[Kamailio-Users] avpops OR sqlops

[alex pappas]

Hi all,

It is possible to have some help in defining the hash table?

I'm giving some parameters but some of them i don't really understand them.
my configuration is:

# --------- Htable ---------
modparam("htable", "htable", "a=>dbtable=ported1;")
modparam("htable", "db_url", "mysql://pskoul:pskoul123@localhost/openser")
modparam("htable", "key_name_column", "phonenumber")
modparam("htable", "key_value", "prefix")
modparam("htable", "fetch_rows", 1000)

The table I want to htable is a 2 cols table (phonenumber,prefix) In mysql
they are defined as varchar(10). All the phonenumber values are unique so
the key in htable is phonenumber with value in prefix.

Thanks All,

Alex
