[英]MYSQL - insert into table or update if anything is different
Okey, so im trying to store the logged in facebook user´s friends list into a MYSQL table. Okey,所以我试图将登录的facebook用户好友列表存储到MYSQL表中。
Im storing the logged in user data: ID and Name; 我存储登录的用户数据:ID和名称; And am storing the logged in user friends list: ID and Name; 并存储登录的用户好友列表:ID和Name;
So the table looks like this: 所以表格如下:
['facebook_user_id'] ['facebook_user_name'] ['facebook_friend_id'] ['facebook_friend_name']
123123123123 User1 23424234234234 User 20
231321231231 User2 23424234234234 User 20
So you can see that user1 and user2 has the same friend and if user friend 'User 20' change his/her name I need to update the information, but only for the logged in user, so if user1 logs in the effect will only effect him/her. 所以你可以看到user1和user2有相同的朋友,如果用户朋友'User 20'更改了他/她的名字,我需要更新信息,但仅限登录用户,所以如果user1登录效果只会影响他她。
But if user1 gets a new friend I need to insert the new friend and update if theres any changes. 但是如果user1得到一个新朋友,我需要插入新朋友并更新,如果有任何变化。
How should I do this with PHP? 我应该如何用PHP做到这一点? I have seen something similar but didnt work that well for me. 我见过类似的东西,但对我来说效果不好。
INSERT INTO table (facebook_user_id, facebook_user_name, facebook_friend_id, facebook_friend_name)
VALUES ('facebook_user_id' (to short it down) .....)
ON DUPLICATE KEY UPDATE (facebook_user_id=facebook_user_id (and for every entry)....)
Thanks in advance, and any pointers will help me out alot. 在此先感谢,任何指针将帮助我很多。
I think this is what you meant. 我想这就是你的意思。 I am trying to save user A
Facebook friends into a table. 我正在尝试将用户A
Facebook朋友保存到表格中。 When someone logs in with Facebook I am storing, their name and Facebook id. 当有人使用Facebook登录时,我正在存储,他们的名字和Facebook ID。 As well as their friends, Facebook id and name. 以及他们的朋友,Facebook的ID和名字。
This is how I would do it. 我就是这样做的。 Here is my solution if you need generated schema code let me know. 如果您需要生成的架构代码,请告诉我,这是我的解决方案。
- Create three tables: registered users, buddies, lookup table - 创建三个表:注册用户,好友,查找表
table 1: registered users 表1:注册用户
[id, userId, facebookUid]
table 2: buddies 表2:伙计们
[id, buddyid, buddy name]
table 3: You need a lookup table. 表3:您需要一个查找表。
[id, userId, buddyid]
Steps: 脚步:
UserA
logs in with Facebook, save their buddies into the buddies
table 当UserA
使用Facebook登录时,将他们的好友保存到buddies
表中 join
to find who has buddies in common. 您可以使用join
来查找谁有共同的好友。
