todd updated FLINK-22318:
-------------------------
Comment: was deleted
(was: I think it should be done in two steps, the first step is to extend the

Schema#UnresolvedColumn#columnName. The current columnName is of final type, I
need to remove the flinal keyword and add the setColumnName method at the same
time.)
> Support RENAME column name for ALTER TABLE statement
