Daniel,<br><br>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 :-(<br>

Hi Alex,<br>
<br>
the default table structure for htable is defined by sql:<br>
<br>
CREATE TABLE htable (<br>
id INT(10) UNSIGNED AUTO_INCREMENT PRIMARY KEY NOT NULL,<br>
key_name VARCHAR(64) DEFAULT '' NOT NULL,<br>
key_type INT DEFAULT 0 NOT NULL,<br>
value_type INT DEFAULT 0 NOT NULL,<br>
key_value VARCHAR(128) DEFAULT '' NOT NULL<br>
) ENGINE=MyISAM;<br>
<br>
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:<br>

My problem is how to define the hash table in Kamailio.cfg. Especially
I don't understand how to define :<br>
<h3><code>key_name_column: here I
understand that is the name of the key = fist col (phonenumber)<br>
</code></h3>
<h3><code>key_type_column == string ?<br>
</code></h3>
<h3><code>value_type_column == string ?<br>
</code></h3>
<h3><code>key_value_column == second
col(prefix)?<br>
</code></h3>
<br>
<br>
I get the following errors:<br>
<br>
ERROR:db_mysql:db_mysql_submit_query: driver error on query: Unknown
column 'key_type' in 'field list'<br>

I'm giving some parameters but some of them i don't really understand

<br>
# --------- Htable ---------<br>
modparam("htable", "htable", "a=>dbtable=ported1;")<br>
modparam("htable", "db_url",
"mysql://pskoul:pskoul123@localhost/openser")<br>

modparam("htable", "key_value", "prefix")<br>
modparam("htable", "fetch_rows", 1000)<br>
<br>
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.<br>

<br>
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.<br>

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.<br>

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

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.<br>

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