INSERT cursors

Informix^® supports insert cursors. An "insert cursor" is a special BDL cursor declared with an INSERT statement instead of a SELECT statement.

When this type 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.

Netezza^® does not support insert cursors.

Solution

Insert cursors are emulated by the Netezza database interface.
