Could use more info around this:

"CREATE EXTERNAL TABLE prices(   Id int,  product VARCHAR(64),  price int) WITH (   LOCATION = '/',   DATA_SOURCE = prices,   FILE_FORMAT = sqlservercentralformat)"This, "LOCATION = '/', ", doesn't work.  I tried looking it up to see what the location should be and it's pretty cryptic.  I suspect this is a path with the container name, blob name, and file name, but when I put in the name of my folder and the file name, LOCATION = '/polybasetutorial/prices.csv', it doesn't work.
