Hello,

the issue is that the sqlops connections are opened in child_init callback which is executed after the event_route[htable:mod-init].

I kind of need same feature for some config, the plan is to add another event_route executed by the sqlops after initialization of its connections.

One workaround for now is to use a shared variable in order to execute that piece of config only once:

if($sht(once)==0) {
    $sht(once) = 1;
    # ... your one time config actions here
}

To be fully safe, if that matters for you at the expense of synchronized execution of that config part, you should wrap the test and update of the $sht(once) inside locks -- see cfgutils module for that.

Cheers,
Daniel

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?
