• select count(distinct) employees where salary > (select max(salary) from employee); This is used when we want to find out how many people have higher salaries than our maximum salary employee’s or if someone has a very high salary then what is his name?
• select a.* where b.id = c.id; To find out if an employee has been assigned any project or not using foreign key constraint

Another way is : Select max(Salary) from Employee where Salary not in (Select max(Salary) from Employee); Here, we will get maximum salary from the table and then exclude that highest salary getting second highest salary.

One more way is : Select max(Salary) from Employee where Salary not in (Select max(Salary) from Employee); Here, we will get maximum salary from the table and then exclude that highest salary getting second highest salary.

This is a good way to find the second highest salary in sql

The third way to find second highest salary in SQL is:

There are different ways to find Nth Highest element in a table using SQL.

There are different ways to find Nth Highest element in a table using SQL.

The first method is to use the MAX() function and then check whether any employee has a higher salary than the maximum value. If so, you need to return its name as it is one of the highest paid employees in your company.

SELECT max(salary) from employee where salary not in(select max(salary) from employee);

You can also use the ORDER BY clause followed by an OFFSET clause:

SELECT salary FROM Employee ORDER BY Salary DESC LIMIT 1 OFFSET 1;

This will give you all employees whose salaries are equal or less than that of their second highest colleagues’ salaries

Conclusion

The third query is the most preferred out of all as it gives an error if there are less than 2 records in Employee table unlike the first and second queries. Though, all three queries work equally well when we have more than 1 record in Employee table.
