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.

Yup, you can learn SQL for 100% free on DataLemur: https://datalemur.com/sql-tutorial

r/SQL on Reddit: Unemployed. Need free resources to learn SQL

June 19, 2024 -

Hi all. I'm recently unemployed and mostly savvy with Excel. What are some free resources that offer some structured learning. Is there anything like Khan Academy for SQL that is free? Really wanting to enroll in a degree program eventually, but what are good resources to start with for the time being?

r/learnSQL https://cs50.harvard.edu/sql/2024/ a structured way of learning SQL and it's free. Only the certificate costs money. If you want to challenge yourself also free is https://www.edx.org/bio/jennifer-widom Do all the courses starting with This one , it is not easy but rewarding. Also before starting either CS50 or Widom consider https://selectstarsql.com/ and https://sqlbolt.com/ first. And if either CS50 or Widom's courses still seem very challenging I want you to go through this https://www.pg4e.com/ . It will teach a lot of practical hands on use of databases vs just exercises. All of this helps with repetition. Trust me I know, I'm unemployed right now too and I did a few courses (that repeated material) and then interview problems which boosted my mastery with SQL. Once you've done either CS50 or Widom I want you to go through https://datalemur.com/blog/sql-interview-guide and https://datalemur.com/sql-tutorial . Again this is all about repetition and saying the same material presented in different ways. Once you finish with the Data Lemur advanced section https://www.windowfunctions.com/ go through that site and everything you have to look up, look up on Youtube some short video on each section. https://downloads.yugabyte.com/marketing-assets/O-Reilly-SQL-Cookbook-2nd-Edition-Final.pdf grab a copy of that (yes this is legal, it's provided by a company) And go through it. https://pgexercises.com/ eventually get to a point where you can do all the exercises here with minimally looking things up. Once you can do everything on PGExcercises get on DataLemur and do the SQL practice interview problems. All of this should have cost you a grand total of $0.

Here are some websites : SQLZoo - https://sqlzoo.net/wiki/SQL_Tutorial SQLBolt - https://sqlbolt.com/ MySQLTutorial - https://www.mysqltutorial.org/ SQLServerTutorial - https://www.sqlservertutorial.net/ SQLiteTutorial - https://www.sqlitetutorial.net/ SQLPractice - https://www.sql-practice.com/ LearnSQLOnline - https://www.learnsqlonline.org/

r/SQL on Reddit: best free site to practice SQL while learning for a total beginner

January 10, 2024 -

hi friends, i have decided to shift careers to data analysis, so i need to master SQL.

i have ZERO IT background, and i need to apply whatever i learn early on.

so, i need a free and efficient site, easy to use, to practice SQL while learning it.\

what are your suggestions?

https://www.w3schools.com/sql/ is a good place to start.

Datalemur's SQL tutorial and w3schools SQL tutorial. They both explain the concepts and give you the opportunity to practice the concept with practice problems. I didn't have any experience in SQL, but during winter break I used both of these resources to learn and they teach the syntax and concepts very well and quickly. I can already do basic-intermediate queries.

Specifically using it to query company data in different Salesforce CRMs from altered software.

https://sqlbolt.com is great to get acquainted with the basic syntax. Don't make it a challenge though. If you get stuck just check the answer, fill in the answer (muscle memory) and come back later to see if you can remember it. The reason you should be rushing through this fast without any concern whether you understand it or not is because you'll learn SQL faster if you learn it top-down. Which means exploring the problem first, establishing how it needs to be broken down, and then finally at the end enter the syntax. And that's when job interview problems (start anywhere on Youtube) are awesome, they're all derived from real world databases. They all will walk you through this process the right way. People who start trying to get a perfect syntax first will be treading water for a long time before they get to chew on what makes SQL so satisfying to work it. That's what I did and I wish someone had told me this. Instead I had SQL for Dummies starting me out on database sanitation...

Just be careful with YouTube. There are a lot of channels that teach enough so you learn something but leave out crucial info to drive traffic elsewhere using "helpful" links in the description.

r/SQL on Reddit: Best way to learn SQL

March 13, 2023 -

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.

r/SQL on Reddit: Best resources to learn SQL and what should I focus on to get a job?

