Answer 1

In your case the SQL Query before executed on the Server would be something like

Select * from table where USER_ID="Test1" AND USER_ID="Test2"...

So, are you sure there will be such records with USER_ID matching different filters. Perhaps you are required to use OR condition instead of AND condition
