MySQL restore database (mysql command)

This tutorial will guide you through the process of restoring a MySQL database using the mysql command-line client. It assumes you have a SQL dump file generated by the mysqldump utility or another tool that exports data in SQL format.

Prerequisites:

A MySQL server up and running
Access to a MySQL user account with privileges to create and modify tables
A SQL dump file (e.g., backup_file.sql)

Tutorial:

Create an empty database (optional):

Before restoring the database, you may want to create a new, empty database to import the data into. Connect to the MySQL server using the mysql command:

mysql -u [username] -p

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

Create a new database with the appropriate name and character set:

CREATE DATABASE [new_database_name] CHARACTER SET [character_set] COLLATE [collation];

Replace [new_database_name], [character_set], and [collation] with the appropriate values. For example:

CREATE DATABASE restored_db CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

Exit the MySQL command line:

EXIT;

Restore the database from the SQL dump file:

To restore the database from the backup file, run the following command:

mysql -u [username] -p [database_name] < [backup_file.sql]

Replace [username], [database_name], and [backup_file.sql] with the appropriate values. For example:

mysql -u root -p restored_db < /backups/my_database_backup.sql

You'll be prompted to enter the password for the MySQL user.

Once the restoration process is complete, your new database will contain the same structure and data as the original database at the time of the backup.

Note: If your SQL dump file contains a CREATE DATABASE statement, you can skip step 1. However, be aware that the mysql command will create the database with the same name and character set specified in the dump file. To use a different name or character set, follow step 1 to create the database manually and then proceed with step 2 to import the data.
