急救,大侠,过程出错了!
CREATE OR REPLACE PROCEDURE vsvs(P_lotnumber xx_test_ta.a%TYPE)IS
BEGIN
UPDATE xx_test_employees SET salary = 0 WHERE employeeid = p_lotnumber;
END;
/
xx_test_employeeid表的结构为
C# code
employeeid name salary
001 五小越 1200
002 Wilson 1100
003 bryn 1200
004 Beng 5900
005 yes 12000
006 King 8900
xx_test_ta表的结构为
C/C++ code
A
001
002
003
004
005
006
C# code
DECLARE
v_name VARCHAR2(1000);
BEGIN
SELECT A INTO v_name FROM xx_kja_test_ta;
vsvs(v_name);
END;
结果报错了。Ora-01422:exact fetch returns more than requested number of rows
请问,如此写一个过程用来更新数据的!求求!谢谢
------解决方案--------------------
--你的查询语句返回的值多了,要用循环
DECLARE
v_name VARCHAR2(1000);
BEGIN
for i in (SELECT A FROM xx_kja_test_ta)
loop
vsvs(i.A);
end loop;
END;
