Declaring a cursor v16

Before you can use a cursor, you must first declare it in the declaration section of the SPL program. A cursor declaration appears as follows:

CURSOR <name> IS <query>;

Where:

• name is an identifier used to reference the cursor and its result set later in the program.
• query is a SQL SELECT command that determines the result set retrievable by the cursor.

This example shows some cursor declarations:

CREATE OR REPLACE PROCEDURE cursor_example
IS
    CURSOR emp_cur_1 IS SELECT * FROM emp;
    CURSOR emp_cur_2 IS SELECT empno, ename FROM emp;
    CURSOR emp_cur_3 IS SELECT empno, ename FROM emp WHERE deptno = 10
        ORDER BY empno;
BEGIN
    ...
END;
