The following is an example of Oracle stored procedure, in which table type collection is used to process the data.
Process Data Using Table Type in Oracle Stored Procedure Example
Create the following tables and insert the data to test in your schema.
CREATE TABLE EMP ( EMPNO NUMBER(4), ENAME VARCHAR2(10 BYTE), JOB VARCHAR2(9 BYTE), MGR NUMBER(4), HIREDATE DATE, SAL NUMBER(7,2), COMM NUMBER(7,2), DEPTNO NUMBER(2) ) /
CREATE TABLE EMP_BONUS ( EMPNO NUMBER(4), BONUS_AMOUNT NUMBER ) /
SET DEFINE OFF; Insert into EMP (EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, DEPTNO) Values (7369, 'SMITH', 'CLERK', 7902, TO_DATE('12/17/1980 00:00:00', 'MM/DD/YYYY HH24:MI:SS'), 800, 20); Insert into EMP (EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO) Values (7499, 'ALLEN', 'SALESMAN', 7698, TO_DATE('02/20/1981 00:00:00', 'MM/DD/YYYY HH24:MI:SS'), 1600, 300, 30); Insert into EMP (EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO) Values (7521, 'WARD', 'SALESMAN', 7698, TO_DATE('02/22/1981 00:00:00', 'MM/DD/YYYY HH24:MI:SS'), 1250, 500, 30); COMMIT;
Create Stored Procedure
CREATE OR REPLACE PROCEDURE process_bonus IS CURSOR c_emp IS SELECT EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO FROM emp; /* declare table type in the procedure declare section as below */ TYPE t_emp_table IS TABLE OF emp%ROWTYPE INDEX BY BINARY_INTEGER; t_emp t_emp_table; BEGIN OPEN c_emp; /* fetch cursor data into table type using bulk collect */ FETCH c_emp BULK COLLECT INTO t_emp; CLOSE c_emp; FOR i IN t_emp.FIRST .. t_emp.LAST LOOP /* insert 5% bonus of employee's salary into emp_bonus table */ INSERT INTO emp_bonus (empno, bonus_amount) VALUES (t_emp (i).empno, t_emp (i).sal * 5 / 100); END LOOP; COMMIT; END;
Test Using PL/SQL Block
BEGIN process_bonus; END;
Check The Bonus Table for Processed Data
SELECT * FROM EMP_BONUS;
Output:
EMPNO | BONUS_AMOUNT |
7369 | 40 |
7499 | 80 |
7521 | 62.5 |
