📊 𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄𝗲𝗿: How do you find Duplicate Records in a table? 🙋‍♂️ 𝗠𝗲: Use GROUP BY with HAVING to filter rows occurring more than once:

SELECT column_name, COUNT(*) AS duplicate_count
FROM your_table
GROUP BY column_name
HAVING COUNT(*) > 1;

🧠 Logic Breakdown: - GROUP BY column_name groups identical values - HAVING COUNT(*) > 1 filters groups with duplicates ✅ Use Case: Data cleaning, identifying duplicate user emails, removing redundant records 💡 Pro Tip: To see all columns of duplicate rows, join this result back to the original table on column_name. 💬 Tap ❤️ for more!

📊 𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄𝗲𝗿: How do you get the Employee Count by Department in SQL? 🙋‍♂️ 𝗠𝗲: Use GROUP BY to aggregate employees per department:

SELECT department_id, COUNT(*) AS employee_count
FROM employees
GROUP BY department_id;

🧠 Logic Breakdown: COUNT(*) counts employees in each department GROUP BY department_id groups rows by department ✅ Use Case: Department sizing, HR analytics, resource allocation 💡 Pro Tip: Add ORDER BY employee_count DESC to see the largest departments first. 💬 Tap ❤️ for more! --- If you want, I can continue creating the next 5 posts in this same style for SQL interview tricks. Do you want me to do that?

📊 𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄𝗲𝗿: How do you find Employees Earning More Than the Average Salary in SQL? 🙋‍♂️ 𝗠𝗲: Use a subquery to calculate average salary first:

SELECT *
FROM employees
WHERE salary > (
  SELECT AVG(salary)
  FROM employees
);

🧠 Logic Breakdown: - Inner query gets overall average salary - Outer query filters employees earning more than that ✅ Use Case: Performance reviews, salary benchmarking, raise eligibility 💡 Pro Tip: Use ROUND(AVG(salary), 2) if you want clean decimal output. 💬 Tap ❤️ for more!

📊 𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄𝗲𝗿: How do you find the Third Highest Salary in SQL? 🙋‍♂️ 𝗠𝗲: Just tweak the offset:

SELECT DISTINCT salary
FROM employees
ORDER BY salary DESC
LIMIT 1 OFFSET 2;

🧠 Logic Breakdown: - OFFSET 2 skips the top 2 salaries - LIMIT 1 fetches the 3rd highest - DISTINCT ensures no duplicates interfere ✅ Use Case: Top 3 performers, tiered bonus calculations 💡 Pro Tip: For ties, use DENSE_RANK() or ROW_NUMBER() in a subquery. 💬 Tap ❤️ for more!
