表 A 上的触发器合并（更新插入）到表 B答案

【问题标题】：Trigger on Table A Does Merge (Upsert) into Table B表 A 上的触发器合并（更新插入）到表 B
【发布时间】：2017-10-26 19:17:14
【问题描述】：

我正在尝试向表 A 添加一个触发器，该触发器在执行插入或更新时对表 B 执行 upsert。我正在使用 MERGE 来完成此操作。

此数据库在 SQL Server 2008 R2 上运行。

这是我的脚本：

USE [XMPie]
GO

/****** Object:  Trigger [dbo].[tr_targetupd40836-09]    Script Date: 5/25/2017 10:18:30 AM ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO


CREATE TRIGGER [dbo].[tr_targetupd40872-01a]
ON [dbo].[40872-01]
after update, insert as

DECLARE @CJ int, @BPID int, @Email varchar(100)

IF (SELECT TOP 1 OptOut FROM inserted) = 1
BEGIN
    SELECT top 1 @CJ = CAST([MicrositeNumber] AS int) FROM inserted

    SELECT TOP 1 @BPID =  bp.BPID
            FROM JandLreporting.dbo.ControlJob cj
            INNER JOIN JandLreporting.dbo.BusinessPartner bp
            ON cj.JLMReferenceID = bp.JLMReferenceID
            WHERE cj.ControlJob = @CJ

    SELECT top 1 @Email = RTRIM(LTRIM(Email)) FROM inserted

    IF @BPID IS NOT NULL AND NOT EXISTS (SELECT * FROM [DoNotContactEmail] where Email = @Email and BPID = @BPID)
    INSERT [DoNotContactEmail](email, bpid) VALUES(@Email, @BPID)
END
ELSE
BEGIN
    MERGE JandLreporting.dbo.MicrositeResponseAdor AS T  
    USING inserted AS S 
    ON T.RecipientKey = S.RecipientKey
    WHEN MATCHED THEN 
         UPDATE set T.[MicrositeResponse_ID]= (s.[MicrositeResponse_ID])
        ,T.[MicrositeNumber]=LEFT(s.[MicrositeNumber],50)
        ,T.[RecipientKey]=LEFT(s.[RecipientKey],101)
        ,T.[Vin]=LEFT(s.[Vin],30)
        ,T.[FirstName]=LEFT(s.[FirstName],50)
        ,T.[MiddleInitial]=LEFT(s.[MiddleInitial],1)
        ,T.[LastName]=LEFT(s.[LastName],50)
        ,T.[FullName]=LEFT(s.[FullName],100)
        ,T.[Address1]=LEFT(s.[Address1],100)
        ,T.[Address2]=LEFT(s.[Address2],50)
        ,T.[City]=LEFT(s.[City],50)
        ,T.[State]=LEFT(s.[State],2)
        ,T.[ZipCode]=LEFT(s.[ZipCode],10)
        ,T.[PhoneNumber]=LEFT(s.[PhoneNumber],15)
    WHEN NOT MATCHED THEN  
      INSERT (T.[ID]
        ,T.[MicrositeResponse_ID]
        ,T.[MicrositeNumber]
        ,T.[RecipientKey]
        ,T.[Vin]
        ,T.[FirstName]
        ,T.[MiddleInitial]
        ,T.[LastName]
        ,T.[FullName]
        ,T.[Address1]
        ,T.[Address2]
        ,T.[City]
        ,T.[State]
        ,T.[ZipCode]
        ,T.[PhoneNumber]
        )
      VALUES (s.[ID]
        ,s.[MicrositeResponse_ID]
        ,s.[MicrositeNumber]
        ,s.[RecipientKey]
        ,s.[Vin]
        ,s.[FirstName]
        ,s.[MiddleInitial]
        ,s.[LastName]
        ,s.[FullName]
        ,s.[Address1]
        ,s.[Address2]
        ,s.[City]
        ,s.[State]
        ,s.[ZipCode]
        ,s.[PhoneNumber])
END

GO

当我尝试应用此触发器时，我收到以下错误：

Msg 102, Level 15, State 1, Procedure tr_targetupd40872-01a, Line 26 [Batch Start Line 9]
Incorrect syntax near ' '.

我不知道语法错误在哪里。任何帮助将不胜感激！

【问题讨论】：

将代码包装在BEGIN/END 中，看看是否能解决问题。
我应该在哪里开始？在创建触发器之前？
insert as begin 和 end 在末尾span>
create trigger 的正文周围。
@GordonLinoff 不走运。同样的错误。

【解决方案1】：

您需要将触发器的代码包装在BEGIN/END 中，如下所示：

CREATE TRIGGER [dbo].[tr_targetupd40872-01a]
ON [dbo].[40872-01]
after update, insert as
BEGIN --begin trigger
  DECLARE @CJ int, @BPID int, @Email varchar(100)

  IF (SELECT TOP 1 OptOut FROM inserted) = 1
  BEGIN
    SELECT top 1 @CJ = CAST([MicrositeNumber] AS int) FROM inserted

    SELECT TOP 1 @BPID =  bp.BPID
      FROM JandLreporting.dbo.ControlJob cj
        INNER JOIN JandLreporting.dbo.BusinessPartner bp
          ON cj.JLMReferenceID = bp.JLMReferenceID
      WHERE cj.ControlJob = @CJ

    SELECT top 1 @Email = RTRIM(LTRIM(Email)) FROM inserted

    IF @BPID IS NOT NULL AND NOT EXISTS (SELECT * FROM [DoNotContactEmail] where Email = @Email and BPID = @BPID)
    INSERT [DoNotContactEmail](email, bpid) VALUES(@Email, @BPID)
  END
  ELSE
  BEGIN
    MERGE JandLreporting.dbo.MicrositeResponseAdor AS T  
      USING inserted AS S 
      ON T.RecipientKey = S.RecipientKey
      WHEN MATCHED THEN UPDATE
        set T.[MicrositeResponse_ID]= (s.[MicrositeResponse_ID])
           ,T.[MicrositeNumber]=LEFT(s.[MicrositeNumber],50)
           ,T.[RecipientKey]=LEFT(s.[RecipientKey],101)
           ,T.[Vin]=LEFT(s.[Vin],30)
           ,T.[FirstName]=LEFT(s.[FirstName],50)
           ,T.[MiddleInitial]=LEFT(s.[MiddleInitial],1)
           ,T.[LastName]=LEFT(s.[LastName],50)
           ,T.[FullName]=LEFT(s.[FullName],100)
           ,T.[Address1]=LEFT(s.[Address1],100)
           ,T.[Address2]=LEFT(s.[Address2],50)
           ,T.[City]=LEFT(s.[City],50)
           ,T.[State]=LEFT(s.[State],2)
           ,T.[ZipCode]=LEFT(s.[ZipCode],10)
           ,T.[PhoneNumber]=LEFT(s.[PhoneNumber],15)
      WHEN NOT MATCHED THEN INSERT (
            T.[ID]
           ,T.[MicrositeResponse_ID]
           ,T.[MicrositeNumber]
           ,T.[RecipientKey]
           ,T.[Vin]
           ,T.[FirstName]
           ,T.[MiddleInitial]
           ,T.[LastName]
           ,T.[FullName]
           ,T.[Address1]
           ,T.[Address2]
           ,T.[City]
           ,T.[State]
           ,T.[ZipCode]
           ,T.[PhoneNumber]
        ) VALUES (
           s.[ID]

        )
  END
END  -- End of trigger
GO
