Question

我正在使用SQL Server 2008.我的触发器如下所示。我正在插入两个表中没有得到任何更新的值。

 CREATE TRIGGER trgAfterInserta ON AMS_33.dbo.access_event_logs
 AFTER INSERT,UPDATE 
 AS           
        declare @idams bigint;  
        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;

GO

表1 AMS_33.dbo.access_event_logs

  id    bigint  Unchecked
  USERID    nvarchar(50)    Unchecked

  RECLOGFROMIP  nvarchar(50)    Unchecked
  LOCALTIMESTAMP    datetime    Unchecked
  PhotoPath nvarchar(50)    Checked

表2 TAV3.dbo.access_event_logs

Rownumber   int Unchecked
Userid  nvarchar(20)    Unchecked
Timeentry   datetime    Unchecked
Eventid nvarchar(20)    Checked
Terminalsn  nvarchar(20)    Unchecked
Calculated  int Checked
Notes   nvarchar(300)   Checked

此处没有执行插入或更新？

Answer 1

您假设在语句中只插入或更新了一行从插入的i中选择@idams = i.id;

这可能是错误的。那些声明将永远无法进入插入

SQL Server触发器插入和更新操作不起作用？
