SQL Tips and Tricks: How to Efficiently Calculate Running Total in Your Queries | EssentialSQL

In this video tutorial, we will show you how to calculate a running total in SQL using a window function. A window function is a powerful tool in SQL that allows you to perform calculations across a set of rows that are related to the current row. By using the window function to calculate the running total, you can simplify your SQL code and improve the performance of your queries. We will walk you through the steps to write a SQL query that uses the window function to calculate a running total, and show you some examples of how to apply it to different scenarios. By the end of this video, you will have a solid understanding of how to use window functions to efficiently calculate running totals in your SQL queries.
