declare @queueid varchar(50)
declare @orderid varchar(50)
begin
set @tpid = (select tpid from inserted);
set @queueid = (select queueid from inserted);
set @orderid = (select orderid from inserted);

INSERT INTO dbeventtriggertable VALUES ('Query = WHERE tpid ='''+@tpid +''' and queueid = '''+@queueid +''' and orderid = '''+@orderid +''' ' );

END ;
