有没有办法创建用户特定的表；“指针”；在MySQL中？ 问题:

有没有一种方法可以让用户的视图

PERSON

指向某个主要的PERSON表，让我们称之为

main\u PERSON

，也可以为用户

jill

创建一个视图

PERSON

，并让它指向同一个

main\u PERSON

表，区别在于，杰克只能接近男人，吉尔只能接近女人

细节： 下面是我想如何设置我的表/视图

人员表：

CREATE TABLE IF NOT EXISTS person
(
   id            INT NOT NULL auto_increment,
   male          BOOLEAN,

   PRIMARY KEY(id)
)
engine=innodb;

CREATE VIEW person_for_jacks_eyes_only
AS
SELECT * FROM person
WHERE
person.male = TRUE;

CREATE VIEW person_for_jills_eyes_only
AS
SELECT * FROM person
WHERE
person.male = false;

GRANT SELECT ON DB.person_for_jacks_eyes_only TO jack@'localhost' IDENTIFIED BY '1234';
GRANT SELECT ON DB.person_for_jills_eyes_only TO jill@'localhost' IDENTIFIED BY '1234';

杰克的视图：

CREATE TABLE IF NOT EXISTS person
(
   id            INT NOT NULL auto_increment,
   male          BOOLEAN,

   PRIMARY KEY(id)
)
engine=innodb;

CREATE VIEW person_for_jacks_eyes_only
AS
SELECT * FROM person
WHERE
person.male = TRUE;

CREATE VIEW person_for_jills_eyes_only
AS
SELECT * FROM person
WHERE
person.male = false;

GRANT SELECT ON DB.person_for_jacks_eyes_only TO jack@'localhost' IDENTIFIED BY '1234';
GRANT SELECT ON DB.person_for_jills_eyes_only TO jill@'localhost' IDENTIFIED BY '1234';

吉尔的视图：

CREATE TABLE IF NOT EXISTS person
(
   id            INT NOT NULL auto_increment,
   male          BOOLEAN,

   PRIMARY KEY(id)
)
engine=innodb;

CREATE VIEW person_for_jacks_eyes_only
AS
SELECT * FROM person
WHERE
person.male = TRUE;

CREATE VIEW person_for_jills_eyes_only
AS
SELECT * FROM person
WHERE
person.male = false;

GRANT SELECT ON DB.person_for_jacks_eyes_only TO jack@'localhost' IDENTIFIED BY '1234';
GRANT SELECT ON DB.person_for_jills_eyes_only TO jill@'localhost' IDENTIFIED BY '1234';

创建用户并授予特权：

CREATE TABLE IF NOT EXISTS person
(
   id            INT NOT NULL auto_increment,
   male          BOOLEAN,

   PRIMARY KEY(id)
)
engine=innodb;

CREATE VIEW person_for_jacks_eyes_only
AS
SELECT * FROM person
WHERE
person.male = TRUE;

CREATE VIEW person_for_jills_eyes_only
AS
SELECT * FROM person
WHERE
person.male = false;

GRANT SELECT ON DB.person_for_jacks_eyes_only TO jack@'localhost' IDENTIFIED BY '1234';
GRANT SELECT ON DB.person_for_jills_eyes_only TO jill@'localhost' IDENTIFIED BY '1234';

动机：

我想让不同的用户只访问行的子集。据我所知，这是视图的目的之一（另一个目的是将多个表组合在一起）。一、 但是，我不希望使用模糊的视图名称，例如仅用于_jacks\u eyes\u的，因此我希望使用特定于用户的本地名称。如果这是使用视图的错误方式，请有人帮我指出正确的方向。

不，没有。表和视图只有一个全局名称空间；无法使用相同的名称创建多个视图

但是，我相信您可以声明一个视图，其输出取决于当前用户：

CREATE VIEW limited_person AS
    SELECT * FROM person
    WHERE person.male = (USER() = 'jack@localhost')

谢谢，这将是我的下一个问题：

USER（）。
