Select query return null only when I add TimeStamp column

Hello experts!

I’m new with ignition. I’m trying to practice some named query for training purpose. I set connection with MS SQL server database and I was able to get data using SELECT named query. My problem is when I add EventTimeStamp column, the query don’t return result however when I’m running this query in SSMS it return result.
Thanks in advance!

What if you use just ConditionEvent in your from statement?

Thank you for replying, I tested it but same result.
