SQL 服务器触发删除到单个 Table

Question

我想在我的数据库中的每个 table 上创建一个触发器，它将删除的数据的副本记录到我可以引用的单个 'Audit' table 中。

我环顾四周，但由于列定义不同，似乎无法找到将其全部插入单个 table 的方法。

非常感谢任何帮助。

谢谢

这是示例代码。我在这里做的是用户在 table 上所做的非常更新我从 Deleted 和 Inserted table 获取新旧值 sql 在我们更新 [=14] 时维护=] 。对于 delete 的情况，我想你可以从 deleted 中得到它。

  ALTER TRIGGER [SIR].[TESTTABLE_UPDATE]
        ON [DBO].[TESTTABLE]
  AFTER UPDATE
  AS
  BEGIN
         IF (@@ROWCOUNT  = 0)  return SET NOCOUNT ON; DECLARE @USER VARCHAR(1000)  
         -- this is a function which can gives u current loggined user in case if someone update the data from backend we can get that user name and log it.
         SET @USER='' SET @USER= (select dbo.GetCurrentUserName())  

         --this is a filter for bulk update which systemm does and you dont care about it so return 
         if( PATINDEX('%workerprocess%',@USER)>0) return 

         DECLARE  @ID INT , @LOGS VARCHAR(MAX)  , @FINALLOGS VARCHAR(MAX)      DECLARE @ACTION VARCHAR(MAX)       
         SET @ACTION =''       SET @LOGS=''      SET @FINALLOGS =''  
         SELECT  @LOGS = DELETED.CHANGELOG FROM DELETED
    -- individual column that a table contain 
    IF UPDATE([STATECODE])
        BEGIN
            SET @Action += '|  StateCode Changed from '+convert(varchar, ( select isnull( [STATECODE],'') FROM deleted   )) +'  to  '+ convert(varchar, ( select isnull( [STATECODE],'') FROM inserted  ))  +' | '
        END
   -- individual column that a table contain 
    IF UPDATE([FACILITYCODE])
        BEGIN
            SET @Action += '|  FacilityCode Changed from '+convert(varchar, ( select isnull( [FACILITYCODE],'') FROM deleted   )) +'  to  '+ convert(varchar, ( select isnull( [FACILITYCODE],'') FROM inserted  ))  +' | '
        END

    IF UPDATE([INSTALLATIONCODE])
        BEGIN
            SET @Action += '|  InstallationCode Changed from '+convert(varchar, ( select isnull( [INSTALLATIONCODE],'') FROM deleted   )) +'  to  '+ convert(varchar, ( select isnull( [INSTALLATIONCODE],'') FROM inserted  ))  +' | '
        END


             set @FINALLOGS =' [SIR.INSTALLATIONS Updated  On ' +  CONVERT(varchar(25), GETDATE()) + @ACTION + ISNULL( @LOGS,'') +' ] '



             -- this is my audit table where I am logging everything.
             INSERT INTO SIR.UserChangeLog (UpdatedBy,ChangeLog)  VALUES(@user, @FINALLOGS)
  END

创建审核 table:

CREATE TABLE [dbo].[MyAudit](
    [id] [int] IDENTITY(1,1) NOT NULL,
    [TableName] [nvarchar](100) NOT NULL,
    [ColumnName] [nvarchar](100) NOT NULL,
    [DeletedValue] [sql_variant] NULL,
    [ChangeDateTime] [datetime] NOT NULL,
)
GO
ALTER TABLE [dbo].[MyAudit] ADD  CONSTRAINT [DF_MyAudit_ChangeDateTime]  DEFAULT (getdate()) FOR [ChangeDateTime]

将触发器添加到每个 table 您想要记录删除的内容：

CREATE TRIGGER [MyTrigger] 
   ON  [MyTable]
   AFTER DELETE
AS 
BEGIN
    SET NOCOUNT ON;
    Insert into [MyAudit] ([Tablename], [ColumnName], [DeletedValue])
        Select 'MyTable', 'Column1', deleted.Column1 from deleted
    Insert into [MyAudit] ([Tablename], [ColumnName], [DeletedValue])
        Select 'MyTable', 'Column2', deleted.Column2 from deleted
--Do all columns until column x
    Insert into [MyAudit] ([Tablename], [ColumnName], [DeletedValue])
        Select 'MyTable', 'ColumnX', deleted.ColumnX from deleted
END
