Steven Hawkins commented on TEIID-3732:
---------------------------------------

Google spreadsheets had a similar issue. It affected even ordered comparisons there since null was treated as a low value, so that may need to be checked here.  Since Teiid does normalize / flatten the predicates prior to pushdown, this is valid workaround.

> This is related to TEIID-3573.     To add a support option so that when the translator  sees criteria like intNum<>1 it would need to produce "intNum<>1 and intNum IS NOT NULL". 
> This would negate the issue in JDG where it resolves intNum <> 1 to true when the column is null.
