プロシージャを使用してテーブルの列を更新する

Question

CREATE TABLE employees 
(
    ENO  NUMBER (3), 
    ENAME  VARCHAR2 (35), 
    HIREDATE DATE, 
    SAL  NUMBER (6), 
    EXPR  NUMBER (3), 
    DEPTNO  NUMBER (3), 
    JOB  VARCHAR2 (20), 
    COMM  NUMBER (10) 
) 

これは私のテーブル構造です。「COMM」列には値がありません。「SAL」列に基づいて値を追加したい私たちはあなたの宿題を書くべき手順、値

Answer 1

CREATE OR REPLACE PACKAGE XX_UPDATETBEMP 
AS 
    PROCEDURE XX_UPDATECOMM; 
END XX_UPDATETBEMP; 



CREATE or REPLACE PACKAGE BODY XX_UPDATETBEMP 

IS 
    PROCEDURE XX_UPDATECOMM 
    IS 
    BEGIN 
     UPDATE emp 
     SET comm = 
       CASE 
        WHEN sal BETWEEN 30000 AND 50000 THEN .20 * sal 
        WHEN sal BETWEEN 50000 AND 70000 THEN .15 * sal 
     WHEN sal BETWEEN 70000 AND 100000 THEN .10 * sal 
       END; 
    END XX_UPDATECOMM; 
END XX_UPDATETBEMP; 

Answer 2

PROCEDURE XX_UDCOMMS IS 
    CURSOR C_TBEMP IS 
     SELECT * FROM XX_TBEMP; 
    l_comm NUMBER; 
    BEGIN 
    FOR C IN C_TBEMP LOOP 
     l_comm := NULL; 

     IF C.SAL BETWEEN 30000 AND 49999 THEN 
     l_comm := c.sal * 0.2; 
     ELSIF C.SAL BETWEEN 50000 AND 79999 THEN 
     l_comm := c.sal * 0.15; 
     ELSIF C.SAL BETWEEN 80000 AND 99999 THEN 
     l_comm := c.sal * 0.1; 
     END IF; 

     UPDATE XX_TBEMP SET COMM = l_comm WHERE c.eno = eno; 
    END LOOP; 
    end;
