r/learnSQL on Reddit: What are the best websites or apps to learn SQL as a complete beginner?

July 9, 2025 -

Hey everyone! 👋

I’m just starting to learn SQL and I’m looking for some solid websites or apps that are beginner-friendly. Ideally, I’d like something interactive or hands-on rather than just reading theory. I’m not aiming to become a full-on data engineer—just want to get comfortable writing queries, understanding databases, and maybe do some small projects.

Any recommendations for platforms (free or paid) that helped you when you were starting out? Bonus points if they have exercises or real-world examples!

Thanks in advance! 🙌

I (27m) want to switch my exhausting current job to programming.I heard that learning SQl can provide you a good chance to land a data analyst job. Also are there any other languages that i should cater to as well.

u/PopGroundbreaking966 I highly recommend using https://sqlbolt.com/ Very easy to follow mini tasks that you complete on the site itself to give the basics of understanding tables, columns and rows and the most basic SQL statements. Do yourself a favour and spend 20 minutes on it today. Used it when I got into software engineering.

Freecodecamp has free resources and different focuses you can choose from, that and YouTube can point you towards some lesser known ones too.

Hello! I am looking to learn sql as I feel it will be valuable for me to learn. I was unsure where to start though, and was wondering if anyone could point me in the right direction to a great free site/course for me to start at? Thanks!

To practice SQL, you can use www.sqlclimber.com . It is free, but there is no theory, only practice.

I did the SQL Tutorial - Full Database Course for Beginners from FreeCodeCamp like 4 years ago. That a shit ton of google and playing with a bunch of databases helped me.

I'm currently learning SQL in my spare time, polishing up on my Excel skills and after SQL, I want to learn PowerBI. I have NO EXPERIENCE in SQL.

Which books, mock test, website, youtube channel would you recommend? I want to learn from basic to expert level no matter how much time it takes?

You could start with the SQL section of w3schools.com. It's a big picture overview of SQL and it has some pages focused on how to accomplish things specific to different database programs. Get comfortable with that first. The rarely spoken truth is that SQL isn't very hard to pick up. Your value will largely depend on your ability to translate business logic into SQL. Practice. Pick an industry/type of business. It might be best to start with one you're very familiar with on your first run through. Set up your database environment. Securely store all the information required in your set up. Ex: authentication type, administrator account user/pass, database name, etc Gather information on what the business would need to store in a database. Ex: an animal shelter would need a pet table, a kennel/cage table, immunization/medical information table, license/tag table, a table to store people who surrender or adopt .. you get the picture. Make it as detailed as you can, if it's realistic, talk to someone in that line of work, but don't get caught up in making it perfect. 5-10 tables should be enough for the first time around. Design the tables in the database. Pay attention to data types as you go. You'll want to consider the data as it is today, and accommodate for growth. Ex: your table has a field, char(10) as the data type. The data stored is currently 10 characters long. Business needs change, and this field now needs to store 12 characters. Save yourself the headache and start with making it varchar(20) at creation. Also pay attention to keys and how you intend to join tables. I strongly advise putting primary keys on every table and setting them to auto-increment. This gives you a quick out when it comes to duplicate records. Generate data for your tables. Google "data generator" and find the one you like the best. I've used https://generatedata.com/ in the past, it's not terrible but I recall a lot of tweaking to get exactly what I needed. Research. Chances are there's something easier out there. If dropping money on it is not an issue, Regate has a SQL Data Generator for a yearly subscription price of $264. Probably easier to work with. Load your data into the database. Ideally, the data generator provided you with a SQL script that runs a bunch of inserts, one click and done. But it's possible you got a csv or Excel file. Most dbms's come with an import tool of some kind, this the perfect opportunity to learn how to use it. The rest is the fun part. Conjure up potential business scenarios your business might encounter. In the animal shelter example, a couple things might happen: animal adoption, animal surrender, kennel change, new license/tag, etc. Consider what would be most important if you needed to report on these situations, put some queries together, maybe create some views. When you're pretty comfortable with that, start looking into how you'd update data. An animal surrender wouldn't just be entering into the pet table, you'd also want to store the person who surrendered the animal and assign them a kennel. Also: retaining historical data for record changes is a valid business requirement. If it didn't come up in your original design, figuring out how to implement it is good practice. Sorry so long, but it should get you started and introduce you to some situations you're going to encounter later on. Lots of luck!

