# One database enough?

 * Forgive me if this is a dumb question to most, but I’m coming on over to WP from
   MT and I’m still running MT at my site. So when I upload the ‘wordpress’ folder
   to my html directory and run the “[http://crowndozen.com/wordpress/wp-admin/install.php&#8221](http://crowndozen.com/wordpress/wp-admin/install.php&#8221);
   address in Safari, I get the dreaded ‘error establishing a database connection’
   page, but I’m 99.999% sure all the info is correct. SO, here’s the stupid question:
   I’m new to PHP and WP, but I’ve been using MT and so now if I want to install
   WP while still using MT, do I have to build (buy & install) a second database?

 * hehehehe…. no. You can use just one.
    Check your wp-config.php file, make sure
   the db connection information is correct. And also make sure the file is in the
   main wp install folder. TG

    Well, yeah, the wp-config.php file is in
   the wordpress foler in the html folder of my ftp server. I just renamed it. Was
   I supposed to duplicate it and leave the one with ‘sample’ in it there? Otherwise
   my config info is: // ** MySQL settings ** // define(‘DB_NAME’, ‘crowndozen_com_-
   _db’); // The name of the database define(‘DB_USER’, ‘shanebryant’); // Your 
   MySQL username define(‘DB_PASSWORD’, ‘thepasswordiuse’); // …and password define(‘
   DB_HOST’, ‘localhost’); // 99% chance you won’t need to change this value Is 
   there anything else that could be causing the issue? I feel like it’ sbecause
   I don’t have the CONTENTS of the folder uploaded intot he main directory, but
   I want to keep them in a seperate foler while I install.test/design it, ya know?

 * This is just a shot in the dark, but can a DB name contain underscores and hyphens?
   
   Also, I’m pretty sure if you’re using a database that has other stuff in it, 
   you’ll need to specify the table prefix elsewhere. This is true if you do two
   WP installs on one database, so I assume it’s true if you’re running MT and WP.

    DB names can certainly have underscores (mine does). Not sure about
   hyphens.

 * Hypens are fine too – mine have underscores and hyphens.

 * You say you don’t have the ‘Contents’ of the folder also uploaded ?
    I would 
   imagine that install.php looks for the config information, then also involves
   other files – maybe it needs one that isn’t there ? And is your database actually
   called ‘db’ ? I’ve always been prompted for a name – unless you actually chose‘
   db’ ?
