13 Best Online SQL Courses for 2024 | All Major RDBMS Included

Structured Query Language or SQL is a standard query language for managing data stored in a relational database management system (RDBMS). Hence, it has become an essential skill for many careers in the IT industry, including in data science, software engineering, and web development.

If you want a lucrative tech career, you have to master SQL.

Fortunately, SQL is not too complicated to learn. You can excel in SQL effectively by taking online courses. They will help you gain knowledge and skills that will help you manage databases easily.

Nevertheless, you should not take any random online SQL courses since most are poorly created. Taking them can significantly delay your progress.

Instead, I recommend investing in only one or two high-quality courses. Upon completion, you will be ready to perform SQL-related tasks with confidence.

This article will thus feature only top SQL courses. You can select the one that suits your preference and budget to start learning immediately.

Things You Should Know


Unless indicated otherwise, most beginner-level SQL courses on this list have no prerequisites except basic computer skills. You can start learning without worrying about course requirements.


Below are the criteria for the best SQL courses

    SQL vs. MySQL, PostgreSQL, Oracle SQL…

    All courses on this list will teach SQL or the language used for querying databases. However, each may use a different RDBMS (aka the database system).

    The most popular RDBMS used in the courses are

    • MySQL
    • PostgreSQL
    • Microsoft SQL
    • Oracle SQL

    In other words, you will learn the same language (SQL) in all courses, but the system you use in each course (MySQL, PostgreSQL, etc.) may be different.

    Which one should beginners choose, then?

    I think that is subjective. However, MySQL is the most common database (according to the 2021 Stackoverflow survey.) Thus, starting with MySQL may be a promising option.

    1. Learn SQL Nanodegree Program

    This Nanodegree program from Udacity is not very different from the beginner-level courses I discussed above. However, the pace will be faster as it assumes that you have basic knowledge of data types (string, integer, etc.)

    This program is thus optimal for students who have a programming background since It will help them excel in SQL faster and provide opportunities to get valuable hands-on experience.

    Note: This program uses PostgreSQL. If you want to learn other systems, you may want to consider other alternatives.

    SQL Nanodegree program from Udacity is unarguably one of the best online SQL courses

    Course Content

    This program comprises two minor courses as follows:

    1. Introduction to SQL – The first course will introduce you to fundamental SQL concepts. You will learn how to execute essential SQL commands to perform various tasks, including joining & aggregating data and data tables.

    The second part of the course will drill deeper into advanced tasks, such as using subqueries & window functions, cleaning data, optimizing SQL queries, and many more.

    2. Management of Relational and Non-Relational Databases – The first part of this course will discuss methods to manage relational databases effectively. You will learn how to build normalized relational data models by using DDL to create schemas and migrating data utilizing DML.

    The second part of this course will introduce you to non-relational databases such as MongoDB and Redis. You will understand the difference between both types of databases and handily select the right one for various real-world scenarios.

    Both courses in the program are equipped with excellent learning resources. Each has numerous quizzes, exercises, assignments, and real-world projects for students to complete.

    Udacity’s projects are insightful and challenging. In the first course, you will use SQL to help analyze data and generate actionable insights to raise awareness about global deforestation and build database structures to support a social media news aggregator in the second.

    Hence, upon program completion, you will have sufficient project-building skills to showcase to recruiters and prospective clients proudly.

    Udacity suggests spending 10 hours per week on the program, which can be too intense for some students.

    However, this is hardly an issue as the program is entirely self-paced. Feel free to adjust the study time. Just keep in mind that the more time you spend on the program, the higher the tuition fees (see #pricing below)

        2. Introduction to Databases

        Not Available in 2024

        If you are looking for a comprehensive SQL course, this edX program created by New York University (NYU) is one of the best available. You start with the basics and progress to advanced database administration in one go.

        Note: This program utilizes MySQL, one of the most beginner-friendly relational database management systems. However, if you want to learn about other systems, please consider other courses on this list instead.

        NYU, introduction to Databases course provides one of the best SQL tutorial

        Course Content

        This program consists of three minor courses as follows:

        1. Introduction to Database Queries – The first course will introduce you to fundamental database concepts, organizations, and models.

        You will also learn about DML or Data Manipulation Language (a subset of SQL) and how to issue queries and develop them to perform CRUD operations (Create, Read, Update, Delete) to data stored in a database.

