mysql之基本常用的语法
- 1.增加数据
- 2.删除数据
- 3.更新/修改数据
- 4.查询数据
- 4.1.where子句
- 4.2.order by
- 4.3.limit与offset
- 4.4.分组与having
- 4.5.连接
- 5.创建表
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)
);
