Review Comment:
> The DATE type is used for values with a date part but no time part. MySQL retrieves and displays DATE values in 'YYYY-MM-DD' format. The supported range is '1000-01-01' to '9999-12-31'.
> The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in 'YYYY-MM-DD hh:mm:ss' format. The supported range is '1000-01-01 00:00:00' to '9999-12-31 23:59:59'.

Review Comment:
This argument is added in order to meet patterns like `cast(datev2 as datetimev2)`. Since datetimev2 has not been supported, this argument is indeed not used now.

Review Comment:
Maybe we do not support years before 1000. Although we could save it but could not support calculations. And maybe we could support it in the future.
