[Users] AVPs iteration

Hi all, In the pseudo variables docs page: $avp(id[N]) - represents the value of N-th AVP identified by 'id'. This means if i do an avp_db_query that return N avps i can access to the value of avps with $avp(id[N]). But if i don't know how many record are returned from the query how can i iterate over an array of avps ? I've something like: avp_db_query("SELECT n.number,n.type,n.translated FROM numerations AS n, users AS u, associations AS a WHERE a.numeration_id = n.id AND a.user_id = u.id AND u.lid = '$tU'","$avp(cli);$avp(type);$avp(translated)") so i can access to the record with $avp(cli[0]) $avp(cli[1]) etc.. i want to append all contact returned to the destination uri and with the record $avp(translated) "true" i want to do some processing. but if i can't iterate over array of avps it's difficult. thanks, :tele
