Question

我有一个表，允许在我在该表中创建几个新列之前进入。该表调用UPDATE，DELETE和INSERT上的触发器，它在我使用History表中的相同列创建的日志历史记录表中插入数据。

现在不允许我在其显示的表格中插入数据。当我从编辑选项中编辑行时显示此错误.....

No row was Updated.
The data in row 1 was not committed 
Error Sources .net SQLClient Data Provider.
Error Message: Incorrect syntax near the keyword where 
Correct the error and retry or press esc to cancel

但如果我禁用触发器，一切正常。

触发

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER TRIGGER [magic  ].[magic  ]
ON magic
AFTER UPDATE, INSERT, DELETE
AS 
    DECLARE @operation CHAR(20) 
    SET @operation= 'N' 

    IF EXISTS(SELECT * FROM inserted) AND EXISTS(SELECT * FROM deleted) 
    BEGIN
        SET @operation = 'Updated'

        INSERT INTO magic.magic_HISTORY
            SELECT *, @operation 
            FROM INSERTED
    END

    IF EXISTS(SELECT * FROM inserted) AND NOT EXISTS(SELECT * FROM deleted)
    BEGIN
        SET @operation = 'Inserted'

        INSERT INTO magic.magic_HISTORY
            SELECT *, @operation 
            FROM INSERTED
    END

    IF NOT EXISTS(SELECT * FROM inserted) AND EXISTS(SELECT * FROM deleted)
    BEGIN
        SET @operation = 'Deleted'

        INSERT INTO magic.magic_HISTORY
            SELECT *, @operation 
            FROM deleted
    END

Answer 1

如果这是我的触发器，我会更改逻辑以使其更简单。首先，审计插入的值没有意义。你拥有魔术表中的所有值，因此拥有它的第二个副本是多余的。这使得审计更简单。您只需要担心之前表中的值。

ALTER TRIGGER [magic  ].[magic  ] on magic  
AFTER UPDATE, DELETE AS 

Declare @operation char(20) SET @operation= 'N' 

IF EXISTS(SELECT * FROM inserted) AND EXISTS(SELECT * FROM deleted) 
    SET @operation = 'Updated'

IF NOT EXISTS(SELECT * FROM inserted) AND EXISTS(SELECT * FROM deleted)
    SET @operation = 'Deleted'

INSERT INTO magic.magic_HISTORY
    SELECT  *,@operation FROM deleted

Answer 2

当您向magic.magic_HISTORY添加列时，您运行了：

ALTER TABLE magic.magic_HISTORY ADD column

如果是，那么改变：

INSERT INTO magic.magic_HISTORY
    SELECT  *,@operation FROM

到

INSERT INTO magic.magic_HISTORY (column list)
    SELECT  *,@operation FROM

Answer 3

您使用什么工具/应用程序来插入/更新到表中？您可以使用SQLProfiler捕获发送到数据库的特定SQL。也许在包装SQL中有一个语法错误，它会调用触发器。

另外，尝试在插入历史记录之前添加到触发器set nocount on，然后在set nocount off之后添加。这将减少驱动程序被来自触发器的“受影响行”消息混淆的可能性。

SQL Server触发器不允许插入数据或修改数据
