問題描述

問題解答

1、獲取當前最大id,max(id)+1

INSERT INTO myTable (name,sort) SELECT ’Ali’ as name,max(id)+1 as sort FROM myTable;

2、觸發(fā)器CREATE TRIGGER t_afterinsert_on_myTable AFTER INSERT ON myTableFOR EACH ROWBEGIN

update myTable set sort=id where id=new.id;

END;然后插入的時候只要插入name值，INSERT INTO myTable (name) VALUES (’Ali’);

當然是第一種比較簡單。。。
