This video gives an overview of entire course.
The aim of the video is to install Postgres on Mac and Windows operating systems.
The aim of this video is to install pgAdmin, our SQL query interface and learn its general usage.
The aim of this video is to import our first dataset, the DVD rental database.
The goal of this video is to build the mental model of SQL by exploring the SELECT, WHERE, GROUP BY and COUNT clauses.
The aim of the video is to use the most common JOINS namely INNER and LEFT bringing data together.
The aim of this video is to learn more about LEFT JOIN and also about SELF JOIN clause to help bring data together.
The goal of this video is to select from queries and nesting your SQL.
The goal of this video is to learn the common JOIN and filtering Gotchas mistakes to avoid.
The aim of this video is to use strategies for filtering on aggregates.
The goal of this video is to filter your data using subqueries, a useful and very flexible filtering strategy.
The aim of the video is to compute many similar values, avoiding JOINs.
The aim of this video is to use common table expressions to turn messy queries into organized code.
The aim of this video is to use strategies which will help sort data into dates and time for analysis.
The goal of this video is to use the CASE statement, which is similar to the IF”statement of SQL.
The goal of this video is to learn how to insert external data.
Many of us know a bit of SQL. But when it comes to answering real-world business questions, our rusty memories of database classes let us down!
This video course will take you to an intermediate level of familiarity with SQL in the context of writing maintainable and sophisticated SQL for specific business queries. You will start by importing our first dataset which will be the DVD rental database. We then will explore and put into practice various SQL clauses and Join types. All examples of fundamental concepts are tightly guided by practical and hands-on exercises. No “Foo Bar” allowed anywhere, just problems from the wild, brought into the educational space. You will also learn tricks to get external data into the database, without worrying excessively about DBA functions and considerations.
You’ll also find out how to take the data into popular BI tools (Excel and Tableau) and refine the analysis further while discussing the interpretation of the data. By the end of the course, you will have developed your SQL skills and learnt how to answer business questions from the set of data.
