Glad you found it.
There are more and more resources added to workshops.opto22.com all the time.
That video was done by our summer intern Terry. Hes made a few posts to the forums, mostly in the Node-RED category.
I’m also sure you saw the other long thread on this topic in the forums by doing a search on ‘mssql’, there is a lot of information in there as well (including sample flows).
