using a stored procedure for login in c#
- by Jin Yim
Hi all,
If I run a store procedure with two parameter values (admin, admin)
(parameters : admin, admin)
I get the following message :
Session_UID User_Group_Name Sys_User_Name
NULLAdministratorsNTMSAdmin
No rows affected.
(1 row(s) returned)
@RETURN_VALUE = 0
Finished running [dbo].[p_SYS_Login].
--
To get the same message in c# I used the code following :
string strConnection = Settings.Default.ConnectionString;
using (SqlConnection conn = new SqlConnection(strConnection))
{
using (SqlCommand cmd = new SqlCommand())
{
SqlDataReader rdr = null;
cmd.Connection = conn;
cmd.CommandText = "p_SYS_Login";
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter paramReturnValue = new SqlParameter();
paramReturnValue.ParameterName = "@RETURN_VALUE";
paramReturnValue.SqlDbType = SqlDbType.Int;
paramReturnValue.SourceColumn = null;
paramReturnValue.Direction = ParameterDirection.ReturnValue;
cmd.Parameters.Add(paramReturnValue);
cmd.Parameters.Add(paramGroupName);
cmd.Parameters.Add(paramUserName);
cmd.Parameters.AddWithValue("@Sys_Login", "admin");
cmd.Parameters.AddWithValue("@Sys_Password", "admin");
try
{
conn.Open();
rdr = cmd.ExecuteReader();
string test = (string)cmd.Parameters["@RETURN_VALUE"].Value;
while (rdr.Read())
{
Console.WriteLine("test : " + rdr[0]);
}
}
catch (Exception ex)
{
string message = ex.Message;
string caption = "MAVIS Exception";
MessageBoxButtons buttons = MessageBoxButtons.OK;
MessageBox.Show(
message,
caption,
buttons,
MessageBoxIcon.Warning,
MessageBoxDefaultButton.Button1);
}
finally
{
cmd.Dispose();
conn.Close();
}
}
}
but I get nothing in SqlDataReader rdr ;
is there something I am missing ?
Thanks
