Opening a cursor v14
Before you can use a cursor to retrieve rows, you must open it using the OPEN statement.
OPEN <name>;
name is the identifier of a cursor that was previously declared in the declaration section of the SPL program. Don't execute the OPEN statement on a cursor that is already open.
This examples shows an OPEN statement with its corresponding cursor declaration:
CREATE OR REPLACE PROCEDURE cursor_example
IS
CURSOR emp_cur_3 IS SELECT empno, ename FROM emp WHERE deptno = 10
ORDER BY empno;
BEGIN
OPEN emp_cur_3;
...
END;
