Julian Hyde commented on CALCITE-4321:
--------------------------------------
I find that {{testJps}} fails when I use macOS's built-in JDK
(\{{/usr/bin/java}}) rather than a real JDK. I think it's unavoidable.
I'd be curious to know what's happening with {{testShift}}; maybe something
else JDK-specific.
> JDBC adapter omits FILTER (WHERE ...) expressions when generating SQL

> Key: CALCITE-4321
> URL: https://issues.apache.org/jira/browse/CALCITE-4321
> Project: Calcite
> Issue Type: Bug
> Components: jdbc-adapter
> Environment: MacOS 10.15, Java 11, PostgreSQL 12
> Reporter: Jeremiah Rhoads Hall
> Assignee: Julian Hyde
> Priority: Major
> Fix For: 1.27.0

>
> I tried out the PIVOT feature added in CALCITE-3752 and found what I think is
> a bug where the JDBC adapter will not generate `FILTER (WHERE ...)`
> expressions from relational expressions.
> Initially, I noticed that the SQL that was generated when trying out the
> pivot featue was missing the filter-where, but even when included directly in
> the Calcite SQL it's not in the SQL issued by the JDBC adapter.
> For example if I try to execute the following with Calcite:
> {code}
> select sum(amount) filter (where some_date_column = '2020-10-01') from
> my_table{code}
> The SQL issued by the adapter will be:
> {code}
> select sum(amount) from my_table
> {code}
> I have a small change here with a test case and a fix:
> https://github.com/apache/calcite/pull/2204
