Question

我在同一台服务器上有三个SQL Server数据库。之前，我必须使用查询在所有三个数据库上手动更新/插入。现在我想用触发器完成它。

我创建了一个触发器，但是在更新时，另一个表上的所有行都使用相同的数据进行了更新。

以下是更新不同数据库上其他表的触发器。

USE [QMS]
GO
/****** Object:  Trigger [dbo].[afterUserUpdate]    Script Date: 07/14/2015 12:19:39 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[afterUserUpdate] ON [dbo].[USERTBL] AFTER Update
AS
BEGIN 
  IF @@rowcount = 0 RETURN;
    Update QMSFL.[dbo].UserTBL SET USERID=b.USERID, USER_NAME=b.USER_NAME, USER_LEVEL=b.USER_LEVEL,
    PASSWORD=b.PASSWORD, USER_GRP=b.USER_GRP, STATUS=b.STATUS, MODIFY_BY=b.MODIFY_BY,MODIFY_DATE=b.MODIFY_DATE,LOGON_IND=b.LOGON_IND,
    SUPERVISOR_ID=b.SUPERVISOR_ID,STARTDATE=b.STARTDATE,RESIGNDATE=b.RESIGNDATE,COMPANY=b.COMPANY,PABXID=b.PABXID,branch=b.branch
    FROM QMSFL.[dbo].UserTBL a
    INNER Join inserted b ON a.UserID=b.UserID
    WHERE a.userid IN (SELECT userid FROM inserted) 

    Update QMSUC.[dbo].UserTBL SET USERID=b.USERID, USER_NAME=b.USER_NAME, USER_LEVEL=b.USER_LEVEL,
    PASSWORD=b.PASSWORD, USER_GRP=b.USER_GRP, STATUS=b.STATUS, MODIFY_BY=b.MODIFY_BY,MODIFY_DATE=b.MODIFY_DATE,LOGON_IND=b.LOGON_IND,
    SUPERVISOR_ID=b.SUPERVISOR_ID,STARTDATE=b.STARTDATE,RESIGNDATE=b.RESIGNDATE,COMPANY=b.COMPANY,PABXID=b.PABXID,branch=b.branch
    FROM QMSFL.[dbo].UserTBL a
    INNER Join inserted b ON a.UserID=b.UserID
    WHERE a.userid IN (SELECT userid FROM inserted) 
END

及以下是插入后触发器。尚未测试，导致我担心更新触发器会发生坏事。寻求你的建议这是好的。

USE [QMS]
GO
/****** Object:  Trigger [dbo].[afterUserInsert]    Script Date: 07/14/2015 12:31:59 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[afterUserInsert] ON [dbo].[USERTBL] AFTER INSERT
AS
BEGIN 
  IF @@rowcount = 0 RETURN;
    Insert Into QMSFL.[dbo].UserTBL (USERID,USER_NAME,USER_LEVEL,PASSWORD,USER_GRP,STATUS,MODIFY_BY,
    MODIFY_DATE,LOGON_IND,SUPERVISOR_ID,STARTDATE,RESIGNDATE,COMPANY,PABXID,branch)
    Select USERID,USER_NAME,USER_LEVEL,
    PASSWORD,USER_GRP,STATUS,MODIFY_BY,MODIFY_DATE,LOGON_IND,SUPERVISOR_ID,STARTDATE,RESIGNDATE,
    COMPANY,PABXID,branch From inserted
    Insert Into QMSUC.[dbo].UserTBL (USERID,USER_NAME,USER_LEVEL,PASSWORD,USER_GRP,STATUS,MODIFY_BY,
    MODIFY_DATE,LOGON_IND,SUPERVISOR_ID,STARTDATE,RESIGNDATE,COMPANY,PABXID,branch)
    Select USERID,USER_NAME,USER_LEVEL,PASSWORD,USER_GRP,STATUS,MODIFY_BY,MODIFY_DATE,LOGON_IND,
    SUPERVISOR_ID,STARTDATE,RESIGNDATE,COMPANY,PABXID,branch From inserted
END;

最后，是否可以在一次触发器中更新/插入后进行这些操作。并尽可能提供更新的工作触发器。

...谢谢=）

更新：简而言之，如何在一个触发器中更新多个表。

这将是我经过大量搜索和错误后完成的最终代码。按预期工作。可能对其他人有所帮助。
