forループを使ってplsqlのプロシージャで私のテーブルの列を更新する方法は？

Question

iはforループせずにコードを書かれていたが、あなたのテーブル構造を提供することができ

begin 
    UPDATE XX_TBEMP 
    SET COMM=SAL*.05 
    WHERE SAL BETWEEN 80000 AND 99999; 
end PR_UPDATETBEMP; 

Answer 1

create or replace PACKAGE XX_UPDATETBEMP AS 
PROCEDURE XX_UPDATECOMM; 
end XX_UPDATETBEMP; 

create or replace PACKAGEBODY XX_UPDATETBEMP AS 
PROCEDURE XX_UPDATECOMM IS 
CURSOR C_TBEMP IS SELECT * FROM XX_TBEMP; 
R_TBEMP C_TBEMP%ROWTYPE; 
BEGIN 

FOR SAL IN C_TBEMP 
LOOP 
UPDATE XX_TBEMP 
     SET COMM  = sal * 0.2 where SAL BETWEEN 30000 AND 49999; 
     UPDATE XX_TBEMP 
     SET COMM  = sal * 0.15 where SAL BETWEEN 50000 AND 79999; 
     UPDATE XX_TBEMP 
     SET COMM  = sal * 0.1 where SAL BETWEEN 80000 and 99999; 
END LOOP; 
END XX_UPDATECOMM; 
END XX_UPDATETBEMP;
