     declare @id int; 
     declare @uid nvarchar(20); 
     declare @tentry datetime; 
     declare @tsn nvarchar(20); 
     declare @evtid nvarchar(20); 
     declare @audit_action nvarchar(300); 

select @idams = i.id from inserted i; 
select @id  = max(Rownumber) + 1 from TAV3.dbo.access_event_logs ; 
select @uid =i.USERID from inserted i; 
select @tentry =i.TIMESTAMPS from inserted i; 
select @tsn =i.TERMINALSN from inserted i; 
select @evtid =i.EVENTID from inserted i; 
set @audit_action='Inserted Record -- After Insert.'; 
set @tentry = dateadd(hh,3,@tentry); 


insert into TAV3.dbo.access_event_logs 
(Rownumber,Userid, Timeentry, Eventid, Terminalsn, Notes) 
values(@id,@uid, @tentry, @evtid, @tsn, @audit_action); 

update AMS_33.dbo.access_event_logs set Calculated=1 where id= @idams;

1）假定你是唯一一個行已被插入或更新，這可能是假的。 – automatic

如果我正確讀取您的代碼，您將通過此創建一個循環？！你有一個觸發器上的更新，你的觸發器再次更新這個表。你有任何錯誤？ – YvesR

我們假定你是唯一一個行已被插入或更新，像選擇@idams = i.id語句插入從我;

這可能是假的。然後，這些語句將永遠無法獲得的插入

我該如何克服這一點。 – user1703145

而不是使用插入的值條款使用一個選擇，即插入（fielda，fieldb）選擇inserted.foo作爲fielda，inserted.bar作爲插入的fieldb – automatic
