MySQL IN()有两个值/数组吗? [英] MySQL IN() for two value/array?

问题描述

我在寻找一种更好的方法来搜索MySQL以查找表中的一对值时遇到了麻烦.我将值对放在一个数组中，想复制IN()函数，但要使用多个值.

I'm having trouble finding a better way to search MySQL for a pair of values in a table. I have the value pairs in an array, and would like to duplicate the IN() function, but for more than 1 value.

例如用于目标；我有以下3对:

For example purposed; I have the following 3 pairs:

foo,1
boo,2
goo,3

当前的解决方案使我处于:

The current solution puts me at:

SELECT * FROM [table] WHERE 
(column1 = 'foo' AND column2 = 1) OR
(column1 = 'boo' AND column2 = 2) OR
(column1 = 'goo' AND column2 = 3);

我想想有一种更性感"的解决方案，因为我可以拥有多达一百对，而OR会让我恶心.谢谢!!!

I'd like to think there's a more "sexy" solution seeing that I could have as many as a hundred pairs and having that may ORs kind of makes me nauseous. Thanks!!!

推荐答案

SELECT  *
FROM    foo
WHERE   (column1, column2) IN (('foo', 1), ('bar', 2))

此语法可能会造成混淆，并且用以下内容替换可能更容易理解:

This syntax may be confusing, and it may be more readable to replace it with:

SELECT  *
FROM    foo
WHERE   ROW(column1, column2) IN (ROW('foo', 1), ROW('bar', 2))

我已经习惯了前一个，:)

I'm used to the former one, though :)
