MySql在特定字符之前是什么样的？

Question

我必须从两列中搜索特定单词，但在一列中我必须在*字符之前搜索。所以我现在使用SELECT * FROM table_name WHERE status = 'Enable' AND topic LIKE '%car%' OR category LIKE '%car%'问题是它返回了美容专栏，因为它的类别栏中有 car e这个词，现在我必须在第一个*之前包含该词回来。

+--------+---------------------------------------------------------------------------+---------+
| topic  | category                                                                  | status  |
+--------+---------------------------------------------------------------------------+---------+
| car    | cars & vechicles*cars*                                                    | Enabled |
+--------+---------------------------------------------------------------------------+---------+
| beauty | Fashion, Health & Beauty*Health and Beauty Products*Body Care / Skin Care | Enabled |
+--------+---------------------------------------------------------------------------+---------+

Answer 1

此查询应解决您的问题：

SELECT * FROM table_name WHERE 
status = 'Enable' AND topic LIKE '%car%' OR SUBSTRING_INDEX(category,'*',1) LIKE '%car%'

Answer 2

您可以添加＆＃34;％*＆＃34;对您的查询进行简单修改。像这样：

SELECT * FROM table_name WHERE status = 'Enable' AND topic LIKE '%car%' OR category LIKE '%car%*%'
