MySQL DROP DATABASE: Delete Database

The DROP DATABASE statement in MySQL is used to delete an existing database in MySQL, including all of its tables and data.

Important: Be careful with the DROP DATABASE statement. Once the database is deleted, you cannot retrieve it.

Prerequisites:

A MySQL server up and running.
Access to a MySQL user account with privileges to drop databases.

Tutorial:

Connect to the MySQL server:

To start the mysql command-line client, open your terminal or command prompt, and enter:

mysql -u [username] -p

Replace [username] with your MySQL username and enter your password when prompted.

Using the DROP DATABASE statement:

The basic syntax for using the DROP DATABASE statement is as follows:

DROP DATABASE database_name;

Replace database_name with the name of the database you want to delete.

For example, to delete a database named mydb, you would use:

DROP DATABASE mydb;

This will delete the database named mydb along with all of its tables and data.

Exit the MySQL command-line client:

EXIT;

By using the DROP DATABASE statement in MySQL, you can easily delete databases. This can be useful when you want to clean up unused databases, but always be sure you want to permanently delete the database before using this command.

Dropping a MySQL Database with DROP DATABASE:
- Syntax:
```
DROP DATABASE database_name;
```
- Example:
```
DROP DATABASE mydatabase;
```
Dropping Multiple Databases in a Single MySQL Statement:
- It's possible to drop multiple databases in a single statement.
- Example:
```
DROP DATABASE db1, db2, db3;
```
Preventing Accidental Deletion with MySQL DROP DATABASE:
- Use conditional checks or confirmations to prevent accidental deletion.
- Example:
```
DROP DATABASE IF EXISTS mydatabase;
```
Dropping Databases with Specific Character Sets in MySQL:
- Specify the character set and collation when dropping a database.
- Example:
```
DROP DATABASE mydatabase CHARACTER SET utf8 COLLATE utf8_general_ci;
```
