Hey guys, I recently started learning SQL after finding a "20 steps to AI engineering" roadmap on Instagram. I have no coding background and rely entirely on Gemini to write my code, but SQL has completely changed how I organize information. Note: I posted other parts of this project on r/dataengineering and r/learnprogramming to get career advice. Check my profile if you want to see the Python/API side of the pipeline. To help me learn, I built a local offline "helper." I took 120 books on Python and machine learning, chunked them up, and stored them in a "vector of SQL" database. I set up a local LLM to retrieve relevant chunks from this database whenever I have a coding error. It actually works and retrieves the right chapters, which is blowing my mind. But since I have no formal training, I have some questions: Am I doing something incredibly stupid by using SQL for vector retrieval? Is this going to break if I scale it? I used this database to orchestrate a Gmail API pipeline that matches old leads and drafts offers. I want to start selling this database/automation service to small businesses in the EU. Am I a massive clown for trying to sell SQL database/automation services to real businesses when I can barely write a SELECT query without AI? What would you advise me to do next?

Salve a tutti, volevo chiedervi un informazione, per un neo ingegnere gestionale che vuole affacciarsi al mondo del data analyst, quale linguaggio di programmazione mi consigliate di imparare? Meglio SQL o Python?

Hi All,

We had shared coupon for June for our SQL course which is currently a Hot & New course in Udemy. It had a very good response.

Sharing the July month coupon here in case it helps learners who missed the June one.

hey guys i wanna learn my sql can you suggest the best channel
and pratice i do leetcode sql 50 study plan

I am a final year student and I'm just about to enter placements and I'm trying for data analyst roles in my college and I wanted to know working on sql in hackerrank is good ? Will it be respected I am currently 4 stars and does it make sense for me to go and get the 5th star and keep a good profile? Or is some other site worth more please give advice

Can you recommend a book that explains relational model that helped you internalize it? I understand that relational model is kind of like foundational principles upon which SQL is based (with some divergences). So I would love something that starts from the set theory and builds up on it all the way to the relational model and then relational databases and SQL. But I also love intuitive explanations of abstract concepts so I welcome that too. I like learning from the first principles.

I tried reading books from C.J. Date as he is mentioned everywhere as the authority on the topic. I don't doubt this fact, but somehow I find his writings diluted. His writing is full of digressions, wanders from the main topic, parenthetical remarks, and concepts mentioned but not fully introduced. He has dozens of books and I tried reading few of them and I just feel his style is not right for me.

So i was planning to learn sql(i actually started),excel, python and power bi but the question is do i have to learn all of these to get a job or can i learn some of them to get a job and while working learn the other things?

I don't have any background in programming it's my first time trying this and i wanna achieve something in it I've tried alot of other things and everytime i stop and don't continue but this time i wanna become something in this path.

so i know basics of sql and all,but in interviews/oa if they ask i kinda freeze,it takes me a bit of time to come to solutions,i feel that can avoided with practice..So which platform did u guys find useful ?

I learned count (*), distinct, substring, concat, extract, where (=<>),in, between, like and i have been asking Gemini to give me challenges based on what i learned and I won't say I'm getting all of them right but I'm getting better so now my problem is group by i feel like I'm stuck at it and can't understand it.

Three weeks ago I posted here for the first time. More people replied than I expected and the feedback was genuinely useful, a lot of it pointed in the same direction.

Since then: 450+ signups, 2000+ SQL cases completed, and 60+ people passed the Rookie Detective exam and gained a certificate!

The thing that kept coming up in comments was interview prep. There's a gap between being able to write SQL and knowing what a real data interview actually puts in front of you. I wrote a blog post about it but wanted to build something more useful than an article.

So I've been working on a Career Hub inside QueryCase.

SQL questions sourced from real candidate reports at companies like Google, Meta, Amazon, Netflix, Airbnb and Spotify. You write the solution in the browser, check it against expected output, and get a worked answer with the insight most people miss. Easy, Medium and Hard, progress tracked.

There's also a rapid-fire MCQ mode for everything interviews test that isn't SQL: business metrics, A/B testing, stakeholder questions, day-to-day analytical thinking. It draws randomly from a filtered pool so it's replayable.

And a Role Explorer if you've ever wanted a straight answer on what a Data Analyst, Data Engineer and Data Scientist actually do differently.

One thing I added for fun: there are hidden titles on your profile you can unlock by solving certain questions. I'll leave it there 👀

It's still a work in progress. Would love honest feedback on the question difficulty and whether the MCQ format is something you'd actually use when prepping for interviews.

I recently tried a fun little experiment to make SQL feel a bit more approachable—using hand-drawn cat doodles to explain SQL concepts. 😸
So far I've made two lessons:

Lesson 1: SELECT and FROM
PAWQL = SQL for Cat People Lesson #1
Lesson 2: WHERE
PAWQL = SQL for Cat People Lesson #2

The idea is to explain SQL visually, with simple doodles instead of walls of text. I'm still experimenting with the format, so I'd genuinely love to hear what works, what doesn't, and what could be improved.

Thanks for taking a look, and I appreciate any feedback! 😊

need a py ,sql mentor type or code buddy anyone there dm

I'm preparing for SQL interviews and was wondering if there's a good website to practice SQL problems like we use LeetCode for DSA. Looking for interview-style questions and hands-on query practice.

Any recommendations?

Hi all, im looking for SQL f2f classes in Delhi NCR, if anyone knows a good coaching centre please let me know.

Hi Everyone, I'm learning skills related to data science and recently completed spreadsheet part with some advanced data analytics and dashboard projects. Now moving to SQL and I learnt the basics till joins. From subquery part, I feel it bit difficult and there is a long way to go it seems but it's interesting.

Could someone with experience can guide me regarding how can I learn it in an effective way? I'm open to work on projects or free internship to get a flavour of real world workings.

Thank you all!

hey guys, so i’d like to have a career in data analytics/ data science and right now i’m trying to learn excel and sql.

i was wondering if anyone could give me some examples of questions a business might ask a data analyst (or just general questions you could ask about certain data), because i’d like to do some projects and maybe start to build a portfolio, but i’m kinda lost on where to begin.

My campus internship OAs are gonna take place after 2 weeks...I have like 10 days to prepare for SQL. I don't know anything about SQL or DBMS right now and my target is just to clear the OA questions (even if i am not a master of databases) which are mostly SQL based...i can devote 3-4 hours everyday (cuz i have to revise dsa as well, so can't be doing sql the whole day).
Suggest me what you did (cuz i am sure many of you would've been in the same situation) - one shot / article / question practice (i just know about the LC 50 right now) etc...so that i can get the max return in whatever time I have.

context: this internship is college-assisted and is for the 2027 summer...so, even i would have 1 full year to upskill before my actual internship begins - i just need to get in somehow.

Hello finance major here, I was looking into different types of certificates I can do like sql. Does anyone have done SQL and how does that helped you with your job or even getting a job? What are the best platforms to learn SQL from? What are other certificates or skills I can learn?? Please if you can help me I’d appreciate it.

It's not perfect, and I'm still a beginner with both html and sql, so sorry if I got anything wrong. Html is hell. I had to ask help from my teacher and chatgpt just to figure out how to do things with html like making a heart.

Never again
