在MYSQL中搜索特定关键字

Question

我几乎是mysql的新手。

我想编写一个查询来搜索关键字以逗号分隔的列中的特定关键字。但是当我使用以下代码时，它只返回我只有那个特定关键字的行，而不是与任何其他关键字组合。

在表q16中，我正在寻找一种方法来选择在“Area_of_concern”列中包含我的关键字的行，无论它是否与其他关键字结合使用：

 SELECT * 
 FROM `q16` 
 WHERE area_of_concern like '%more education is needed%'

这是一个输入示例：

q16_id关注领域

1   more education is needed
2   more enforcement, change in strategy
3   change in strategy
4   more education is needed, change in strategy
5   transportation issue, more enforcement, more education is needed

我希望获得关键字“需要更多教育”的行。所以我应该在输出中看到第1,4,5行

Answer 1

I think you should create a table where you have one column for keywords and one column for where those keywords are used: a foreign key for the q16 table in your case.

It will work much faster that way.

As for your question it is a duplicate of this one here, I believe.

How to search for rows containing a substring?

A quick try: try using double quotes instead of single ones, as in some systems, single quotes don't allow for escapes (special characters) inside them.
