    Description

      The following query is valid in Apache Spark.

      spark-shell
      
      scala> spark.sql("""select array(1, 2, 3)""")
      res1: org.apache.spark.sql.DataFrame = [array(1, 2, 3): array<int>]

      However, it would fail to parse in Apache Calcite

       

      AtomicRowExpression should not have ArrayConstructor for Apache Spark. Arrays are constructed by calling the array function (https://spark.apache.org/docs/latest/api/sql/index.html#array).

       

      array()
      array(1)
      array(1, 2, 3)
