无法连接到mysql数据库[phpmyadmin]

Question

• to create databases I'm using xampp->phpyadmin,
• I have created a database called "dungeons",

• in my php code Im connecting to MySQL with this code:

   if ($_SERVER["SERVER_ADDR"]=="localhost") { define("SQL_HOST","localhost"); define("SQL_DBNAME","dungeons"); define("SQL_USERNAME",xxx); define("SQL_PASSWORD",xxx); } else { define("SQL_HOST","127.0.0.1"); define("SQL_DBNAME","dungeons"); define("SQL_USERNAME", xxx); define("SQL_PASSWORD",xxx); } mysql_connect(SQL_HOST, SQL_USERNAME, SQL_PASSWORD) or die("Cannot connect to mySQL: " . mysql_error()); mysql_select_db(SQL_DBNAME) or die("Cannot connect to the database: ". mysql_error()); 

The error message says

Unknown database 'dungeons', when selecting db.

I don't have any idea where the problem is, since the database is made and I have successfully connected to the mysql with the code.

Answer 1

The error is correctly saying that the database is not available or not there. First create a new database in phpmyadmin and name it dungeons. After that try your script. Thank you

Answer 2

The error message says

Unknown database 'dungeons'

There doesn't exist a database with name "dungeons".

First create a database using

create database dungeons;
