hi everyone, as i know Es support create script field, running\_time filed while query by using painless. But can I create an script field like that by using SQL ?  
Example: select case when col1 = 1 then 2 else 0 end as col 2  
above, when I use query by SQL of ES it will create for me a col 2, but now I just want to call col 2 instead of create a computation for it.  
-\> select col 2  
how can I do that ?  
thanks and best regards

You can not. You need to use Painless.

thanks for your answer. i have one more question, is there any tool convert from SQL to painless ?  
EX: case when field1 = 'a' then 'b' else 'c' end.  
-\> painless: if (doc['field'] == 'a') { emit('b')} else {emit('c')}

Thanks and best regards.
