What if we want to get the last row of data in a table? Check out the answer in the video TSQL: Get Last Row of Data In A Table. As you can see, we get the final row of data in our example table by using one approach to get this information.
Two key points about this:
- What is one clarification you would want to know?
- What should we look at prior to finding the last row?

In this table, we have a data set that is organized by date. This ultimately makes it easy and we observe that there are many ways to get this information. For an example, we could easily select the row by the most recent date (the final row). Ultimately, there is an order to the data, if we need to select the last row of data in a table. We should find what that order is and select from there.
One regular point I like to remind my audience, especially as of recent: we can often solve the same problem with a variety of techniques. While we look at one or two ways to solve the problem, these aren't the only ways we can approach this problem. The most appropriate solution to a problem is one in which you can troubleshoot quickly in the future and one in which you understand. Be careful about applying solutions that solve a problem, but introduce new problems in the future.

A great re-occuring example of this is my discussion on alerting best practices. There are a variety of alerts everywhere for everything in today's development environments, but many of these alerts cause more issues than they solve (one of which is creating a distraction). Be careful about "easy" solutions which introduce bigger problems. Know your environment and where to apply the best solution. Of course, all these being written, it is helpful to learn new techniques to solve problems because they may be useful in the future.
