for nth highest salary problem
SELECT DISTINCT Salary FROM Employee e1 WHERE (SELECT COUNT(DISTINCT Salary) FROM Employee e2 WHERE e2.Salary > e1.Salary) = N - 1 will be the correct one since there can be multiple employees with highest salary.

Very clear explanation and target precision poin very simple way any one can understand even a person has no previous query background.

While getting employees working in same department we can use groupby instead of using alias for two tables. Whenever u use alias for a table it creates a copy of that table in RAM, which is highly inefficient if u have large table with thousands of rows.
totally agree
totally agree
But it gives us only one value when we use group by .How about others?
Thanks for explaining 👍👍

@@CodeEra2020 once in a interview I was asked to calculate 2nd or 5 th highest . At that time I was not that much aware. Then I told that we can sort them firstly in Descending order after that we can fetch 5th one. But I was not aware how I can fetch 5th record because I was not aware about limit clause. Then I watch your video.. After watching it I feel confident. But in later interview the interviwer asked me only about DML DDL commands 😁😁
Great work 😎
