If you are looking for powerful managed services, like Node-RED, MySQL or MariaDB, you should seriously consider Stackhero
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 thepayload
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.
