Active Query Builder has complete support of Oracle, Microsoft SQL Server, MySQL, PostgreSQL, InterBase, Informix and more SQL dialects and can be integrated with your application by setting a few properties or adding a few lines of code.

Updates in 1.17

Behavior changes

  • The Select checkbox is checked automatically now on adding a new expression.
  • Grouping is set automatically now on specifying the aggregate for a column now.
  • The numbers entered into condition for string fields are treated as literals.
  • The "=TRUE" condition is set automatically on adding a logical expression now. Useful on adding the EXISTS expressions.
  • Automatic alias assignment is made when user adds two or more columns with same name to the query. The warning message is shown when multiple columns with same name appear in sub-queries in result of user actions as this may lead to inconsistence in the calling sub-query.
  • The new UserMessage event is added. It is fired when the Query Builder is about to show the warning message to the user. You may override this behavior by handling this event.
