   connecting to psysical database...

Answer 1

Log in to the mysql server,

$ mysql -u <username> -p<password>

List all the databases,

mysql> show databases;

Check whether your DB name is there,

+--------------------+
| Database           |
+--------------------+
| information_schema |
| kholofelodb        |
| mysql              |
| phpmyadmin         |
+--------------------+

Please note: database names are case sensitive.

Hope this helps.

Answer 2

It seems that the fault lies with the name of your database. MySQL is the database engine, but within MySQL you can have a number of databases with their own tables. Once you get the database name correct, you may find that the problem will resolve.

Answer 3

yeah this case arrived to me also and actually my database name was correct but the problem is in my port number I was using WAMPP server whose port number is 3308 and i wasted my time by using 3306 so u can check that are u using any other app then first it is recommended to check the port value of it...........

Answer 4

please check in mysql database whether the database name 'kholofedb' is existed or not

i think you haven't created

please check it once if no create it and its related tables also

Answer 5

I had the same issue and found that the cause of it was: The name of the database here is CASE SENSITIVE! So, I was trying to connect using a database name like "test2", but the database name actually was "Test2".

Answer 6

Issue is with your database names only. First create on database in mysql* create database connection .Concentrate on these areas : database name : URL: mention database name properly that database name should be reflects database in mysql*
