search数据库的所有表，行和列中的string
我迷失在一个大的数据库中，我无法find我得到的数据来自哪里。 我想知道是否有可能在SQL Server 2005中search数据库的所有表，行和列中的string？
有没有人有一个想法，如果有可能和如何？
这个代码应该在SQL 2005中做，但是有一些注意事项：
-
它很慢很慢。 我testing了一个小数据库，只有less数几个表，花了很多分钟才完成。 如果你的数据库太大，你不能理解，那么这可能无法使用。
-
我从袖口上写下来。 我没有进行任何error handling，特别是因为我经常不使用游标，所以可能会有其他的不合理之处。 例如，我认为有一种刷新列光标的方法，而不是每次closures/取消分配/重新创build它。
如果你不能理解数据库，或者不知道什么东西来自哪里，那么你应该find一个人。 即使您可以find数据的位置，也可能在某处重复，或者数据库的其他方面可能不明白。 如果你公司里没有人理解数据库，那你就是一团糟。

如果你真的想要去SQL的方式，你可以尝试使用由Sorna Kumar Muthuraj创build的存储过程 – 复制代码如下。 只需对模式中的所有表执行此存储过程（使用dynamicSQL很容易）

尽pipe之前提出的解决scheme是有效的，但我谦卑地提供了一个更清晰，更优雅，性能更好的代码，至less在我看来是这样。
首先，有人可能会问：为什么有人需要一个代码片段来全局查找一个string？ 嘿，他们已经发明了全文，你不知道吗？
我的回答是：我的工作主要集中在系统集成项目上，每当我正在学习一个新的，未开发的数据库时，发现数据写入的地方是很重要的。
另外，我提供的代码是一个更强大和危险的脚本的精简版本，在整个数据库中search和replace文本。
CREATE TABLE #result( id INT IDENTITY, -- just for register seek order tblName VARCHAR(255), colName VARCHAR(255), qtRows INT ) go DECLARE @toLookFor VARCHAR(255) SET @toLookFor = '[input your search criteria here]' DECLARE cCursor CURSOR LOCAL FAST_FORWARD FOR SELECT '[' + usr.name + '].[' + tbl.name + ']' AS tblName, '[' + col.name + ']' AS colName, LOWER(typ.name) AS typName FROM sysobjects tbl INNER JOIN( syscolumns col INNER JOIN systypes typ ON typ.xtype = col.xtype ) ON col.id = tbl.id -- LEFT OUTER JOIN sysusers usr ON usr.uid = tbl.uid WHERE tbl.xtype = 'U' AND LOWER(typ.name) IN( 'char', 'nchar', 'varchar', 'nvarchar', 'text', 'ntext' ) ORDER BY tbl.name, col.colorder -- DECLARE @tblName VARCHAR(255) DECLARE @colName VARCHAR(255) DECLARE @typName VARCHAR(255) -- DECLARE @sql NVARCHAR(4000) DECLARE @crlf CHAR(2) SET @crlf = CHAR(13) + CHAR(10) OPEN cCursor FETCH cCursor INTO @tblName, @colName, @typName WHILE @@fetch_status = 0 BEGIN IF @typName IN('text', 'ntext') BEGIN SET @sql = '' SET @sql = @sql + 'INSERT INTO #result(tblName, colName, qtRows)' + @crlf SET @sql = @sql + 'SELECT @tblName, @colName, COUNT(*)' + @crlf SET @sql = @sql + 'FROM ' + @tblName + @crlf SET @sql = @sql + 'WHERE PATINDEX(''%'' + @toLookFor + ''%'', ' + @colName + ') > 0' + @crlf END ELSE BEGIN SET @sql = '' SET @sql = @sql + 'INSERT INTO #result(tblName, colName, qtRows)' + @crlf SET @sql = @sql + 'SELECT @tblName, @colName, COUNT(*)' + @crlf SET @sql = @sql + 'FROM ' + @tblName + @crlf SET @sql = @sql + 'WHERE ' + @colName + ' LIKE ''%'' + @toLookFor + ''%''' + @crlf END EXECUTE sp_executesql @sql, N'@tblName varchar(255), @colName varchar(255), @toLookFor varchar(255)', @tblName, @colName, @toLookFor FETCH cCursor INTO @tblName, @colName, @typName END SELECT * FROM #result WHERE qtRows > 0 ORDER BY id GO DROP TABLE #result go
如果您是从应用程序“获取数据”，则明智的做法是在运行应用程序时使用分析器并对数据库进行概要分析。 跟踪它，然后search该string的结果。
