Question

我想从字符串中搜索确切的单词，如

id  Description
1   This is nice pen looking good
2   This is nice pendrive looking good

搜索字符串：pen

我当前的查询

SELECT * FROM `table` WHERE Description like '%pen%';

以上查询返回两个记录，但我想只有第一个记录。因为笔字与我的搜索字符串完全匹配。

预期输出

1   This is nice pen looking good

Answer 1

尝试使用正则表达式：

SELECT 
    *
FROM
    `table`
WHERE
    Description regexp '(^|[[:space:]])pen([[:space:]]|$)';

或使用word boundaries：

SELECT 
    *
FROM
    `table`
WHERE
    Description regexp '[[:<:]]pen[[:>:]]';

Answer 2

您可以使用REGEXP以及[[:<:]]和[[:>:]]字边界标记：

SELECT
    *
FROM
    `table`
WHERE
    Description REGEXP '[[:<:]]pen[[:>:]]';

Answer 3

您可以使用全文匹配，如下所示

Request failed: Could not load file or assembly 'PerformanceTestingUtilities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

您也可以选择布尔模式，它会在搜索结果中返回准确的单词
