我有一个从选择查询调用的函数,下面是完美的函数。我想打电话给下面的步骤,如果布尔= 1是将值插入登录表:从函数PLSQL调用过程
create or replace FUNCTION isLoggedIn(x IN VARCHAR2, y IN VARCHAR2)
RETURN number IS
boolean number(1) := 0;
BEGIN
SELECT count(*) into boolean
FROM VIEWLOGIN
WHERE username = x AND password = y;
IF boolean = 1 THEN
PROCDURELOGIN
RETURN boolean;
ELSE
RETURN 0;
END IF;
END;
这是我的程序:
create or replace PROCEDURE PROCDURELOGIN
IS
BEGIN
INSERT INTO "SW3"."LOGIN" (LOGINID, MEMBERID)
VALUES (seqLogin.NEXTVAL, '1');
Commit;
END;
Create view VIEWLOGIN
SELECT firstname, surname, username, password
FROM member
但我得到的错误,当我运行查询:
Error starting at line : 1 in command -
SELECT firstname, surname, isLoggedIn(username, password)
FROM VIEWLOGIN
WHERE username = 'fionawalshe' AND password = 'qwertyu8'
Error report -
SQL Error: ORA-14551: cannot perform a DML operation inside a query
ORA-06512: at "SW3.PROCDURELOGIN", line 4
ORA-06512: at "SW3.ISLOGGEDIN", line 10
14551. 00000 - "cannot perform a DML operation inside a query "
*Cause: DML operation like insert, update, delete or select-for-update
cannot be performed inside a query or under a PDML slave.
*Action: Ensure that the offending DML operation is not performed or
use an autonomous transaction to perform the DML operation within
the query or PDML slave.
所以叫它。什么是问题? – OldProgrammer 2014-10-31 22:14:14
请编辑您的问题并添加VIEWLOGIN视图的来源。谢谢。 – 2014-10-31 22:22:07
