[jira] [Created] (CALCITE-4913) Correlated variables in a select list are not deduplicated

Konstantin Orlov created CALCITE-4913:
-----------------------------------------

             Summary: Correlated variables in a select list are not deduplicated
                 Key: CALCITE-4913
                 URL: https://issues.apache.org/jira/browse/CALCITE-4913
             Project: Calcite
          Issue Type: Bug
    Affects Versions: 1.28.0
            Reporter: Konstantin Orlov


Currently, the deduplication of correlated variables ain't done for correlates in select list. Looks like the root cause here is same as for CALCITE-4673, but, unfortunately, suggested patch has addressed only the particular problem with a table function. It would be great to provide a more gereric fix.

Besides, the project rel doesn't expose any correlated variables that should be set by this node
