CLOSE(7)                         SQL Commands                         CLOSE(7)



NAME
       CLOSE - close a cursor


SYNOPSIS
       CLOSE { name | ALL }


DESCRIPTION
       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 COMMIT or  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 CLOSE is executed, or  the
       client disconnects.

PARAMETERS
       name   The name of an open cursor to close.

       ALL    Close all open cursors.

NOTES
       PostgreSQL  does  not  have an explicit OPEN cursor statement; a cursor is considered open when it is declared.
       Use the DECLARE [declare(7)] statement to declare a cursor.

       You can see all available cursors by querying the pg_cursors system view.

       If a cursor is closed after a savepoint which is later rolled back, the CLOSE is not rolled back; that is,  the
       cursor remains closed.

EXAMPLES
       Close the cursor liahona:

       CLOSE liahona;


COMPATIBILITY
       CLOSE is fully conforming with the SQL standard. CLOSE ALL is a PostgreSQL extension.
