Review comment:
       Hi, this PR generally great, but i guess we still need to fill this class with some fields, i.e., database name etc.
   Therefore it is expected to visit the corresponding content by antlr visitor.
   You can choose to add that part in this PR or implement it in the next PR. How do you think?
