SQL (structured query language) is probably the most popular database organizational language in the world. Whether it’s saving your work on a website, writing tickets on your Jira board at work or deleting old account files from a video game – databases are at the foundation of many IT and Internet of things (IoT) systems in all facets of society. With all its popularity, it’s no wonder massive open online course providers like Udemy and Coursera offer thousands of comprehensive online SQL courses. I personally have learned many of my SQL database skills from the Udemy SQL courses provided!
Most software engineer jobs require a strong foundation of SQL, or a related database language due to the need of being to store data and then subsequently call upon it when needed.
However, business jobs like business systems analysts (BSAs), product managers and even general marketing or reporting analysts, may need to call upon SQL as a skill to extract, load and transform (ETL) large data sets. Data is the lifeblood of everything we do, and being able to organize and manipulate is a sought after skill!

My experience with Udemy SQL courses
Like me, most business individuals needed to self learn these skills. The best place to do that was on MOOCs since you could learn at your own pace, have easy access to large datasets and learn real life use cases that are applicable to the workforce.
This is where Udemy SQL courses can come in handy. From my experience and as a lifetime learner, I’ve completed and started at least 6 individual SQL courses.
I’ve noticed a trend among the SQL courses that I’ve either done myself or audited on Udemy:
- They’re shorter than your average tutorial courses (6 – 10) hours, which is a good thing.
- They normally have excellent sample datasets which some MOOCs struggle with.
- A lot of the more sticky SQL subjects (Triggers, Procedures, Function building) are well documented and usually in-depth.
- The course creators try to steep the course from a practical point of view, instead of learning theory. This means you learn skills that can help you in the real world.
- There are tons of courses that cover database design and architecture, data analysis and big data. All extremely big topics in our modern age.
- You get lifetime access. This is good especially with technologies evolving so quickly.
Ultimately, the purpose of me creating this guide is to provide you with the best Udemy courses about SQL. I didn’t limit this guide to just normal run of the mill SQL. I also include courses for NoSQL, MySQL and Postgresql so that you can grow your own skills and get that job that you’ve always wanted :).

Overall Best SQL Course on Udemy – Jose Portilla’s Zero to Hero SQL Bootcamp
This 9 hour course has a variety of things that make it a top notch SQL bootcamp.
- A ramp up from zero-to-hero. The ramp-up is fairly slow, but it’s an easy to understand / methodological approach to learning a coding language.
- After every section there’s a challenge, here’s an example of the Chapter two challenge. It may seem easy, but you end up building the muscle memory you need.
- You cover a good set of advanced concepts like joins (including union), mathematical operators, subqueries, procedures and conditionals.
- There’s a small project at the end of course, with large 30 minute assessment tests after every three chapters.
- There’s also some python at the end mixed in with your querying so that you can get a taste for the data science or machine learning side side of the SQL.
Above is the schema of the database that you will be working with, this is a complex database!
- Great compact course, not too long and not too short.
- Great workbook material and data resources (practice database is a good size)
- Awesome ramp-up for the course (a true zero to hero)
- Good test, quizzes and exercises
- Jose is very well-spoken (in english) and articulates himself quite well when teaching
- The section pacing was perfect – “group by” and SQL fundamentals (SELECT, COUNT etc..) are fairly easy concepts which can be covered in two hours. Whereas having JOINS and UNIONS with their own 1.5 hour section each, allows you to get the practice you need.
- While there was good coverage on create, read, update, delete (CRUD) queries, I think there could have been more theoretical overview on how DBs work and what SQL does (only a small 8 minute session).
- They cover procedures and JOINs, but no user-defined functions? User-defined functions are an extremely important concept for SQL. The ability to pass and store variables is an extremely important skill to learn for SQL.
- There was also nothing on views or triggers as well.
- It would have been nice for Jose to cover MySQL, Microsoft SQL server (MS SQL) or even Oracle since the syntax is different, everything is Postgresql based.
Who this course is for
- Anyone who wants to learn SQL from scratch (as long as you have worked with computers, you will come out of this course more knowledgeable).
- Someone looking to start out slow and learn tech. If you’re new to tech, and want to learn a “coding language” this is the type of course to start out.
- A person looking who is curious about tech or SQL but has limited experience or knowledge in either.
