在两个不同的表中的webmatrix动态sql查询

Question

我拉从前一页的订单ID从表中选择特定的顺序，并且工作正常。我还需要从该表中获取CustomerID并查询客户表以返回具有该ID的条目。

@{ 
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; 
}

查询更改为

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

没有与您的问题做的，但我不明白你为什么从查询全部转让给你的值到另一组变量。在我看来，这是大量不必要的打字。
