Data Source Name does not show in drop down list after setting In-DB Connection

[NPham00]

Hi everyone,

i wanted to write in Maria DB, so i installed the necessary driver for Maria DB: https://help.alteryx.com/20213/designer/mariadb

After that i followed the setup of @jarrod (https://community.alteryx.com/t5/Alteryx-Designer-Discussions/Is-MariaDB-compatible-with-In-database...) and @PeterP (https://community.alteryx.com/t5/Alteryx-Designer-Knowledge-Base/Error-Data-source-name-not-found-an...). The connection is successfully tested.

However the DSN does not show in drop down list for selecting. I tried forcing this with connecting querry but i failed too (Error: No database selected). Someone has an idea, what is it about?

Yes it is. I can write in using Datastream-In or Output Tool but can't read it in the Table Query, so i thought there was no connection at all
