Question

用SQL语句随便写一条数据库增删改查语句？

Answer 1

表名: person
字段: id, name, age
1 张三 20
2 李四 22
3 王五 23

查询: select id,name,age from person;
删除: delete from person where id=1 (删除ID=1的那条数据,)
delete from person (删除person表中的所有数据);
修改: update person set name="刘德华" where id=2; (就会李四的名字改成刘德华);
增加: insert into person values(4,'赵六',24);
