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

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…

这很有帮助。我想把这个函数导入到Postgre SQL数据库。我想把它分享给感兴趣的人。会有几个小时。注意:这个函数创建了一个SQL语句列表，可以在Postgre数据库上复制和执行。也许比我聪明的人可以让Postgre在一个函数中创建并执行所有语句。

CREATE OR REPLACE FUNCTION SearchAllTables(_search text) RETURNS TABLE( txt text ) as $funct$
    DECLARE __COUNT int;
    __SQL text;
BEGIN
    EXECUTE 'SELECT COUNT(0) FROM INFORMATION_SCHEMA.COLUMNS
                    WHERE    DATA_TYPE = ''text'' 
                    AND          table_schema = ''public'' ' INTO __COUNT;

    RETURN QUERY 
        SELECT CASE WHEN ROW_NUMBER() OVER (ORDER BY table_name) < __COUNT THEN 
            'SELECT ''' || table_name ||'.'|| column_name || ''' AS tbl, "'  || column_name || '" AS col FROM "public"."' || "table_name" || '" WHERE "'|| "column_name" || '" ILIKE ''%' || _search  || '%'' UNION ALL' 
            ELSE 
            'SELECT ''' || table_name ||'.'|| column_name || ''' AS tbl, "'  || column_name || '" AS col FROM "public"."' || "table_name" || '" WHERE "'|| "column_name" || '" ILIKE ''%' || _search  || '%'''
        END AS txt

                    FROM     INFORMATION_SCHEMA.COLUMNS
                    WHERE    DATA_TYPE = 'text' 
                    AND          table_schema = 'public';
END
$funct$ LANGUAGE plpgsql;

不要忽略@Brandon的精彩回答，但OP要求“结果应该显示表及其各自的行”。我基于来自@Brandon的原始答案创建了一个记录级解决方案，该解决方案还通过简单地将所有适当的列连接到一个字符串中来避免使用其他人在这里使用的游标。(我感觉这样做会更好，但我真的没有比较过结果-请随意这样做并在这里提供反馈。)

注意，我使用了STRING_AGG函数来连接列。如果你使用的是旧版本的SQL Server，你可能需要使用可以在网上找到的替代方法之一。

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:
