1.2mysql常见操作命令

1)建表语句：在文章末尾

2)简单操作，增删查改单表

#SELECT * FROM cas_user where user_name="admin"
#INSERT INTO cas_user (user_name,pass_word)values("test1","123456"),("test2","123456");
#DELETE FROM cas_user WHERE user_name="test1";
#UPDATE cas_user SET user_name="updateName" where id=5;

3)复杂操作:多表操作

关联表的增、删、改一般利用事物控制，关联表的查询根据查询条件不同，查询语句也不同。

#内连接
#SELECT * FROM sys_user u INNER JOIN sys_user_role ur ON u.user_id=ur.user_id where u.user_id=238
#上面的内连接相当于where关联查询
#SELECT u.*,ur.id,ur.role_id FROM sys_user u ,sys_user_role ur WHERE u.user_id=ur.user_id 
#左连接
#SELECT u.* ,ur.id,ur.role_id FROM sys_user u LEFT JOIN sys_user_role ur ON u.user_id=ur.user_id
#右连接
#SELECT u.user_id ,ur.* FROM sys_user u RIGHT JOIN sys_user_role ur ON u.user_id=ur.user_id

4)用户-角色-权限表查询

####1、查询用户的角色及权限信息-- 
########连接三个数据表的用法：FROM (表1 INNER JOIN 表2 ON 表1.字段号=表2.字段号) INNER JOIN 表3 ON 表1.字段号=表3.字段号
-- 
--  SELECT u.*,r.*,p.* FROM sys_user u inner join sys_user_role ur on ur.user_id=u.user_id 
--  inner join sys_role r on r.role_id=ur.role_id INNER JOIN sys_role_permission rp on rp.role_id=r.role_id
--  INNER JOIN sys_permission p on p.perm_id=rp.perm_id WHERE user_name='admin';

####2、查询某用户的角色
-- SELECT u.*,r.* FROM sys_user u,sys_role r,sys_user_role ur WHERE u.user_name='admin' AND u.user_id=ur.user_id AND ur.role_id=r.role_id;

####3、查询某用户拥有的权限
-- SELECT p.* FROM sys_permission p,sys_role_permission rp,sys_role r WHERE r.role_id=rp.role_id AND rp.perm_id=p.perm_id AND  r.role_id
-- IN (SELECT r.role_id FROM sys_user u,sys_role r,sys_user_role ur WHERE u.user_name ='admin' AND u.user_id=ur.user_id AND ur.role_id=r.role_id);
####4、查询拥有某角色的用户信息
 #SELECT u.* FROM sys_user u,sys_role r,sys_user_role ur WHERE r.role_id=1 AND  r.role_id=ur.role_id AND ur.user_id=u.user_id;
####5、查询拥有某权限的角色
--  SELECT p.`perm_name`,r.`role_name` FROM sys_permission p,sys_role_permission rp,sys_role r WHERE p.`perm_name`='query' AND p.perm_id=rp.perm_id AND rp.role_id=r.role_id;
####6、查询某角色拥有的权限
-- SELECT p.* FROM sys_permission p,sys_role_permission rp,sys_role r WHERE r.role_id=rp.role_id AND rp.perm_id=p.perm_id AND  r.role_id
-- IN (SELECT r.role_id FROM sys_user u,sys_role r,sys_user_role ur WHERE u.user_name ='user1' AND u.user_id=ur.user_id AND ur.role_id=r.role_id);
