Question

这是我的oracle存储过程。我想将数据传递给过程时删除某些id，但是当我执行此过程时。我删除了我的trable所拥有的一切。

有人可以查看吗

CREATE OR REPLACE PROCEDURE Delete(
    id IN number)

AS
BEGIN
        DELETE FROM Users WHERE Users.id_user= id;
END;
/

我试图把：

DELETE FROM Users WHERE Users.id_user == id;

然后我收到编译错误。

Answer 1

你试过DELETE FROM Users WHERE id_user = id;吗？

使用==不是用于等式检查的有效SQL。

我仍然不明白为什么要删除所有行。 DELETE FROM Users WHERE Users.id_user = id应该正常工作。

有关DELETE STATEMENT语法的更多信息。

Answer 2

我有同样的问题。当我传递表中不存在的Id时，一切都会被删除。

如果表中存在id，则该过程将按照我希望它运行的方式运行。

PROCEDURE tests
( jobnr IN varchar2,
 x IN number,
 menu in varchar2 default '1')
IS
counter number := 0;

BEGIN
delete from table_test where jobnr = jobnr;

if sql%notfound or sql%rowcount=0 then
        rollback;
end if;

WHILE counter < x
LOOP
    insert into table_test ( cskey, telnr, seq, jobnr, menu ) values ('Test'||counter, counter, counter, jobnr, menu );
    counter := counter + 1;
END LOOP;
commit;

END;

Answer 3

尝试以下操作：将输入存储到本地变量中，然后在查询中使用此变量。这对我有用。

CREATE OR REPLACE PROCEDURE Delete(
    id IN number)

AS
v_id Number;
BEGIN
        v_id := id;
        DELETE FROM Users WHERE Users.id_user= v_id;
END;

Answer 4

CREATE TABLE USERS(ID NUMBER);

TABLE CREATED.

CREATE OR REPLACE PROCEDURE DeleteIDS(
    id IN number)

AS
BEGIN
        DELETE FROM Users WHERE id= id;
END;
/

PROCEDURE CREATED.

此处，在表中，用户ID存在，如果在过程声明中指定了id，则该过程将删除所有数据。所以，

CREATE OR REPLACE PROCEDURE DeleteIDS(
    idS IN number)

AS
BEGIN
        DELETE FROM Users WHERE id= idS;
END;
/
PROCEDURE CREATED.

现在，

INSERT INTO USERS VALUES(10);

1 ROW INSERTED.

INSERT INTO USER VALUES(20);

1 ROW INSERTED.

COMMIT;

现在，执行程序

SQL>EXEC DELETEIDS(10);

PL/SQL PROGRAM SUCCESSFULLY COMPLETED.

SELECT * FROM USERS;

ID
