To select a database in MySQL, you can use the USE statement. This statement allows you to specify which database you want to work with. Here's how you can do it:

Connect to the MySQL server: Open a command-line interface or a terminal and enter the following command, replacing <username> and <password> with your MySQL username and password:

Syntax:

                
    mysql -u <username> -p
                
            

Once you are connected to the MySQL server, you will see a prompt where you can enter commands.

Select a database: To select a database, use the USE statement followed by the name of the database you want to select. For example, to select a database named "mydatabase", you can use the following command:

Syntax:

                
    CREATE DATABASE mydatabase;
                
            

Verify the selection: You can use the SELECT DATABASE(); command to verify that you have successfully selected the desired database. It will return the name of the currently selected database.

That's it! You have now selected the desired database in MySQL. Any subsequent SQL statements you run will be executed within the selected database.

Here's an example of the entire process:

After selecting the database, We can perform any kind of operation on that particular database like create, rename, update, drop table etc.

Note: Make sure the database you want to select exists on the MySQL server. If you try to select a non-existent database, you will receive an error message.
