Active Query Builder is a visual query builder component suite for Borland Delphi and C++ Builder which gives your end-users the ability to create complex queries via the intuitive visual interface.
The interface of Active Query Builder for Delphi is similar to either MS-Access or SQL Server visual query construction interface, but has much more possibilities than any other similar component. Such unique features of Active Query Builder like building queries with unions and subqueries make it the best solution for professional tasks.
Active Query Builder has full support of PostgreSQL dialect, including expressions with user defined data types, standard and user defined operators. For example:
Select OrderId is not Null, true or false, 1+ |/2+2
Where OrderName~~'qwe%' or '123'~'^1'
