mysql之基本常用的语法
mysql之基本常用的语法
1.增加数据
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','3030@qq.com','18512345678','0','12345678','0','测试'),
(4,1,'mytest4','测试账号4','1','3031@qq.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_id=1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_id=1且,dept_id = 1的
select * from test_user
where user_id =1 and dept_id = 1 ;
示例:or
-- 查询user_id=1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_id=test_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)
);
相关表和数据:
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
