Final answer:
To find the second highest salary in SQL, you can use the MAX function and the SELECT statement.
Step-by-step explanation:
In SQL, you can find the second highest salary by using the MAX function and the SELECT statement. Assuming you have a table called Employees with a column called Salary, you can use the following query:
SELECT MAX(Salary) FROM Employees WHERE Salary < (SELECT MAX(Salary) FROM Employees);
This query will return the second highest salary from the Employees table. It does this by first finding the maximum salary and then searching for values less than that maximum.
