Question ID 15037

You have a Microsoft SQL Server database that includes two tables named
EmployeeBonus and BonusParameters. The tables are defined by using the following
Transact-SQL statements:

The tables are used to compute a bonus for each employee. The EmployeeBonus table
has a non-null value in either the Quarterly, HalfYearly or Yearly column. This value
indicates which type of bonus an employee receives. The BonusParameters table contains
one row for each calendar year that stores the amount of bonus money available and a
company performance indicator for that year.
You need to calculate a bonus for each employee at the end of a calendar year.
Which Transact-SQL statement should you use?

Option A

SELECT CAST(CHOOSE((Quarterly * AvailableBonus * CompanyPerformance)/40, (HalfYearly * AvailableBonus * CompanyPerformance)/20, (Yearly * AvailableBonus * CompanyPerformance)/10) AS money) AS Bonus FROM EmployeeBonus, BonusParameters

Option B

SELECT Bonus = CASE EmployeeBonus WHEN Quarterly=1 THEN (Quarterly * AvailableBonus * CompanyPerformance)/40 WHEN HalfYearly=1 THEN (HalfYearly * AvailableBonus * CompanyPerformance)/20 WHEN Yearly=1 THEN (Yearly * AvailableBonus * CompanyPerformance)/10 END FROM EmployeeBonus,BonusParameters

Option C

 SELECT CAST(COALESCE((Quarterly * AvailableBonus * CompanyPerformance)/40, (HalfYearly * AvailableBonus * CompanyPerformance)/20, (Yearly * AvailableBonus * CompanyPerformance)/10) AS money) AS Bonus FROM EmployeeBonus, BonusParameters

Option D

 SELECT NULLIF(NULLIF((Quarterly * AvailableBonus * CompanyPerformance)/40,(HalfYearly * AvailableBonus * CompanyPerformance)/20), (Yearly * AvailableBonus * CompanyPerformance)/10) AS Bonus FROM EmployeeBonus, BonusParameters
