分组求和统计，with rollup 、with cube、grouping 统计函数用法

SQL code

CREATE TABLE [kc1] (
    [djrq] [smalldatetime] NULL ,
    [djlx] [nvarchar] (20),
    [kfmc] [nvarchar] (50),
    [hpmc] [nvarchar] (50),
    [zl] [float] NULL 
)
GO

/* 求2个时间段：2010-03-20至2010-03-26
要得到这样的报表： 
库房名称    起始时间       入库      出库     结余数量
kfmc       djrq           zl        zl        zl
半成品     2010-03-20     39        -7        98      
销售仓库   2010-03-20     11        0         11
预混料     2010-03-20     2         0         2
原 料     2010-03-20      5         -1        7

备注：根据输入的2个时间参数，按照库房名称分组求和
入库方法：

SQL code

SELECT kfmc,
SUM(zl)AS 入库
FROM kc1 where djlx like '%入库%' group by kfmc

出库方法：

SQL code

SELECT kfmc,
SUM(zl)AS 出库
FROM kc1 where djlx like '%出库%' group by kfmc

SQL code

结余数量:
select kfmc,sum(zl) from kc1 group by kfmc
