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。

Use:

SELECT * FROM MyTable WHERE Column1 Like "*word*"

这将显示column1的部分值包含word的所有记录。

配套功能

-- Split @str by @sep
-- Returns all parts
CREATE FUNCTION [dbo].[fnSplit] (
  @sep CHAR(1),
  @str VARCHAR(512)
) RETURNS TABLE AS RETURN (
  WITH Pieces(pn, start, stop) AS (
    SELECT
      1,
      1,
      CHARINDEX(@sep, @str)
    UNION ALL
    SELECT
      pn + 1,
      stop + 1,
      CHARINDEX(@sep, @str, stop + 1)
    FROM Pieces
    WHERE stop > 0
  )

  SELECT
    pn AS Id,
    SUBSTRING(@str, start, CASE
      WHEN stop > 0
      THEN stop - start
      ELSE 512
    END) AS Data
  FROM Pieces
)

查询示例

在MyTable中搜索单词word1, word2, word3。Column1:

-- Create a temporal table (the Data size depends on the length of the word)
DECLARE @FilterTable TABLE (Data VARCHAR(512))

-- Get different and unique words for the search
INSERT INTO @FilterTable (Data)
SELECT DISTINCT S.Data
FROM fnSplit(' ', 'word1 word2 word3') S -- Contains words

-- Search into "MyTable" by "Column1"
SELECT DISTINCT
  T.*
FROM
  MyTable T
  -- Matching records
  INNER JOIN @FilterTable F1 ON T.Column1 LIKE '%' + F1.Data + '%'
  -- Is some word not present?
  LEFT JOIN @FilterTable F2 ON T.Column1 NOT LIKE '%' + F2.Data + '%'
WHERE
  -- Is some word not present?
  F2.Data IS NULL;

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。

用"in"代替:

Select *
from table
where columnname in (word1, word2, word3)
