Mysql:按喜欢排序吗? [英] Mysql: Order by like?

问题描述

假设我们正在使用以下关键字进行搜索:keyword1，keyword2，keyword3

assume that we are performing search using keywords: keyword1, keyword2, keyword3

数据库中有名称"列的记录:

there are records in database with column "name":

1: John Doe
2: Samuel Doe
3: John Smith
4: Anna Smith

现在查询:

SELECT * FROM users WHERE (name LIKE "%John%" OR name LIKE "%Doe%")

它将选择记录:1,2,3(按此顺序) 但我想按关键字订购 在示例keyword1=John, keyword2=Doe 因此应按关键字列出:1、3、2(因为我想在搜索约翰"后执行对"Doe"的搜索)

it will select records: 1,2,3 (in this order) but i want to order it by keyword in example keyword1=John, keyword2=Doe so it should be listed by keywords: 1,3,2 (because i want to perform search for "Doe" after searching for "John")

我正在考虑SELECT DISTINCT FROM (...... UNION .....) 但是通过另一种方式订购它会容易得多(实际查询时间很长)

I was thinking about SELECT DISTINCT FROM (...... UNION .....) but it will be much easier to order it somehow in another way (real query is really long)

有什么技巧可以创建这样的订单?

are there any tricks to create such order?

推荐答案

order by case 
    when name LIKE "%John%" then 1 
    when name LIKE "%Doe%"  then 2 
    else 3 
end
