Answer-Which of the following SQL queries is used to find the second highest salary from an employee table?...

Question

Accepted Answer

The query uses a nested SELECT statement to retrieve the second-highest salary from the employee table. Lets break it down    Inner query SELECT MAXsalary FROM employee retrieves the highest salary in the employee table.   Outer query The WHERE salary  SELECT MAXsalary FROM employee ensures that only those salaries smaller than the highest salary are considered, and the outer MAXsalary retrieves the largest salary from that set, effectively giving the second-highest salary.    Why other options are incorrect    B is incorrect because the query does not return the highest salary but rather the second-highest salary by excluding the maximum salary.   C is incorrect because nested SELECT statements are valid in SQL and do not cause errors here.   D is incorrect because the query will return a value unless there are no records in the employee table.   E is incorrect because the query will return a single valuethe second-highest salary.
