Mapping the Cursor Attributes1 Information Types
When an ODBC 3.x application calls SQLGetInfo in an ODBC 2*.x* driver with the SQL_XXXX_CURSOR_ATTRIBUTES1 information type (for dynamic, forward-only, keyset-driver, or static cursors), the setting of the bits returned by Driver Manager depends on what the ODBC 2.x driver returns for the corresponding ODBC 2.x information types. The bits are set as shown in the following table.
Bit in SQL_XXXX_CURSOR_ATTRIBUTES1 |
Cursor type | ODBC 2.x information type |
---|---|---|
SQL_CA1_NEXT | All | SQL_FETCH_DIRECTION |
SQL_CA1_ABSOLUTE SQL_CA1_RELATIVE SQL_CA1_BOOKMARK | Dynamic, keyset-driver, static | SQL_FETCH_DIRECTION |
SQL_CA1_LOCK_NO_CHANGE SQL_CA1_LOCK_UNLOCK SQL_CA1_LOCK_EXCLUSIVE | Dynamic, keyset-driver, static | SQL_LOCK_TYPES |
SQL_CA1_POSITIONED_UPDATE SQL_CA1_POSITIONED_DELETE SQL_CA1_SELECT_FOR_UPDATE | All | SQL_POSITIONED_STATEMENTS |
SQL_CA1_POS_POSITION SQL_CA1_POS_DELETE SQL_CA1_POS_REFRESH SQL_CA1_POS_BULK_ADD | Dynamic, keyset-driver, static | SQL_POS_OPERATIONS |
