MySQL: Cloning a MySQL database on the same MySql instance

Cloning a MySQL Database on the Same MySQL Instance

👋 Hey there, tech enthusiasts! Are you searching for a quick and hassle-free method to clone a MySQL database on the same MySQL instance? Look no further because we've got you covered! In this blog post, we will address the common issue of cloning a database and provide you with easy solutions that will save you time and effort. 💪

The Problem: Dumping and Importing a Database

So, you want to clone a MySQL database, let's say from sitedb1 to sitedb2. One way to achieve this is by using the mysqldump command to dump sitedb1 to an SQL file. Here's an example command:

mysqldump -u root -p sitedb1 > ~/db_name.sql

Once you have the SQL file, you can import it into sitedb2 using the MySQL command line or a GUI tool. Easy, right? But what if we told you there's an even easier way? 😏

The Solution: The CREATE DATABASE and CREATE TABLE AS SELECT Statements

Yes, you heard it correctly! We can avoid the hassle of dumping and importing a database by using the power of MySQL statements. The two statements we'll be using are CREATE DATABASE and CREATE TABLE AS SELECT. Let's see how it works!

Step 1: Create a New Database

To get started, we need to create a new database sitedb2 using the CREATE DATABASE statement. Here's an example query:

CREATE DATABASE sitedb2;

Step 2: Clone the Tables

Next, we need to clone the tables from sitedb1 to sitedb2. We can achieve this using the CREATE TABLE AS SELECT statement. This statement creates a new table with the same structure and data as the source table. Take a look at this example:

CREATE TABLE sitedb2.table_name AS SELECT * FROM sitedb1.table_name;

Repeat this step for each table you want to clone. 💡 Remember to replace table_name with the actual name of each table.

Step 3: Done!

That's it! 🎉 You have successfully cloned your MySQL database without the need for dumping it to an SQL file. With just a few simple SQL statements, you have saved precious time and avoided unnecessary steps.
