我有一个表想把里面的数据做成大纲样式的显示出来

babywywy 2008-01-15 09:43:03
我有一个这样的表():
MenuID OrderID MenuDeep MenuCode MenuName
1 1 1 A 实体
2 1 2 A01 企业
3 2 2 A02 自然人
4 2 1 B 交易
5 1 2 B01 交易1
6 1 3 B0101 交易11
7 1 4 B010101 交易111
8 2 2 B02 交易2
靠MenuDeep分层次靠MenuCode分归属,例如:交易1-〉交易11-〉交易111这样归属,本来这个表是用树控件来显示数据的,后来根据需要我做成以下样子:
实体 企业
实体 自然人
交易 交易1 交易11 交易111
交易 交易2
这样的一个结构显示出来,用sql 语句有法实现吗?
我这样写了一个语句,但是没成功:
select a.MenuName,b.MenuName,c.MenuName,d.MenuName
from
(
select MenuID,PartID,TaskID,OrderID,MenuDeep,MenuCode,MenuName,MenuPage,MenuType
from dbo.Syst_SearchMenu
where MenuDeep = 1
) a,
(
select MenuID,PartID,TaskID,OrderID,MenuDeep,MenuCode,MenuName,MenuPage,MenuType
from dbo.Syst_SearchMenu
where MenuDeep = 2
) b,
(
select MenuID,PartID,TaskID,OrderID,MenuDeep,MenuCode,MenuName,MenuPage,MenuType
from dbo.Syst_SearchMenu
where MenuDeep = 3
) c,
(
select MenuID,PartID,TaskID,OrderID,MenuDeep,MenuCode,MenuName,MenuPage,MenuType
from dbo.Syst_SearchMenu
where MenuDeep = 4
) d
where Left(b.MenuCode,1) = Left(a.MenuCode,1) and
(Left(c.MenuCode,1) = Left(a.MenuCode,1) and Left(c.MenuCode,3) = Left(b.MenuCode,3)) and
(Left(d.MenuCode,1) = Left(a.MenuCode,1) and Left(d.MenuCode,3) = Left(b.MenuCode,3) and
Left(d.MenuCode,5) = Left(c.MenuCode,5))

直接用sql 写不出来,可创建一函数,或用游标实现.

bom成本计算

表一:品号信息档
品号 品号属性 材料成本 人工成本 本阶人工
MB001 MB025 MB057 MB058 MB061
A M 2
B M 1
C P 2
D P 3
(MB025=M 时只有本阶人工是基础数据,其他的是计算过来的,MB025=P时只有MB057有基础数据)


表二(BOM)
主件品号 元件品号 用量
A B 2(A由2个B组成)

B C 1 (B由1个C和3个D组成)
B D 3

计算原理:
1、计算MB025=M 的人工成本,人工成本=本阶人工+下阶人工成本
2、计算材料成本,材料成本=本阶用到材料+下阶材料之和(如本例

结果:
MB001 MB025 MB057 MB058 MB061
A M 22 4 2
B M 11 1 1
C P 2 0 0
D P 3 0 0

11=(3D+1C)=11
22=11*2
4=2B+2










go
