This page is for data modellers who want to configure a database table.

Overview

From a PhixFlow datasource, you can open a window listing the tables in that database. For example, in the datasource properties tab, in the toolbar click on

_datasource_show_tables
_datasource_show_tables
nopaneltrue
. The list shows the tables that the users defined in the datasource instances have permission to view. For each table, you can display:

  • the data in the table

  • a list of the attributes defined in that table

Depending on where you open the table list from, it will be either a simple list with only the name of each table, or a detailed list.

The database tables list has a toolbar with common buttons. You can export data from a detailed list using the
