[SR-Users] Kamailio 4.2.3 generates core dump when using sql_xquery in event_route htable:mod-init

[Daniel-Constantin Mierla]

Hello,

at that moment the sqlops module is not initialized. The master branch
introduced a new event_route that would be suitable for that.

The htable module is able to load records from a database table in
memory, you just need to have a structure like htable table -- if you
need to pull records from another tables structure, then you can make a
view to look like htable.

Another alternative would be to load via timer or rtimer modules, with a
custom process that runs on timer and first time it executes it will
load records (a $var(...) can be used to know if data was loaded or not).

Anyhow, would be good to get the backtrace from the core dump you got to
know why was crashing -- it should just have thrown errors...

Cheers,
Daniel
