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.
