稍微复杂数据横竖倒置显示的方法

[Eric1006]

数据格式如下：

月份 产品 产品出售个数 产品出售金额 产品结算金额
201101 水笔 8 80 70
201101 圆珠笔 6 40 35
201101 钢笔 10 90 88
201102 水笔 10 90 60
201103 圆珠笔 7 60 38
201104 钢笔 13 110 109

需要将该数据格式转为
月份 水笔出售个数 圆珠笔出售个数 钢笔出售个数 产品出售总金额 产品出售总结算金额
201101 8 6 10 210 193
201102 10 7 13 260 207

SQL语句该如何编写？谢谢！

select 月份, max( case when 产品='水笔' then 产品出售个数 end)[水笔出售个数],
max( case when 产品='水笔' then 产品出售个数 end)[圆珠笔出售个数],
max( case when 产品='水笔' then 产品出售个数 end)[钢笔出售个数],
sum(产品出售金额) [产品出售总金额],sum(产品结算金额) [产品出售总结算金额]
from tb group by 月份

201102好像只有水笔

不明白lz的具体意思，猜测了两种

use tempdb;
/*
create table tb
(
	月份 nvarchar(10) not null,
	产品 nvarchar(10) not null,
	产品出售个数 int not null,
	产品出售金额 int not null,
	产品结算金额 int not null
);
insert into tb([月份],[产品],[产品出售个数],[产品出售金额],[产品结算金额])
values
('201101','水笔',8,80,70),
('201101','圆珠笔',6,40,35),
('201101','钢笔',10,90,88),
('201102','水笔',10,90,60),
('201103','圆珠笔',7,60,38),
('201104','钢笔',13,110,109);
*/
--语句1
