Re: Syntax of TIMESTAMP [WITHOUT TIME ZONE], TIMESTAMP WITH LOCAL TIME ZONE and TIMESTAMP WITH TIME ZONE in Calcite 1.17

Maybe you should review the fix for CALCITE-1947, which added this support. Also review SqlParserTest, which has a test for TIMESTAMP '2004-12-01 12:01:01.010234567890’ but not anything like "TIMESTAMP '2004-12-01 12:01:01 US/Pacific’. > On Nov 16, 2018, at 12:39 PM, Rui Wang wrote: > >

Re: WITH RECURSIVE implementation

There was a relevant discussion some months ago in the Calcite dev mailing list. Checkout the "Recursive query, graph query, Datalog" discussion. I guess representationally, extension should be easy. A plan becomes a graph instead of a tree. Cycles in the graph mean recursion. The tricky part is

WITH RECURSIVE implementation

I'm curious if anyone has any thoughts on how to go about implementing recursive queries. Postgres seems to only allow recursive queries with the form "non-recursive-term UNION [ALL] recursive-term" and uses a separate "recursive union" operator. Costing is also certainly a challenge since

Re: Charset support proposal

I agree that a change to RelDataTypeSystem is probably not necessary. But at the code level, we have to solve the following problem: there are many, many places where CHAR or VARCHAR types are created. Each of those will need to be assigned the correct char set. We need to make sure that those

Re: Charset support proposal

Thanks Stamatis for the comment and advice! You've made a good point on RelDataType. I agree RelDataTypeSystem change is not a necessity. I also agree with the work prioritization, the DDL changes are not urgent compare to core correctness. I'd like to create JIRA tickets on those topics which