W3 schools is a great resource and it is free so you can explore all you want before focusing on ay flavor of SQL.

I'm starting to have decision paralysis. There are many courses people recommend, but if I'm going to be paying for one, I want it to be the very best.

I'd prefer one with lots of exercises (rather than merely watching videos), since I learn best by doing.

Personally I took two different courses so I can get insight from two different perspectives. Alex the Analyst YouTube. About 4 hours long video, I took notes and practiced after each “learning” sesh daily. Khan Academy. I preferred this one because I’m a hands on learner. Extras: I played SQL Island and SQLPD for more practice. Imo, Alex explained things a bit too quickly and I had to write questions on the side so I could do more digging but visuals helped. Khan Academy gave me info that Alex did not. There are more out there but like you when I initially started I was overwhelmed by the resources and I wanted to pick the right one. My advice is just pick one and enjoy the ride! Hope this helped, good luck!

A good friend of mine built this course and published it a couple weeks ago: Master SQL Basics in 7 Days . He now has 4 or 5 SQL courses including: 25 Practice SQL Questions for Beginners and 101 Practice SQL Questions: Basic to Advanced . However, I believe he is allowing students in "Master SQL Basics in 7 Days" to enroll in one of those practice courses for free. Let me know if you do enroll and I'll ask him about getting you free access to one of the practice courses.

I just started learning SQL from a youtube channel for free called CODE WITH BARA. .. till now I think the guy teaches well enough and the language is interesting as well . But I'm starting to think if i should start taking any online course as well ? specially since I'm an high school student and i really wanna develop as many skill as possible before college

In this video he teaches you now to set up a free DB where you can import data and run queries that’s what i ended up doing and asking AI to generate me interview questions based off the data i imported https://youtu.be/U-JlXWDqvco?si=jOQyUcnAidz5mBSm

Hi everyone

I would like to start learning SQL and I don't really know where to start. Can someone please describe me your journey on how you became proficient with the tool? I am working as a Product Manager, so some basic skills are definitely needed.

Thanks!

I will provide you some valuable tips to rapidly learn SQL and become a professional within few months Create your own database and practice on it. Solve SQL puzzles and challenges available online. Participate in online SQL communities and forums. Use online SQL tutorials and courses. Attend SQL workshops and webinars. Practice SQL queries on real-world datasets. Analyze and manipulate data from different sources. Create and use SQL stored procedures and functions. Work on SQL projects and collaborate with other SQL professionals. Follow best practices and guidelines for SQL optimization and performance. To get you started, I will highly recommend you look at these articles. They will guide you through : What you need to know to get started: https://link.medium.com/kz9qL7TtCAb 10 tips you should know: https://link.medium.com/NsrPQF1tCAb SQL query Optimization: https://link.medium.com/LwrtUV7tCAb Sql queries for complex business reports: https://link.medium.com/Cbi6fRbuCAb The power of sql case statement: https://link.medium.com/rY2G7UfuCAb Advanced SQL queries for mysql workbench series: PART 1: https://link.medium.com/Ab6QXnmuCAb PART 2: https://link.medium.com/mMo35opuCAb PART 3: https://link.medium.com/DXVhGKruCAb Understanding SQL inner join with practical examples: https://link.medium.com/8MYnwLtuCAb Unleashing the power of SQL aggregate functions: PART 1: https://link.medium.com/ZKZtBMAuCAb PART 2: https://link.medium.com/xpA0E7DuCAb PART 3: https://link.medium.com/7xKteHFuCAb PART 4: https://link.medium.com/zmMc91IuCAb

I would start with doing SQL bolt. Then watch either a YouTube series on SQL or do a Udemy course, I personally like Alex the Analyst's series, I recommend just starting with his basic and intermediate series. Whatever database system your company uses watch a couple tutorials on it, if it's something like MySQL or Microsoft SQL server you can set up an instance on your own computer at home and practice using it. Then start doing SQL problems on hackerrank, do them in the database system that you'll be using. Once you're at the point of being able to do all the basic stuff on hackerrank and some of the intermediate I would say you have a good starting grasp on SQL.

