Hi I'm using Kamailio v1.5.1 and, I do not know why, the avp value is disappearing. Let me show you what is happening: #IT DOESN'T WORK avp_db_query("select count(1) as c from group_endpoint where num_ip='$si'","$avp(i:105)"); log(1,"Before AVP_PRINT\n"); avp_print(); log(1,"After AVP_PRINT\n"); if( avp_check("$avp(i:105)","eq/i:0") ) #Debug Jun 10 09:57:48 [4326] DBG:avpops:ops_dbquery_avps: query [select count(1) as c from group_endpoint where num_ip='192.168.0.194'] Jun 10 09:57:48 [4326] DBG:core:db_new_result: allocate 28 bytes for result set at 0x8180ea8 Jun 10 09:57:48 [4326] DBG:db_mysql:db_mysql_get_columns: 1 columns returned from the query Jun 10 09:57:48 [4326] DBG:core:db_allocate_columns: allocate 4 bytes for result names at 0x8180ed0 Jun 10 09:57:48 [4326] DBG:core:db_allocate_columns: allocate 4 bytes for result types at 0x8180ee0 Jun 10 09:57:48 [4326] DBG:db_mysql:db_mysql_get_columns: allocate 8 bytes for RES_NAMES[0] at 0x8180ef0 Jun 10 09:57:48 [4326] DBG:db_mysql:db_mysql_get_columns: RES_NAMES(0x8180ef0)[0]=[c] Jun 10 09:57:48 [4326] DBG:db_mysql:db_mysql_get_columns: use DB_BIGINT result type Jun 10 09:57:48 [4326] DBG:core:db_allocate_rows: allocate 8 bytes for rows at 0x8180f00 Jun 10 09:57:48 [4326] DBG:core:db_allocate_row: allocate 20 bytes for row values at 0x8180f10 Jun 10 09:57:48 [4326] DBG:core:db_str2val: converting BIGINT [0] Jun 10 09:57:48 [4326] DBG:avpops:db_query_avp: rows [1] Jun 10 09:57:48 [4326] DBG:avpops:db_query_avp: row [0] Jun 10 09:57:48 [4326] DBG:avpops:db_close_query: close avp query Jun 10 09:57:48 [4326] DBG:core:db_free_columns: freeing 1 columns Jun 10 09:57:48 [4326] DBG:core:db_free_columns: freeing RES_NAMES[0] at 0x8180ef0 Jun 10 09:57:48 [4326] DBG:core:db_free_columns: freeing result names at 0x8180ed0 Jun 10 09:57:48 [4326] DBG:core:db_free_columns: freeing result types at 0x8180ee0 Jun 10 09:57:48 [4326] DBG:core:db_free_rows: freeing 1 rows Jun 10 09:57:48 [4326] DBG:core:db_free_row: freeing row values at 0x8180f10 Jun 10 09:57:48 [4326] DBG:core:db_free_rows: freeing rows at 0x8180f00 Jun 10 09:57:48 [4326] DBG:core:db_free_result: freeing result set at 0x8180ea8 Before AVP_PRINT After AVP_PRINT Jun 10 09:57:48 [4326] DBG:avpops:ops_check_avp: no src avp found No src avp found! There isn't any avp. The avp value returned by mysql server is quickly dropped. So, to avoid this, I changed the query's result into a string. I'm using the mysql concat function. #IT WORKS! avp_db_query("select concat('',count(1)) from group_endpoint where num_ip='$si'","$avp(s:105)"); log(1,"Before AVP_PRINT\n"); avp_print(); log(1,"After AVP_PRINT\n"); if( avp_check("$avp(s:105)","eq/s:0/g") ) #Debug Jun 10 10:01:37 [4378] DBG:avpops:ops_dbquery_avps: query [select concat('',count(1)) from group_endpoint where num_ip='192.168.0.194'] Jun 10 10:01:37 [4378] DBG:core:db_new_result: allocate 28 bytes for result set at 0x8180ea8 Jun 10 10:01:37 [4378] DBG:db_mysql:db_mysql_get_columns: 1 columns returned from the query Jun 10 10:01:37 [4378] DBG:core:db_allocate_columns: allocate 4 bytes for result names at 0x8180ed0 Jun 10 10:01:37 [4378] DBG:core:db_allocate_columns: allocate 4 bytes for result types at 0x8180ee0 Jun 10 10:01:37 [4378] DBG:db_mysql:db_mysql_get_columns: allocate 8 bytes for RES_NAMES[0] at 0x8180ef0 Jun 10 10:01:37 [4378] DBG:db_mysql:db_mysql_get_columns: RES_NAMES(0x8180ef0)[0]=[concat('',count(1))] Jun 10 10:01:37 [4378] DBG:db_mysql:db_mysql_get_columns: use DB_STRING result type Jun 10 10:01:37 [4378] DBG:core:db_allocate_rows: allocate 8 bytes for rows at 0x8180f00 Jun 10 10:01:37 [4378] DBG:core:db_allocate_row: allocate 20 bytes for row values at 0x8180f10 Jun 10 10:01:37 [4378] DBG:core:db_str2val: converting STRING [0] Jun 10 10:01:37 [4378] DBG:avpops:db_query_avp: rows [1] Jun 10 10:01:37 [4378] DBG:avpops:db_query_avp: row [0] Jun 10 10:01:37 [4378] DBG:avpops:db_close_query: close avp query Jun 10 10:01:37 [4378] DBG:core:db_free_columns: freeing 1 columns Jun 10 10:01:37 [4378] DBG:core:db_free_columns: freeing RES_NAMES[0] at 0x8180ef0 Jun 10 10:01:37 [4378] DBG:core:db_free_columns: freeing result names at 0x8180ed0 Jun 10 10:01:37 [4378] DBG:core:db_free_columns: freeing result types at 0x8180ee0 Jun 10 10:01:37 [4378] DBG:core:db_free_rows: freeing 1 rows Jun 10 10:01:37 [4378] DBG:core:db_free_row: freeing row values at 0x8180f10 Jun 10 10:01:37 [4378] DBG:core:db_free_rows: freeing rows at 0x8180f00 Jun 10 10:01:37 [4378] DBG:core:db_free_result: freeing result set at 0x8180ea8 Before AVP_PRINT Jun 10 10:01:37 [4378] INFO:avpops:ops_print_avp: p=0xb5d3ef08, flags=0x0003 Jun 10 10:01:37 [4378] INFO:avpops:ops_print_avp:                       name=<105> Jun 10 10:01:37 [4378] INFO:avpops:ops_print_avp:                       val_str=<0 / 1> After AVP_PRINT Jun 10 10:01:37 [4378] DBG:avpops:ops_check_avp: check <0> against <0> as str /16777217 The avp value is there now! Why is it happening? Am I doing something wrong? I think the answer is a perfect 'yes'. Thanks for any advice.
