Before a cursor can be used to retrieve rows, it must first be opened. This is accomplished with the OPEN statement.

OPEN name;

name is the identifier of a cursor that has been previously declared in the declaration topic of the SPL program. The OPEN statement must not be executed on a cursor that has already been and still is open.

The following code 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;
