UNION queries: "Sorry, you don’t have permission to see that"


I am trying to create a native query with UNION statement inside. Database is MySQL 5.7.25.
This query works:
SELECT column1 FROM table1
SELECT column2 FROM table2;

However same query with WHERE conditions gives “Sorry, you don’t have permission to see that” error:
SELECT column1 FROM table1 WHERE column1=“column1”
SELECT column2 FROM table2 WHERE column2=“column2”;

Is there any way, I could UNION 2 different queries with WHERE conditions, using Metabase native query?

I cannot reproduce on 0.36.2 with MySQL 5.7

As for the log, there are just these 2 lines in the log:

@natalya So I guess that Google has removed that functionality from their version of MySQL. I cannot reproduce with 0.36.2 on regular MySQL 5.7

I see. Got it. Thanks for checking @flamber!
