Chapter 1: How to copy table from one database to another in MySQL?

Scenario: I'm trying to build a Jenkins pipeline. According to the requirement, the pipeline should take backup the content from a database and restore it to the new mysql database running on Kubernetes.

Problem statement

When I have tried to restore the dump to new mysql server. It was creating a database which was backed up during the dump process. In a moment, I realised that my application is trying to hit another database for the content. In this case, I left with two options:

• Update the code of the application
• Create a database required by application and copy all the tables from one database to another.
