SQL Exercises For Beginners And Intermediate Learners
For most students, SQL could be among the easiest programming languages to look at because the codes read the same like regular English. You will often find the three magic words SELECT, FROM, and WHERE as the core in database querying. But later on as you progress, you will find more complex statements for joins, aggregations, case statements, and subqueries which can be intimidating for newbies and even intermediate learners.
The good news is that SQL shouldn’t scare you at all, especially for business and marketing students who don’t have a coding background. We have tailored our guides and exercises specific for business and marketing applications, hoping to help SQL newbies start coding right away or even experienced users of SQL who wants to learn a new perspective in data analytics.
What You Can Learn from the Tutorials
Learning and remembering the lessons are simpler when it is designed to be something intuitive. Our guides and tutorials aim to break the barrier of entry for non-technical or non-developer students and professionals who will find SQL useful in their career. We hope that new and intermediate learners will be able to master the fundamentals of database querying with a lesser amount of time.
SQL newbies are expected to learn how to use the keywords SELECT, FROM, and WHERE statements in manipulating data. These are the fundamentals of database management until you progress to the more advanced skills useful in data analytics.
To up your skills, you will then have to go through the intermediate level tutorials where you will be introduced to more complex statements and database manipulation techniques. Among the most important topics to learn are common operators for numerical and non-numerical data, how to sort data using the ORDER BY statement, aggregations, how to manipulate rows and columns, how to use GROUP BY with ORDER BY and HAVING phrases, and CASE statements.
Problem Sets and Exercises
The learning experience wouldn’t be complete without problem sets and case studies you can practice to apply your newly acquired skills. Instead of a generalized approach, we have designed our problem sets that tackle common problems encountered in business and marketing. Here, you will have to use your SQL and analytical skills to manipulate or retrieve data, make visualizations, analyze trends, and make a sound judgement based on your solution.
Our problem sets are continuously being updated to constantly challenge your skills! We have included questions that are related to common business problems, such as the Forbes Global exercises, French Employment Exercises, Hotel Reviews Exercises, Library Usage Exercises, QB Stats Exercises, Spotify Exercises, and Yelp Exercises. Case Studies are also available for the more advanced learners. Here, you can use any languages you like aside from SQL to answer open-ended questions. You can use all of these problem sets and case studies for your projects as well. Intermediate and even experienced SQL users can find these problem sets helpful for review and references.
We hope that through our tutorials and problem sets, we are able to help you build your confidence in SQL and data analytics. We encourage you to master our guides and exercises to ace in your business and marketing career.
