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 )
"""

English is not my native language. I try my best to express my thought precisely. I hope you understand what I mean. If any misunderstanding results from culture gaps, I apologize first.
