Active Query Builder VCL Edition for Windows

Active Query Builder is a visual query builder VCL component (Borland Delphi, C++ Builder) that allows your end-users to build complex SQL queries via an intuitive visual query building interface. It differs from other SQL query builders by its parser that correctly handles SQL queries containing multiple nested joins and other fine points of SQL syntax. Another feature is the graphical engine that allows you to build queries visually involving unions and sub-queries. User-friendly interface allows you can access each union and sub-query in one-touch.

Active Query Builder supports SQL Server, MS Access, Oracle, MySQL, PostgreSQL, Interbase, and Firebird. The sophisticated Active SQL parser correctly handles multiple nested joins and other fine points found in some SQL dialects.
