如何在日期显示表值

表1 

ID period fromdate todate Value

001 01/2012 02/01/2012 10/01/2012 AB
002 01/2012 05/01/2012 18/01/2012 AL
....

从上表中，我想显示明智的输出。

ID，期间应该从table1创建，然后剩余天数列应该从期间生成..

日期列应根据期间

创建

例如

01/2012 means - 31 days column
02/2012 means - 29 days column
04/2012 means - 30 days column

我想从table1

显示值明天

预期产出

id period 1 2 3 4 5 ...10 11 12 ..18 19 ....31  total (Column Header)

001 01/2012 N AB AB AB AB .... AB N N.... N  31
002 01/2012 N N N N AL....AL AL AL...AL N .....N 31

AL，AB应与table1匹配，剩余列应显示为N，total表示特定月份的总天数。

如何在sql server中执行此操作。

查询帮助期待...

您需要将日期格式调整为您的语言环境，但我使用SQL 2000（美国日期格式）：

create table Table1 (id varchar(3), period varchar(10), fromdate datetime, todate datetime, value varchar(2))
go
insert into Table1 values ('001','01/2012','1/2/2012','1/10/2012','AB')
insert into Table1 values ('002','01/2012','1/5/2012','1/18/2012','AL')
insert into Table1 values ('003','02/2012','2/10/2012','2/12/2012', 'DA')
go

select id
, period
, [1]=case when DATEADD(dd,0,left(period,2)+'/01/'+right(period,4)) between fromdate and todate then value else 'N' end
, [2]=case when DATEADD(dd,1,left(period,2)+'/01/'+right(period,4)) between fromdate and todate then value else 'N' end
, [3]=case when DATEADD(dd,2,left(period,2)+'/01/'+right(period,4)) between fromdate and todate then value else 'N' end
, [4]=case when DATEADD(dd,3,left(period,2)+'/01/'+right(period,4)) between fromdate and todate then value else 'N' end
