In this blog post, we will explore how to restore a database using the SQL Command Line Interface (CLI). The SQL CLI provides a powerful way to interact with databases and perform various database operations. Restoring a database is a common task that may arise when you need to recover a previous state of your database or migrate it to a new server.

Prerequisites
Before we begin, make sure you have the following prerequisites in place:
- SQL CLI installed on your system.
- Access to the backup file of the database you want to restore.
Backing up the database
To restore a database, you first need to have a backup file of the database that you want to restore. If you don’t have a backup file, you can create one using the SQL CLI with the mysqldump command. Here’s an example of how to create a backup using the mysqldump command:
mysqldump -u [username] -p [database_name] > [backup_file.sql]
Replace [username] with your MySQL username, [database_name] with the name of the database you want to backup, and [backup_file.sql] with the desired name of the backup file.
Restoring the database
Once you have a backup file of the database, you can restore it using the SQL CLI with the mysql command. Here’s an example of how to restore a database:
mysql -u [username] -p [database_name] < [backup_file.sql]
Replace [username] with your MySQL username, [database_name] with the name of the database you want to restore, and [backup_file.sql] with the name of the backup file you want to restore from.
After executing the above command, the SQL CLI will restore the database from the backup file, and you should see the database restored successfully.
Conclusion
Restoring a database using the SQL CLI is a straightforward process. By following the steps mentioned in this blog post, you can easily restore your database from a backup file. Remember to always have a backup of your database in case of any data loss or system failures.
