问题描述
我正在尝试制作一个搜索功能，该功能将搜索多个列以查找基于关键字的匹配项.此查询:
I'm trying to make a search feature that will search multiple columns to find a keyword based match. This query:
SELECT title FROM pages LIKE %$query%;
仅适用于搜索一列，我注意到用逗号分隔列名会导致错误.那么可以在mysql中搜索多列吗?
works only for searching one column, I noticed separating column names with commas results in an error. So is it possible to search multiple columns in mysql?
推荐答案
您可以使用 AND 或 OR 运算符，具体取决于您希望搜索返回的内容.
You can use the AND or OR operators, depending on what you want the search to return.
SELECT title FROM pages WHERE my_col LIKE %$param1% AND another_col LIKE %$param2%;
两个子句都必须匹配才能返回记录.或者:
Both clauses have to match for a record to be returned. Alternatively:
SELECT title FROM pages WHERE my_col LIKE %$param1% OR another_col LIKE %$param2%;
如果任何一个子句匹配，那么记录将被返回.
If either clause matches then the record will be returned.
