oguzhan10 opened a new issue #8842: Cant creating chart in superset via Kylin
URL: https://github.com/apache/incubator-superset/issues/8842
 
 
   First of all, we connected Kylin to superset using Kylin's connection string. So we've been able to see Kylin tables in Superset. But when we try to create a chart we saw the error given below.  
   
   ![Ek Açıklama 2019-12-16 133227](https://user-images.githubusercontent.com/34449619/70899852-9cc1df80-2008-11ea-903d-1565424fb5c4.jpg)
   
   Then we changed the " /opt/rh/rh-python36/root/usr/lib/python3.6/site-packages/kylinpy/sqla_dialect.py " file. We changed initial code as shown above into configuration like that initial_quote=' ', escape_quote= ' '. 
   
   ```
       def __init__(self, dialect, initial_quote='"',
                    final_quote= None , escape_quote= '"', omit_schema=True):
           super(KylinIdentifierPreparer, self).__init__(
               dialect, initial_quote, final_quote, escape_quote, omit_schema
           )
   
   ```
   
   That's how we've been able to preview the table but then when we try to create a bar chart the problem remained and our query looked like that;

   However the same table and the same query is working when we use Impala as shown below.
