Xavier FH Leong commented on CALCITE-708:
-----------------------------------------
There's an alternate commit, think this is what you are looking for. And is the
Schema#getTypeInfo that we are looking for, where the RelDataTypeSystem can be
override to represent the underlying adapter connection.
Still work in progress, working on regression test. Let me know what you think
and I'll rebase later. Thanks.
