CREATE TABLE stu(id INT,NAME VARCHAR(32),age INT,TIME TIMESTAMP);
INSERT INTO stu(id,NAME,age,TIME)VALUES(1,"lqx",18,NULL);
INSERT INTO stu(id,NAME,age,TIME)VALUES(2,"ytt",120,NULL);
INSERT INTO stu(id,NAME,age,TIME)VALUES(3,"yt",108,"1998-08-10");
DELETE FROM stu WHERE id=2;

limit 是mysql的“方言”，不同数据库分页操作可能不同~~~
