使用实体框架从存储过程获取多个字符串输出

Question

以下存储过程显示三个字符串和一个表格行结果作为输出。 有什么办法可以使用实体框架在mvc视图输出面板上显示所有结果？

我可以在下面的代码中看到第一个字符串结果。但是无论如何要得到另外两个选择字符串输出和 表格结果。

private CustomerEntities db = new CustomerEntities(); 
     public ActionResult Index() 
     { 
      var results = db.usp_CustomerData("124544", 1500); 
      var abc = results.ToList(); 
      return View(); 
     } 

ALTER PROCEDURE [dbo].[usp_CustomerData] 
@CustomerID varchar(6), 
@MinsBack int 
AS 
BEGIN 

    DECLARE @Count int 
    SET @Count = (SELECT Count(*) 
        FROM Customer WITH (NOLOCK) 
        WHERE CustomerID = @CustomerID AND      
          DATEDIFF(mi, ReceivedAt, GETUTCDATE()) < @MinsBack) 
    IF (@Count = 1) 
     SELECT 'Ok: 1 message in Customer table' 
    ELSE 
     SELECT 'ERROR: Expected 1 message in Customer table, but found ' + CONVERT(varchar(3), @Count) + ' messages.' 


    SET @Count = (SELECT Count(*) 
        FROM CustomerDetails WITH (NOLOCK) 
        WHERE CustomerID = @CustomerID AND 
          DATEDIFF(mi, LastUpdatedAt, GETDATE()) < @MinsBack) 
    IF (@Count = 1) 
     SELECT 'Ok: 1 record in CustomerDetails table' 
    ELSE 
     SELECT 'ERROR: Expected 1 record in CustomerDetails table, but found ' + CONVERT(varchar(3), @Count) + ' records.' 


    SET @Count = (SELECT Count(*) 
        FROM CustomerProduct WITH (NOLOCK) 
        WHERE CustomerID = @CustomerID AND 
          DATEDIFF(mi, LastUpdatedAt, GETDATE()) < @MinsBack) 
    IF (@Count = 1) 
     SELECT 'Ok: 1 record in CustomerProduct table' 
    ELSE 
     SELECT 'ERROR: Expected 1 record in CustomerProduct table, but found ' + CONVERT(varchar(3), @Count) + ' records.' 

    SELECT *FROM Customer where customerID = @CustomerID 

END 

Answer 1

建议您可以在您的SQL脚本中创建一个用作临时存储的临时表。

CREATE TABLE #Results 
(
    Message VARCHAR(512) 
) 

而不是在每个IF直接SELECT或ELSE你应该插入串入临时表。 在最后你可以达到你的目标是让所有插入的字符串由返回他们：

SELECT * FROM #Results 

得到客户 - 就像你在做到底 - 你应该触发一个新的查询数据库。

根据您的情况，您应该考虑通过数据上下文查询数据库，而不是通过存储过程查询数据库。

你需要做的是在本link建议，但我总结如下

对于每个结果集，你需要做一个reader.NextResult（）;

var someReturnObject = new ResultObject(); 

using (var context = new LinqPadDbContext(@"Server=localhost\SQLEXPRESS;Database=StackOverflow;Trusted_Connection=True;")) 
{ 
    var cmd = context.Database.Connection.CreateCommand(); 
    cmd.CommandText = "[dbo].[GetSomeData]"; 

    try 
    {   
     context.Database.Connection.Open(); 

     var reader = cmd.ExecuteReader(); 

     var result1 = ((IObjectContextAdapter)context).ObjectContext.Translate<string>(reader); 

     someResultObject.Text1 = result1.First(); 

     //for each extra result, start here 
     reader.NextResult(); 

     var users = ((IObjectContextAdapter)context).ObjectContext.Translate<User>(reader); 

     someResultObject.Users = users.Select(x => x); 
     //stop here 
    } 
    finally 
    { 
     context.Database.Connection.Close(); 
    } 
}
