Julian Hyde commented on CALCITE-1940:
--------------------------------------
I'm not fond of introducing sub-classes of RexCall because there is a lot of
code that wouldn't know how to handle them. But in this case it seems to be the
least bad option.
This PR is converging, but not fast enough to make it into 1.14. Let's aim to
get this done for 1.15.
With 71 files changed, the PR is *much* larger than I expected. It seems that
there are changes to the life-cycle of dialects and handlers. I will need to
understand whether those changes are necessary or at least beneficial. I am on
vacation until tomorrow but will review again when I get back.
> Implement dialect specific support for sequences

> The Calcite parser and validator already supports sequences but the push down
> to the JDBC level is currently limited. SInce sequences are not supported on
> all DBMS every sql dialect should have the possibility to render it's own way
> of extracting sequence information or incrementing the value.
