通过搜索SQL Server Management Studio 2008中的所有表来查找字符串

207

有什么方法可以在SQL Server Management Studio 2008中在数据库的所有表中搜索字符串？

我想搜索字符串说john。结果应显示包含的表及其相应行john。

如果您像我一样，并且在生产环境中有某些限制，则可能希望使用表变量而不是临时表，并且使用临时查询而不是创建过程。

当然，取决于您的sql server实例，它必须支持表变量。

我还添加了USE语句来缩小搜索范围

USE DATABASE_NAME
DECLARE @SearchStr nvarchar(100) = 'SEARCH_TEXT'
DECLARE @Results TABLE (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(

                           ) = 0

太棒了 我添加了“ PRINT @TableName +'。” + @ColumnName”（第53行），因此它可以在大型数据库中正常工作。但这非常有帮助。

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。

我曾与 ApexSQL Search（100％免费），在模式和数据搜索方面都取得了成功，并且还有具有此功能的SSMS工具包（对于SQL 2012不是免费的，但价格合理）。

上面的存储过程确实很棒。我认为这只是更方便。另外，如果您要搜索datetime列或GUID列，则需要进行一些细微修改，例如……

要更新TechDo的用于SQL Server 2012的答案你需要改变：'FROM ' + @TableName + ' (NOLOCK) ' 以 FROM ' + @TableName + 'WITH (NOLOCK) ' +

否则，您将得到以下错误： Deprecated feature 'Table hint without WITH' is not supported in this version of SQL Server.

下面是完整的更新的存储过程：

我为此编写了一个SP，该SP以表名，在其中找到搜索关键字字符串的列名以及搜索相应行的形式返回搜索结果，如下面的屏幕快照所示。

这可能不是最有效的解决方案，但是您始终可以根据需要进行修改和使用。

不需要嵌套循环（通过表的外部循环和通过所有表列的内部循环）。可以从INFORMATION_SCHEMA.COLUMNS一个循环中检索所有（或任意选择/过滤的）表-列组合，并且只需循环（搜索）所有它们即可：

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

我不知道您的意思，但是此查询工作正常。光标curTabCol选择感兴趣的所有table.column组合。然后在所有这些列中搜索变量@search中给定的字符串。如果此SQL查询中存在这样的字符串（精确）（否则使用LIKE'％...％'），则将打印出表名和列名的组合。

这非常有帮助。我想将此函数导入Postgre SQL数据库。以为我会与任何有兴趣的人分享。将有几个小时。注意：此函数创建一个SQL语句列表，可以在Postgre数据库上复制和执行该语句。也许有人那么聪明，我就可以让Postgre在一个函数中创建和执行所有语句。

        SELECT CASE WHEN ROW_NUMBER() OVER (ORDER BY table_name) < __COUNT THEN
