[jira] [Created] (CALCITE-7646) CorrelateProjectExtractor does not handle nested field accesses cor0.field0.field1

Mihai Budiu created CALCITE-7646:
------------------------------------

             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.
