CLOSE -- close a cursor
CLOSE frees the resources associated with an open cursor.
After the cursor is closed, no subsequent operations
are allowed on it. A cursor should be closed when it is
no longer needed.
Every non-holdable open cursor is implicitly closed when a
transaction is terminated by
ROLLBACK. A holdable cursor is implicitly
closed if the transaction that created it aborts via
ROLLBACK. If the creating transaction successfully
commits, the holdable
cursor remains open until an explicit
executed, or the client disconnects.
- The name of an open cursor to close.
PostgreSQL does not have an explicit
OPEN cursor statement; a cursor is considered
open when it is declared. Use the
statement to declare a cursor.
You can see all available cursors by querying the
pg_cursors system view.
Close the cursor
CLOSE is fully conforming with the SQL standard.
