passing parameters to a stored procedure in C#
How can i send three parameters a to stored procedure in sql?
Here is my error: Procedure or function GetIslemIdleri has too many arguments specified.
This is my stored procedure:
CREATE PROCEDURE GetIslemDetayIdleri
@islemId int,
@dovizTanim nvarchar(10),
@yapilanIslemTuru nvarchar(20)
AS
BEGIN
SET NOCOUNT ON;
SELECT ([t0].[TOPLAMTUTAR]) 开发者_JAVA技巧+ ([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
Here is my code:
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;
Thanks for your helps.
The stored procedure is called GetIslemDetayIdleri
but the code is using a stored procedure called GetIslemIdleri
. Maybe the latter has fewer parameters than the former and you meant to call the former in the code?
Your stored procedure: GetIslemDetayIdleri
have different name then your invocation:
cmd = new SqlCommand("GetIslemIdleri", sqlConn);
GetIslemDetayIdleri != GetIslemIdleri
in my case this code is worked .i hope this will work for your case
Procedure parameter names , type and lenght must be same
like that
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;
