CREATE DATABASE

Syntax

The syntax of creating a database in SQL is as follows:

CREATE DATABASE database_name;

Here, database_name refers to the name of the database that you want to create.

Example

Let's say you want to create a database named mydb. The SQL query to create this database will be:

CREATE DATABASE mydb;

Output

When you execute the above SQL query, you will receive a success message indicating that the database has been created. You can also use the following command to check if the database has been created or not:

SHOW DATABASES;

This will display a list of all the databases present in your MySQL environment, and you should be able to see the mydb database in the list if it has been created successfully.

Explanation

Creating a database is a basic operation in MySQL. The CREATE DATABASE query is used to create a new database in the MySQL environment. You can then use this database to store tables and other objects that you need for your application.

Use

The CREATE DATABASE operation is commonly used when you are building a new application and need a dedicated database to store its data. You can also use this operation if you want to create a backup database or if you want to test new software in a fresh environment.

Important Points

• The CREATE DATABASE operation requires admin privileges in MySQL.
• Make sure that the name of the database you're creating is unique and doesn't conflict with any other databases present in the MySQL environment.
• You cannot use certain special characters in the database name. MySQL supports only alphanumeric characters and underscores in the database name.

Summary

In this section, we discussed the CREATE DATABASE operation in MySQL. You learned about its syntax, example, output, explanation, use cases, important points, and summary. This operation is a fundamental operation in MySQL that you will use frequently when building new applications or working with databases.
