LIKE 查询按列最佳匹配

Question

我有一个名为 customers 和运行的 table 查询，如下所示

SELECT * FROM customers WHERE email LIKE '%ab%' OR first_name LIKE '%ab%';

结果如下

------+-------+-------+------- +
|      email    | first_name   |
+-----+-------+-------+------- +
| abc@gmail.com |   xyz        |
| xyz@gmail.com |   abc        |
+-----+-------+-------+--------+

我需要的是，first_name是搜索关键词的最佳匹配。所以我首先需要那一行。

Answer 1

您可能希望通过以下方式添加订单：

SELECT * 
FROM customers 
WHERE email LIKE '%ab%' OR first_name LIKE '%ab%'
ORDER BY CASE WHEN first_name LIKE '%ab%' THEN 1 ELSE 2 END;
