Not sure if what I'm looking to do is missing a small piece of syntax or is unsupported. Say I have a database connection where the connect string property is
jdbc:mysql://localhost:3306/test
If I have that stored to an environment variable $MY_VAR (which I can correctly print in Ignition context and get the same jdbc:mysql://localhost:3306/test returned), what would I have to put in the DB connect string information to get it to expand the environment variable and process the value as the connection? Right now everything I have tried simply processes as a string literal of whatever variation of $MY_VAR and tells me there is no appropriate driver type