Who this course is not for:
- Experienced developers will find this course boring. This is definitely not an advanced SQL course.
- Anyone hoping to get some experience with SQL server or MySQL databases.
- Anyone hoping to interact with an application VIA code (like PHP). For example MySQL is the type of database used for WordPress. You can use generated user interfaces (GUI) like PHPmyAdmin to interact with the database directly. This is a pure SQL course with a little bit of Python mixed in at the end.
What customers say about Jose’ SQL course
It is a relatively complete tutorial, but I still feel the sequence of execution of the SQL clauses should be added in order to give the students a deeper understanding of what they are doing.Shuaidong Y. – 4.5 / 5 stars – April 2022
This course was just what I needed, and for a reasonable price too! I now feel more confident with SQL and will probably go over the course a couple more times just to get to grips with using it. Definitely recommend!Mr James B. – 5 / 5 stars – May 2022
The instructor was great. He made the lessons very easy to understand. I deducted half a star because you can’t do anything with the last section if you don’t know PythonJuthamard A. – 4.5 / stars – April 2022
Overview of Jose Portilla’s Zero to Hero SQL Bootcamp
This course is awesome, I would call it SQL 101. Jose’s a master web development teacher and I reviewed his Python Django course which I thought was great. Regarding this SQL, I’ve finished the course and while I found it fairly easy (I’ve been running queries for more than half a decade), I still think it’s a great course to pick up and learn about SQL. While there may be better courses that are more in-depth, this covers all the basics. One thing to note is; Jose is not actively updating his lesson (last update was 5/2021 when I wrote this article), but this is a fundamentals course which means there’s very little they may be able to change or update. Who knows, in 6 months Jose’s course may no longer be the best SQL course on Udemy :). Overall though, fantastic course and definitely worth picking up.
Ultimate MySQL Bootcamp -Go from SQL Beginner to Expert by Colt Steele.
An extremely comprehensive 20hr+ SQL course that is a true beginner to expert course with hundreds of articles and quizzes, a fantastic introduction to SQL and database architecture plus meaning other great subjects. Here’s a list of what you’ll get to learn:
- String management (CHAR, UPPER, LOWER, REPLACE, SUBSTRING).
- Mathematical / aggregation functions (MIN, MAX, SUM, AVG).
- Breakdown of data types (FLOAT, DOUBLE, CURDATE, NOW).
- Logical functions / conditionals (AND, OR, LESS THAN, GREATER THAN and CASE)
- JOINS (inner, outer, self)
- Two projects
- TV Joins
- Instagram DB
- Working with DB in Node.js (NPM and Faker).
- Building a webapp with EJS templates (Node.js)
- Database triggers
- This course is comprehensive. It has a great ramp-up from not knowing anything about SQL to being able to deploy your own web application VIA NodeJS while flexing your newly acquired SQL concepts.
- Ian Schoonover and Colt Steele are great teachers, well spoken and articulate even the smallest terms.
- A project!! The Instragram database is a great project, accompanied with a schema, hashtags and other coding problems.
- This is the first course I had actually seen that had a whole chapter on string manipulation. This is an extremely important concept in SQL, since data that’s entered into a DB may not always be the same and it usually will need to be transformed. String manipulation VIA SQL queries is one of those ways that you can make those changes.
- Almost 2 hours of logical operators which I use all the time when I’m running queries. The OR and AND statements are very popular in SQL.
- Three hours of join practice :). If you want a lot of practice doing JOINs (Inner, Outer, Self) and intersect + union, this is the course to take.
Glad to see a section on triggers and search refinement (LIKE, DISTINCT and WILD cards). For ad hoc queries, I love using LIKE or REGEXP. However, they tend to be bad for querying speed.
- No user-defined functions chapter. This was strange to me because the course seemed like it could easily be set-up for it.
- It is 20 hours, so while that’s a lot of SQL – it’s longer than your average course.
- Sometimes, Colt and Ian’s interludes before the lessons seemed redundant so I found myself skipping them. This is due to my experience with SQL. If you have no experience, I can see them being a benefit to listen to.
Who this course is for
- People who want an in-depth understanding and experience in SQL. Colt and Ian do a great job giving plenty of SQL knowledge to a newbie.
- A business analyst or person who wants to start their journey in SQL.
