Let me guess, you’ve taken an Intro SQL course and don’t know what to do next? Or maybe you’ve taken a few months or years away from SQL and need to brush up. Either way, this course is for you!

This course literally includes 101 Practice SQL Questions! In fact, majority of questions include multiple parts. Including those multiple parts students get access to 286 practice questions. This gives individuals ample opportunity to try, fail, learn, and succeed.

The instructional level is listed as “All Levels.” However, those taking this course do need to have some basic understanding of SQL. The course includes basic, intermediate, and advanced questions. This course will not teach you concepts step-by-step. You will learn by attempting the question, using a hint if needed, then watching the video explanation. Video explanations are provided to show students how to answer the question; however, each question has multiple answers. The instructor simply shows students how he would answer the question.

Microsoft SQL Server Management Studio (SSMS) will be the database management system used in the course. All the questions in the course are answered using the Microsoft Sample database, AdventureWorks. The syntax used in SSMS is T-SQL. T-SQL is similar to syntax used in MySQL, PostgreSQL, Oracle, Snowflake, MariaDB, etc., however, Microsoft SQL Server will be needed to load the AdventureWorks database.
