试试

//存储过程调用.它已经在示例数据库中.
cmd.CommandText ="SELECT [ClearanceNumber]，[CodeFlightId]，DateLastChange，DateValidFrom，DateValidTo，[ReservationNo]，[AircraftType]，[CityCode]，[days_t]为[Days] FROM [Flight]，其中[ClearanceNumber] ='' "+ Request.QueryString [" clr] +"'';

adapter = new SqlDataAdapter(cmd);
adapter.Fill(ds，"Users");
}
catch(ex ex例外)
{
抛出新的Exception(ex.Message);
}
终于
{
cmd.Dispose();
如果(Con.State！= ConnectionState.Closed)
Con.Close();
}
返回ds.Tables [0];
}
