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.

what don't you understand? I do not know what to explain. Is there any error you get? At least the parameter key_value is wrong, should be key_value_column.

Cheers,
Daniel
Thanks All,

Alex

Thank you Daniel,

I will try first oracle db and then htable which is also very interesting. When I'm done I will get back with the results.

Hi all,

Concerning portability again :-)

Is there any way I can add in the memory all the numbers with portability? (2.000.000 rows)?
And also reload these data a few times a day and access this data from the Kamailio script?

while I advise usage of sqlops/sql_query() instead of avpops/avp_db_query(), if you want to load such data in memory should be in shared memory. For that look at htable or maybe you can re-use pdt.

There are the $var PVs you already mentioned, and then also the $shv that
are shared variables. But they are (process) global, and not
transactional. Daniel proposed and developed the new xavp type for sr
which are basically extended AVPs. More informations can be found here:

`key_name_column: here I understand that is the name of the key = fist col (phonenumber)`

`key_type_column == string ?`

`value_type_column == string ?`

`key_value_column == second col(prefix)?`
