Asp.net 将SQL转换为LINQ

我有以下SQL。我需要把它转换成LINQ

ALTER VIEW [dbo].[vwRptBorrowerAccount]  
AS  
SELECT dbo.tblAccount.[Creditor Registry ID], dbo.tblAccount.[Account No], dbo.tblAccount.[Date Opened], dbo.tblAccount.[Account Status ID],   
               dbo.tblAccount.[Date First Reported], dbo.tblAccount.[Credit Limit], dbo.tblAccount.Balance, dbo.tblAccount.[Minimum Installment], dbo.tblAccount.[Account Type],   
               dbo.tblAccount.Term, dbo.tblAccount.Purpose, dbo.tblAccount.[Account Owner Notes], dbo.tblAccount.[Creditor Notes], dbo.tblAccount.Collateral,   
               dbo.tblAccount.[Collateral Value], dbo.tblAccount.[Legal Status ID], dbo.tblAccount.[Legal Status Date], dbo.tblAccount.LastUpdatedBy,   
               dbo.tblAccount.LastUpdated, dbo.tblAccount.[Unique ID], dbo.tblAccount.[Account Status Date], dbo.tblAccount.Payment, dbo.tblAccount.[Payment Date],   
               dbo.tblAccount.[Balance Date], dbo.tblAccount.[Term Frequency], dbo.tblAccount.[State Change Date],   
               dbo.fn_GetAccountTypeDescription(dbo.tblAccount.[Account Type]) AS [Account Type Description], dbo.tblBusiness.[Business Name] AS CreditorName,   
               dbo.tblBusiness.Address AS CreditorAddress, dbo.tblBusiness.City AS CreditorCity, dbo.tblBusiness.State AS CreditorState,   
               dbo.tblLegalStatus.[Legal Status Description] AS [Legal Status], dbo.tblAccountStatus.[Account Status Description] AS [Account Status],   
               dbo.tblAccountOwner.[Account Owner Registry ID]  
FROM  dbo.tblAccount INNER JOIN  
               dbo.tblAccountOwner ON dbo.tblAccount.[Creditor Registry ID] = dbo.tblAccountOwner.[Creditor Registry ID] AND   
               dbo.tblAccount.[Account No] = dbo.tblAccountOwner.[Account No] INNER JOIN  
               dbo.tblBusiness ON dbo.tblAccount.[Creditor Registry ID] = dbo.tblBusiness.[Registry ID] INNER JOIN  
               dbo.tblAccountStatus ON dbo.tblAccount.[Account Status ID] = dbo.tblAccountStatus.[Account Status ID] INNER JOIN  
               dbo.tblLegalStatus ON dbo.tblAccount.[Legal Status ID] = dbo.tblLegalStatus.[Legal Status ID]  
WHERE (dbo.tblAccount.[Account Type] NOT IN ('CA00', 'CA01', 'CA03', 'CA04', 'CA02', 'PA00', 'PA01', 'PA02', 'PA03', 'PA04')) 

[已编辑] 功能详情如下：

CREATE FUNCTION [fn_GetAccountTypeDescription]  
(  
 -- Add the parameters for the function here  
 @accountType varchar(max)  
)  
RETURNS varchar(max)  
with schemabinding  
AS  
BEGIN  
 -- Declare the return variable here  
 DECLARE @Result varchar(max)  

 -- Add the T-SQL statements to compute the return value here  
 IF EXISTS(SELECT Abbreviation FROM dbo.tblAccountType WHERE [Account Type Code] = @accountType)  
 BEGIN  
  SELECT @Result = Abbreviation FROM dbo.tblAccountType WHERE [Account Type Code] = @accountType  
 END  
 ELSE  
 BEGIN  
  SELECT @Result = @accountType  
 END  

 -- Return the result of the function  
 RETURN @Result  

END

您能建议如何将其转换为LINQ吗？我不想使用联接。

我认为没有联接，无论是否使用LINQ，您都无法做到这一点

此外，这似乎是徒劳的练习。您希望从投资中获得什么好处

---

此外，您还没有指定要使用的LINQ提供程序，因此您的问题完全无法回答。每个提供程序在语法上都有显著差异。

好的，请确保将tblAccountType添加到模型中，并且它与tblAccount有关联，然后执行如下操作

我的测试能力甚至不如您，但我建议您拥有一个具有相同模式的测试数据库，并用一些虚拟数据填充它

String[] excludedCodes = new String[]
    {
        "CA00",
        "CA01",
        "CA03",
        "CA04",
        "CA02",
        "PA00",
        "PA01",
        "PA02",
        "PA03",
        "PA04"
    };

var data = context.tblAccount.Where(a => !excludedCodes.Contains(a.AccountType))
    .Select(a => new{
            a.Creditor_Registry_ID,
            a.Account_No,
            a.Date_Opened,
            ...
            Account_Type_Description = a.tblAccountType.Where
                (t => t.Account_Type_Code = a.Account_Type).SingleOrDefault() 
                   ??  a.Account_Type),
            Creditor_Name = a.tblBusiness.Business_Name,
            CreditorAddress = a.tblBusiness.Address,
            ...
            Legal_Status = a.tblLegalStatus.Legal_Status_Description,
            ... etc.
        });

我想使用关联。实体是通过相关属性链接的。最尴尬的是fn_GetAccountTypeDescription@Jodrell：我更新了问题以显示fn_GetAccountTypeDescription您可以使用设计用于完成这类工作的应用程序，如linqpad或linqer。。。为什么要将其转换为LINQ？您试图从此查询创建哪些对象？如果您只是试图检索查询结果，那么使用ORM是没有意义的——实际上这样做是个坏主意。林克：顺便问一下，你想干什么？LINQ到SQL？实体？尼伯酸盐？每个ORM都有自己的方法来指定应同时加载某些实体，而不是单独加载每个实体。我在asp.net中设计了一个应用程序，我正在使用LINQ和entities Framework 4.1将其转换为MVC3，这就是其中的一部分。我没有表格中的数据，因此我无法验证我是否正确地进行了操作。
