In response to something I heard last night at the NY CFUG meeting about Blue Dragon, I set off to figure out how I one could test to see if a SQL value was NULL or if it was actually an empty string. As it turns out, Mark Mandel had solved this problem months ago in the same fashion (with arguably more elegance). At first I was bummed that I had "reinvented the wheele". Then I was double-bummed to find out that not only had Mark already figured this out but that I had in fact commented on his post back in September (clearly demonstrating to myself that I was not fully aware of what he was talking about).
But then, I realized, if Mark Mandel did it... and then I did it... I MUST be on the right track! So from now on, instead of looking down on reinventing the wheel, I am going to look at it as a litmus test that I am getting smarter :)
