A Node-RED node to read and write to a MySQL database.
Run the following command in your Node-RED user directory - typically ~/.node-red
npm install node-red-node-mysql
Allows basic access to a MySQL database.
This node uses the query operation against the configured database. This does allow both INSERTS and DELETES.
By it's very nature it allows SQL injection... so be careful out there...
The msg.topic must hold the query for the database, and the result is returned in msg.payload.
Typically the returned payload will be an array of the result rows.
If nothing is found for the key then null is returned.
The reconnect retry timeout in milliseconds can be changed by adding a line to settings.js
mysqlReconnectTime: 30000,
