在订单表中状态为“采购中”的订单， 并且对应的订单明细表中排除该笔订单明细中已经到货的，只要有一项的预计到货日期和今天日期差3天以内， 将订单表中标记一个颜色，如果已经超过今天的日期并且未到货，那就标记另外一个颜色
BIN 大哥 看来还得做个辅助列是吧？ 把cmd.CommandText 中的内容做为一个辅助列估计就可以了吧 |

还是做一个辅助列吧 估计就可以了 |
| -- 作者：jspta -- 发布时间：2014/5/15 13:41:00 -- 加个辅助列肯定可以了，基本上也就没感觉 |
| -- 作者：jiskin -- 发布时间：2014/5/15 16:18:00 -- Select _Identify,OrderNumber,OrderDate,Supplier,InvoiceNumber,InvoiceDate,UserName,Status, (Select DISTINCT OrderNumber from Purchase_Orders b where (Select Status from Purchase_List where OrderNumber = b.OrderNumber) = \'采购中\' and b.Quantity - (select sum(Quantity) from IQC_Details where Identify = b._Identify) > 0 And DATEDIFF(day,GETDATE(),b.DeliveryDate) between 0 and 3) as 辅助 from Purchase_List a 这样做辅助列 辅助列里居然没数据，是不是哪里写错了啊 求帮忙看看

Select _Identify,OrderNumber,OrderDate,Supplier,InvoiceNumber,InvoiceDate,UserName,Status,
((Select top 1 OrderNumber from Purchase_Orders b where (Select Status from Purchase_List where OrderNumber = b.OrderNumber) = \'采购中\'
and b.Quantity - (select sum(Quantity) from IQC_Details where Identify = b._Identify) > 0
And DATEDIFF(day,GETDATE(),b.DeliveryDate) between 0 and 3) is null) as 辅助
from Purchase_List a

甜总， 辅助列到时候就为了判断空和非空 加了 is null 会报错，关键字 is 附近有语法错误，去掉is null 后辅助列还是没有数据
