Re: Connections on Database

You probably only want max_connections and not max_user_connections. Max_user_connections is the number of times a user can connect per hour.. -Eric 2008/3/31 Vidal Garza [EMAIL PROTECTED]: Velen escribió: Hi, How can i limit connections to my database? Regards, Velen

Add an alias for the subquery select * from ( select ) my_alias where dd = 3; Better, use a having clause and eliminate the subquery. Odds are it will be more efficient in MySQL. How to replace the original one with a having statement? Thanks again. Get the name you

Two databases, two disks

Hi All, I have two MySQL databases and I would like to place each one of them on a separated disk, and backup each one of them separately. I understand I need to use the One file per table option, right? It will effect all the databases. How do I place each database on a different volume?
