[Freeswitch-users] mod_lcr for a-z rates

[Diego Viola]

Hi everyone,

I have used freeswitch/scripts/contrib/intralanman/C/lcr/sql/mysql-5.0.sql
to load the mod_lcr schema, that worked well.

But whenever I try to insert data from the "Sample Data" in the wiki it
fails: http://wiki.freeswitch.org/wiki/Mod_lcr#Sample_Data

mysql> INSERT INTO lcr (digits, rate, carrier_id, lead_strip, trail_strip,
    ->                  prefix, suffix,
    ->                  date_start, date_end, quality, reliability) VALUES
    ->        ('1', 0.15, 1, 0, 0, '', '',
    ->         current_timestamp - interval 1 year,
    ->         current_timestamp + interval 1 year
    ->         , 0, 0);
ERROR 1452 (23000): Cannot add or update a child row: a foreign key
constraint fails (`fs_lcr/lcr`, CONSTRAINT `carrier_id` FOREIGN KEY
(`carrier_id`) REFERENCES `carriers` (`id`) ON DELETE CASCADE ON UPDATE
CASCADE)
mysql>

Regards,

Diego
