Hello Everyone, I Have I have 4 queries connected to 1 node-red-contrib-stackhero-mysql , The queries is executed at the same time with an inject node , my question is how can i join them and make sure that i received the data of the 4 queries?
I don't have the stackhero mysql node but it may work in the same way as the more familiar node-red-node-mysql.
Set msg.tag on each query before feeding them to SQL.
This value is preserved through the SQL node so you can use it to join the 4 outputs into a single combined message.
