相当缓慢，但工作方法包括任何单词:

SELECT * FROM mytable
WHERE column1 LIKE '%word1%'
   OR column1 LIKE '%word2%'
   OR column1 LIKE '%word3%'

如果你需要所有的单词都出现，使用这个:

SELECT * FROM mytable
WHERE column1 LIKE '%word1%'
  AND column1 LIKE '%word2%'
  AND column1 LIKE '%word3%'

如果您想要更快，您需要研究全文搜索，这对于每种数据库类型都是非常特定的。

如果你只是想找到匹配。

SELECT * FROM MyTable WHERE INSTR('word1 word2 word3', Column1)<>0

SQL服务器:

CHARINDEX(Column1, 'word1 word2 word3', 1)<>0

得到精确匹配。例子:(ab;;;交流;,;b)将不会匹配。

SELECT * FROM MyTable WHERE INSTR(';word1;word2;word3;', ';'||Column1||';')<>0

实现问题中提到的最简单的方法之一是使用CONTAINS和NEAR或'~'。例如，下面的查询将为我们提供具体包括word1、word2和word3的所有列。

SELECT * FROM MyTable WHERE CONTAINS(Column1, 'word1 NEAR word2 NEAR word3')

SELECT * FROM MyTable WHERE CONTAINS(Column1, 'word1 ~ word2 ~ word3')

此外，CONTAINSTABLE根据“word1”、“word2”和“word3”的接近度为每个文档返回一个排名。例如，如果一个文档包含这样一句话，“word1是word2和word3”，那么它的排名就会很高，因为这些术语比其他文档中更接近彼此。

我们还可以使用proximity_term来查找单词位于列短语内它们之间的特定距离内的列。
