MYSQL發送數據大小計算公式 Field definition sequence of packets + Data packets = (21 + length_of_data_filed(db_name) + length_of_data_filed(table_name) + 1 + length_of_data_filed(column_name) + 1) * field_number + 68 + 4 + k + field_number + 63 = (24 + length_of_data_filed(db_name) + length_of_data_filed(table_name) + length_of_data_filed(column_name)) * field_number + k + 135
