🌟 Day 32 of SQL Learning Journey 🌟 Today, I tackled two exciting LeetCode problems, pushing deeper into SQL concepts: 1)Game Play Analysis IV 🎮 2)Unique Subjects by Each Teacher 📘 #SQL #LearningSQL #LeetCode #ProblemSolving #DailyLearning
Day 8 of #learningSQL 😊 Topic(s) covered 1. WINDOWS RANKING FUNCTION The Ranking functions are used to assign ranks or values to rows of data. The window ranking function must make use of the ORDER BY clause
Day 7 of #learningSQL 😊 Topic(s) covered 1. WINDOWS function 2. Calculating Running and Rolling Totals 1. WINDOWS FUNCTION Also referred to as analytical functions. WINDOWS Function performs calculations (e.g aggregation) on a specific subset of data and return a value(s)
Was bored and decided to work on a SQL task that's been on my laptop . #learningsql I created three tables for a library. One for books records, another for members records and the last for borrowing records, which contained foreign keys from books and members records.
🚨 Struggling with SQL questions? Use this simple mental model before you write a single line: 🧩 T.A.S.K. T = Tables A = Attributes (columns) S = Steps to filter/join/group K = Key logic (what are you calculating?) 🎯 Think before you SELECT. #LearningSQL #InterviewPrep
Learned about data types, SQL commands, and how to write queries for databases and tables.#LearningSQL #DatabaseBasics
Some nights it’s just me, my messy dataset, and ChatGPT whispering “we’re almost there.” This data analytics journey is teaching me more than just skills — it’s teaching me patience and power. #LearningSQL #DataAnalytics
🧠 Just wrote my first SQL Server Stored Procedure with OUTPUT parameters and started understanding CTEs (Common Table Expressions)! 💻 Slowly turning SQL from scary to satisfying 😎 #SQLServer #100DaysOfCode #LearningSQL #StoredProcedure #MicrosoftSQL
Writing a simple SELECT * FROM table feels good, But optimizing queries? That’s where the real thrill! If SQL was a person, it would be friend who always knows exactly where to find the best food (with a quick JOIN). Still a beginner, but loving every query ! #SQL #LearningSQL
Day 3 of my 30-day SQL challenge! Today I delved into JOINS and learned how to combine data from multiple tables. Excited to see how this will simplify complex queries! 💻📊 #SQLChallenge #LearningSQL #DataScience #TechJourney
Database, varchar, int, text, etc. These, and more, are the words I've added to my vocabulary. I just ran my first SQL series and the feeling is powerful. It felt just like unlocking a new language. PS: Peep the new program🤭 #LearningSQL #DataAnalytics #TechCrushHQ #TechJourney
I move again today ; Day 6 of #100DaysOfSQL Today I learned the difference between WHERE and HAVING in SQL: - WHERE filters rows before grouping - HAVING filters groups after GROUP BY` #SQL #LearningSQL
"Diving deep into SQL — mastering the WHERE clause and 7 powerful operators like LIKE, NOT LIKE, BETWEEN, IN, and more. Querying like a pro! #SQL #LearningSQL #oracleSQL
Use cases of the window Ranking functions - Top N analysis and Bottom N analysis - Generate unique ID - Identify duplicates - data segmentation That concludes day 8 of #learningSQL 😊 See you tomorrow

Starting my SQL journey!!!! For the next few weeks I will be learning SQL in public. My primary learning material be will "SQL full course for beginners- from zero to hero(30 hours)" by Data with Baraa. I'm excited about this one 😊 Let's see how it goes!!! #learningSQL
Just updated my MySQL playlist on YouTube. This new episode covers ORDER BY, sorting, LIMIT, and using DISTINCT to clean results. Simple concepts, but essential for real data analysis. Watch the update on my channel The Data Boy: youtu.be/QjIn_gf6vgg?si… #SQL #MySQL #learningsql
