Daniel,
The reason that I was NOT understanding how to implement the htable is that
even I read the all internet ;-) I did not see the already setup table
Htable in my mysql server which was already made from the installation and
that's why the value type and key types did not make sense!! now i fill a
bit stupid :-(
I apologize for stilling you time.
Cheers
Alex

Hi Alex,
the default table structure for htable is defined by sql:
CREATE TABLE htable (
id INT(10) UNSIGNED AUTO_INCREMENT PRIMARY KEY NOT NULL,
key_name VARCHAR(64) DEFAULT '' NOT NULL,
key_type INT DEFAULT 0 NOT NULL,
value_type INT DEFAULT 0 NOT NULL,
key_value VARCHAR(128) DEFAULT '' NOT NULL
) ENGINE=MyISAM;
If you map over another table, then you must have at least four columns
there (id is for generic purpose). See here descriptions of the columns:
http://kamailio.org/docs/modules/3.0.x/modules_k/htable.html#id2529061

Hi Daniel,
My problem is how to define the hash table in Kamailio.cfg. Especially I
don't understand how to define :
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)?
I get the following errors:
ERROR:db_mysql:db_mysql_submit_query: driver error on query: Unknown
column 'key_type' in 'field list'
ERROR:core:db_do_query: error while submitting query
ERROR:htable:ht_db_load_table: Error while querying db
ERROR:core:init_mod: failed to initialize module htable
ERROR:core:main: error while initializing modules
Thank you
Alex

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.
Cheers
