最好的方法是在表中的列上创建全文索引 用contains代替LIKE

SELECT * FROM MyTable WHERE 
contains(Column1, N'word1')
AND contains(Column1, N'word2')
AND contains(Column1, N'word3')

select * from table where name regexp '^word[1-3]$'

or

select * from table where name in ('word1','word2','word3')

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;

DECLARE @SearchStr nvarchar(100)
SET @SearchStr = ' '



CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

SET NOCOUNT ON

DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
SET  @TableName = ''
SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

WHILE @TableName IS NOT NULL

BEGIN
    SET @ColumnName = ''
    SET @TableName = 
    (
        SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))
        FROM     INFORMATION_SCHEMA.TABLES
        WHERE         TABLE_TYPE = 'BASE TABLE'
            AND    QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName
            AND    OBJECTPROPERTY(
                    OBJECT_ID(
                        QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
                         ), 'IsMSShipped'
                           ) = 0
    )

    WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)

    BEGIN
        SET @ColumnName =
        (
            SELECT MIN(QUOTENAME(COLUMN_NAME))
            FROM     INFORMATION_SCHEMA.COLUMNS
            WHERE         TABLE_SCHEMA    = PARSENAME(@TableName, 2)
                AND    TABLE_NAME    = PARSENAME(@TableName, 1)
                AND    DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar', 'int', 'decimal')
                AND    QUOTENAME(COLUMN_NAME) > @ColumnName
        )

        IF @ColumnName IS NOT NULL

        BEGIN
            INSERT INTO #Results
            EXEC
            (
                'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630) FROM ' + @TableName + ' (NOLOCK) ' +
                ' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
            )
        END
    END   
END

SELECT ColumnName, ColumnValue FROM #Results

DROP TABLE #Results

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。

最好的方法是在表中的列上创建全文索引 用contains代替LIKE

SELECT * FROM MyTable WHERE 
contains(Column1, N'word1')
AND contains(Column1, N'word2')
AND contains(Column1, N'word3')
