Synopsis
CLOSE cursor
Inputs
- cursor
The name of an open cursor to close.

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.
An implicit close is executed for every open cursor when a
transaction is terminated by COMMIT
or ROLLBACK.
Notes
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.
Usage
Close the cursor liahona:
CLOSE liahona;
Compatibility
SQL92
CLOSE is fully compatible with SQL92.
