You need to specify the database in the select. For example: SELECT * FROM mudbank.mytbl ...

im using this char query[] = "SELECT * FROM RunningPrintJobs;";
So, add the database. :)
Mydbnamegoeshere.RunningPrintJobs

right so i added this :
char query[] = "USE PH123048_printtracker; SELECT * FROM RunningPrintJobs";
getting this

No, don’t use the use clause. You must add the dB name as I’ve suggested.
SELECT * FROM PH123048_printtracker.RunningPrintJobs
You cannot combine queries.

im sorry brains not working today, that removed the db error now im getting a
Memory error
Are you following the example sketch to read the columns and rows?
If you can’t figure it out, you can send me your sketch and I’ll look at it when I get some time to tinker.

I tested your sketch. The only thing I changed was I used IP to connect since DNS doesn't work reliably on my mobile network. And I changed the query to SELECT from world.city ... limit 10. Worked fine. I am also using MySQL 8.0.13.
Try again using IP to connect. If that doesn't work, try a newer version of MySQL.
What board are you using?
I have a patch ready to test. Would you like to try it out? If so, please PM me at d r c h a r l e s b e l l at g m a i l dot c o m. I'll send you a .diff which you can apply to the latest code in github (may not apply to the one from library manager).
Surely,
If you include ESP32 I can test that too. Otherwise I start with ESP8266
