James Taylor commented on PHOENIX-3046:
---------------------------------------
Not sure - I think we need to try this in another database for the case when
col is null: {{WHERE col IS NOT LIKE '%'}}
Do you know offhand, [~julianhyde]? Would that always evaluate to false or if
col is null would it evaluate to true? Given the tri-logic wackiness, I suspect
WHERE null IS NOT LIKE '%' may evaluate to null.
> `NOT LIKE '%'` unexpectedly returns results
