Stamatis Zampetakis created CALCITE-3188:
--------------------------------------------
Summary: IndexOutOfBoundsException in ProjectFilterTransposeRule when executing SELECT COUNT(*)
Key: CALCITE-3188
URL: https://issues.apache.org/jira/browse/CALCITE-3188
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.21.0
Reporter: Stamatis Zampetakis
Fix For: 1.21.0
The exception is raised by many tests in {{DruidAdapterIT}}.
What they all have in common is a query of the following form:
{code:java}
SELECT COUNT(*) FROM ...
{code}
where the query projects only a single column.
The stacktrace for {{DruidAdapterIT#testExpressionsFilterWithExtract}} is the following.
