ERROR: db_mysql [km_dbase.c:128]: db_mysql_submit_query(): driver error on query: Unknown column '8d77' in 'where clause' (1054)
Aug  7 18:09:22 localhost /usr/local/sbin/kamailio[25333]: ERROR: <core> [db_query.c:181]: db_do_raw_query(): error while submitting query

I'm getting the above error message when, variable front_id=8d77 is alphanumeric.

It's working fine when front_id is pure numeric. eg: front_id=877 

Database column front_id is VARCHAR(255).

Any suggestions to solve this error?

Thanks,

Arish
