[Ibis] BUG: OmniSciDB - Fix the default `else_` for the `when` operation #129

Open kcpevey opened 3 years ago

kcpevey commented 3 years ago

Currently, the default omniscidb else_ operation, combined with when, is given a wrong translation CAST(NULL AS STR). maybe it is an old implementation and it should be updated. IIRC, OmniSciDB didn't have literal NULL support some years ago. probably, it can be translated directly to NULL.

This was a bigger issue than originally thought. @xmnlab is in progress, but it's currently on hold.

There is a workaround available to get around this.
