dalongliu updated FLINK-27237:
------------------------------
Description:
This is an umbrella issue which is used to discuss the syntax enhancement about
partitioned table. These new syntaxes are very useful for partitioned tables,
especially for batch job.
Therefore, I propose to support the following statement about partitioned table:
{code:sql}
-- add partition
ALTER TABLE table_name ADD [IF NOT EXISTS] { PARTITION <partition_spec>
[PARTITION <partition_spec> ...] }
-- drop partition
ALTER TABLE table_name DROP [ IF EXISTS ] { PARTITION <partition_spec>
[PARTITION <partition_spec> ...] }
-- rename partition
ALTER TABLE table_name PARTITION <partition_spec> RENAME TO PARTITION
<partition_spec>;
-- show partitions
SHOW PARTITIONS table_name [PARTITION <partition_spec>]
<partition_spec>::
(partition_col_name=partition_col_val, ...)
{code}
