Active Query Builder is a true two-way visual query builder component for Delphi and C++ Builder that allows your end-users to build complex SQL queries via an intuitive visual interface easily. 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 and user-friendly interface that allows you to build queries involving unions and sub-queries.

The interface of Active Query Builder for Delphi 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 for Delphi such as the ability to build queries with unions and sub-queries make it the best solution for professional developers.

Active Query Builder supports Oracle, SQL Server, MS Access, MySQL, PostgreSQL, InterBase, Firebird, Informix, Sybase, SQLite, and ANSI-92 SQL dialects.

The sophisticated SQL parser with full Unicode support can translate any valid SQL statement into it's visual representation. You can use full range of database connectivity components as well as generic event-driven metadata provider to get metadata information from any data source.

Active Query Builder gives you full control over the SQL query - you can easily navigate it using the internal query builder objects. Using Active Query Builder you'll be able to retrieve various information about parsed query like lists of tables and fields used in the query. Working with parameters in Active Query Builder, you may know their names and data types, and discover to what database objects and fields they are related to.

The latest version of component allows you to substitute the user-friendly aliases for unintelligible names of your DB tables and fields. Though, your end-users can still build SQL scripts by hand: all the aliases used in query text will be automatically.
