Hello avp_db_query(query[,dest]) can get a database query and store the results in the avps. But what if the results returns many rows,and how can I get all the results? How to set the [dest] parameter ? I've tried the method describered inhttp://www.kamailio.org/docs/avp_db_query.html,but it doesn't work. like below mysql<select mem_user from tgroup where grp_name='1234'; +----------+ | mem_user | +----------+ | 1013 | | 2013 | +----------+ 2 rows in set (0.00 sec) kamailio.cfg if(avp_db_query("select mem_user from tgroup where grp_name='1234'","$avp(name)")) { xlog("L_INFO","query results[1] :$avp(name[1])\n"); xlog("L_INFO","query results[2] :$avp(name[2])\n"); } syslog <INFO> query results[1] :<null> <INFO> query results[2] :<null> version: kamailio 3.0.2 MySQL 5.0 thank you very much!
