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:

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.
