I am suprised it doesn't work since I use the techique all over the place. So if your existing query is: Select Name, TimeIN, TimeOUT from yourTable All you should have to do is: Select Name, TimeIN, IsNull(TimeOut,'') as 'TimeOut' from yourTable If you are using Sql server. If you ask me it is really best to handle this sort of thing on the database side in what you are passing to .net then try to handle it in .net. Ben
