如何在sql中向存储过程发送三个参数?
这是我的错误:过程或函数GetIslemIdleri指定了太多参数。
这是我的存储过程:
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
这是我的代码:
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;
感谢您的帮助。

存储过程称为GetIslemDetayIdleri
,但代码使用名为GetIslemIdleri
的存储过程。也许后者的参数比前者少,你打算在代码中调用前者?
答案 1 :(得分:3)
GetIslemDetayIdleri!= GetIslemIdleri
答案 2 :(得分:2)
您的存储过程:GetIslemDetayIdleri
与您的调用具有不同的名称:
cmd = new SqlCommand("GetIslemIdleri", sqlConn);
答案 3 :(得分:0)
在我的情况下,此代码有效。我希望这对您的情况有效
过程参数名称、类型和长度必须相同
就这样
cmd.Parameters.Add(new SqlParameter("@islemId", SqlDbType.Int)).Value = islemId;
cmd.Parameters.Add(new SqlParameter("@dovizTanim", SqlDbType.NVarChar ,10)).Value = dovizTanim;
cmd.Parameters.Add(new SqlParameter("@yapilanIslemTuru", SqlDbType.NVarChar,20)).Value = yapilanIslemTipi;
