| SQL adaptation guide For PostgreSQL 8.x.y, 9.x.y / BDL programming | |
Informix® supports insert cursors. An "insert cursor" is a special BDL cursor declared with an INSERT statement instead of a SELECT statement. When this kind of cursor is open, you can use the PUT instruction to add rows and the FLUSH instruction to insert the records into the database.
For Informix database with transactions, OPEN, PUT and FLUSH instructions must be executed within a transaction.
PostgreSQL does not support insert cursors.
Insert cursors are emulated by the PostgreSQL database interface.
