Question

我在DELTEK.MFG_BOM上创建了一个触发器，用于查找DELETK.MFG_BOM.MODIFIED_BY不在的表的UPDATE或INSERT（“C10863”，“M100133”，“M100196”，“M100273”，“ M100212“，”DELTEK“）

如果上述ID之一以外的某人更新或插入表中，它将发送电子邮件。

当用户测试时，他们会出现堕胎错误。这是什么原因。

这是我的触发器代码。

USE PRODCP7
GO
Create  TRIGGER DELTEK.MFG_BOM_MODIFIED_BY on DELTEK.MFG_BOM
AFTER INSERT , UPDATE  
AS
DECLARE @xml NVARCHAR(MAX)
DECLARE @body NVARCHAR(MAX)
Begin
    if exists (Select 1  From inserted Where MODIFIED_BY NOT IN ('C10863','M100133','M100196','M100273','M100212', 'DELTEK') )
    Begin

        SELECT Inserted.ASY_PART_ID, Inserted.ASY_PART_RVSN_ID, DELTEK.ITEM.ITEM_DESC, 
        Inserted.MODIFIED_BY, DELTEK.MI_CP_USER_NAME_LOOKUP.NAME, Inserted.TIME_STAMP into #Tmp
        FROM (Inserted 
        LEFT JOIN DELTEK.MI_CP_USER_NAME_LOOKUP ON Inserted.MODIFIED_BY = DELTEK.MI_CP_USER_NAME_LOOKUP.USER_ID) 
        LEFT JOIN DELTEK.ITEM ON Inserted.ASY_PART_KEY = DELTEK.ITEM.ITEM_KEY
        GROUP BY Inserted.ASY_PART_ID, Inserted.ASY_PART_RVSN_ID, DELTEK.ITEM.ITEM_DESC,
        Inserted.MODIFIED_BY, DELTEK.MI_CP_USER_NAME_LOOKUP.NAME, Inserted.TIME_STAMP
        HAVING Inserted.MODIFIED_BY Not In ('C10863','M100133','M100196','M100273','M100212','DELTEK')
        ORDER BY Inserted.ASY_PART_ID, Inserted.MODIFIED_BY;


        SET @xml = CAST(( SELECT ASY_PART_ID AS 'td','', ASY_PART_RVSN_ID AS 'td','', ISNULL(ITEM_DESC,'') AS 'td','', 
        MODIFIED_BY AS 'td','', ISNULL(NAME,'') AS 'td','', TIME_STAMP AS 'td',''
        From #Tmp a 
        FOR XML PATH('tr'), ELEMENTS ) AS NVARCHAR(MAX))

        SET @body ='<html><body><H3>Trigger Report Mail</H3>
        <table border = 1> 
        <tr>
        <th> ASY_PART_ID </th> <th> ASY_PART_RVSN_ID  </th> <th> ITEM_DESC </th>
        <th> MODIFIED_BY </th> <th> NAME </th> <th> TIME_STAMP </th> </tr>'    


        SET @body = @body + @xml +'</table></body></html>'

        EXEC msdb.dbo.sp_send_dbmail
        @profile_name = 'SQL Mail', -- replace with your SQL Database Mail Profile 
        @body = @body,
        @body_format ='HTML',
        @recipients = 'wasay@gmail.com', -- replace with your email address
        @subject = 'Email of Trigger Report on Table : DELTEK.MFG_BOM '  


    End
END

我实际上会创建一个队列来发布所有电子邮件和一个SP来发送电子邮件。

请参阅SQL Server Service Broker（https://msdn.microsoft.com/en-us/library/ms190495.aspx），其中处理队列的SP是发送电子邮件的SP。这种方式更清晰，您应该能够更轻松地调试代码。

顺便说一句，在上面的代码中，您不需要创建#Tmp表。只需在第二个查询中附加第一个选择。

由于触发器而获取事务中止错误
