-----------------------------------

             Summary: arrays_zip output unexpected alias column names
                 Key: SPARK-40292
                 URL: https://issues.apache.org/jira/browse/SPARK-40292
             Project: Spark
          Issue Type: Task
          Components: SQL
    Affects Versions: 3.4.0
            Reporter: Linhong Liu


For the below query:

 
{code:java}
with q as (
  select
    named_struct(
      'my_array', array(named_struct('x', 1, 'y', 2))
    ) as my_struct
)
select
  arrays_zip(my_struct.my_array)
from
  q {code}
The latest spark gives the below schema, the field name "my_array" was changed to "0"

 
root
 |-- arrays_zip(my_struct.my_array): array (nullable = true)
 |    |-- element: struct (containsNull = false)
 |    |    |-- 0: struct (nullable = true)
 |    |    |    |-- x: integer (nullable = true)
 |    |    |    |-- y: integer (nullable = true)
 
But the Spark 3.1 gives expected result
root
 |-- arrays_zip(my_struct.my_array): array (nullable = true)
 |    |-- element: struct (containsNull = false)
 |    |    |-- my_array: struct (nullable = true)
 |    |    |    |-- x: integer (nullable = true)
 |    |    |    |-- y: integer (nullable = true)
