This course will teach you how to use PostgreSQL to expand your queries to filter and combine data. Using SQL, you’ll learn how to join data from multiple tables, combine result sets, and use aggregate and window functions.
In this course, Combining and Filtering Data with PostgreSQL, you will learn how to expand your queries to retrieve additional data and achieve your desired results. First, you will learn the fundamentals of data types and how to work with string functions. Next, you will discover aggregate functions and how to filter aggregate results. Then, you will explore how to use joins to retrieve data from multiple tables. Set theory and unions will also be used to combine multiple result sets. Subqueries and common table expressions are introduced to help conduct more sophisticated analyses using multiple filter criteria. Finally, you will figure out window functions and how to partition and analyze data. When you’re finished with this course, you will have the skills and knowledge of PostgreSQL necessary to begin writing more complex queries to analyze data from multiple sources.

Course Overview [Autogenerated] Hi, everyone. My name is JSON Browning and welcome to my course. Combining and filtering data with post grads. SQL. I am the assistant vice provost for institutional effectiveness at Dixie State University in ST George, Utah. SQL could be used to access and analyzed data from multiple sources, and across multiple database is in this course. We will explore how to use SQL to aggregate information, joined despair it data sets and perform more advanced analysis. Some of the major topics that we will cover include aggregating data. How do we perform calculations on large groups or data sets combining multiple tables? How do we connect and use related data across various tables? Applying set theory. How do we work with multiple results? Sets writing sub queries How do we combine multiple queries to dynamically filter our data and window ING functions? How do we use these powerful analytic functions to partition and analyze our data? By the end of this course, you'll have the ability to write sub queries and apply SQL functions to perform more advanced filtering and combinations. You will also know how to apply window ING and aggregate functions to perform calculations across your data although the course is based in Post Grad, as much of what you learn will be applicable to any relational database platform, this course uses SQL and the post craze SQL environment to write queries and explore these functions before beginning the course. You should be familiar with basic SQL syntax, rotational database structure and the PG admin interface. To become more familiar with these concepts, feel free to check out my Pluralsight course querying data with post Grass SQL. I hope you'll join me on this journey to learn how to combine and filter data with post Grass SQL in this course at Pluralsight.
