[OpenSER-Users] [avp_db_query] How to analize resulting AVP's row by row?

Hi, in order to implement a ACL system for incoming calls I've created a table "acl" with those columns: - priority - from_username - from_domain - to_username - group_from - group_to - type | action In that tables I store rules, and my idea is to work as a firewall: the first match is ejecuted (action=ALLOW or action=REJECT) and exit. But I can't do it since I don't know how to use all the AVP's JUST for the first row, then for the second: avp_db_query("SELECT priority,from_username,from_domain,to_username,group_from,group_to,type,action FROM acl", "$avp(s:priority);$avp(s:from_username);$avp(s:from_domain);$avp(s:to_username);$avp(s:group_from);$avp(s:group_to);$avp(s:type);$avp(s:action)"); This query results in many rows, but I can't analize each row, I just can compare each AVP with a value, but for that AVP they are possible all the values of any row. Because this I'm thinking in using the "exec" module to call a system script. Is not possible to access to tjhe query result by rows? Thanks for any help. -- Iñaki Baz Castillo ibc(a)in.ilimit.es
