I have a program which is almost complete, it gets data that is new or newly modified (well at least since my program last got this data). The problem I have is currently i'm adding this "new" data but i've just clicked some of this data may be in my database already just updated. For example, I have added some user data to my database but a user has just updated their user name - so this is now newly modified! I don't want to add it as new data I want to update my current row in my database. My question is how can i do a SQL query in my access database to see if this row exists or not?

Is there a better way to see if a row already exists using specific columns and key indexes?
