SQL-Server-2005

I am working with C# and MSSQL 2005 database.

I have this code, but my DataTable is not getting loaded with any data.

C#

var conn = new SqlConnection(ConnectionString);
var cmd = new SqlCommand
              {
                    Connection = conn,
                    CommandText = "LoadAppointment",
                    CommandType = CommandType.StoredProcedure
              };
cmd.Parameters.Add(new SqlParameter("Parametr Name", "Parameter value"));
cmd.Connection.Open();
var dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
var dt = new DataTable();
dt.Load(dr);

Any help regarding this will be appreciated a lot. Thanks in advance!!

Of course not.. Because the code is commented

I just wanted to know why it does not works when it is uncommented too.

var command = new SqlCommand("LoadAppointment", _conn) { CommandType = CommandType.StoredProcedure };
_conn.Open();
var dr = command.ExecuteReader(CommandBehavior.CloseConnection);
var dt = new DataTable();
dt.Load(dr);

do not use var //dr = cmd.ExecuteReader(CommandBehavior.CloseConnection); instead use
SqlDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
DataTable dt = new DataTable();
//dt.Load(dr);

Tried it as per ur advice. But it doesn't made any difference.

Even tried of Building the solution again.

Presumably your parameter name is correctly formatted, your parameter value is a variable and is populated and passed in correctly and presumably you have debugged the code to check the procedure is called correctly and you have tested the procedure in SSMS with the parameter passed in.

I dont have any Parameters for the Stored Procedure i am using.

Mycroft Holmes 4-Mar-13 4:10am

WAT then why are you creating a Parameter and adding it to the command. This MUST generate a sql error.

ArunAmalraj 4-Mar-13 4:15am

I really dont get what you mean.

This is my code

_conn = new SqlConnection(ConnectionString);
_conn.Open();
var command = new SqlCommand("LoadAppointment", _conn) { CommandType = commandType.StoredProcedure };

SqlDataReader dr = command.ExecuteReader(CommandBehavior.CloseConnection);
DataTable dt = new DataTable();
dt.Load(dr);

And, this is my stored Procedure

USE [Scheduler]
GO
/****** Object: StoredProcedure [dbo].[LoadAppointment] Script Date: 03/04/2013 14:44:28 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[LoadAppointment]

AS

SELECT * FROM [Scheduler].[dbo].[tblAppointments]

Note: My Stored Procedure Name is passed as a parameter associated with the Connection String.
