如何在没有union的情况下优化以下查询顺序

Question

我需要一个逻辑来根据字符串搜索列。

考虑以下查询。在下面的查询中，我想在customer表中搜索字符串'test'。如果在客户名称列中找到它，则需要位于顶部，然后是基于customer_slug找到的列

SELECT * FROM `customer_list` WHERE customer_name = 'test' UNION
SELECT * FROM `customer_list` WHERE customer_slug = 'test'

Answer 1

SELECT * FROM customer_list 
where 'test' in (customer_name, customer_slug)
order by 'test' <> customer_name,
         'test' <> customer_slug

Answer 2

"URL with ' "
