OQBuilder is a freeware software that comes with full source code. It is a simple tool for creating and executing SQL queries.
The good news is that all versions of Open QBuilder are available as freeware with full source code and samples. If you want to create new TOQBEngine-descendants to work with any DataSet-oriented sources such as OCI engine, etc., you can do so easily with OQBuilder. Once you have created your own OQBEngineXXX, it is possible to share them with the Delphi and C++Builder developers' community by contacting the OQBuilder team. Your engine will be added to the web-page and should be saved as freeware with full source code.
Saving and loading query models is another useful feature provided by OQBuilder. The OQBuilder query format resembles an ".ini file" and can be customized in methods procedure TQBForm.btnSaveClick (model saving) and procedure TQBForm.btnOpenClick (model loading). The first limited public version of QBuidler for Delphi 1&2 was released in 1996.
All in all, if you are a developer or programmer looking for a powerful yet easy-to-use visual query builder, look no further than Open QBuilder with its full-fledged source code and samples.
