Active Query Builder is a query builder component suite for Borland Delphi and C++ Builder which gives your end-users the ability to create complex queries via the visual interface. The interface is similar to either MS-Access or SQL Server query construction interface. Its graphical engine has the possibility to build queries with unions, nested joins and subqueries and its SQL parser correctly perceives multiple nested joins and other fine points. The component may be integrated with Delphi or C++ Builder application with a few lines of code.

Free Edition supports only ANSI-92 SQL dialect.
