Two connections to the same database

Rails
1

Hi,

I want to let the users of my web app enter plain SQL commands (for
customized reports), so, I want them to do this under a read only mysql
user so that I ensure they won’t compromise any data. But the rest of
the
application needs full r/w access.

So, how can I implement on the same app a second connection just for a
controller for example???

Thanks.

Rather than try to use two connections, why not just scrub their
incoming SQL commands for stuff like INSERT, DELETE, and UPDATE?

Better yet, build a more full-featured query designer so you have
absolute control over what they can and cannot do. Letting random users
execute SQL is pretty dangerous.
