Key advantages of Active Query Builder

  • Simple and clear visual SQL query building interface

    The interface of Active Query Builder is familiar to most database users. Users build queries mostly by mouse clicks. They add objects to the diagram by dragging them from the tree, select the needed fields and set their properties.

    Active Query Builder helps users to build SQL queries by giving them advice on object references, keeping away from common errors and warning them about problems. Working with Active Query Builder the user thinks about the data he/she needs to get, not about the SQL syntax correctness.

    Visual query builder lets design queries with sub-queries on separate tabs, edit their texts separately from the main query and preview the sub-query results.
