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.