适用于Microsoft SQL Server Management Studio和Microsoft SQL Server Management Studio Express的SSMS Tools PACK Add-In（附加组件）将完全满足您的需求。 在较大的数据库上search需要一些时间，但这是可以预料的。 它还包括一大堆很酷的function，首先应该包含在SQL Server Management Studio中。 试试www.ssmstoolspack.com/
您需要安装SQL Server Management Studio的SP2来运行这些工具。
我改编了2002年由Narayana Vyas Kondreddi编写的剧本。 我改变了where子句来检查text / ntext字段，通过使用patindex而不是像。 我也稍微改变了成绩表。 不合理地，我改变了variables名称，并按照我的意愿调整（不对Kondretti先生不敬）。 用户可能想要更改search的数据types。 我使用了一个全局表来允许查询中间处理，但是永久表可能是一个更聪明的方法。

其他答案已经发布可能同样好或更好，但我没有使用它们。 但是，我使用了下面的SQL，当我试图用一个巨大的（而且非常没有组织的）SQL Server数据库来反向工程的时候，它确实帮了我很大的忙。
这不是我的代码。 我希望我可以信任原作者，但我无法find文章的链接了:(
Use go declare @SearchChar varchar(8000) Set @SearchChar = -- Like 'A%', '11/11/2006' declare @CMDMain varchar(8000), @CMDMainCount varchar(8000),@CMDJoin varchar(8000) declare @ColumnName varchar(100),@TableName varchar(100) declare dbTable cursor for SELECT Distinct b.Name as TableName FROM sysobjects b WHERE b.type='u' and b.Name 'dtproperties' order by b.name open dbTable fetch next from dbTable into @TableName WHILE @@FETCH_STATUS = 0 BEGIN declare db cursor for SELECT c.Name as ColumnName FROM sysobjects b, syscolumns c WHERE C.id = b.id and b.type='u' and b.Name = @TableName order by b.name open db fetch next from db into @ColumnName set @CMDMain = 'SELECT ' + char(39) + @TableName + char(39) + ' as TableName,'+ ' ['+ @TableName + '].* FROM [' + @TableName + ']'+ ' WHERE ' set @CMDMainCount = 'SELECT Count(*) FROM [' + @TableName + '] Where ' Set @CMDJoin = '' WHILE @@FETCH_STATUS = 0 BEGIN set @CMDJoin = @CMDJoin + 'Convert(varchar(5000),[' +@ColumnName + ']) like ' + char(39) + @SearchChar + char(39) + ' OR ' fetch next from db into @ColumnName end close db deallocate db Set @CMDMainCount = 'If ('+ @CMDMainCount + Left(@CMDJoin, len(@CMDJoin) - 3)+ ') > 0 Begin ' Set @CMDMain = @CMDMainCount + @CMDMain + Left(@CMDJoin, len(@CMDJoin) - 3) Set @CMDMain = @CMDMain + ' End ' Print @CMDMain exec (@CMDMain) fetch next from dbTable into @TableName end close dbTable deallocate dbTable
其实我同意MikeW（+1）这个案例最好使用profiler。
无论如何，如果你真的需要抓住db中的所有（n）varchar列并进行search。 见下文。 我想使用INFORMATION_SCHEMA.Tables +dynamicSQL。 简单search：
DECLARE @SearchText VARCHAR(100) SET @SearchText = '12' DECLARE @Tables TABLE(N INT, TableName VARCHAR(100), ColumnNamesCSV VARCHAR(2000), SQL VARCHAR(4000)) INSERT INTO @Tables (TableName, ColumnNamesCSV) SELECT T.TABLE_NAME AS TableName, ( SELECT C.Column_Name + ',' FROM INFORMATION_SCHEMA.Columns C WHERE T.TABLE_NAME = C.TABLE_NAME AND C.DATA_TYPE IN ('nvarchar','varchar') FOR XML PATH('') ) FROM INFORMATION_SCHEMA.Tables T DELETE FROM @Tables WHERE ColumnNamesCSV IS NULL INSERT INTO @Tables (N, TableName, ColumnNamesCSV) SELECT ROW_NUMBER() OVER(ORDER BY TableName), TableName, ColumnNamesCSV FROM @Tables DELETE FROM @Tables WHERE N IS NULL UPDATE @Tables SET ColumnNamesCSV = SUBSTRING(ColumnNamesCSV, 0, LEN(ColumnNamesCSV)) UPDATE @Tables SET SQL = 'SELECT * FROM ['+TableName+'] WHERE '''+@SearchText+''' IN ('+ColumnNamesCSV+')' DECLARE @C INT, @I INT, @SQL VARCHAR(4000) SELECT @I = 1, @C = COUNT(1) FROM @Tables WHILE @I <= @C BEGIN SELECT @SQL = SQL FROM @Tables WHERE N = @I SET @I = @I+1 EXEC(@SQL) END
