在兩個不同的表中的webmatrix動態sql查詢

Question

我拉從前一頁的訂單ID從表中選擇特定的順序，並且工作正常。我還需要從該表中獲取CustomerID並查詢客戶表以返回具有該ID的條目。

@{ 
var id=Request["id"]; 
var SQLSELECT3 = "SELECT * FROM Ordr WHERE ID=@0"; 
var db = Database.Open("OMD"); 
var ordr = db.QuerySingle(SQLSELECT3,id); 
var oCustomerID=ordr.CustomerID; 
var oStatus=ordr.Status; 
var oID=ordr.ID; 
var oDate=ordr.Date; 
var oService=ordr.Service; 
var oNotes=ordr.Notes; 

var SQLSELECT = "SELECT * FROM Customer WHERE ID = @oCustomerID"; 
var customer = db.QuerySingle(SQLSELECT,id); 
var cLastName=customer.LastName; 
var cFirstName=customer.FirstName; 
var cAddress=customer.Address; 
var cCity=customer.City; 
var cState=customer.State; 
var cZip=customer.Zip; 
var cPhone1=customer.Phone1; 
var cPhone2=customer.Phone2; 
var cEmail=customer.Email; 
}

查詢更改爲

var SQLSELECT = "SELECT * FROM Customer WHERE ID = @0"; 
var customer = db.QuerySingle(SQLSELECT, (int)ordr.CustomerID); 

沒有與您的問題做的，但我不明白你爲什麼從查詢全部轉讓給你的值到另一組變量。在我看來，這是大量不必要的打字。
