python - How do you insert 3 lines' data into MySQL table (which has 10 lines) after its 5th line? -
why this: in fact create mysql table save data(open price, close price ,high price , on) of 3000 stocks; many days after created it, should update new data; should insert data after lines; yes create 1 table 1 stock, when read out them, time wasted.
