oscarxanda opened a new issue #15814:
URL: https://github.com/apache/superset/issues/15814


   Assuming an account that has column level access defined in an AWS Data Lake.
   When using this account to connect to Athena, when Superset retrieves the 
table structure, it retrieves also the columns the user does not have access 
to. 
   The preview will also fail, as instead of the preview working by "SELECT 
*..." it does a "SELECT column_1, column_2...".
   
   ### Expected results
   
   Schema retrieval will only return the columns the account  has access to.
   Table preview will work by not adding the columns the account does not have 
access to.
   
   ### Actual results
   
   Table schema shows fields with no access.
   Preview mode fails.
   
   #### Screenshots
   
   Preview mode failing, schema showing the column "class" that the account 
does not have access to.

   #### How to reproduce the bug
   
   1. Create an account with column level permissions
   2. Create a DB connection using that account
   3. Go to SQL Lab
   4. Select a table the account has access to (but won't have access to all 
columns)
   5. See error
