[jira] [Created] (CALCITE-5733) simplify should also simplify for array type

Xin Chen created CALCITE-5733:
---------------------------------

             Summary: simplify should also simplify for array type
                 Key: CALCITE-5733
                 URL: https://issues.apache.org/jira/browse/CALCITE-5733
             Project: Calcite
          Issue Type: Bug
    Affects Versions: 1.34.0, 1.26.0
            Reporter: Xin Chen


Simplification seem to not take into account that the specified field is of array type. In other words，it can simplify "a = 1 AND a = 2" to "false"，but can not simplify “a = [1,2] AND a = [2,3]” to "false". Obviously, was there no consideration given to the field type being an array？I found this issue while debugging the Flink SQL task.
