Question

Manager | Employee  |HireDate
----------------------------------------
ManagerA| EmpA      |1/1/2012
managerA| EmpB      |1/15/2012
ManagerB| Emp C     |2/1/2012
ManagerA| Emp D     |2/15/2012
ManagerB| Emp E     |2/8/2012

每位经理的奖金金额是根据当月雇用的新兵人数计算的。恩。每位经理在第一次聘用时获得1000，每次获得500次。

它几乎就像每条记录都有种子

Manager | Employee  |HireDate   | Seed
------------------------------------------------
ManagerA| EmpA      |1/1/2012   | 1
managerA| EmpB      |1/15/2012  | 2
ManagerB| Emp C     |2/1/2012   | 1
ManagerA| Emp D     |2/15/2012  | 1
ManagerB| Emp E     |2/8/2012   | 2

和Bonus是种子的函数，为1000+（种子-1）* 500

我需要帮助生成种子。我不确定是否应该使用存储过程来生成种子或函数

最终我想生成一个表格，如下所示

Manager | Employee  |HireDate   | Bonus
-------------------------------------------------
ManagerA| EmpA      |1/1/2012   | 1000
managerA| EmpB      |1/15/2012  | 1500
ManagerB| Emp C     |2/1/2012   | 1000
ManagerA| Emp D     |2/15/2012  | 1000
ManagerB| Emp E     |2/8/2012   | 1500
