-----------------------------
Resolution: Duplicate
> Extend ALTER TABLE DROP PARTITION syntax to use all comparators
> ---------------------------------------------------------------
>
> Key: SPARK-23866
> URL: https://issues.apache.org/jira/browse/SPARK-23866
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: Dong Jiang
> Priority: Major
>
> Please add SQL support equivalent to drop multiple partitions by operators
> other than =, basically equivalent of
> https://issues.apache.org/jira/browse/HIVE-2908
> "To drop a partition from a Hive table, this works:
> ALTER TABLE foo DROP PARTITION(ds = 'date')
> ...but it should also work to drop all partitions prior to date.
> ALTER TABLE foo DROP PARTITION(ds < 'date')
> This task is to implement ALTER TABLE DROP PARTITION for all of the
> comparators, < > <= >= <> = != instead of just for =."
