austenhead commented on issue #3043: SQL Lab error in exporting .csv when query has duplicately named columns
URL: https://github.com/apache/incubator-superset/issues/3043#issuecomment-340536367
 
 
   I just upgraded to superset 0.20.4, and I'm still getting the same error that I reported above.
   
   ```
   -- this works in both the sql lab results tab and when exporting to a .csv
   SELECT 'a' AS a, 'a' AS b;
   ```
   
   ```
   -- this works fine in the sql lab results tab, but throws the 500 error when exporting to a .csv
   SELECT 'a' AS a, 'a' AS a;
   ```
   
   I get the same results as you when I click `Run Query` and look in the results tab (this was never an issue -- the results always appeared correctly in the results tab). I still get the error if I click the button that says `.CSV` after I run that query.
   
   Is there additional information that I can provide that would help figure out why we might be getting different results when I click the button that says `.CSV` to download the file to have a local .csv of the results output?