- A software developer who wants to expand their SQL skills (understanding that you may want to skip the first half of the course).
- Someone who wants to build something end-to-end (starting with the very basics of SQL, and deploying an application that can run CRUD operations on a DB).
Who this course not for
- Someone who wants to learn NoSQL or SQL server. This course primarily focuses on MySQL.
- A senior engineer or database administrator – this course will be too easy for you.
Customers love Colt and Ian’s bootcamp! Here are some testimonials!
Every concept was very well explained. The only thing which I felt missing was the window functions. I wish a separate section like the “triggers” would get added as a part of an update in the future. Anyway, I still like the course.Aravind R. – 5/5 Stars – April 2022
It was pretty good, I wish there were more practice problems. Also, I wasn’t that interested building the web app portion. I also found that goormIDE was super buggy at times and I would need to keep refreshing the terminal, which was super annoying.Grace S. – 4 / 5 – April 2022
Colt is crazy (fun crazy) but he knows his stuff. This is my first course on databases and SQL code and while it hammered my brain cells, it was very informative. It has given me a foundation to transition from my current career into the world of data analysis. Thanks heaps, Colt.Duncan M. – 5 / 5 stars – April 2022
Not surprised that Colt has created another awesome course, his web development course was also great. Overall, this course has lots of nuggets of information and lessons that you can easily take away. The NodeJS app + MySQL course project at the end was a really big treat, and I think that’s one of the biggest selling points of this course.
It allows you to build a real world application and understand the purpose of learning all of those queries and the syntax. Coupled with the fact that Colt and Ian have kept the course updated and this course may soon become the best SQL course on Udemy.
For now, it’s a runner-up to Jose’s SQL course. Ultimately, I think this course may be more comprehensive if Colt and Ian added user-defined functions, or maybe another project on how CMS’ interact with MySQL. If they added these two things this course would be truly magical in my opinion.
Best Data analytics and Business SQL Udemy Course by 365 Careers
Another great MySQL course which is geared towards analytics and business intelligence. This course has a Tableau integration chapter at the end. This is fantastic if you want to start to have a better understanding of BI and work with real tools companies use.
The course has the following breakdown:
- Tons of SQL theory, and foundational work (like how to set up a DB, how to load information into a DB).
- You use MySQL workbench to run the queries (which is a great GUI in my opinion).
- You’ll spend time breaking down constraints like foreign keys, primary keys and NOT NULL.
- Over 3 hours on SELECT, INSERT, UPDATE, DELETE, aggregate functions (COUNT(), SUM(), MIN(), MAX(), AVG()).
- Stored routines
- Global / User defined variables and conditionals (CASE, AND, OR)
- Indexes and Triggers.
The course ends with about an hour of SQL and Tableau magic which is a great way to end the course (in practical usage of SQL).
- Great progression and general overview of many different MySQL commands
- Good exercises and review of each chapter
- I love MySQL workbench, I’m happy 365careers showed me this because I still use it.
- Great Tableau project at the end of the course
- First course that actually brought up Data definition language (DDL), Data manipulation language (DML), Data control language (DCL) and TCL – Transaction control language.
- True to form, there’s a great segway in this course from spreadsheets into databases
- Finally someone brought up stored routines and parameters!
- The sections were a little light. Views was only a 7 minute video, self-joins (8 minutes) and subqueries (17 minutes). All of these sections could be courses on their own!
- You only end up using Tableau public, which is a public open-source version of Tableau with limited features. Having used Tableau Desktop, the versions are very different.
- While the exercises were good, sometimes they were too similar to the actual lesson. This made the exercises too easy. However, the final section (which is basically a test) has great questions covering all of the course material.
- Since this is a business intelligence course, we could have benefited from learning other visualization tools like DOMO or Google data studio.
Who this course is for
- Someone looking to learn MySQL from scratch and begin to learn the data visualization tool Tableau
- A jr. data analyst or business analyst that needs to understand how to query from a data-set, and extract that data to visualize for business use.
- Anyone looking to have a great overview of MySQL, (this course touches on a lot of sections albeit very small sometimes).
Who this course not for
- A database administrator (DBA), or someone looking to become a DBA. This course may start you off in the right direction, but is not comprehensive enough.
- A web developer or someone looking to build applications, this course is geared towards BI and Excel usage, not the creation of applications.
