Active Query Builder is a free component suite that provides an intuitive visual interface for end-users to create complex SQL queries. Compatible with almost any software, it simplifies the query building process for users of all levels.

The tool’s graphical engine is another notable feature, allowing users to construct queries that involve 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 more powerful when compared to similar tools. Its unique features make it the best solution for professional developers who need the ability to build complex queries with unions and subqueries.
Active Query Builder is a true two-way query builder, seamlessly combining visual query building with direct SQL query editing. Changes made to the SQL query text will be reflected on the query builder instantly. It also provides a way to customize the SQL code to meet your specific requirements. A lot of properties are available to help you customize the resulting SQL query representation by specifying when to move to the next line, to increase the indent, to wrap a line; the tool provides precise control over the SQL output.
This powerful solution may be easily integrated into your application with just a few lines of code. Unlike many other query building solutions, Active Query Builder does not force you to use specific tools. Instead, it allows you to incorporate any accompanying tools into your application quickly and effortlessly. The product is shipped with a detailed help system and a demo application to speed up the learning curve.
Active Query Builder comes as a Delphi VCL component, as an ActiveX control or a Windows.Forms .NET component. Hence, it can be used across various software development platforms and is absolutely free, even for commercial purposes. Overall, Active Query Builder remains one of the best query builders available for those who require a user-friendly interface, the ability to create complex queries, and support for multiple programming languages.
