A Top N query is one that fetches the top records, ordered by some value, in descending order. Typically, these are accomplished using the TOP or LIMIT clause. Problem is, Top N result sets are limited to the highest values in the table, without any grouping. The GROUP BY clause can help with that, but it is limited to the single top result for each group. If you want the top 5 per category, GROUP BY won't help by itself. That doesn't mean it can't be done. In fact, in today's blog, we'll learn exactly how to construct a Top N query by group.
Deciding whether do create a function in the database or in application code can be a daunting one. All-too-often, you don't realize that you've made the wrong choice until it's a big hassle to make an about-face. Worse still is the fact that many developers base their decision on whether they're most familiar with SQL or application coding! A better approach is to rely on the strengths of a technology to help guide your decision. In today's blog, we'll break down the decision making process when choosing between a user-defined function (UDF) and one that resides on the application side.
