【问题描述】：
在 SQL Server 2008 R2 上，我正在尝试创建一个存储过程，该过程将根据用户输入的范围为用户提供商品小计。我将不胜感激。
但是，我遇到了一个问题，查询显示所有正在计算的商品，因此用户以最终超出其输入范围的值结束。我将在底部包含一些示例数据以及我尝试过的数据。
这是一个示例（为了清楚起见，我在此示例中删除了一些列）：
如您所知，对于 2000 到 10000 之间的范围，商品 998-32 的小计将超过 10000，但仍会显示，因为每个 PO NO 单独小于 10000。
这是一些示例数据：
DROP TABLE ##mytable;
CREATE TABLE ##mytable(
Commodity VARCHAR(15) NOT NULL
,PO_NO INTEGER NOT NULL
,LINE_NO INTEGER NOT NULL
,PO_Line_Description VARCHAR(82)
,Commodity_Description VARCHAR(60) NOT NULL
,Fiscal_Year INTEGER NOT NULL
,Vendor_ID INTEGER NOT NULL
,Vendor_Name VARCHAR(20) NOT NULL
,QUANTITY INTEGER NOT NULL
,UNIT_COST NUMERIC(7,2) NOT NULL
,Line_Amount NUMERIC(7,2) NOT NULL
);
INSERT INTO ##mytable(Commodity,PO_NO,LINE_NO,PO_Line_Description,Commodity_Description,Fiscal_Year,Vendor_ID,Vendor_Name,QUANTITY,UNIT_COST,Line_Amount) VALUES ('998-18',1448923,1,'Face Scholastic book order attached.','Sale of Surplus and Obsolete Books',2015,47650,'SCHOLASTIC INC',1,9999.8,9999.8);
INSERT INTO ##mytable(Commodity,PO_NO,LINE_NO,PO_Line_Description,Commodity_Description,Fiscal_Year,Vendor_ID,Vendor_Name,QUANTITY,UNIT_COST,Line_Amount) VALUES ('998-32',1416311,2,'First 12 months maintenance agreement to be billed quarterly at .0039 per b/w copy','Sale of Surplus and Obsolete Copy Machines',2015,341479,'RICOH USA, INC',1,5148,5148);
INSERT INTO ##mytable(Commodity,PO_NO,LINE_NO,PO_Line_Description,Commodity_Description,Fiscal_Year,Vendor_ID,Vendor_Name,QUANTITY,UNIT_COST,Line_Amount) VALUES ('998-32',1424377,1,NULL,'Sale of Surplus and Obsolete Copy Machines',2015,300590,'KONICA MINOLTA/ CIT',1,2894.58,2894.58);
INSERT INTO ##mytable(Commodity,PO_NO,LINE_NO,PO_Line_Description,Commodity_Description,Fiscal_Year,Vendor_ID,Vendor_Name,QUANTITY,UNIT_COST,Line_Amount) VALUES ('998-32',1404031,1,'1st (12) months of (36) month Lease payment for (1) MPC4503 copier.','Sale of Surplus and Obsolete Copy Machines',2015,341479,'RICOH USA, INC',1,2050.68,2050.68);
INSERT INTO ##mytable(Commodity,PO_NO,LINE_NO,PO_Line_Description,Commodity_Description,Fiscal_Year,Vendor_ID,Vendor_Name,QUANTITY,UNIT_COST,Line_Amount) VALUES ('998-75',1401552,1,'Blanket order for 50 teachers - each teacher not to exceed $100.00.','Sale of Surplus and Obsolete Paper and Paper Products',2015,27536,'KNOWLEDGE TREE',1,5000,5000);
INSERT INTO ##mytable(Commodity,PO_NO,LINE_NO,PO_Line_Description,Commodity_Description,Fiscal_Year,Vendor_ID,Vendor_Name,QUANTITY,UNIT_COST,Line_Amount) VALUES ('998-78',1521390,1,'PL02286>PRESSURE PLUMBER INSTANT DRAIN OPENER 24 SHOT CARTRIDGE','Sale of Surplus and Obsolete Plumbing Equipment and Supplies',2015,402985,'TECH MECH SUPPLY LLC',480,8,3840);
我尝试使用 SUM() OVER (PARTITION BY [ ] ORDER BY [ ] ROWS UNBOUNDED PRECEDING)，但显然带有 ROW 的 OVER 子句是在 SQL Server 2012 中引入的，不适用于 2008 R2。
我也尝试过使用 GROUP BY ROLLUP，但我收到一条消息，上面写着“CUBE() 和 ROLLUP() 分组结构在当前兼容模式下是不允许的。它们只在 100 或更高模式下允许。”当我问我们的 DBA 时，他说我们不能从 90 模式转移到 100 模式，因为很多事情都会中断。
所以现在我被下面的查询困住了，它有前面提到的问题，给我我想要的数据的问题，以及最终将超出我指定范围的数据的小计。
附：我还注意到，如果商品的 PO NO 在我选择的范围内，但也有 PO NO 的成本超出此范围，则此查询将为我提供所选范围内的 PO NO，这是非常具有误导性的，因为它仍然是一种商品如果全部计算在内，则超出所选范围。它们根本不应该与真正在我选择范围内的商品一起列入结果。
