Question New to MySQL, need some help

Hi there,

I'm very new to MySQL and don't know all the signs and symbols. I looked at the mysql.com, but they don't seem to have what I want...

does anybody know a good site to go for a complete list of signs and symbols?

I can't find anything on "@@" sign.
Well I would greatly appreciate it if someone could tell me what "@@" means.

Thanks so much.

In Microsoft SQL Server, perhaps.
I think Rudy was alluding to the fact that this is not in mySQL.

marjon is it possible that @@ is not MySQL? The @@ symbols are used by Ruby to establish class variables
