sqlserver 如何统计五年内的数据和

都是日期型数据的话

SQLServer2008 数据查询 累加问题

select x.BFactoryName,x.LineName,x.Month,y.BaseValue,x.CurValue,x.TotValue

from (

select b.BFactoryName,b.LineName,a.Month,--c.BaseValue,

sum(case when a.Month=b.Month then b.MonthValue else 0 end) as CurValue, --统计当月值

sum(case when a.Month=b.Month then b.MonthValue else 0 end) as TotValue --统计累计值

from (select Month=cast(1 as int) union select 2 union select 3 union select 4

union select 5 union select 6 union select 7 union select 8

union select 9 union select 10 union select 11 union select 12) a --生成月的基准值

join (select BFactoryName,LineName,Month,sum(Value)/12 as MonthValue

from T where FactoryName='F' and Year=2012 group by BFactoryName,LineName,Month) b on 1=1

group by b.BFactoryName,b.LineName,a.Month

) x

left outer join

(select BFactoryName,LineName,sum(Value)/12 as BaseValue--统计基准值

from T where FactoryName='F' and Year=2012-1 group by BFactoryName,LineName) y

on x.BFactoryName=y.BFactoryName and x.LineName=y.LineName

如何统计sqlserver多张表的数据总数

SqlServer中这样统计:

select name from sysobjects where xtype='U'

要知道总数的话就简单了：

select count(*) from sysobjects where xtype='U'

Oracle中这样查询：

Select * From user_tables;

SQLserver2005如何查询数据库中某一段时间内某个字段的累加和

select CONVERT(varchar(12) , 日期字段,112 ),sum(累加字段) from 表名 where 日期字段 between '2013-01-01' and '2013-01-31' group by CONVERT(varchar(12) , 日期字段,112 )

日期区间我用的1月1号到1月31号，你自己改一下吧
