>                 Key: SPARK-31119
>                 URL: https://issues.apache.org/jira/browse/SPARK-31119
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 3.0.0, 3.1.0
>            Reporter: Kent Yao
>            Priority: Major
>
> {code:java}
> <extract expression> ::= EXTRACT <left paren> <extract field> FROM <extract source> <right paren>
> <extract source> ::= <datetime value expression> | <interval value expression>
> {code}
> We now only support datetime values as extract source for expression but it's alternative function `date_part` supports both datetime and interval.
> For ANSI compliance and the consistency between extract and `date_part`, we support intervals for extract expressions.
