Q4. Diffence between correlated and non correlated subquary?
Ans. 
Correlated subquery refers to a subquery that is dependent on the outer query, while non-correlated subquery can be executed independently.
• Correlated subquery is executed for each row processed by the outer query, while non-correlated subquery is executed only once.

• Correlated subquery is slower in performance compared to non-correlated subquery.

• Example: SELECT * FROM table1 WHERE column1 = (SELECT MAX(column2) FROM tab