I recently graduated college with a minor in Computer Science but we didn't do anything with SQL. Now I'm looking at jobs and realizing its probably a good thing to add to the resume. I went through the free SQL Queries part of codecademy pretty quickly and liked it but figured I should ask for recommendations before paying any money. Looking at jobs mainly in finance now if that changes anything.

Also, I don't need it to be free, but cheap is certainly a plus.

If you want to get the hang of SQL, check out the course available at https://grzegorzpiechnik.gumroad.com/l/nnccol. There, you'll learn not only the basics but also practical tricks for handling data in databases. Creating databases, SQL queries, and even advanced stuff like joining tables - it's all right there.

https://sqlbolt.com for beginners. But after that I would encourage anyone to immediately start working on medium/hard level SQL interview questions. Unlike other coding questions, the SQL questions are actually relevant tasks and problems that companies actually encounter.

Knowing the type of problems and the thought process first will allow you to learn the syntax faster.

For someone with zero knowledge about database and sql

I tried W3echools but I think it is designed for someone who already have some knowledge about the topic and ready to practice. I’m looking for something that explains it all from the beginning.

SQLBolt.com I think works very well. Also free

W3 schools is a great start. It may feel like you didn’t get a lot from it, but it does a great job with the fundamentals. Another good introductory course is on Codecademy. The free version gets you through the beginning, but it is paid if you want to do the whole thing.

r/DataCamp on Reddit: Good places to learn SQL from? Datacamp not great

November 25, 2023 -

So I’ve been going over datacamp and have completed the intermediate sql and the course on Joins etc but recently I tried taking a test for a product firm that required SQL and most of the questions were on joins but I just scored a 12/22. Additionally I am trying to solve the intermediate questions on hackerank related to SQL and I am failing to do so. The basic ones were pretty easy.

I am wondering what resources I should look at to relearn SQL or maybe datacamp gets better as I progress? Idk. So far it seems to gloss over a lot of concepts but there is a lack of application. Or maybe I’m not very good at this and should just stick to corporate finance :/

You've described taking two of the available 32 courses. 12/22 is an exceptionally good outcome for 8 hours of training. The name intermediate might be misleading given that it is very much a fundamental course but you're still v much a beginner. I am also a beginner, even at taking Data Manipulation in SQL and two courses on PostgreSQL. Consider sticking to the end of a learning path (I.e., SQL Fundamentals, Data Analyst in SQL) in DataCamp before making a switch. Also, use the other one concurrently so you're confident it will better meet your needs. The path of least resistance when hopping around is to just stop For me, the pursuit of the perfect learning tool has been by far the biggest barrier to progress. I explore other resources

You might want to try the free SQL course from Udacity (I think it's called SQL for Data Analysis) which felt fairly solid to me. However do not under any circumstances get lured in by the paid courses or "nanodegrees". Most of their paid content is free under different course names or outdated.

I am 23 years old with a bachelors in business management and have been working as a sales development representative for about 6 months, and I hate it. Lots of down time, lots of rude prospects, the pay is laughable for someone with a degree, and it’s just something I don’t want to move up with.

I’ve always been a numbers person, so I don’t love to pivot my career to a business/data analyst. My first hurdle is learning SQL. I have minimal coding experience, so I don’t want to rely on YouTube to teach me. I also want a certification, as being 23, my resume is relatively short. Right now, I’m looking at Codecademy. Has anyone ever had experience with this site/course? Any other sites/courses I should explore?

I'm similar to you trying to learn SQL, coming from the business side. I recommend spending a day on: w3schools to learn the basic language of SQL. I learn best from case studies, real examples. HackerRank and DataLemur (I think the creator is on here) are great for those. Only after that would I try some paid courses, which I can't speak for.Good luck. Consistency is key.

I really want to get into SQL, but every website I try I have to pay after I get through the first few steps. I see a lot of people recommend YouTube, but I learn better from actually doing it myself. Does anyone know of any websites that offers SQL courses for free. Any help would be greatly appreciated.

DataLemur, LeetCode SQL, r/SQL , and SQLBolt. All pretty good resources.
