1) SELECT MAX(salary) '2nd max sal'
FROM YourTable
WHERE salary < (SELECT MAX(salary) FROM YourTable)

2) SELECT TOP 1 datepart(yy, hire_date) Year, count(employee_id) cnt
FROM YourTable
GROUP BY datepart(yy, hire_date)
ORDER BY cnt DESC

[code]
Alternate approach for 1
SELECT employeeid,employeename,salary,hiredate
(
SELECT DENSE_RANK() OVER (ORDER BY Salary DESC) AS Rnk,*
FROM table
)t
WHERE Rnk=2

modified solution for 2 to take care of cases where there are ties ie multiple years with same maximum employee count

SELECT TOP 1 WITH TIES datepart(yy, hire_date) Year, count(employee_id) cnt
FROM YourTable
GROUP BY datepart(yy, hire_date)
ORDER BY cnt DESC
[/code]
