Great site that guides you in learning and practicing SQL

Very good course for those who doesn't not very much about sql

There are a lot of courses that go in-depth . For a beginner like me it makes me happy that I have a plethora of options to choose from. You can start at a beginner's course, or go straight to advanced if you would like.

More confusing than it needs to be. Queries take forever to execute. Data in database does not always match with the expected output. A complete waste of my time. LearnSQL.com does not teach best practices when querying data and it's ridiculously obvious. I spend more time attempting to figure out the poorly worded exercises than I do learning SQL.

one of the best SQL tutorials I have ever taken

This one of the great learning management system have ever seen, practice as you learn

Progressive and interactive. Basic notions are reviewed and advanced concepts are very well explained (CTEs, recursive requests). Yet it would have been better to have the same panel of exercices whatever the country. But as I said, learning is very efficient. Often, there is a great lifetime discount. Many new exercises each month. So don't hesitate.

This has been an excellent source of learning by practice for me. I am still half-way learning through different aspects of SQL, but so far I have enjoyed the clarity and content of different courses. Thanks

Step by step upgradation of level of difficulty and lucid datasets make learning a great experience. Also the help guides in case you are stuck anywhere

It's free for those who have a student email, interactive and helpful.

This honestly is the best platform to learn SQL. Provided you are eligible for their student promo, I would say this is the best site. However, if you are thinking to spend money on this course, I think there are better alternatives. You basically pay this website for ease of use (organized lessons/exercises/certifications) that you would otherwise spend a good amount of effort on if you do it by yourself.

I'm thrilled to have discovered LearnSQL.com, which has become my go-to online resource for SQL documentation and real-world applications over the past year.

As I've been interviewing for Data Analyst roles, I've noticed a consistent pattern in SQL interview questions. These questions typically fall into two categories: testing everyday SQL functions (such as JOINS, CTEs, and WHERE clauses) and applying SQL to real-world metrics.

While I've found resources for everyday SQL functions, it's been challenging to find reliable and reproducible solutions for applied metrics problems, which are common on coding testing sites like Leetcode.

Ex.
- Mapping hierarchies
- Running totals
- Moving Average
- % of total

That's where LearnSQL.com has been a game-changer, it has both kinds of problems

Over the past year, I've successfully solved over 10 Leetcode problems and passed more than 5 SQL coding challenges from companies like TikTok, Google, and various startups.

LearnSQL has a great collection of hands on exercises to learn SQL.

LearnSQL.com is a great way to learn SQL in my opinion. There are many hands-on exercises to practice your skills and a lot of courses to choose from. I would highly recommend this platform for learning SQL.

So I am someone who does not have a formal developer background, but I learned the importance of working with databases for my no-code automations, as well as implementing AI into my current business.

So, I needed to find a way to learn SQL in a way that was accessible for me and something that I could apply right away to my business. And I couldn't afford to spend thousands of dollars in order to become proficient. I was on a tight budget. I investigated close to 10 different sources in order to learn SQL. I did a course on Udemy, I got numerous Kindle eBooks, I looked at YouTube videos, I even started taking a course on FreeCodeCamp. I looked into some other formal trainings and I even started taking a course on FreeCodeCamp.

I would definitely say that LearnSQL stands out in what it offers for my particular needs.

1. The price is almost unbelievable.
- They offer all of their courses for such an affordable price because I signed up for the discount. It was almost too good to be true that all of those courses were available for one low price.

2. You don't need to set anything up to learn.
- You don't need to host a database or have your own data or anything. They give you data to work with right away and a user interface where you can just jump right in and start writing queries.

3. It gets right to the point.
- It teaches you how to write the language and you'll know how to write queries within minutes of starting your first course.
- The cheat sheets that they have that go along with it are amazing.

4. It's definitely easy to follow and it's all about application.
- There is no fluff and you're not going to spend any time learning theory without writing queries right away to see how it applies.

5. They have all of their courses nuanced for any particular popular SQL server configuration.
- Whether it's Postgres, MySQL, or whatever server you are using, LearnSQL makes specific courses available to you.
- I love how they have courses on creating reports and data analysis/data science focused courses, which show you which functions in SQL are relevant to different use cases.

6. They teach everything very progressively.
- You learn what you need to do first to build on top of each other. It gets really advanced as you keep going.
- Concepts like window functions and CTEs are introduced in a manner that makes them easy to understand and apply.

7. Accessibility across devices.
- I loved that I could use it from my tablet, phone, or computer. It's web-based, so you can log in from anywhere.
- This was really helpful for me because I like working from my tablet at night so I don't have to sit in front of my computer screen.

8. Option to get hints or answers.
- If you need hints or the answer for your particular situation, you have the option to ask the system.
- Whether you prefer to solve problems on your own or need a little help to move forward, the system accommodates both learning styles.

Quick tip: I used ChatGPT alongside the course to look into certain concepts further and find me YouTube videos for additional learning. (Some of which were from the LearnSQL YouTube channel!)

10. Additional resources and trusted source.
- Because I knew them as a trusted source, I was able to glean a lot of wisdom from their cookbooks, blogs, and cheat sheets.

As far as things I would like to learn more of, it would be nice if they had courses on how to set up servers and manage databases at that level. I didn't have any experience with that when I started, and they did a good job of teaching SQL. It would have been beneficial if they also covered server setup and database management.

Disclaimer: I cannot say I went through every lesson of all courses. I didn't notice them teaching that stuff in the descriptions, but it's possible it's in there because they have so many different courses available.

Anyway, I hope this review was helpful to you. If the sale is going on, definitely swoop it up. It's been so nice to just be able to jump into it whenever I need answers on the go even.

easy to learn with practice

I really enjoyed this course. I practise a lot and expose to a lot.

I took the SQL Basic course which is available for free for students. I found the course very well organized and one of the best online courses.
Even though the course is named SQL Basic it covers some advanced concepts such as grouping, joins, and subqueries.
The course starts with the fundamentals of SQL and gradually covers complex topics.
There are a total of 129 exercises that resemble real-world scenarios.
I am very happy about what I have learned from learnsql.com and I would recommend everyone passionate about learning SQL to try this course especially if you are a student since this course is freely available to you.
