## 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.

## Troubleshooting

### Error "Connections using insecure transport are prohibited while --require_secure_transport=ON"

You have to connect using TLS encryption. Simply check the box in this node configuration.

### Error "ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client"

You are probably using another node than `node-red-contrib-stackhero-mysql` and tryin to connect to a MySQL >= 8 server using "Caching SHA2 password" authentication method.

To resolve that issue, simply use this node `node-red-contrib-stackhero-mysql`.
