This hands-on, project-based course is designed to help you move beyond the six basic phrases and master advanced query techniques. We begin by reviewing the basics and performing multi-table analysis, including basic joins, self-joins, cross-joins, and unions. Next, we cover different ways to work with nested queries by writing subqueries and common table expressions, or CTEs. We examine examples of subqueries in various statements, rewrite subqueries as CTEs, introduce recursive CTEs, and compare these techniques to alternatives such as temporary tables and views. From there, we break down each component into a window function and examine common window functions such as ROW_NUMBER, RANK, FIRST_VALUE, LEAD, and LAG. We also cover general functions for working with different data types in SQL, including numeric, datetime, string, and NULL functions. Finally, we will apply the concepts we have learned to a series of common data analysis applications. We deal with duplicate values, apply eigenvalue filters, perform floating calculations, and more.<\/span><\/p>\n<h3 dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"17:1-17:91\"><span style=\"vertical-align: inherit\">What you will learn in SQL for Data Analysis: Advanced SQL Querying Techniques course<\/span><\/h3>\n<ul dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"19:1-24:0\">\n<li data-sourcepos=\"19:1-19:116\"><span style=\"vertical-align: inherit\">Perform multi-table analysis using JOINs and learn variations such as self-joins, cross-joins, and more<\/span><\/li>\n<li data-sourcepos=\"20:1-20:124\"><span style=\"vertical-align: inherit\">Learn to work with nested queries by writing subqueries and common table expressions (CTEs) and understanding the best use cases for each.<\/span><\/li>\n<li data-sourcepos=\"21:1-21:109\"><span style=\"vertical-align: inherit\">Use window functions to perform calculations on a set of rows and learn about different function options and uses<\/span><\/li>\n<li data-sourcepos=\"22:1-22:105\"><span style=\"vertical-align: inherit\">Discover the many SQL functions that can be applied to numeric, datetime, string, and NULL data fields<\/span><\/li>\n<li data-sourcepos=\"23:1-24:0\"><span style=\"vertical-align: inherit\">Apply advanced query techniques to common data analysis scenarios, including data rotation, dynamic calculations, and more<\/span><\/li>\n<\/ul>\n<h3 dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"25:1-25:30\"><span style=\"vertical-align: inherit\">This course is suitable for people who<\/span><\/h3>\n<ul dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"27:1-30:0\">\n<li data-sourcepos=\"27:1-27:110\"><span style=\"vertical-align: inherit\">Analysts or BI professionals looking to analyze data stored in relational database systems<\/span><\/li>\n<li data-sourcepos=\"28:1-28:71\"><span style=\"vertical-align: inherit\">SQL users who want to develop their advanced query skills<\/span><\/li>\n<li data-sourcepos=\"29:1-30:0\"><span style=\"vertical-align: inherit\">Anyone looking for a practical, practical, and highly engaging way to master SQL for advanced data analysis<\/span><\/li>\n<\/ul>\n<h3 dir=\"ltr\" style=\"text-align: left\"><span style=\"vertical-align: inherit\">Course specifications SQL for Data Analysis: Advanced SQL Querying Techniques<\/span><\/h3>\n<ul dir=\"ltr\" style=\"text-align: left\">\n<li><span style=\"vertical-align: inherit\">Publisher:&nbsp;
