第六章 插入，更新和删除数据

第一节：插入数据

1，给表的所有字段插入数据

格式：INSERT INTO 表名 VALUES(值 1，值 2，值 3，...，值 n)；

INSERT INTO t_book VALUES(NULL,'我爱我家',20,'张三',1);

2，给表的指定字段插入数据

格式：INSERT INTO 表名(属性 1，属性 2，...，属性 n) VALUES(值 1，值 2，值 3，...，值 n)；

INSERT INTO t_book(id,bookName,price,author,bookTypeId) VALUES(NULL,'我爱我家',20,'张三',1);

INSERT INTO t_book(bookName,author) VALUES('我爱我家','张三');

3，同时插入多条记录

INSERT INTO 表名 [(属性列表)]
VALUES(取值列表 1)，(取值列表 2)
...，
(取值列表 n)；

INSERT INTO t_book(id,bookName,price,author,bookTypeId) VALUES (NULL,'我爱我家2',20,'张三',1),(NULL,'我爱我家3',20,'张三',1);

第二节：更新数据


UPDATE 表名
SET 属性名 1=取值 1，属性名 2=取值 2，
...，
属性名 n=取值 n
WHERE 条件表达式；

UPDATE t_book SET bookName='Java编程思想',price=120 WHERE id=1;

UPDATE t_book SET bookName='我' WHERE bookName LIKE '%我爱我家%';

第三节：删除数据

DELETE FROM 表名 [WHERE 条件表达式]

DELETE FROM t_book WHERE id=5;

DELETE FROM t_book WHERE bookName='我';

维护大学表的时候用的脚本：
