更新TechDo对SQL server 2012的答案。你需要更改:'FROM ' + @TableName + ' (NOLOCK)+ @TableName + 'WITH (NOLOCK)' +

在这个版本的SQL Server中不支持已弃用的功能“不带WITH的表提示”。

下面是更新后的完整存储过程:

CREATE PROC SearchAllTables
(
@SearchStr nvarchar(100)
)
AS
BEGIN

    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 + 'WITH (NOLOCK) ' +
                    ' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
                )
            END
        END    
    END

    SELECT ColumnName, ColumnValue FROM #Results
END

我已经为这个写了一个SP，它以表名的形式返回搜索结果，在其中找到搜索关键字字符串的列名以及搜索对应的行，如下面的屏幕截图所示。

这可能不是最有效的解决方案，但您可以根据需要随时修改和使用它。

IF OBJECT_ID('sp_KeywordSearch', 'P') IS NOT NULL
    DROP PROC sp_KeywordSearch
GO

CREATE PROCEDURE sp_KeywordSearch @KeyWord NVARCHAR(100)
AS
BEGIN
    DECLARE @Result TABLE
        (TableName NVARCHAR(300),
         ColumnName NVARCHAR(MAX))

    DECLARE @Sql NVARCHAR(MAX),
        @TableName NVARCHAR(300),
        @ColumnName NVARCHAR(300),
        @Count INT

    DECLARE @tableCursor CURSOR

    SET @tableCursor = CURSOR LOCAL SCROLL FOR
    SELECT  N'SELECT @Count = COUNT(1) FROM [dbo].[' + T.TABLE_NAME + '] WITH (NOLOCK) WHERE CAST([' + C.COLUMN_NAME +
            '] AS NVARCHAR(MAX)) LIKE ''%' + @KeyWord + N'%''',
            T.TABLE_NAME,
            C.COLUMN_NAME
    FROM    INFORMATION_SCHEMA.TABLES AS T WITH (NOLOCK)
    INNER JOIN INFORMATION_SCHEMA.COLUMNS AS C WITH (NOLOCK)
    ON      T.TABLE_SCHEMA = C.TABLE_SCHEMA AND
            T.TABLE_NAME = C.TABLE_NAME
    WHERE   T.TABLE_TYPE = 'BASE TABLE' AND
            C.TABLE_SCHEMA = 'dbo' AND
            C.DATA_TYPE NOT IN ('image', 'timestamp')

    OPEN @tableCursor
    FETCH NEXT FROM @tableCursor INTO @Sql, @TableName, @ColumnName

    WHILE (@@FETCH_STATUS = 0)
    BEGIN
        SET @Count = 0

        EXEC sys.sp_executesql
            @Sql,
            N'@Count INT OUTPUT',
            @Count OUTPUT

        IF @Count > 0
        BEGIN
            INSERT  INTO @Result
                    (TableName, ColumnName)
            VALUES  (@TableName, @ColumnName)
        END

        FETCH NEXT FROM @tableCursor INTO @Sql, @TableName, @ColumnName
    END

    CLOSE @tableCursor
    DEALLOCATE @tableCursor

    SET @tableCursor = CURSOR LOCAL SCROLL FOR
    SELECT  SUBSTRING(TB.Sql, 1, LEN(TB.Sql) - 3) AS Sql, TB.TableName, SUBSTRING(TB.Columns, 1, LEN(TB.Columns) - 1) AS Columns
    FROM    (SELECT R.TableName, (SELECT R2.ColumnName + ', ' FROM @Result AS R2 WHERE R.TableName = R2.TableName FOR XML PATH('')) AS Columns,
                    'SELECT * FROM ' + R.TableName + ' WITH (NOLOCK) WHERE ' +
                    (SELECT 'CAST(' + R2.ColumnName + ' AS NVARCHAR(MAX)) LIKE ''%' + @KeyWord + '%'' OR '
                     FROM   @Result AS R2
                     WHERE  R.TableName = R2.TableName
                    FOR
                     XML PATH('')) AS Sql
             FROM   @Result AS R
             GROUP BY R.TableName) TB
    ORDER BY TB.Sql

