Mysql Where ... in ... AND where ... in ...应该只在同一索引上匹配 [英] Mysql Where ... In ... AND where ... in ... should only match on same index

问题描述

我有一个查询:

SELECT * FROM `users` 
WHERE (`firstname` LIKE 'Luke' AND `lastname` LIKE 'Skywalker') OR  
 (`firstname` LIKE 'Foo' AND `lastname` LIKE 'Bar') OR 
(`firstname` LIKE 'Tom' AND `lastname` LIKE 'Turner');

但是我想通过在...中使用where ...使其更具可读性. 我尝试过

But i would like to make it a bit more readable by using a where ... in ... I tried

SELECT * FROM users 
WHERE `firstname` 
    IN ('Luke','Foo','Tom') AND `lastname` IN ('Skywalker','Bar','Turner');

但是不幸的是，它也可以匹配"Tom Skywalker"，"Foo Turner"以及您可以考虑的所有混合音.

But unfortunately this will also match "Tom Skywalker", "Foo Turner" and all mixes you can think off.

由于我要从外部API获取数据，并且必须检查这些名称是否在我们的系统中，因此我必须选择名字和姓氏(也许还有DOB之类的其他字段).

I have to select on first and lastname (perhaps more fields like DOB) since i am getting data from an external API and i have to check if those names are in our system.

推荐答案

SELECT * 
FROM users
WHERE (firstname, lastname) 
      IN ( ('Luke', 'Skywalker') 
         , ('Foo' , 'Bar') 
         , ('Tom' , 'Turner')
         )
;