See what some users say about this BI SQL course!
This course was a great way to learn SQL and Tableau. The sections were easy to follow and the resources are a great tool to have to keep practicing in the future.Mary C. – 4 / 5 stars – January 2022
Enjoyed every bit of this course, especially the practice problems, and the section which involved data visualization using Tableau. Also the coursework is beginner friendly. Would recommend this course to anyone who is looking to learn SQL for business analytics as a beginner.Shaloy Elshan L. – 5 / 5 stars – February 2022
It was a fantastic course. It was well structured from basic to advanced level MySQL coding. I started out as a novice but I am up for challenges now. Thanks to the instructor.Arijit S. – 5 / 5 stars – April 2022
Another course I’ve done from start to finish! It was a great experience and allowed me to learn stored procedures and how to work with Tableau and MySQL. This course is high quality, while also being simple enough if you have no SQL skill. I’d recommend this course if you’re a business person trying to learn how to understand MySQL. While I would have liked to see some SQL server and an intro to Python or R, that’s definitely more of a data science thing.
Best SQL Udemy course with BigQuery and Google data studio – by Chris Levy.
Since it’s so popular and I have some experience with it, I figured that I would also throw in a BigQuery, Google analytics / Google data studio course as well! This course, created by Chris Levy, is a 7 hour course where you’ll learn generic SQL statements on Google BigQuery and then visualize them in Google data studio. The types of SQL commands you’ll learn are SELECT, WHERE, JOINS, Aggregate functions and CASE. You will also go over specific how BigQuery works with Cast, string and date + timestamp.
The course has two hands-on projects.
- This course is a perfect length for what it’s supposed to provide. While it’s not a comprehensive deep dive in SQL, it gives you SQL understanding to work with BigQuery and build plus visualize your own information in Google data studio (GDS).
- The course has two hands-on projects; one is very in depth (build out your own dashboard),and the other is more of a walkthrough talkthrough.
- Chris is well spoken and easy to understand.
- The creation of the data studio dashboards is actually fun!
- It’s not a full SQL course, so you may learn a few queries and how to run them – but without more practice you’ll be far from an expert in SQL
- DISCLAIMER – if you sign up for a Google cloud platform account, make sure to turn off the usage after you’re done the course, or GCP will charge you for having an operation Bigquery.
- The course is a little outdated, so it could definitely use an update.
Who is this course for:
- Someone looking to learn SQL for data science and to create some dashboards
- A digital marketing or digital analyst who is tech and wants to learn some neat skills
- A web developer who wants to broaden their skills and do some data visualization
Who is this course not for:
- Someone looking to learn SQL period – this course is more of a “SQL data science course”.
- Anyone pursuing the career of database administrator or architect
- Someone looking to purely go into Data science (you’ll need a ton of other tools like Matlab, Python, R).
What did students say about this Google data studio, BigQuery SQL course
Great course, but would have liked to have seen one of the queries exported to Python (as a bonus video) like he previously mentioned.Gail C – 5 / 5 stars – April 2021
Great course! The course is a really good and quick introduction to Big Query. It touches most of the fundamental topics and some of the functions that will be commonly used in queries. A good foundational course which can be leveraged to develop more skills in BigQuery.Sagar D. – 4.5 / 5 stars – May 2021
Great, easy to understand instructor and course!Joan R. – 5 / 5 stats – May 2022
A great little fun course that while out of date, can still provide valuable skills you need in this competitive landscape. I would say that if you want to get your feet wet with an easy data science course – I would highly recommend this course as a starting point. If you’re looking for something more comprehensive in data science, consider an ML course like Kirill’s Hands-on python & R in Data science or a straight-up data science bootcamp.
Best Udemy Course for PostgreSQL by Stephen Grider
This 22 hour long PostgreSQL course is built differently than the rest of courses mentioned in this SQL guide. The course does the following:
- A 40 minute introduction on how SQL works and what it does
- How to work with tables – CREATE, DELETE, UPDATE, DELETE (CRUD)
- JOINS, Aggregate, manipulating large data-sets and then a small lesson on Sorting (order by, group by)
- Unions and intersections
- Almost 2 hours of subqueries!
So this course starts with roughly 6 hours of learning. Then the course looks at how to theoretically build a “Mention”, “Hashtag ” and “Follower” which are all important to creating a strong database infrastructure.
