如何在MySQL中搜索多个列？ [英] How to search multiple columns in MySQL?

问题描述

我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。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%;

仅用于搜索一列，我注意到用逗号分隔列名会导致错误。那么是否有可能在mysql中搜索多个列？

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，具体取决于您想要的内容搜索返回。

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%;

如果两个子句匹配，则记录将被返回。

If either clause matches then the record will be returned.
