Maryann Xue updated CALCITE-992:
--------------------------------
Attachment: CALCITE-992.suggested.diff
I managed to put together the validation and sequence resolving stuff, but had
a little problem with making the RelOptTable a RexLiteral. The current patch
looks a bit ugly since the changes get everywhere in order to make RexLiteral
enclose this RelOptTable object. An alternative I'm thinking is to create a new
RexNode type, say, RexTableReference (or RexSequenceReference). Any
suggestions, [~julianhyde]?

> Currently the validator does not validate if the sequence exists or if the
> corresponding table is of the required type, etc. Also, in NEXT_VALUE and
> CURRENT_VALUE function, we need the sequence Table object instead of the
> sequence name string.
