I'm not familiar with InterBase, but the first thing I would try is running your query outside of ASP (straight through the DB) and see if it is working there. If it is not then we will need to modify the query, if it is then we need to look at the ASP.
Actually, I did all that before I post the message. I even run query directly from InteractiveSQL on IBConsole (I assume it's like MS Query Analyst). But it still won't show. That field is TIMESTAMP. I'm not sure if it's need specify format to do it. But thank you anyway.
