Active Query Builder is a .Net-ready ActiveX visual query builder component that allows your end-users to build complex SQL queries via an intuitive visual interface. It differs from other query builders by its powerful SQL parser that correctly handles SQL queries containing multiple nested joins and other fine points of SQL syntax. Another feature is the powerful graphical engine that allows you to build queries involving unions and sub-queries. The interface of Active Query Builder is similar to either MS-Access or SQL Server visual query construction interface, but is much more powerful compared to other similar components. The unique features of Active Query Builder such as the ability to build queries with unions and sub-queries make it the best solution for professional developers. Active Query Builder supports SQL Server, Oracle, MySQL, PostgreSQL, Interbase/Firebird, SQLite, and ANSI-92 SQL dialects. The sophisticated Active SQL parser can translate any valid SQL statement into it's visual representation. ActiveX Query Builder controls and iterfaces can be used in any software project which supports ActiveX controls as well as in the .Net projects. For example, you can use it with Visual Basic 6.0, Visual Basic .NET, Visual C++ 6.0, Visual C#, Delphi and so on. The component may be integrated into your application with just a few lines of code. ActiveX Query Builder can be used as a Windows Forms .NET control as easy as ActiveX control. You can simply work with the wrapper class that calls appropriate properties, methods and events from the COM dll. Using ActiveX Query Builder in .NET application you even don't need to register COM object server, so you can deploy your solutions without registration. The only thing you need is .NET Framework!There are two editions available: the Standard Edition and the Free Edition. The Free Edition is fully functional, but supports only the ANSI-92 SQL dialect.
