[jira] [Created] (SPARK-36022) Respect interval fields in extract

Max Gekk created SPARK-36022:
--------------------------------

             Summary: Respect interval fields in extract
                 Key: SPARK-36022
                 URL: https://issues.apache.org/jira/browse/SPARK-36022
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Max Gekk


Extract should process only existing fields of interval types. For example:

{code:sql}
spark-sql> SELECT EXTRACT(MONTH FROM INTERVAL '2021-11' YEAR TO MONTH);
11
spark-sql> SELECT EXTRACT(MONTH FROM INTERVAL '2021' YEAR);
0
{code}
The last command should fail as the month field doesn't present in INTERVAL YEAR.