The course then dives into more advanced stuff like indexes, common table expressions, recursive table expressions, views, database schemas and even working with APIs in Postgresql. The course finishes off with security around Postgresql and parallel testing (both I have no practical information about).
- This is a comprehensive course, and touches a little bit of everything that you need to know about SQL.
- It’s great that there’s a ton of strategy and infrastructure planning in this course + the practical skill of querying.
- 2 hours of subqueries – better than some entire courses.
- 1 hour of indexes – this is amazing!
- It was neat to learn about parallel testing so that you can test how fast the queries run side by side. This is so that you can optimize their speed.
- Stephen Grider is a great teacher, well spoken and methodical.
- Course has been recently updated (March 2022).
- You’ll learn how to use PGadmin an interface use to interact with Postgresql.
- It is a long course in the way of SQL, and while there are over 20 coding exercises, there’s actually a fair bit of less hands-on work.
- Honestly, I was a bit shocked that there were no stored procedures or user-defined functions. This course touches on literally everything else!
Who is this course for:
- Someone who wants to learn SQL pretty well, this is a great course specifically on Postgresql.
- A person looking to dive straight into Postgresql without any development skills.
- Anyone looking to get into Python development (It uses Postgresql)
Who is this course not for:
A senior engineer or programmer.
What do the learners of Stephen’s course think about it?
An amazing course!, it covers the basics and then goes in-depth into certain practical concepts you’ll encounter/need when working on real-life applications.
Totally worth it!Obielium G. – 5 / 5 stars – January 2022
Quite possibly the platonic ideal of a course on SQL. Hardly a single wasted moment; no confusion or things not working as expected; clear and succinct. Elegant parsimony that only enhances the student’s understanding. Kudos, bravos, roses, and untold riches to the instructor.
SELECT * FROM courses WHERE course_name = ‘SQL and PostgreSQL: The Complete Developer’s Guide’;James B. – 5 / 5 stars – April 2022
You are amazing, I can’t thank you enough for this course. You are an awesome lecturer, I understood all the concepts even the advanced ones very easily!Peter K. – 5 / 5 stars – February 2022
This is a great course, and I think after some of the web development courses I have lined up from my previous article, I might actually get to finishing this one. The ratings are high for this course, it’s well structured and it’s all about SQL.
Best NoSQL / MongoDB course on Udemy by Maximilian Schwarzmuller
MongoDB, a derivative of noSQL, is a newish (first coined in 1998, with MongoDB coming out in 2007), framework that is meant to be lightweight, more nimble and easier to use than other relational databases (rdbms) like MySQL and SQL server. That being said, the syntax is very similar to other SQL frameworks, so the transference of knowledge on MongoDB vs. any other relational DB should be quick.
You’ll look at the following:
- How to use JSON and BSON for MongoDB
- Working with arrays and embedded objects.
- Create, Read, Update, Delete (CRUD) in MongoDB
- Schema and relationships in MongoDB
- Data types
- MongoDB Compass
- Shell usage in MongoDB (Config file)
- Aggregation Framework
- Security in MongoDB
- Deployment, Transactions and an introduction to Stitch (an SDK that allows secure transference of data).
- Lots of MongoDB knowledge, holy cow. I plan on diving deep into MERN and Ruby On Rails (which uses SQLite) after I finish my PMP and I haven’t seen such a comprehensive noSQL course on Udemy to date!
- You’ll learn how to use MongoDB atlas, which is a great tool if you’re doing cloud administration.
- There’s also a quick crash course on Stitch
- It’s taught by Maximilian who has dozens of other courses on Udemy and is a fantastic teacher.
- So, this isn’t an “SQL” course per se. NoSQL does function quite differently than other SQL languages despite sharing some similarities. Ultimately, because they function so differently – you may find yourself needing to take other SQL courses to compensate for the lack of actual querying.
- There was only 4 hours of actual querying in normal SQL syntax, the rest of the training was specifically meant to actualize, deploy and work with configurations for MongoDB.
- Why isn’t there more information on how MongoDB interacts with React!!
- There’s nothing talking about Mongoose, which is a popular framework to deploy MongoDB and JS applications.
