Description

DBMS CLOSE CURSOR closes an open cursor. Closing a cursor frees all structures associated with the cursor.

Closing a cursor turns off all attributes assigned to the cursor with the DBMS commands: ALIAS, CATQUERY, COLUMN_NAMES, FORMAT, OCCUR, START, STORE FILE, TYPE, and UNIQUE.

To close the default SELECT cursor on the default connection, specify:

DBMS CLOSE CURSOR

To close the default SELECT cursor on a specific connection, specify:

DBMS WITH CONNECTION connection CLOSE CURSOR

Panther will automatically declare another default SELECT cursor if needed.

To close a named cursor, specify either of the following:

DBMS CLOSE CURSOR cursor
DBMS WITH CURSOR cursor CLOSE CURSOR

Closing a connection also closes all cursors associated with the connection.

Example

// Assign a catquery and aliases to the default SELECT
// cursor. Close the cursor when finished.
DBMS CATQUERY TO FILE titlelist
DBMS ALIAS title_id "Title ID", name "Title",\
film_minutes "Length", pricecat "Price Category"
DBMS QUERY SELECT title_id, name, film_minutes, pricecat \
FROM titles
