# Installation problem: Can’t select database

 *  Resolved 814714
 * [17 years, 10 months ago](https://wordpress.org/support/topic/installation-problem-cant-select-database/)
 * I have downloaded WAMP, installed the mysql, php & apache products.
 * I am trying to connect to the DB in order to perform installation. I have edited
   the config file, but WP is unable to select the database. I know it exists, and
   the user has permission, so I guess that leaves the DB NAME? I’ve tried root_wordpress
   as the DB name, no luck.
 * Would appreciate some help with this matter. I’ve installed WP a number of times,
   no problem. This is my first time locally however..
 * ========================
    The error message: ======================== Can’t select
   database
 * We were able to connect to the database server (which means your username and
   password is okay) but not able to select the _wordpress database.
 *  * Are you sure it exists?
    * Does the user root@localhost have permission to
   use the _wordpress database? * On some systems the name of your database is prefixed
   with your username, so it would be like username_wordpress. Could that be the
   problem?

 * What is the actual database name? Use that.
 * Since it connected okay, then the dbhost, username, and password are correct.
   You simply have the database name wrong.
 * “root_wordpress” makes little sense as a database name. Same for “_wordpress”.
   Did you perhaps just name it “wordpress”? You need *only* the database name, 
   not any other stuff thrown in.

 * I have tried using the database name for DB name, the above error message was
   taken when I was experimenting with a variety of DB names, to see if it was a
   unknown convention causing issues.

 * That did it! Thank you very much. In phpmyadmin it has root@localhost as the 
   user, but using just root instead fixed it.
 * Once again, thank you.
