Merge User , really sufficient ?

In domergeuser2.php , the merge user script only update these tables :
ubbt_USER_PROFILE
ubbt_TOPICS
ubbt_POSTS
ubbt_FILES
ubbt_POLL_DATA
ubbt_PRIVATE_MESSAGE_TOPICS
ubbt_PRIVATE_MESSAGE_POSTS
ubbt_PRIVATE_MESSAGE_USERS
ubbt_SHOUT_BOX

delete :
ubbt_USERS
ubbt_USER_PROFILE
ubbt_USER_DATA
ubbt_USER_GROUPS
ubbt_FORUM_LAST_VISIT

But there are other tables that contains USER_ID that is not cleaned / modified , such as :
ubbt_BANNED_USERS (delete ?)
ubbt_CALENDAR_EVENTS (delete ?)
ubbt_MODERATORS (delete ?)
ubbt_RATINGS where RATING_TYPE = 'u' (delete ?)
ubbt_WATCH_LISTS where WATCH_TYPE = 'u' (delete ?)
... (maybe there're still others missed here)

Is it ok to leave these 'zombie' data ?
When migrating to 8.0 , will there be a 'clean-up' script that scans the whole integrity of the db ?

Good question.
We currently have issues over the different versions with orphaned data/files.
It would be nice to have something to clean them all up.
Including file attachments and gallery items.

Are these codes sufficient ? (groovy codes , but easy to understand)

Code:


db.execute """
  delete from ubbt_BANNED_USERS
  where USER_ID = $fromUser
"""

db.execute """
  delete from ubbt_CALENDAR_EVENTS
  where USER_ID = $fromUser
"""

db.execute """
  delete from ubbt_RATINGS
  where RATING_RATER = $fromUser or ( RATING_TYPE = 'u' and RATING_TARGET = $fromUser)
"""

db.execute """
  delete from ubbt_CALENDAR_EVENTS
  where USER_ID = $fromUser
"""

db.execute """
  delete from ubbt_WATCH_LISTS
  where USER_ID = $fromUser or ( WATCH_TYPE = 'u' and WATCH_ID = $fromUser )
"""

well, technically that works, but if you are merging a banned user into a non-banned one you might OR the ban state?

same idea for the other ones...

so YES, delete removes all traces of former, but doesn't truly then MERGE

you might think of UPDATE queries and REPLACE INTO queries if you truly want to merge..

in the end, your queries are good for a removal of the former self though
