Window functions perform calculations across a set of table rows related to the current row, providing insights without grouping the results. This allows for more complex analysis and better insights into your data.Next, we'll cover aggregate functions and their role in summarizing data. We'll see how the aggregate functions can be used within window functions to offer detailed analytics and how they can enhance our ability to analyze data.We'll then dive into the different types of window functions available. These include ranking functions like RANK(), DENSE_RANK(), and ROW_NUMBER(), aggregate functions like SUM(), AVG(), COUNT(), and MAX(), and analytic functions like LEAD(), LAG(), FIRST_VALUE(), and LAST_VALUE(). Then we will learn about syntax of window functions which will enable you to write effective and efficient window function queries.Finally, we'll see window functions in action. We'll demonstrate how to use them in practical scenarios, such as calculating moving averages, running totals, and ranking rows within partitions. By the end of this video, you'll have a solid understanding of window functions in SQL and how to leverage them for powerful data analysis. 00:00 Introduction 01:37 What is Window Function ? 02:04 What is a Agrregate Function ? 07:18 Different types of Window Function ? 11:52 Syntax for Window Function ? 13:15 How to use a Window Function ? ✅ Subscribe to our Channel to learn more about the top Technologies: https://bit.ly/2VT4WtH ✅ Know More about Simplilearn here: https://www.simplilearn.com/?utm_campaign=06Aug2024-Window-Function-In-SQL&utm_medium=Description&utm_source=youtube #HowToWriteWindowFunctionInSQL #RankFunctionInSQL #DenseRankInSQL #WindowFunction #SQL #mysql #PostGRESQL #2024 #simplilearn ➡️ About Data Analyst Master’s Program This online data analyst course will transform you into a data analytics expert.
