# node-red-contrib-mysql-config
[Node-RED](https://nodered.org) node to read and write to a MySQL or a MariaDB database.
## Foreword
**Note:** All credit for this work goes to the original creator(s): [https://github.com/stackhero-io/node-red-contrib-stackhero-mysql](https://github.com/stackhero-io/node-red-contrib-stackhero-mysql)
This is a fork for the purpose of configuring a connection using environment variables.
## Use Case
The primary use case for using this version is in instances where NodeRED changes are being deployed using CI/CD pipelines across multiple environments and credentials need to be configured using environment variables as opposed to manually setting them in the NodeRED UI.
## Configuration
In order to configure this node, set each of the inputs with it's environment variable name.
## Usage
This node is really simple.
Put your query in the `topic` variable and, if you have arguments, put them in an object in the `payload` variable.
You will get the result in the `payload` output variable.
Example:
```javascript
msg.topic = 'SELECT * FROM `users` WHERE `name` = :name AND `age` > :age;';
msg.payload = { name: 'Adrien', age: 30 };
return msg;
```
> Avoid SQL injections!!
>
> Do not NEVER EVER put variables content in `topic` directly!
> Always use the `payload` variable to pass your arguments.
