Hello,

What will be the best way to save ISP Information in Kamailio memory?

I have the following information for each ISP into the DB:

ISP1          |  1.1.1.1 | user                  | pass                 | 1234

This info it's not changed/updated too often, so I want to avoid querying the DB on every call and get this info directly from the memory.

I was thinking to use htable for that, so I created a htable as an array for that and loaded all the information there manually, something like that:

$sht( isp => ISP1[prefix]) == "1234"

So far so good, I'm able to get this information from the htable and use it whenever I need it.

Now, the problem comes when I want to load all this information automatically from the DB. How can I setup htable module to get the array key (address, username...) from the database automatically on server restart, and append this array_key to the column value?

I've tried this way:

But it's not working unfortunately, getting back this error: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '[address]'

If I'm setting this way:

and setting trunk_name value to: ISP1[address], then it's working fine, but in this case I will have to create by one column for each array key, which may be confusing and it's a lot of unnecessarily information into the DB.

Is it possible to do that, or better to trigger a script on each restart which will load this information from the DB into htable?

Thanks
