The evaluation version of AQT will return only 50 rows for a Select statement.
Once you have purchased a license you can reset this option in the options menu: Options > Display Options > Display Limits > Max Rows Displayed. We generally suggest not choosing "No limit" (except when you really need to) as your PC may run out of memory when doing Selects on very large tables.
You will probably also want to reset Max Col Size to 1000 at the same time.
