It appears that the columnstore backend is coded to support this, but as far as I can tell, it's never been tested. The 10.1 frontend also appears to have support, but it syntaxes when this parameter is added. There are no tests in the regression suite for IGNORE or RESPECT NULLS.

dleeyh Do you have test for IGNORE/RESPECT NULLS ?

No, I don't.

It would be great to have this supported as it is impeding upgrades from 1.0 to 1.1.
