Hi,

I am trying to use the elastic sql cli command. I setup an alias to cover multiple indexes, but now when I query via sql cli, I get the following:

sql\> select \* from all\_netflow\_indices limit 1;  
Bad request [Found 1 problem(s)  
line 1:15: [all\_netflow\_indices] points to indices [netflow-2018.07.16] and [netflow-2018.07.16] which have different mappings. When using multiple indices, the mappings must be identical.]

Hi @bossi6of9,

Thank you for taking ES SQL for a spin and reporting your finds.  
The error message is partially correct:

- to be able to query multiple indices, at the moment (we do have an [enhancement on our to-do list](https://github.com/elastic/elasticsearch/issues/31837)), they have to have identical mappings
- because of [this bug](https://github.com/elastic/elasticsearch/issues/31784), the error message incorrectly mentions the problematic indices' mappings and states the **same index twice**

I hope this clarifies better the issue you encounter.
