Mysql and mysql2 gem

Rails

Can someone please tell me what the difference is ?

Thanks, RVc

In very simple terms, they both do the same things, but the latter is
newer and better and faster, and compatible with newer versions of Ruby
(and Rails). I think maybe there may be versions of MySQL that are too
new for the mysql gem, too, but that’s just a guess. Unless you are
using Rails 2 under Ruby 1.8.6, I doubt very much that you will need the
mysql gem these days, in favor of mysql2.
