How can you choose a database in mysql?

In MySQL, you can use the following command to select a database:

1. Utilize the USE command:
2. Switch to the database named database_name.
3. Here, database_name is the name of the database to be selected. This command will change the default database of the current session to the specified database.
4. Use the “USE” command and backticks (`):
5. Connect to the database named `database_name`.
6. If the database name contains special characters or reserved words, you can enclose it using backticks.
7. Use fully qualified table name (database_name.table_name):
8. Retrieve all data from the table named “table_name” in the database named “database_name”.
9. With this syntax, it is possible to directly specify the database and table names to be manipulated in the query statement.

It is important to note that selecting a database only changes the default database of the current session, it does not actually create or delete the database. If the specified database does not exist, selecting that database will fail.
