Database Query to Add List Usernames to a Secondary Usergroup

[danielTMC]

Does anyone know a database query that can be used to assign a list of usernames to a given secondary usergroup.

Many thanks in advance.

Don't use SQL as the usergroup bits have a fair bit of complexity.

I'ld recommend using php and calling the standard function as described in this recent thread; https://xenforo.com/community/threads/user-groups-and-php.118730/
