mysqldump with create database line

I'm in the process of moving my files onto another computer, and one thing I would like to do is to transfer the data in my MySQL database. I want to dump the databases into .sql files, but also have the create database db_name including in the file, that way I just have to import the file to mysql without having to manually create the databases. Is there a way to do that?

By default mysqldump always creates the CREATE DATABASE IF NOT EXISTS db_name; statement at the beginning of the dump file.

[EDIT] Few things about the mysqldump file and it's options:

--all-databases, -A

Dump all tables in all databases. This is the same as using the --databases option and naming all the databases on the command line.

--add-drop-database

Add a DROP DATABASE statement before each CREATE DATABASE statement. This option is typically used in conjunction with the --all-databases or --databases option because no CREATE DATABASE statements are written unless one of those options is specified.

--databases, -B

Dump several databases. Normally, mysqldump treats the first name argument on the command line as a database name and following names as table names. With this option, it treats all name arguments as database names. CREATE DATABASE and USE statements are included in the output before each new database.

--no-create-db, -n

This option suppresses the CREATE DATABASE statements that are otherwise included in the output if the --databases or --all-databases option is given.

Some time ago, there was similar question actually asking about not having such statement on the beginning of the file (for XML file). Link to that question is here.

So to answer your question:

• if you have one database to dump, you should have the --add-drop-database option in your mysqldump statement.
• if you have multiple databases to dump, you should use the option --databases or --all-databases and the CREATE DATABASE syntax will be added automatically

The simplest solution is to use option -B or --databases.Then CREATE database command appears in the output file. For example:

mysqldump -uuser -ppassword -d -B --events --routines --triggers database_example > database_example.sql

Here is a dumpfile's header:

-- MySQL dump 10.13  Distrib 5.5.36-34.2, for Linux (x86_64)
--
-- Host: localhost    Database: database_example
-- ------------------------------------------------------
-- Server version       5.5.36-34.2-log

/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;

/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;

--
-- Current Database: `database_example`
--

CREATE DATABASE /*!32312 IF NOT EXISTS*/ `database_example` /*!40100 DEFAULT CHARACTER SET utf8 */;

Here is how to do dump the database (with just the schema):

mysqldump -u root -p"passwd" --no-data --add-drop-database --databases my_db_name | sed 's#/[*]!40000 DROP DATABASE IF EXISTS my_db_name;#' >my_db_name.sql

If you also want the data, remove the --no-data option.
