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?
