--------------------------------------------
Summary: Fix matching predicate for JdbcProjectRule rule
Key: CALCITE-2253
URL: https://issues.apache.org/jira/browse/CALCITE-2253
Project: Calcite
Issue Type: Bug
Reporter: Volodymyr Vysotskyi
Assignee: Julian Hyde
In CALCITE-2206 was prevented pushing windowed aggregates down for the
{{SqlDialect}}s which do not support windowed functions.
After these changes, {{JdbcProjectRule}} is matched *only* for the cases when
{{SqlDialect}} supports windowed functions and project contains windowed
functions:
{code:java}
return out.dialect.supportsWindowFunctions()
&& !RexOver.containsOver(project.getProjects(), null);
{code}
