CLOSE cursor
The name of an open cursor to close.
Message returned if the cursor is successfully closed.
This warning is given if cursor is not declared or has already been closed.
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.
An implicit close is executed for every open cursor when a transaction is terminated by COMMIT or ROLLBACK.
Postgres does not have an explicit OPEN cursor statement; a cursor is considered open when it is declared. Use the DECLARE statement to declare a cursor.
Close the cursor liahona:
CLOSE liahona;
CLOSE is fully compatible with SQL92.
