Ok, here is my scenario. I am querying two separate data sources in Grafana 7.1.x. In both datasources I am querying a table with a column where the entries can match (like key fields in a single database). What I want to do is display the results from query A ONLY if the key value does NOT also appear in query B. In other words, use query B to exclude results from query A in the table. I tried messing with transforms but I couldn't make it work.
