4D for Mobile Tutorial – Define filter queries

For a mobile application, data is usually filtered to preserve storage space and provide direct and quick access to essential data.

With 4D, you have two types of filters.

  • A static filter to filter the data for a table. For example, limit to tasks with the status ‘in progress.’
  • A dynamic filter depends on the user’s information. For example, return only the user’s tasks.


This tutorial will show you how to use and combine these two filters.


Voilà! Now you know how to filter your data in your mobile application. To go further, you can continue with the blog or the documentation.
