SQL to Subscribe Users to Channels?

[cmsouth]

I've searched thru the forum and google, but have not found sql that others have posted to update the channel subscriptions of users - is there a location that others have posted sql they have used?

We have an forum for company only users and want to subscribe them to all channels. I had a developer subscribe everyone to threads, but i've learned that you need to subscribe to channels to get new topics. I can't find any doc on the table structure to do a query by trial/ error, so even that would be helpful. Thx
