[jira] [Created] (CALCITE-4689) EnumerableUncollectRule causes an IllegalArgumentException: Type mismatch: the field sizes are not equal

Thomas Rebele created CALCITE-4689:
--------------------------------------

             Summary: EnumerableUncollectRule causes an IllegalArgumentException: Type mismatch: the field sizes are not equal
                 Key: CALCITE-4689
                 URL: https://issues.apache.org/jira/browse/CALCITE-4689
             Project: Calcite
          Issue Type: Bug
    Affects Versions: 1.27.0
            Reporter: Thomas Rebele
         Attachments: Calcite4689.java

The EnumerableUncollectRule converts an Uncollect to an EnumerableUncollect. It does not set the itemAliases. This field is used to derive the row type in Uncollect#deriveUncollectRowType. Therefore the EnumerableUncollect has a different row type than the Uncollect.
