SQL99 Syntax and Description

CLOSE { cursor_name }

The cursor_name is the name of the cursor created with the DECLARE CURSOR command.

Example

This example from Microsoft SQL Server opens a cursor and fetches all the rows:

DECLARE employee_cursor CURSOR FOR
  SELECT lname, fname
  FROM pubs.dbo.authors
  WHERE lname LIKE 'K%'

OPEN employee_cursor

FETCH NEXT FROM employee_cursor

WHILE @@FETCH_STATUS = 0
BEGIN
  FETCH NEXT FROM Employee_Cursor
END

CLOSE employee_cursor

DEALLOCATE employee_cursor

Warning

The DEALLOCATE statement in Microsoft SQL Server releases the resources and data structures used by the cursor, but Oracle, PostgreSQL, and MySQL do not use it.
