How Can I Clone a MySQL Database on the Same Instance Without a Dump Script?

Cloning a MySQL Database on the Same Instance without a Dump Script

While it's common to create a database copy by dumping and importing an SQL script, there's a more efficient alternative for cloning a MySQL database on the same instance.

Instead of generating a SQL dump, you can seamlessly transfer data directly through MySQL commands. By piping the dump output from mysqldump into the mysql client, you can create a duplicate database with ease:

mysqldump --routines --triggers db_name | mysql new_db_name

This approach ensures a swift and direct database cloning without the need for intermediate SQL scripts.

Additionally, you can customize the cloning process by specifying connection details and configuring additional settings:

mysqldump -u <user name> --password=<pwd> <original db> | mysql -u <user name> -p <new db>

Remember to create the target database (new_db) beforehand if it doesn't exist. By following these steps, you can effortlessly clone a MySQL database on the same instance, leveraging the built-in functionality of the MySQL utilities.
