这个sp怎么写呢？

[Lansie]

有一张表(tbcourse)，如下
id type time
1 mat 2006-1-1
2 chm 2006-1-1
3 chm 2006-1-1
4 eng 2006-1-1
5 eng 2006-1-1

一个sp,如下
select type，count(*) as sum from tbcourse group by type
得到
mat 1
chm 2
eng 2
现在的问题是领导要求把mat表示成成‘数学’，chm表示成‘化学’，eng表示为‘英语’
该怎么办呢？

麻烦各位指点一下

[sdsxlj]

select case type when 'mat' then '数学'
when 'chm' then '化学'
when 'eng' then '英语',sum from (select type，count(*) as sum from tbcourse group by type) t

[paoluo]

select (Case type When 'mat' Then '数学' When 'chm' Then '化学' When 'eng' Then '英语' End) As type, count(*) as sum from tbcourse group by type

[sdsxlj]

select case type when 'mat' then '数学'
when 'chm' then '化学'
when 'eng' then '英语' end,sum from (select type，count(*) as sum from tbcourse group by type) t

[hrb2008]

create table test
(
type varchar(10),
name varchar(10)
)
insert into test
select 'chm','化学' union all
select 'mat','数学' union all
select 'eng','英语'
go
select a.id,a.type,a.time,b.name from a inner join b on a.type = b.type

对了想问一下
select case type when 'mat' then '数学'
when 'chm' then '化学'
when 'eng' then '英语' end,sum from (select type，count(*) as sum from tbcourse group by type) t

最后那个t什么意思？

[paoluo]

t是別名
