             Summary: Make COLUMN optional in ALTER TABLE
                 Key: SPARK-29633
                 URL: https://issues.apache.org/jira/browse/SPARK-29633
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Takeshi Yamamuro


In the mater, the query below fails;
{code}
create table tt3 (ax bigint, b short, c decimal) using parquet;
alter table tt3 rename c to d;
{code}

In PostgreSQL, we can make COLUMN optional;
{code}
ALTER TABLE [ IF EXISTS ] [ ONLY ] name [ * ]
    RENAME [ COLUMN ] column_name TO new_column_name
{code}