Who is this course for:
- Someone looking to learn MongoDB
- Someone who wants to learn NoSQL or polish their NoSQL skills
- A web developer or data scientist who wants to learn how NoSQL or MongoDB works
Who is this course not for:
- Not meant for someone looking to do DB administration of MongoDB servers
- A beginner or someone who has no technical knowledge / experience. This course gets pretty detailed when it comes to Stitch and other fancy tools. If you’ve never ran a query or done bash, it may be difficult for you to keep up.
- Someone looking to integrate their React application or someone looking to learn about Mongoose.
What do these NoSQLs customers think of the course?
At first Max introduces the content as a bit of a firehose, mostly running through offerings in the documentation almost enumeratively. He’s fast and in my opinion a little scatterbrained – but in the end he has a good grasp of how the technology operates, how to secure it, and how to optimize it. It’s solid instruction and succinct enough to not waste time.
Jumped ahead early on to implement an MVC API solution using C#, which was my incentive for taking the course. The lessons learned so far have proved very useful. On a side note, I have noticed that that some of the features presented are now deprecated such as update. Might be worth inserting a quick update between topics to cover this. Overall, instruction is comprehensive and well planned. Wish the coding examples would include C# but you can’t have everything.Richard N. – 5 / 5 stars – March 2022
A very good course for people who never touched NoSQL / MongoDB. Like the title says, the course is aimed at developers and not admins. But even if I am a dev I would have liked more insight into sharding and replication anyway… (But this is NOT why I subtracted 1 Star)
It would be better if the example commands would be well formated all the time and not only in the aggregation module…
This reduced readabillity quite a bit especially in the operator sections.
I do not regret the purchase at all 🙂Tom – Henry C. – 4 / 5 stars – December 2021
Great course if you’re looking to learn NoSQL or MongoDB, not the best course if you’re looking specifically to learn MySQL or another database management system. If this course had something outlining Mongoose or focused more on React, it may be a little more relatable to development folks. However, this is a solid course and has already been added to my wishlist of things.
Here are the top 6 SQL courses on Udemy.
- Best SQL bootcamp by Jose Portilla
- Runner up Best SQL boot camp by Colt Steele and Ian Schoonover
- Best for MySQL and Business Intelligence by 365 Careers
- Best SQL Udemy course with BigQuery and Google data studio by Chris Levy
- Best Udemy Course for PostgreSQL by Stephen Grider
- Best NoSQL MongoDB on Udemy by Maximilian Schwarzmuller
Note :a quick shoutout to Brewster Knowlton’s Microsoft SQL for Beginners course which teaches SQL Server and T-SQL. This framework (SQL server) is becoming a little less popular, but this course seemed great for what it’s teaching. It’s only four hours, so you can probably take it within one weekend if you want.
I hope you’ve enjoyed this article I’ve put together for you. The purpose of it was to provide you with a number of modern SQL courses on Udemy so you could grow your skills. SQL by itself isn’t all that useful since it’s used to interact with the data. So unless you’re planning on being a database administrator or architect, it’s likely that SQL is a skill you need in your comprehensive engineering tool kit. Whether you’re a web developer, business analyst, project manager or even a marketer – you may need SQL in your career, and Udemy is a great way to learn, polish and broaden that skill.
Let me know if there’s anything I missed in the comments!
Although the courses are good on Udemy, comprehensive with a ton of theoretical and practical SQL tutorials, you can’t master SQL solely by learning it on a tool like Udemy. You need to run queries, work with production data in the real world data. Udemy gives you a strong introduction to how SQL works – it’s up to you to master the language.
There are very basic free SQL courses that will provide some practice and theory – but nothing as comprehensive the courses you may pay for. To learn a programming language is not easy, it takes dedication and hundreds of not thousands of hours of work. These free courses just can’t provide that.
If you only take Udemy courses and apply for a job to become an SQL developer, I almost guarantee you that you won’t even make it to the screening interview. Most positions require years of experience and with that, real-world data manipulation. You may have a good understanding of normalization, but if you’ve never done it in a production environment before – you’ll likely struggle to figure out solution when confronted with that issue.
Ultimately, I think Udemy shines in covering a wide range of topics which can help you to begin to be knowledgeable about a subject. I also find that because you can so easily consume Udemy courses, it makes it an invaluable tool to ace interview questions.
