Create a MySQL database with charset UTF-8

Question

I'm new to MySQL and I would like to know:

How can I create a database with charset utf-8 like I did in navicat?

create mydatabase;

...seems to be using some kind of default charset.

Answer 1

Update in 2019-10-29
As mentions by @Manuel Jordan in comments, utf8mb4_0900_ai_ci is the new default in MySQL 8.0, so the following is now again a better practice:

CREATE DATABASE mydatabase CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci;

Answer before 2019-10-29
Note: The following is now considered a better practice (see bikeman868's answer):

CREATE DATABASE mydatabase CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Original answer:

Try this:

CREATE DATABASE mydatabase CHARACTER SET utf8 COLLATE utf8_general_ci;

For more information, see Database Character Set and Collation in the MySQL Reference Manual.

Answer 2

You should use:

CREATE DATABASE mydb CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Note that utf8_general_ci is no longer recommended best practice. See the related Q & A:

What's the difference between utf8_general_ci and utf8_unicode_ci on Stack Overflow.