September 28, 2023 -

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 (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.

I am an analyst and want to learn more about sql seems to be industry standard but I have never had to use it?

Are there free sources or courses I can follow? And do they offer programs for me to test while I progress?

You can take your time and get this done in about a few days to a week easily. It’s very to the point, which I appreciated. https://sqlbolt.com Also, download https://sqlitestudio.pl and open it up. Create a database, create a table, and import a CSV file and play around with the data either as your doing the tutorial or right after. Next step: http://kevinluo.net/books/book_SQL%20Queries%20for%20Mere%20Mortals%20-%20John%20L.%20Viescas.pdf Edit: if the book link above does not work try this one (or type "SQL Queries for Mere Mortals" into PDF Drive ): https://www.pdfdrive.com/download.pdf?id=199786077&h=281e7d1eafff5652256f831775c5cc5c&u=cache&ext=pdf

Graduating college in December with a Finance degree. I’ve talked to multiple people in the field I want to work in and they all recommended learning SQL. I’ve never coded in my life but I promised my mentor that I will learn. Any recommendations on how to self teach myself for free? Any Youtube accounts, websites, etc that will help me? Thank you!

W3schools.com Codecademy Sololearn Alextheanalyst Adam Finer This is more than enough to get you going. Learn the fundamentals, and you'll be fine. SQL is imo the easiest form of coding to learn. It's not really a programming language, but it'll give you a brand new perspective. Stay focused, and don't be afraid to fail. You'll get the hang of it before you know it. Good luck!

I was in the same boat before I got a card services analyst job in june. since January I spent a lot of time every night learning sql, first on w3 schools, although a lot of the examples are hard to follow at first because knowing how statements were structured and what the tables meant took a while for me to grasp. Still really good information. After that I spent a lot of time on SQLbolt and SQLzoo practicing different queries. Once I got to that point I had a solid understanding of how SQL worked. that all helped me land the job. Now, I run queries at my job and it’s amazing

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! 🙌

Hi, the website I used is https://www.sqlservertutorial.net/ , what also helps is to have a roadmap so you can know where you are and what information to target. All the best

r/learnSQL on Reddit: What is the best way of learning SQL and databases in general?

July 16, 2025 -

I am a backend software developer with around 2 years of professional experience. I create and maintain CRUD web apps on a daily basis, so SQL and databases are no strangers to me. I would like, though, to go deeper and learn those topics better. I was thinking of reading the whole MySQL documentation. But I am also considering the SQLite official documentation, as it seems to be written better (they provide well prepared graphics for a lot of concepts, despite the text). What do you think of that approach to learning? Would you recommend that or there are better ways to dive deep?

I was thinking of reading the whole MySQL documentation. the fact that you even considered this is a good sign "da manual" is muchly underappreciated

In my case I learned because of work requirements, data migrations, etl, complex reports.

January 15, 2026 -

Not a data scientist, I am a risk professional who probably needs to know a little more than the basics. Do any certificates standout from the rest as being more legitimate?

For beginners, freeCodeCamp and SQLBolt are solid and genuinely beginner-friendly. Mode SQL tutorials are also great once you know the basics, especially for analysis-style queries. For your use case, focus on SELECTs, JOINs, GROUP BY, window functions, that’ll cover most real work. Certificates don’t matter that much in practice. They can help with structure or confidence, but employers care way more about whether you can actually write and explain queries. If you do get one, treat it as learning, not a signal

Hi people. I need to prepare ASAP for a programming test for a particular role. For this I need to learn SQL asap. I don't need advanced expertise. Just basic proficiency is enough. Where and how do I start?

sqlbolt.com
w3schools.com/sql
sqlzoo.net

Install SSMS and import a database, then start writing queries and asking it questions. Group by, etc. It really isn't that hard if you have a programming background. Joins are a little weird, and NULL's have some weird behaviors, etc. but as far as basic proficiency it shouldn't take more than a few hours of working in a meaningful context.
