Thank you for your reply!
I did what you said but nothing changes in tableau prep. All string values are still missing. Could this be a bug?
Hi Li -
That seems like an odd issue. Is it happening with all the tables?
Have you tried a custom SQL for a specific customer to see if it does the same thing?
Yes this is happening with all the string types for all the tables.
It is an odd issue indeed. I am doing this for a school assignment but I seem to be the only with this problem. All other students see all values just fine.
