insert into 1.指定列插入 语法insert into table_name(列名1,列名2,....,列名n) values (值1,值2,...,值n),(值1,值2,...,值n),....,(值1,值2,...,值n); 2.全部列插入 语法insert into tablename values (值1,值2,...,值n),(值1,值2,...,值n),....,(值1,值2,...,值n);
示例
-- 指定列名插入
insert into test_user(user_id,user_name,nick_name)
values
(1,mytest1,测试账号1),
(2,mytest2,测试账号2);
-- 不指定列直接插入所以列的值
insert into test_user
values
(3,1,mytest3,测试账号3,1,3030qq.com,18512345678,0,12345678,0,测试),
(4,1,mytest4,测试账号4,1,3031qq.com,18512345679,0,12345678,0,测试1);注意插入数据时需要注意插入的值和对应列的字段类型需要保持一致 2.删除数据
delete 语法
delete from table_name;或
delete from table_name
where 条件;示例
-- 删除指定条件的数据
delete from test_user
where user_name mytest1;
-- 删除指定表中所有数据
delete from test_user;注意不带where时会把表中所有的数据都删掉带where只会删除满足条件的数据 3.更新/修改数据
update 语法
update table_name
set 字段名1 值1, ....,字段名n 值n
where 条件;或
update table_name
set 字段名1 值1, ....,字段名n 值n示例
-- 不带where更新指定表中,字段所有的值
update test_user
set dept_id 2;
-- 带where更新满足条件的数据
update test_user
set dept_id 4,user_type 0, nick_name 测试账号3333
where user_name mytest3;4.查询数据
select 语法
-- 查询后展示指定的字段
select 字段名1,....,字段名n from table_name或
-- 查询后展示全部字段
select * from table_name示例
select user_id user_name,nick_name from test_user;
select * from test_user;4.1.where子句
在select的基础上加上条件进行条件筛选查询满足条件的数据 语法
select 字段1,....,字段n from table_name
where 条件;示例
-- 查询user_id1的数据展示全部字段
select * from test_user
where user_id 1;常用的条件运算符 等于 !不等于 大于 小于 小于等于 大于等于 between…and …在两值之间 not between不在两值之间 in在集合中 not in不在集合中 like模糊匹配 is null为空 is not null不为空 and条件组合和 or条件组合或 示例between…and
-- 查询user_id在1-3之间的
select * from test_user
where user_id between 1 and 3;示例not between
-- 查询user_id不在1-3之间的
select * from test_user
where user_id not between 1 and 3;示例in
-- 查询user_id是1、3、4的
select * from test_user
where user_id in(1,3,4);示例not in
-- 查询user_id不是1、3、4的
select * from test_user
where user_id not in(1,3,4);示例like
-- 模糊查询user_name
select * from test_user
-- user_name以my开头的
-- where user_name like my% ;-- user_name包含test的
-- where user_name like %test% ;-- user_name以test1结尾的
where user_name like %test1 ;示例is null
-- email是null的
select * from test_user
where email is null;示例is not null
-- email不是null的
select * from test_user
where email is not null;示例and
-- 查询user_id1且dept_id 1的
select * from test_user
where user_id 1 and dept_id 1 ;示例or
-- 查询user_id1或者dept_id 2的
select * from test_user
where user_id 1 or dept_id 2 ;4.2.order by
对数据排序 语法 order by 字段名1,...字段名n desc; 或 order by 字段名1,...字段名n asc; 示例desc – 降序
select * from test_menu
order by menu_id desc;示例asc – 升序
-- 默认asc排序
select * from test_menu
order by menu_id asc;4.3.limit与offset
limit返回指定的行数 offset与limit结合起来使用跳过指定的行数 语法 limit 行数 或 limit 行数 offset 行数
示例
-- 返回数据前3条
select * from test_menu
limit 3;-- 跳过返回的前3条数据
select * from test_menu
limit 3 offset 7;-- 可以结合起来使用menu_id倒序跳过前7条数据后返回前三条
select * from test_menu
order by menu_id desc
limit 3 offset 7;4.4.分组与having
group by分组通常与聚合函数一起使用对每个分组进行计算 having过滤分组后的数据 语法
select 列名1,....列名n,function(列名) from table_name
group by 列名1,....列名n
having 条件示例
-- 加上having则查询角色id为1的关联的菜单总数
select role_id,count(menu_id) from test_role_menu
group by role_id
having role_id 1或
-- 不加having查询每个角色id关联的菜单总数
select role_id,count(menu_id) from test_role_menu
group by role_id常用的聚合函数 SUM求和 AVG求平均值 COUNT求总数 MIN求最小值 MAX求最大值 4.5.连接
left join ... no 左连接左表返回所有记录右表返回满足条件的记录 语法
select 字段1,...,字段n from table_name1
left join table_name2 no 条件;示例
-- 连接test_role和test_role_menu表查询每个role_id的关联菜单总数左表数据全部返回
select role_name,coun_role.coun from test_role
left join
(select role_id,count(menu_id) as coun from test_role_menu
group by role_id) as coun_role
on coun_role.role_id test_role.role_id;right join....no 右连接右表返回所有记录左表返回满足条件的记录 语法
select 字段1,...,字段n from table_name1
right join table_name2 no 条件;示例
-- 连接test_role和test_role_menu表查询每个role_id的关联菜单总数右表数据全部返回
select role_name,coun_role.coun from test_role
right join
(select role_id,count(menu_id) as coun from test_role_menu
group by role_id) as coun_role
on coun_role.role_id test_role.role_id;inner join....no 内连接返回满足连接条件的记录 语法
select 字段1,...,字段n from table_name1
inner join table_name2 no 条件;示例
-- 连接test_role和test_role_menu表查询每个test_role.role_idtest_role_menu.role_id
-- 即角色关联了菜单的菜单总数
select role_name,coun_role.coun from test_role
inner join
(select role_id,count(menu_id) as coun from test_role_menu
group by role_id) as coun_role
on coun_role.role_id test_role.role_id;如图 5.创建表
create table 语法
create table table_name (字段名1 类型(长度) 约束,...., 字段名n 类型(长度) 约束, primary key (字段名1,...,字段名n)
);提示约束是可选的根据实际情况的需要决定是否需要加常见的有 not null非空约束指示某列不能存储 null值 unique唯一约束保证某列的每行必须有唯一的值 primary key主键约束not null 和unique的结合确保某列有唯一标识 foreign key外键约束保证参照完整性一个表中的数据匹配另一个表中的值 check检查约束保证列中的值符合指定的条件 default设置默认值没有给列赋值时的默认值 comment是注释可以理解为写个备注描述字段是干什么的我这里为了演示加上了 示例
create table test_user(user_id bigint(20) not null auto_increment comment 用户id,dept_id bigint(20) comment 部门id,user_name varchar(30) not null comment 用户账号,nick_name varchar(30) not null comment 用户昵称,user_type varchar(2) comment 用户类型,email varchar(50) COMMENT 用户邮箱,phonenumber varchar(11) COMMENT 手机号码,sex char(1) COMMENT 用户性别,password varchar(100) COMMENT 密码,status char(1) COMMENT 帐号状态,remark varchar(500) COMMENT 备注,primary key (user_id)
