I think I know why the crash happens. And it's easy to "workaround". However, I'm not sure what would be the proper fix for this. It seems that sqlite does not support reporting the column type for computed fields. This implies that the db_sqlite driver cannot deduce the proper return value type either (I will likely just hard code it to INT now). However, this means that other kind of expressions - e.g. string manipulations - will not work then. I guess we should first try decltype if available and fall back to first row column type. However, this will fail too if the first row has NULL value for the column. The fundamental problem is that Kamailio DB API expects the driver to return stored type - which on sqlite is not fixed. Will try to get something sketched up soonish. -Timo _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
