Active Query Builder VCL Edition is a visual query builder component suite that allows your end-users to build SQL queries with unions and sub-queries via an intuitive visual interface.

Ability to compile the component with DevExpress VCL controls or with Unicode-enabled visual controls from TNT Library
Compilation of Active Query Builder with third-party controls will enable you to perfectly match the appearance of the component with the rest of your application. Compilation of Active Query Builder with TNT library will allow you to take advantage of the Unicode-enabled visual query building with any Delphi or C++ Builder IDE version. Please note that this ability is available for the customers of the component with the source code only as far as required for re-compilation with the third-party packages.

BDE, ADO, dbExpress, IB Express, Zeos and many other Delphi database connectivity components and custom metadata providers.
We are planning to create metadata providers for all popular database connectivity components but, of course, we cannot cover them all. Thus, we provided for the other ways to load metadata to the query builder from any data source. By using them, you can work disconnected, providing all the necessary metadata information by yourself. (You can learn more about the different ways to load metadata at the Load Metadata demo project that is included in the Trial version)
