dovecot - Nov 2013 - how to make quota per user ??

I use dovecot version 1.2.15 and i put quota for all users , now i want to
give more size for some emails , i already added the  quota to user database
, and i added the queries from http://wiki.dovecot.org/Quota/1.1
MySQL:
user_query = select uid, gid, home, \
  concat('*:bytes=', quota_bytes) as quota_rule \
  from users where userid = '%u'

# MySQL with userdb prefetch: Remember to prefix quota_rule with userdb_
# (just like all other userdb extra fields):
password_query = select userid as user, password, \
  uid as userdb_uid, gid as userdb_gid, \
  concat('*:bytes=', quota_bytes) as userdb_quota_rule \
  from users where userid = '%u'

but it is not work 
what i have to change and in which  files please ?

We use with v 2.1.17
user_query = SELECT maildir, uid, gid, concat('*:storage=', quota) AS
quota_rule, concat('Trash:storage=+', quota_trash) AS quota_rule2 FROM
mailbox WHERE username = '%u'
