Hi guys... I'm quite new to SQL and online DB... Actually zero experience... But I have an Idea to an app wich will get 90% of on screen info from an online DB... My issue is.... comments. I imagine my app having only one or two tables... I think... I will have to work those out after... when I used Access DBS there was a "Key" field wich could be used across all tables of the DB... is it possible to do it with SQL too? My main table will contain location info, but I want to link a "user comments" table by a "common" field like a key field... Hmmmm am I making any sense here?