        2. Advanced Database Queries – The second course will explore interaction with relational database management systems. You will develop advanced queries in SQL that aggregate data and utilize subqueries and built-in functions.

        At the end of the course, you will design an efficient database for storing data and returning accurate results.

        lesson example of this program

        3. Advanced Database Administration – This final course will equip you with the required skills to manage RDBMS efficiently.

        First, you will learn about DDL (Data Definition Language, another subset of SQL), its syntaxes, and real-world usages. Later on, the course will discuss how to manage concurrency control and create objects in a database.

        Apart from the lessons, this program has complete assignments to test and strengthen your skills, like an on-site university course. If you score a 70% grade on average, you will receive three academic credits from Thomas Edison University (albeit not NYU).

        Regarding the learning pace, NYU recommends spending 6-8 hours weekly, and you will complete the entire program in 4 months. I think the pace is perfectly manageable for those with full-time employment.

        if you reside in the US, you can also access edX coaching services through SMS, email, and in-app messages. Your coach will assist you on career-oriented topics (resume, cover letter, interview) and help you stay motivated.

        Full access to this program, known as the verified track, costs $448 one-time. Alternatively, you can audit each course for free. However, you will not be able to access grading, coaching, and a digital certificate.

        I recommend auditing the first course beforehand. If you are satisfied, you can purchase the verified track later.

        Pros & Cons


        • Learn from a faculty member of a renowned university
        • Well-structured, comprehensive curriculum
        • Informative lessons
        • Excellent student assessment
        • Self-paced learning
        • Coaching access (available only to students living in the US)
        • Obtain three academic credits upon program completion (only if you pass the program with a 70% grade or higher)
        • Free auditing


        • Costlier than most alternatives

        3. Stanford’s Database Series

        Stanford University has created a series of five SQL and database courses on the edX platform. The series mainly covers the same content as an NYU program but focuses more on the database structure, background process, and other theoretical aspects.

        Stanford offers one of the best SQL courses.

        Course Content

        This series does not have bundle pricing. You will need to buy each course separately.

        1. Relational Databases and SQL – The first course will introduce you to relational databases and their systems. You will also learn fundamental SQL concepts.

        2. Advanced Topics in SQLThe second course will continue from what the first has left off. You will learn to create objects to increase query performance and use transactions for concurrency control and failure recovery.

        The second part of the course will discuss database constraints, triggers, views, and authorization in detail.

        3. OLAP and RecursionThis course will drill deep into online analytical processing (OLAP) features, including star schemas, the data cube concept, and the Cube and Rollup operators.

        Subsequently, you will learn about SQL standards for queries over recursive relations.

        4. Modeling and Theory – The fourth course is entirely dedicated to explaining theories. You will learn about Relational Algebra, dependency theory, and the Unified Modeling Language (UML).

        5. Semistructured DataThe final course will discuss JSON and XML standards for semistructured data. In the second part, you will learn about the XPath Language for processing XML data and its relevant features.

        Each course has exercises and assignments that you can work on to understand the concepts better.

        Stanford recommends spending 8-10 weeks on each course, and you will complete the series in ten weeks. The suggested pace is quite intense. However, the series is self-paced. You can set your learning schedule independently.

        You can audit each course for free, while a verified track costs $50 (or $250 or all five courses.)

                          Overall, the course content heavily explains PostgreSQL concepts, processes, and best practices. Once you complete the program, you will comfortably manage your own databases.

                          Though the course looks promising, it is not without drawbacks. First, Stephen does not provide massive, real-world projects for students to complete. You will need another course if you want to.

                          Second, and most importantly, Stephen will use Node.js in the last section. Hence, it is tough for those unfamiliar with this JavaScript runtime environment to understand the content thoroughly.

                          Because of this issue, I think this course will work best for web developers who already have some experience in backend development. Absolute beginners can undoubtedly take the course but will not utilize all course materials to their full potential.

                              In essence, you will learn everything you need to know to complete any PostgreSQL project. Adnan will explain every concept in detail and guide you through the entire process of managing PostgreSQL databases.

                              The only drawback is that Adnan can be extremely fast in his teaching pace. Some enrolled students need to decrease the play speed or even pause the video.

