傳遞參數到存儲過程在C＃

Question

我如何發送三個參數到存儲過程在sql中？

這是我的錯誤：過程或函數GetIslemIdleri指定的參數太多。

這是我的存儲過程：

CREATE PROCEDURE GetIslemDetayIdleri 

@islemId int, 
@dovizTanim nvarchar(10), 
@yapilanIslemTuru nvarchar(20) 
AS 
BEGIN 
    SET NOCOUNT ON; 

SELECT ([t0].[TOPLAMTUTAR]) + ([t0].[KDVTUTAR]) AS [value] 
FROM [dbo].[TBLP1ISLEMDETAY] AS [t0] 
INNER JOIN [dbo].[TBLP1ISLEM] AS [t1] ON [t1].[ID] = [t0].[ISLEM_ID] 
WHERE ([t0].[ISLEM_ID] = @islemId) AND 
     ([t0].[FIYATBIRIM] = @dovizTanim) AND 
     ([t1].[YAPILANISLEM] = @yapilanIslemTuru) AND 
     ([t0].[KDVDAHILMI] = 0) 
END 

這裏是我的代碼：

 decimal kurToplamQuery = 0; 
     string connString = System.Configuration.ConfigurationManager.ConnectionStrings["LocalSqlServer1"].ConnectionString; 

     SqlConnection sqlConn = new SqlConnection(connString); 
     sqlConn.Open(); 

     SqlCommand cmd; 

     cmd = new SqlCommand("GetIslemIdleri", sqlConn); 
     cmd.CommandType = CommandType.StoredProcedure; 
     cmd.Parameters.Add(new SqlParameter("@islemId", SqlDbType.Int)).Value = islemId; 
     cmd.Parameters.Add(new SqlParameter("@dovizTanim", SqlDbType.NVarChar)).Value = dovizTanim; 
     cmd.Parameters.Add(new SqlParameter("@yapilanIslemTuru", SqlDbType.NVarChar)).Value = yapilanIslemTipi; 

     using (var reader = cmd.ExecuteReader())*//error occurs here* 
     { 
      while (reader.Read()) 
      { 
       kurToplamQuery = reader.GetDecimal(0);      
      } 
     } 
     sqlConn.Close(); 
     return kurToplamQuery; 

感謝您的幫助。

Answer 1

該存儲過程被稱爲GetIslemDetayIdleri，但代碼使用名爲GetIslemIdleri的存儲過程。也許後者的參數比前者少，你打算在代碼中調用前者？

Answer 2

您的存儲過程：GetIslemDetayIdleri有不同的名稱，然後你調用：

cmd = new SqlCommand("GetIslemIdleri", sqlConn); 

Answer 3

GetIslemDetayIdleri = GetIslemIdleri
