疑难问题

HappyQQ 2010-01-10 03:24:18
表TblCustomerTest有以下字段.
CustomerNo,CustomerName
'A001','A0001对应的名称'
'A002','A0002对应的名称'
'A003','A0003对应的名称'
'A004','A0004对应的名称'
'A005','A0005对应的名称'
'A006','A0006对应的名称'

表TblNode有以下字段(注MainBranch只取固定值'0001','0002','0003','0004',BankNodeNo 只取TblNode表字段NodeNo值字段)
NodeNo,NodeName,CustomerNo,MainBranch,BankNodeNo
内容如下,
'N0001','N0001Name','A001','0001','N0002'
'N0002','N0002Name','A001','0001','N0003'
'N0003','N0003Name','A003','0002,'N0003'
'N0004','N0004Name','A003','0002,'N0003'
'N0005','N0005Name','A004','0003,'N0004'
'N0006','N0006Name','A004','0004,'N0003'
'N0007','N0007Name','A005','0001,'N0003'
'N0008','N0008Name','A006','0003,'N0005'
'N0009','N0009Name','A006','0004,'N0005'

已知一个结果表TblReportB表:
CustomerNo,MainBranch,Cost,OtherNum
'A001','0001',1000,0
'A002','0002',1200,0
'A003','0002',1300,0

我需要核算TblReportB表中的OtherNum值.需要以下处理.

更新TblReportB的OtherNum字段需要符合以下要求.
统计TblNode的CustomerNo属于TblCustomerTest,且MainBranch属于固定值'0001','0002','0003','0004',
并且BankNodeNo属于TblNodes的值.

我的处理方式如下，但不是我想要的结果。
请大家帮我处理一下游标中的SQL语句。


DECLARE crsBranch CURSOR FORWARD_ONLY STATIC FOR
--四个固定值
Select BranchNo = '0001'
Union All
Select BranchNo = '0002'
Union All
Select BranchNo = '0003'
Union All
Select BranchNo = '0004'

OPEN crsBranch
FETCH NEXT FROM crsBranch INTO @MainBranch
WHILE @@FETCH_STATUS = 0
BEGIN

Update [TblReportB]
Set OtherNum = b.SNodeNum
From [TblReportB] as a
Join (
Select Cust.CustomerNo,SNodeNum = Count(*) From
TblNode Node
Left Join
TblCustomerTest Cust
On Cust.CustomerNo = Node.CustomerNo And Node.MainBranch=@MainBranch
And Node.BankNodeNo in
(
Select Node.NodeNo From
TblNode Node
Left Join
TblCustomerTest Cust
On Cust.CustomerNo = Node.CustomerNo And Node.MainBranch=@MainBranch
)
Group by Cust.CustomerNo
Having Cust.CustomerNo is not null
) as b
On a.CustomerNo =b.CustomerNo And MainBranch =@MainBranch
FETCH NEXT FROM crsBranch INTO @MainBranch
END

DEALLOCATE crsBranch



我需要的结果是：
预期结果表TblReportB表的值:
CustomerNo,MainBranch,Cost,OtherNum
'A001','0001',1000,2
'A002','0002',1200,0
'A003','0002',1300,2

哪位朋友帮帮忙。

原来是我第一个存储过程的错,那位帮助我的朋友,我们的结果都没错.

所以考虑问题以后一定不要认为自己的后来的程序有问题.

方便留下其他联系方式吗?

我这个问题苦恼了我一天了,其他我都算出来了,就差一个字段没核算出来了.

兄弟你的核算结果与我的SQL结果好像一样.

兄弟,你没有把BankNodeNo 考虑进去.

在核算时,需要将核算的条件都要考虑进去.

标红色的记录是属于我要求的记录.
所以最后

TblReportB表的值将是:
CustomerNo,MainBranch,Cost,OtherNum
'A001','0001',1000,2
'A002','0002',1200,0
'A003','0002',1300,2

未核算之前
TblReportB表已存在以下记录:
CustomerNo,MainBranch,Cost,OtherNum
'A001','0001',1000,0
'A002','0002',1200,0
'A003','0002',1300,0

核算之后的值:
TblReportB表:
CustomerNo,MainBranch,Cost,OtherNum
'A001','0001',1000,2
'A002','0002',1200,0
'A003','0002',1300,2

核算的条件是:
统计TblNode表中CustomerNo属于TblCustomerTest,且MainBranch属于固定值'0001','0002','0003','0004',
并且TblNode表中BankNodeNo字段值属于TblNode的NodeNo字段.

表TblNode
NodeNo,NodeName,CustomerNo,MainBranch,BankNodeNo
'N0001','N0001Name','A001','0001','N0002'
'N0002','N0002Name','A001','0001','N0003'

已知一个结果表TblReportB表:
CustomerNo,MainBranch,Cost,OtherNum
'A001','0001',1000,0
'A002','0002',1200,0
'A003','0002',1300,0


我需要核算TblReportB表中的OtherNum值.需要以下处理.
条件是:
统计TblNode的CustomerNo属于TblCustomerTest,且MainBranch属于固定值'0001','0002','0003','0004',
并且BankNodeNo属于TblNodes的值.
正确的结果是:
CustomerNo,MainBranch,Cost,OtherNum
'A001','0001',1000,2
'A002','0002',1200,0
'A003','0002',1300,2

其他,请参考我的那段SQL语句.
