 ### Added
 
+- Added `Unqualified()` method to generated column structures that returns columns without table alias/prefix.
 - Added `PreloadCount` and `ThenLoadCount` to generate code for preloading and then loading counts for relationships. (thanks @jacobmolby)
 - MySQL support for insert queries executing loaders (e.g., `InsertThenLoad`, `InsertThenLoadCount`). (thanks @jacobmolby)
 - Added overwritable hooks that are run before the exec or scanning test of generated queries. This allows seeding data before the test runs.
