------------------------------------
Summary: CorrelateProjectExtractor does not handle nested field
accesses cor0.field0.field1
Key: CALCITE-7646
URL: https://issues.apache.org/jira/browse/CALCITE-7646
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.42.0
Reporter: Mihai Budiu
Assignee: Mihai Budiu
The decorrelator has a helper class called CorrelateProjectExtractor which
moves projections from the right side of a Correlate to the left side. However,
the helper ignores nested field accesses, assuming incorrectly that any field
access is an input field access. Such expressions should also be moved to the
left side.
