MysqlConnection con = new mysqlConnection(ConfigurationManager.ConnectionStrings["dbConnectionString"].ToString());
mySqlCommand read_command = new mySqlCommand("SELECT SUM(Length) FROM tbl_test ID =@ID and date=@date", con);
read_command.Parameters.Add("@Date", SqlDbType.Date).Value = yesterday ;
mySqlDataReader read_rd;
string SUM ;
try
{
con.Open();
read_rd = read_command.ExecuteReader();
if (read_pass_rd.HasRows)
{
while (read_rd.Read())
{
SUM = read_rd.GetString(0);
}
}
read_rd.Close();
