Day 14/30 💻
Today was busy, and I honestly didn’t feel like doing much. 😩 But I still went back to read "GROUP BY", "HAVING" & "ORDER BY" on W3Schools for a clearer understanding.
Consistency isn’t easy, but we keep showing up! One day at a time. ❤️

Today, I studied SQL operators on W3Schools: "=", ">", "<", ">=", "<=", "<>", "BETWEEN", "LIKE" & "IN".
I also read about "ORDER BY", "ASC" & "DESC" before practicing.
Read, learn, practice! 📊 W3Schools is a great resource. Give it a try!

Today, I learned SQL "CASE" statements:
"WHEN" checks a condition, "THEN" gives the result, "ELSE" gives an alternative, and "END" closes the statement.
One step at a time! 📊✨

Day 25 of #30DaysOfSQL
I learned how powerful PARTITION BY is in SQL Server.
Unlike GROUP BY, it keeps all rows while adding totals and insights.
Example: show each employee’s salary + total salary of their department
Day 9 of my SQL Journey 💻
Hi #datafam, so today I decided to face my subquery fear and I started getting the hang of it. Subquery makes breaking down complex queries less scary
What’s your favorite SQL trick for handling tricky queries?

🧵 Day 1 of my #30DaysOfSQL Journey
Today I learned “Introduction to Databases & SQL.”
A database = organized collection of data.
SQL (Structured Query Language) = the language used to talk to databases.
Rules to remember:
Both queries must return the same number of columns
Data types must be compatible

Day 20 of #30DaysOfSQL Set Operators in SQL Server
Sometimes, you need to compare results from 2 queries. Instead of joins, SQL gives us Set Operators
Let’s break them down 🧵

It's day 30 of my 30 day SQL learning challenge, and it's been quite a journey. From struggling to import datasets into SQL Workbench and facing errors to mastering joins, subqueries, CTEs, and complex SQL functions that challenged my life choices.
Day 17 of #30DaysOfSQL LEFT JOIN vs RIGHT JOIN
What if you want all rows from one table
(even without a match)?🧵
🍋 Turning Lemons to Lemonade
Missed 4 days of my #30DaysOfSQL challenge. Work + Cider + DataCamp = overwhelming.
But… small wins still count. Progress isn’t perfect, it’s persistence. Back on track & ready to keep building.
