Hi list

i'm config SQLOps Module with postgresql db module or is postgresql driver?

this is my kamailio config:

#!ifndef DBURL
#!define DBURL "postgres://user:ouser@x.x.x.x/kamailio"
#!endif

sql_query("ca", "select * from xxxxx","ra");

if($dbr(ra=>rows)> 0){
xlog("L_INFO", "saldo:$dbr(ra=>[0,0]) y seg:$dbr(ra=>[0,1]) ");

$var(credit) = $dbr(ra=>[0,0]); # 30$ of credit
$var(cost_per_sec) = $dbr(ra=>[0,1]); # 1$ per sec
$var(i_pulse) = "1"; # 1$ to establish the call
$var(f_pulse) = "1"; # 1$ per second

sql_result_free ("ra");

if($var(cost_per_sec) > $var(credit)) {
                sl_send_reply("402","payment required");
                exit;
        }

}

i got this warning and would like why this happen:

WARNING: db_postgres [km_dbase.c:235]: db_postgres_submit_query(): postgres result check failed with code 7 (PGRES_FATAL_ERROR)
