*✅ Advanced SQL (Subqueries & CTEs) 🗄️🔥*
👉 Now we move to advanced SQL concepts heavily used in:
✔ Data Analysis
✔ Reporting
✔ Dashboards
✔ Interviews
*🔹 1. What is a Subquery?*
A subquery is a query written inside another query.
👉 Also called:
✅ Nested Query
*🔥 2. Example of Subquery*
👉 Find employees earning above average salary.
SELECT name, salary
FROM employees
WHERE salary > (
SELECT AVG(salary)
FROM employees
);
*How it works:*
1️⃣ Inner query calculates average salary
2️⃣ Outer query filters employees
*🔹 3. Types of Subqueries*
✔ Single-row subquery
✔ Multiple-row subquery
✔ Correlated subquery
*🔹 4. Correlated Subquery ⭐*
👉 Inner query depends on outer query.
SELECT e1.name
FROM employees e1
WHERE salary > (
SELECT AVG(salary)
FROM employees e2
WHERE e1.department = e2.department
);
*🔥 5. What is a CTE?*
CTE = Common Table Expression
👉 Temporary result set used inside a query.
Defined using:
WITH
*🔹 6. Example of CTE ⭐*
WITH avg_salary AS (
SELECT AVG(salary) AS avg_sal
FROM employees
)
SELECT *
FROM employees
WHERE salary > (
SELECT avg_sal FROM avg_salary
);
*🔹 7. Why Use CTEs?*
✔ Makes queries readable
✔ Simplifies complex logic
✔ Easier debugging
*🔹 8. Difference Between Subquery & CTE*
*Subquery* : Nested inside query
*CTE* : Defined separately
*Subquery* : Harder to read
*CTE* : More readable
*Subquery* : Repeated logic possible
*CTE* : Reusable
*🔹 9. Why This is Important?*
✔ Frequently asked in interviews
✔ Used in dashboards & analytics
✔ Important for real-world SQL projects
*🎯 Today’s Goal*
✔ Understand subqueries
✔ Learn correlated subqueries
✔ Understand CTEs
✔ Write cleaner SQL queries

I repeat my tools/project are inspired from me trying to do something with third-party tools/project and i couldn't
This is me always challenging myself
Repost from JMWhatsApp Updates
Someone asked me today whether JMWhatsApp Ultra is still active. The answer is YES.
I have always maintained a simple philosophy: JMWhatsApp Ultra is not designed to work for just a few individuals while the majority experience issues. Our goal is for it to work seamlessly for the vast majority of users, if not everyone.
At the moment, the main challenges are the inability to link accounts and the logout issue. The team is actively and efficiently working to resolve both problems as quickly as possible.
We understand that the process is taking longer than many expected, and we are fully aware of the concerns. However, significant progress is being made behind the scenes, and we remain committed to delivering a stable and reliable experience for all users.
Thank you for your patience and continued support.
