Hello Xing,
No I will not be maintaining a customized `SqlImplementor`, rather I'll be
making changes in the existing `SqlImplementor`.

Regarding 3122. The fix looks good to me, but one test is broken when I merge
in the fix to [CALCITE-3138] "RelStructuredTypeFlattener doesn't restructure
ROW type fields”.
So, we are holding until I figure with Khai Tran (author of 3122) and Igor
Guzenko (author or 3138) out how to combine
I might be mistaken, but disabling stripCastFromString() for some dialects and
not others doesn’t sound like it’s solving the root cause of the problem.

Hi Julian,
2 tests failed when I made the stripCastFromString() no-op.
1.
testDb2DialectSelectQueryWithGroup
2.
testSelectQueryWithGroup
Above tests pretty much do the same thing and basically strip the cast from
String literal something like this:
Expected:
SELECT COUNT(*),
Hey,
I am trying to optimize queries by creating materialized views in Hive and
then exposing them to Calcite for optimized query rewrite.
I wanted to know that how mature is the spark adapter of Calcite i.e. Let's
say while making the connection I set parameter spark=true

Thanks for your work, Stamatis.
As for 1581, I have reviewed it and it looks good to me. So I am +1 for the
change.

Hi Julian,
thank you very much for your insights.
Your analysis is very detailed and I agree with all your suggestions.
For myself I started to realize the "big" differences between Calcites Use Case
and the PLC4X Case.
I will definitely have a look into the book advised by you (I like
Hmm,, I get it
So maybe you can try HepPlanner with match order of BOTTOM_UP;
Or if VolcanoPlanner is necessary, how about call the optimization multiple
times, e.g. wrap it with a loop

Summary: Add strcmp function

Project: Calcite
Issue Type: Improvement
Reporter:
I guess in your approach, you need to maintain a customized
`SqlImplementor` ?
How about add a RelOptRule and detect pattern of "date + interval '1' DAY"
and use a RexShuttle to convert to "target_func(date, interval '1' DAY)"
Thus only a RelOptRule needs to be maintained.
