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?

View 1 RepliesI think this is a really simple question to answer but I can't find a better solution. Basically I am importing data from an external source and as I go through importing each for I am doing a for loop to see if the row already exists; this is taking a life time and I feel it is a very simple way of doing it. Is there a better way to see if a row already exists using specific columns and key indexes?

I have a website that i've been working on for about a year now.Recently, it's started throwing System.AccessViolationException every now and then, in my dev machine, mostly, when I was away from the machine.I haven't changed anything on the server code in weeks, since I've been working 100% on the Javascript part, and this error started appearing recently.
Also, the code I'm doing is 100% managed. I'm not doing any interop, calling strange DLLs, nothing. It's pure VB.Net, so I don't see how I could be generating one of these myself.Now, I've been using this new machine for a couple of months, and it's not working 100% right. Every 2 or 3 days I'm getting a blue screen for example. I haven't had time to diagnose it properly, but I'm suspecting I may have a faulty RAM chip.
