Hi:

I want to generate a report b/w some time...I am using stored procedure for that...But i m not getting the desired result.Here is my code

SqlConnection sqlConnection = new SqlConnection(ConfigurationSettings.AppSettings["ConnectionString"]);
                  SqlCommand sqlCommand = new SqlCommand("gal_report_personnel", sqlConnection);
                  sqlCommand.CommandType = CommandType.StoredProcedure;
                  SqlDataAdapter sqlAdapter = new SqlDataAdapter();
                  sqlAdapter.SelectCommand = sqlCommand;
                  DataSet ds = new DataSet();

                  sqlCommand.Parameters.Add("@EffectiveDate1",SqlDbType.SmallDateTime,4);
