Question

I am using SQL Server 2008. My trigger shown below. And I am inserting the values I didn’t get any update in two tables .

 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

Here no insert or update is performing ?

Answer 1

You are assuming only one row has been inserted or updated, in statements like
select @idams = i.id from inserted i;

That could be false. Those statement would then fail never getting to the insert
