Hello,

I´m using Kamalio 3.1.0 and want to alter some databases (mysql) tables at kamailio starts. I read that the route event_route[htable:mod-init] allows me to do that, but i´m having some problems.

I load htable.so module and insert the event_route[] in mi kamailio.conf script but when I start kamailio it returns an error:

My event_rout[] is as fallows:

event_route[htable:mod-init]{

sql_query("cd", "select prefix from lcr_rule", "rc");

       xlog("L_INFO", "dbr = $dbr(rc=>rows)");

       if($dbr(rc=>rows)>0){

             $var(i) = 0;

             while($var(i)<$dbr(rc=>rows)){

$var(prefijo)=$dbr(rc=>[$var(i),0]);

xlog("L_INFO", "$dbr(rc=>[$var(i),0])");

                    sql_query("cd", "ALTER TABLE rebalse ADD COLUMN Prefijo_$var(prefijo) INT","rr");

                    $var(i) = $var(i) + 1;

             }

       }

       sql_result_free("rc");

}

I tested the commands inside the event_route[] and they work fine…

Can someone help me?
