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

注意，如果使用LIKE来确定一个字符串是否是另一个字符串的子字符串，则必须转义搜索字符串中的匹配字符的模式。

如果你的SQL方言支持CHARINDEX，那么使用它会更容易:

SELECT * FROM MyTable
WHERE CHARINDEX('word1', Column1) > 0
  AND CHARINDEX('word2', Column1) > 0
  AND CHARINDEX('word3', Column1) > 0

另外，请记住，这和接受的答案中的方法只涵盖子字符串匹配，而不是单词匹配。因此，例如，字符串'word1word2word3'仍然会匹配。

将SELECT * FROM MyTable WHERE Column1 CONTAINS 'word1 word2 word3'替换为在这些单词之间添加And:

SELECT * FROM MyTable WHERE Column1 CONTAINS 'word1 And word2 And word3'

详细信息请参见CONTAINS (Transact-SQL)。

在选择短语时，使用双引号:

SELECT * FROM MyTable WHERE Column1 CONTAINS '"Phrase one" And word2 And "Phrase Two"'

附注:在使用contains关键字之前，您必须首先在表上启用全文检索。有关更多详细信息，请参见全文搜索入门。

如果使用SQL Server全文搜索，这应该在SQL Server全文搜索的帮助下理想地完成。

然而，如果你因为某些原因不能在你的DB上工作，这里有一个性能密集型的解决方案:

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

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。
