MYSQL - 多个不起作用

Question

我有一个包含Businesses的数据库，我想在一系列邮政编码中查询所有具有特定名称的商家。

例如：

business_name = KFC

postcode =`[N1，N17，N18，BN1]

我尝试了以下查询：

SELECT * FROM businesses WHERE business_name = 'KFC' AND postcode LIKE '%N1%' OR postcode LIKE '%N17%' OR postcode LIKE '%N18%' OR postcode LIKE '%BN1'

问题在于它带回了拥有此邮政编码但却与KFC无关的企业。任何人都可以提出理由和我应该做的事情吗？

Answer 1

尝试这种方式：

 SELECT * FROM businesses WHERE business_name = 'KFC' AND (postcode LIKE '%N1%' OR postcode LIKE '%N17%' OR postcode LIKE '%N18%' OR postcode LIKE '%BN1')
