I agree. I had this in mind.

I see that most of the times the solutions given in the forums are not consumed entirely in its original form. People take ideas from it and convert it to a form that suites their specific business requirements.

Similarly, when people post problems on the forums, they may not be posting the actual problem, but a subset of the specific problem. If they manage to get that solved, they could customize it to their specific requirement and add the additional validations and processing etc.

ROW_NUMBER() is a great function and it can be used to solve a number of issues. My previous post attempts to solve the problem described in this post using ROW_NUMBER() with the given details of the problem. But it does not mean that ROW_NUMBER() is the right approach, because the post still does not provide the additional details of the application and specific business line.
