I get the error as soon as I switch over from the SQL worksheet. For example, here are the steps I follow:
1) Run query 1 from worksheet:
Results show up in the results pane below
2) Add query 2 to worksheet:
Results show up in results pane as expected.
3) Click 'Query Builder' to build relationships
4) Receive Error Message as described earlier
Is it because I am running two queries on the worksheet?
My main objective is to be able to add tables and build relationships/queries via the Query Builder. Let me know if you think there is a different way to do this other than starting in the worksheet.
Thanks for the quick reply!
