在MySQL数据库中存储位掩码值数组的最佳方法？

[英]Best way to store an array of bitmasked values in a MySQL database?

原文 2016-10-21 16:59:46 1 1 php/ mysql

I am using a bitmask value to store a list of possible people in a row (1=John, 2=Paul, 4=George, 8=Ringo, 16=Pete, etc.) and that's working just fine, but in a certain situation I need to store this value for each day of the week. 我正在使用一个位掩码值来连续存储一个可能的人的列表（1 = John，2 = Paul，4 = George，8 = Ringo，16 = Pete等），并且工作正常，但在一定程度上情况我需要在一周的每一天存储此值。

I can easily do it by creating columns for each day (peopleSun, peopleMon, peopleTue, etc.) since while the number of people could change, the number of days in a week won't. 我可以通过每天创建一列（peopleSun，peopleMon，peopleTue等）来轻松完成此操作，因为尽管人数可以更改，但一周中的天数不会更改。 But it feels so... dirty, like I should be more efficient with it somehow. 但这感觉真...很脏，就像我应该以某种方式更有效。

I'm using it in connection with PHP, and so I realize I could create an array and encode it using serialize(), but that feels like it makes the database less accessible in the future. 我将其与PHP结合使用，因此我意识到我可以创建一个数组并使用serialize（）对其进行编码，但是感觉这会使将来数据库的访问性降低。

Is there a better way of doing this, or should I just hardwire seven different columns and stop worrying about making my database ready to handle... eight days a week? 有没有更好的方法可以做到这一点，还是我应该只硬连接七个不同的列，而不必担心让我的数据库准备好……每周八天进行处理？ (ugh, sorry I didn't plan for that, it was just too good to pass up) （哦，对不起，我没有为此计划，实在太好了，无法通过）

Okay, I wasn't thinking with ~~portals~~ relational databases. 好的，我不是在考虑 ~~门户网站~~ 关系数据库。

I created a second table with columns "people", "day" (1=Sun, 2=Mon, etc), and "recordID" (which is tied to the id of the row in the other table. 我创建了第二个表，其中包含列“ people”，“ day”（1 = Sun，2 = Mon等）和“ recordID”（与另一个表中的行的ID关联）。

Sometimes you just need to let these things simmer for a weekend, I guess... 我想有时候有时候你只需要让这些东西一下就可以了。
