MySQL CREATE DATABASE: Create A Database

The CREATE DATABASE statement in MySQL is used to create a new database in MySQL.

Prerequisites:

A MySQL server up and running.
Access to a MySQL user account with privileges to create 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 CREATE DATABASE statement:

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

CREATE DATABASE database_name;

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

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

CREATE DATABASE mydb;

This will create a new database named mydb.

Specify the Character Set and Collation:

When creating a database, you can specify the character set and collation by using the CHARACTER SET and COLLATE clauses. For example:

CREATE DATABASE mydb CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

This will create a new database named mydb with a character set of utf8mb4 and a collation of utf8mb4_unicode_ci.

Exit the MySQL command-line client:

EXIT;

By using the CREATE DATABASE statement in MySQL, you can easily create new databases. This can be useful when you want to set up a new project, create a testing environment, or create a separate database for different parts of your application.

Creating a New Database with MySQL CREATE DATABASE:
- Syntax:
```
CREATE DATABASE database_name;
```
- Example:
```
CREATE DATABASE mydatabase;
```
Specifying Character Set and Collation in MySQL CREATE DATABASE:
- Specify the character set and collation for the new database.
- Example:
```
CREATE DATABASE mydatabase
CHARACTER SET utf8
COLLATE utf8_general_ci;
```
Setting Default Options for a Database in MySQL:
- Define default options for the database during creation.
- Example:
```
CREATE DATABASE mydatabase
DEFAULT CHARACTER SET utf8
DEFAULT COLLATE utf8_general_ci;
```
MySQL CREATE DATABASE and Permissions:
- Users must have the necessary privileges to create databases. Grant appropriate permissions.
- Example:
```
GRANT ALL PRIVILEGES ON mydatabase.* TO 'username'@'localhost' IDENTIFIED BY 'password';
```
Checking if a Database Exists Before Creating it in MySQL:
- Use conditional checks to ensure the database doesn't exist before creating.
- Example:
```
CREATE DATABASE IF NOT EXISTS mydatabase;
```
Creating Multiple Databases with a Single MySQL Statement:
- It's possible to create multiple databases in a single statement.
- Example:
```
CREATE DATABASE db1, db2, db3;
```
MySQL CREATE DATABASE and Storage Engine Options:
- Specify the storage engine for the database during creation.
- Example:
```
CREATE DATABASE mydatabase
CHARACTER SET utf8
COLLATE utf8_general_ci
ENGINE = InnoDB;
```
