使用 SQL 查詢數據

In this 55-minute course we will be querying data within a database by using various SQL statements. We'll learn how to find and manipulate data within a database. The amount of data that exists in the world is extensive and ever-expanding. Indeed, data exists all around us. As such, demand for data professionals has never been greater. This course is a continuation of my Introduction to SQL and Building a Database courses. While it is not mandatory to have taken these courses beforehand, please note that we will be using MySQL (which we learned how to download in Introduction to SQL) as well as the database that we created in Building a Database to query data. This is an exciting course on one of the most in-demand skillsets in today's professional world!
