    Question Unanswered: 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 my opinion, @@is used when you want to use the system variables in you SQL

    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