    OPEN @tableCursor
    FETCH NEXT FROM @tableCursor INTO @Sql, @TableName, @ColumnName

    WHILE (@@FETCH_STATUS = 0)
    BEGIN
        PRINT @Sql
        SELECT  @TableName AS [Table],
                @ColumnName AS Columns
        EXEC(@Sql)

        FETCH NEXT FROM @tableCursor INTO @Sql, @TableName, @ColumnName
    END

    CLOSE @tableCursor
    DEALLOCATE @tableCursor

END

不需要嵌套循环(遍历表的外部循环和遍历所有表列的内部循环)。可以从INFORMATION_SCHEMA中检索所有(或任意选择/筛选的)表-列组合。COLUMNS和在一个循环中简单地遍历(搜索)所有它们:

DECLARE @search VARCHAR(100), @table SYSNAME, @column SYSNAME

DECLARE curTabCol CURSOR FOR
    SELECT c.TABLE_SCHEMA + '.' + c.TABLE_NAME, c.COLUMN_NAME
    FROM INFORMATION_SCHEMA.COLUMNS c
    JOIN INFORMATION_SCHEMA.TABLES t 
      ON t.TABLE_NAME=c.TABLE_NAME AND t.TABLE_TYPE='BASE TABLE' -- avoid views
    WHERE c.DATA_TYPE IN ('varchar','nvarchar') -- searching only in these column types
    --AND c.COLUMN_NAME IN ('NAME','DESCRIPTION') -- searching only in these column names

SET @search='john'

OPEN curTabCol
FETCH NEXT FROM curTabCol INTO @table, @column

WHILE (@@FETCH_STATUS = 0)
BEGIN
    EXECUTE('IF EXISTS 
             (SELECT * FROM ' + @table + ' WHERE ' + @column + ' = ''' + @search + ''') 
             PRINT ''' + @table + '.' + @column + '''')
    FETCH NEXT FROM curTabCol INTO @table, @column
END

CLOSE curTabCol
DEALLOCATE curTabCol

有点晚了，但希望有用。

为什么不尝试一些可以集成到SSMS中的第三方工具呢?

我使用过ApexSQL Search(100%免费)，在模式和数据搜索方面都取得了很好的成功，还有SSMS工具包也有这个功能(SQL 2012不是免费的，但相当实惠)。

上面的存储过程真的很棒;只是在我看来这样更方便。此外，如果你想搜索datetime列或GUID列等，它将需要一些轻微的修改…

有点晚了，但是您可以很容易地用这个查询找到一个字符串

DECLARE
@search_string  VARCHAR(100),
@table_name     SYSNAME,
@table_id       INT,
@column_name    SYSNAME,
@sql_string     VARCHAR(2000)

SET @search_string = 'StringtoSearch'

DECLARE tables_cur CURSOR FOR SELECT ss.name +'.'+ so.name [name], object_id FROM sys.objects so INNER JOIN sys.schemas ss ON so.schema_id = ss.schema_id WHERE  type = 'U'

OPEN tables_cur

FETCH NEXT FROM tables_cur INTO @table_name, @table_id

WHILE (@@FETCH_STATUS = 0)
BEGIN
    DECLARE columns_cur CURSOR FOR SELECT name FROM sys.columns WHERE object_id = @table_id 
        AND system_type_id IN (167, 175, 231, 239)

    OPEN columns_cur

    FETCH NEXT FROM columns_cur INTO @column_name
        WHILE (@@FETCH_STATUS = 0)
        BEGIN
            SET @sql_string = 'IF EXISTS (SELECT * FROM ' + @table_name + ' WHERE [' + @column_name + '] 
            LIKE ''%' + @search_string + '%'') PRINT ''' + @table_name + ', ' + @column_name + ''''

            EXECUTE(@sql_string)

        FETCH NEXT FROM columns_cur INTO @column_name
        END

    CLOSE columns_cur

DEALLOCATE columns_cur

FETCH NEXT FROM tables_cur INTO @table_name, @table_id
END

CLOSE tables_cur
DEALLOCATE tables_cur
