SQL数量统计问题，请教

[bigmingming]

TYPE 状态
40A 好
40B 坏
40B 好
40C 好
40A 好



现在要显示成
40A 40B 40C . 。。。。。。
好 2 1 1
坏 0 1 0
ToTal 2 2 1



注意：TYPE中类型很多，只列了3种，如何横向列出type

exec(@s)

--------------------------------------
好 2 2 1
ToTal 2 2 1



没有坏 0

希望
--------------------------------------
好 2 2 1
坏 0 0 0
ToTal 2 2 1

生成的語句格式如下：

select 
	[状态]=isnull([状态],'ToTal'),
	[40A]=sum(case when [TYPE]='40A' then 1 else 0 end),
	[40B]=sum(case when [TYPE]='40B' then 1 else 0 end),
	[40C]=sum(case when [TYPE]='40C' then 1 else 0 end)

大家都看不到吗？

[bigmingming]

谢谢大家，再问一下，如果坏的个数都是0，能否加一行 坏 个数0行的

上面各位写的行转列语句,如果坏的个数是0,它也会出来的,应该用不着另外加一行.
