Debugging Error Opening "[SQL]" No Columns Returned

9 - Comet

I am executing SQL through Alteryx's Dynamic Data Input tool and receiving "Error Opening ... No Columns Returned" error messages.


In the past when I received this, it was due to the use of characters that Alteryx didn't like (E.g. "<>" was getting replaced with "__" in the behind the scenes Alteryx Editor.


I have ruled out syntax errors within the SQL by running it though Toad Data Point using the same driver.


Unfortunately, I cannot share the SQL code but am looking for more general help on how to debug.


Thank you.

Never mind.  I changed the data connection from an Oracle ODBC driver to Oracle OCI.  After doing that the error messages were more descriptive and pointed out that each query's schema were not quite identical.
