數(shù)據(jù)表Order.dbo結(jié)構：
OrderNo varchar(10), ---單號
GetDate Varchar(10), ---日期
Sales Varchar(10), ---員
ItemNo Varchar(20), ---產(chǎn)品號
Amount Smallint ---金額

數(shù)據(jù)記錄如下：
001 2004-01-01 ABC A001 1000
001 2004-01-15 QQQ A001 5000
002 2004-02-01 ABC A001 2000
003 2004-03-01 ABC A001 3000
004 2004-06-01 ABC A001 6000

要求輸入欲查詢的年度條件如：2004，得到按月份統(tǒng)計的如下結(jié)果：
Slaes 200401 200402 200403 200404 200405 200406 200407 200408 200409 200410 200411

QQQ 5000

第一種答案：

declare @sql varchar(8000)
set @sql = 'select Sales'
select @sql = @sql + ',sum(case left(GetDate,7) when '''+left(GetDate,7)+''' then Amount end) ['+ replace(left(GetDate,7),'-','')+']'

from (select distinct left(GetDate,7) as GetDate from test) as a
select @sql = @sql+' from test group by Sales'
print @sql
exec(@sql)

第二種答案：

SQL語句:
select
sales as '業(yè)務員',
sum(case when month(getdatetime)=1 then amount end) as '1月份總額',
sum(case when month(getdatetime)=2 then amount end) as '2月份總額',
