Steven Hawkins commented on TEIID-4686:
---------------------------------------

> I would suggest making this as translator override and adding a note in the document about it, that way we can leave it for the user configuration.

Do you mean just disabling order by?  That is available already.  Or do you mean adding an override/capability specific to this scenario "supports order by multiple ..."?

> Issuing query like \[1\] causes an exception in PrestoDB. This seems to be PrestoDB issue. I found similar issue \[2\], but that one should be fixed. I have created a new issue \[3\]. Removing one column from ORDER BY, query returns correct result.
> Not sure if we can do something about it without avoiding pushing JOIN.
> I suggest either to fix this (if simple enough) or add a note to the documentation.
> \[1\]
> {code:sql}
> SELECT a.intkey, b.intkey FROM BQT1.SmallA AS a INNER JOIN BQT1.SmallB AS b on a.intkey = b.intkey ORDER BY 1, 2
> {code}
