Review comment:
IIRC there was a discussion about it before and we decided to not making
`table` as a child for writing commands. The same applies to
`InsertIntoStatement`.
I can't clearly recall what the reason was, probably because we need to
strip `SubqueryAlias` for `table` in the writing commands.
