In this video Opto 22’s Terry Orchard takes a deep dive into the MySQL database nodes to insert data into and select data from a MariaDB server. Terry shows you how two different methods are used to insert: first using locally saved context variables within Node-RED, and then building up similar data in a single message object. Finally we select the data back into the flow and display it in a Node-RED dashboard table that is running on a groov RIO.

Terry uses a groov RIO as a means of gathering physical I/O inputs and outputs. Opto 22’s groov RIO is edge I/O for the IIoT: standalone industrial I/O that collects and securely publishes data from field to cloud. https://www.opto22.com/products/groov-rio
