Oracle's Compliance to Codd’s Rules

 

CTE (Common Table Expression) in Oracle – Simplify Your SQL Like a Pro.

Do you often write nested subqueries that are hard to read or reuse?

Say hello to CTEs – the WITH clause in Oracle that makes your SQL more modular, readable, and maintainable. Whether it's breaking down complex logic or writing recursive queries, CTEs can be a game changer.

Quick Example:
WITH dept10_emps AS
(SELECT emp_name, salary
FROM employees
WHERE dept_id = 10 )
SELECT * FROM dept10_emps WHERE salary > 5500;

✅ Cleaner logic
✅ Reusable result set
✅ Better performance tuning

Do you use CTEs in production code?
When do you prefer NOT to use them?
