Restrictions When Using a MySQL Client
Remember the following restrictions when using a MySQL Client:
-
The relational tables using MySQL Client are not visible within the application. Therefore, you must create the tables and their relational links in the application if you intend to use the tables for segmentation or personalization.
-
When you add, update, or delete data in the relational tables using MySQL Client, the 'Table Field Updated' Journey trigger doesn't detect this event. Therefore, if you intend to use this trigger on a specific table, then you must use the application interface to add, update, and delete the data in that table.
