Start creating a query by selecting a query data source: drag-and-drop tables you want to work with from the Database Navigator pane into the Visual Query Builder area. The Visual Query Builder will appear on the right. To open Visual Query Builder click the Open Query Builder button in the SQL Editor tool bar. The tool creates SQL scripts automatically based on the visual schema you have created. Also, it can be helpful for those who are not very familiar with SQL scripting or if you do not want to insert script commands manually. It can be useful when you need to understand the various relationships between different tables. Query Builder is a user-friendly visualization tool that will help you make sense of your complex database designs.
