
