                                          Course Content

                                          The length of this video course is 13 hours. You will learn the following topics in detail:

                                          • Introduction to Databases and RDBMS + Installations
                                          • SELECT Statement
                                          • Filter and sort results
                                          • Operators & Group Operations

                                              13. Modern Big Data Analysis with SQL Specialization

                                              This Coursera specialization from Cloudera offers different perspectives compared to other courses. You will learn the same SQL but use it to analyze big data, not just smaller-scale data.

                                              Since this skill is highly in demand and lucrative, I recommend taking this course apart from the SQL course of your choice.

                                              In addition, students who plan to take the Cloudera Certified Associate (CCA) Data Analyst certification exam can use this specialization as their test prep.

                                              Important Note: This program has hardware requirements. Please make sure your current hardware satisfies them before enrolling.

                                              Big Data Analysis with SQL

                                              Course Content

                                              This specialization consists of three courses as follows:

                                              1. Foundations of Big Data Analysis with SQL – The first course will introduce you to the SQL language, databases, and big data. Subsequently, you will learn about SQL tools that you will use to work on big data platforms.

                                              Finally, you will be able to explore databases and tables in a big-data environment.

                                              2. Analyzing Big Data with SQL – In the second course, you will use different tools to navigate databases, learn steps to analyze big data, and answer analytic questions.

                                              You will use two big data engines: Apache Hive and Apache Impala.

                                              3. Managing Big Data in Clusters and Cloud Storage – The third course will mainly discuss strategies to manage big datasets.

                                              You will learn how to load them into clusters and cloud storage. Then, you will apply structure to those datasets, allowing you to use distributed SQL engines to run queries on them.

                                              As of October 2021, this specialization is under development. Cloudera still has not released the fourth and final course of the program, which will cover advanced SQL for big data analysis. If you want a complete learning experience, you need to wait for the release.

                                              Cloudera recommends spending 3 hours per week on the program; you will finish it in 4 months. The pace is thus perfectly manageable.

                                              Full access to the program costs $49 per month. Alternatively, you can audit each course for free, but your assignments will not be graded, and you will not receive a certificate.

                                              Pros & Cons



                                                  Other Alternatives

                                                  Below are other SQL courses that you may want to consider as well. However, some have issues or are simply not worth the investment at this point. Thus, I decided to leave them right here for now.

                                                  PostgreSQL for Everybody Specialization – I switched back and forth on my recommendations regarding this program from UMich. The program is well-structured, and you will learn PostgreSQL from a leading professor, which is excellent.

                                                  However, the program seems to be fragmented or incomplete in some parts. Also, the content is not very in-depth compared to those on the list. Hence, I think the cons outweigh the pros, so I chose not to recommend this program for now.

                                                  Still, since this is a Coursera program, you can audit the course for free if you want.

                                                  The Complete Oracle SQL Bootcamp (2023) – This online course on Udemy from Oracle Master training offers one of the most in-depth training for Oracle SQL.

                                                  The instructor will demystify the theoretical part by drilling deep into the details, allowing you to understand the concepts by heart and use Oracle SQL professionally.

                                                  Among all courses featured in this article, I think the curriculum of this course is the most well-structured. There are no giant leaps in difficulty or unrelated topics jumping out of nowhere.

                                                  Besides completing the video lessons, you can work on quizzes to test your skills. If you plan to take the exam, you can work on three newly-added exam samples at the end of the course (more than 200 questions in total).

                                                  The only reason that I did not include this course on the list is that I cannot understand him clearly. The instructor has a strong accent, and his voice is somewhat muffled. Student reviews indicate that many face this issue as well.

                                                  You can try taking some of the free lessons from the course page. If you have no problem understanding him, this course may be the best Oracle SQL course and definitely worth purchasing.

                                                  Dataquest – Having utilized interactive learning like Datacamp, Dataquest offers several SQL online courses on its platform. However, their content is even more limited than Datacamp. I don’t think it is worth the price ($24.50 per month) at this point.

                                                  Codecademy – Codecademy is another online programming school that utilizes interactive learning. Currently, Codecademy offers several SQL courses, ranging from SQL fundamentals to data analysis with SQL.

                                                  However, its SQL content is not as in-depth as Datacamp. I think it is not the best option to learn SQL online.

                                                  Related Courses

                                                  Once you have already mastered SQL, you may find this list of courses helpful if you want to upskill even further.
