This document provides steps to connect a Mule ESB flow to a MySQL database: 1) Create a database called "mule_test" and a table called "User" in a MySQL instance. 2) Populate the "User" table with sample data. 3) Create a Mule project with a flow called "db_testFlow" that contains a HTTP listener endpoint. 4) Add the MySQL JDBC driver and configure the database connector. 5) Create a database query in the flow to retrieve data from the "User" table and log the results.

1. Mule ESB
How to connect to a MySql Database

2. Let’s assume you have a fully configured MySql instance in local environment, and you can
access to phpmyadmin administration tool.
As a first step, we begin creating a new Database called mule_test:
Click on create and go to next page

3. Now let’s create a table named User, and populate it as follows with some sample data:

4. It’s time now to populate the table with some data:

5. Let’s dive now in Anypoint Studio and create a new Mule Project, with an empty flow
Called db_testFlow
Let’s configure an http inbound endpoint on localhost:8081/dbTest:
Now we can insert the db component that will get the users inserted in
previous page.
But first of all we have to add the mysql jar client on the buildpath of the
project:

6. Now we can create the connector configuration

7. Finally we can create the query that get the results printing them on the console
with the logger component:
[[db_test].HTTP_Listener_Configuration.worker.0
