No, that is no database. That is a database export file!

That wouldn't work.

You have to create a Database in mysql first (e.g. use phpmyadmin for this)
After that import your sql file into that database (you can do this with phpmyadmin too)

If you have created a database and imported your database data, you use the name of the database to connect your database (simple as it is)

what exactly do you mean by this:

i placed it in mysql folder

I'm unaware of a concept of 'placing' a database in MySQL. I am aware of 'creating' a database with SQL statements either programmatically (phpMyAdmin included) or by using the mysql.exe CLI. The MySQL database manager and its configuration files determine where a database instance's datafiles are located.

How did you create this database, and can you see it in the database table on the left when you start phpMyAdmin?

Good Luck
