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;
`
If you have multiple arguments, put them in an array of objects in the payload variable.
You will get the result in the payload output variable.

Example:

`javascript
msg.topic = 'INSERT INTO users (name, age) VALUES( :name, :age) ;';
msg.payload = [
{ name: 'Adrien', age: 30 },
{ name: 'Maria', age: 62 }
]
return msg;
`
> Avoid SQL injections!!
>
> Do not NEVER EVER put variables content in topic directly!
> Always use the payload variable to pass your arguments.
