您好我正在使用三个表来显示客户订单信息
1. Order table(OrderId, ItemName, Description, etc...)
2. Order_Gas_Quantity(Order_gas_quantyID, OrderID, Quantity)
3. Customer_Supplying_Days(SupplyingID, CustID, SupplyingDays)
在保存客户数据的同时,我将供应日期保存到customer_Suppling_Days
,在此表中我使用CustID
。
表1和表1也是2具有相同的ID OrderID
。
我想显示今天订购的商品以及提供日期。例如,在保存客户数据的同时,如果客户选择在周一,周三,周五需要,则可以选择日期。因此,应用程序应该为今天的订单生成报告,并且项目应该在周五提供。
customer_Suppling_Days
`SupplyDayID int Unchecked
CustID int Checked
SupplyDays nvarchar(50) Checked
Orders
OrderID int Unchecked
Date varchar(50) Checked
CName varchar(50) Checked
CustId int Checked
CLocation varchar(50) Checked
Gas varchar(50) Checked
Quantity varchar(50) Checked
VehicleNo varchar(50) Checked

Order_Gas_qty
OrderGasQty int Unchecked
CustId int Checked
GasName varchar(50) Checked
Quantity varchar(50) Checked
OrderDate varchar(50) Checked

答案 0 :(得分:0)
您已将日期保存为varchar()
格式强烈不推荐。仅以Date
格式存储日期。如果您无法更改表结构,那么简单的内连接应该起作用:
select O.OrderID,
O.Date,
O.CName,
O.Gas,
O.Quantity,
O.VehicleNo,
O.VehicleLocation,
O.[Source],
OGQ.CylinderNo
from Orders O
inner join Order_Gas_qty OGQ on OGQ.OrderId = O.OrderId
inner join Customer_Supplying_Days CSD on O.CustId = CSD.CustId
where O.Date = convert( varchar(20),getdate(),101)
-- please change the format here as per your requirement
and SupplyDayID = Day(getdate())
-- this condition also depends on data in your table