和一个LIKE子句：
DECLARE @SearchText VARCHAR(100) SET @SearchText = '12' DECLARE @Tables TABLE(N INT, TableName VARCHAR(100), ColumnNamesCSVLike VARCHAR(2000), LIKESQL VARCHAR(4000)) INSERT INTO @Tables (TableName, ColumnNamesCSVLike) SELECT T.TABLE_NAME AS TableName, ( SELECT C.Column_Name + ' LIKE ''%'+@SearchText+'%'' OR ' FROM INFORMATION_SCHEMA.Columns C WHERE T.TABLE_NAME = C.TABLE_NAME AND C.DATA_TYPE IN ('nvarchar','varchar') FOR XML PATH('')) FROM INFORMATION_SCHEMA.Tables T DELETE FROM @Tables WHERE ColumnNamesCSVLike IS NULL INSERT INTO @Tables (N, TableName, ColumnNamesCSVLike) SELECT ROW_NUMBER() OVER(ORDER BY TableName), TableName, ColumnNamesCSVLike FROM @Tables DELETE FROM @Tables WHERE N IS NULL UPDATE @Tables SET ColumnNamesCSVLike = SUBSTRING(ColumnNamesCSVLike, 0, LEN(ColumnNamesCSVLike)-2) UPDATE @Tables SET LIKESQL = 'SELECT * FROM ['+TableName+'] WHERE '+ColumnNamesCSVLike DECLARE @C INT, @I INT, @LIKESQL VARCHAR(4000) SELECT @I = 1, @C = COUNT(1) FROM @Tables WHILE @I <= @C BEGIN SELECT @LIKESQL = LIKESQL FROM @Tables WHERE N = @I SET @I = @I +1 EXEC(@LIKESQL) END
@NLwino，很好的查询与关键字使用一些错误。 我不得不稍微修改一下，用[]来包装关键字，还要看char和ntext列。
DECLARE @searchstring NVARCHAR(255) SET @searchstring = '%WDB1014%' DECLARE @sql NVARCHAR(max) SELECT @sql = STUFF(( SELECT ' UNION ALL SELECT ''' + TABLE_NAME + ''' AS tbl, ''' + COLUMN_NAME + ''' AS col, [' + COLUMN_NAME + '] AS val' + ' FROM ' + TABLE_SCHEMA + '.[' + TABLE_NAME + '] WHERE [' + COLUMN_NAME + '] LIKE ''' + @searchstring + '''' FROM INFORMATION_SCHEMA.COLUMNS WHERE DATA_TYPE in ('nvarchar', 'varchar', 'char', 'ntext') FOR XML PATH('') ) ,1, 11, '') Exec (@sql)
我在2.5 GB的数据库上运行它，它在51秒内回来
这不使用游标或类似的东西，只是一个dynamic查询。
另外请注意，这使用LIKE 。 因为那恰好是我所需要的。 它适用于所有模式，所有表和只有查询的那些NVARCHAR或VARCHAR列，即使他们有UDDT。
DECLARE @searchstring NVARCHAR(255) SET @searchstring = '%searchstring%' DECLARE @sql NVARCHAR(max) SELECT @sql = STUFF(( SELECT ' UNION ALL SELECT ''' + TABLE_NAME + ''' AS tablename, ''' + COLUMN_NAME + ''' AS columnname, ' + COLUMN_NAME + ' AS valuename' + ' FROM ' + TABLE_SCHEMA + '.' + TABLE_NAME + ' WHERE ' + COLUMN_NAME + ' LIKE ''' + @searchstring + '''' FROM INFORMATION_SCHEMA.COLUMNS WHERE DATA_TYPE in ('nvarchar', 'varchar') FOR XML PATH('') ) ,1, 11, '') EXEC(@sql)
输出为您提供表，列和值。 在一个小型数据库上执行的时间是〜3秒，有大约3000个结果。

要“find我得到的数据来自哪里”，您可以启动SQL事件探查器，启动您的报告或应用程序，您将看到针对您的数据库发出的所有查询。
我认为这可以是在数据库的所有行中查找string的最简单方法 – 不使用游标和FOR XML 。
CREATE PROCEDURE SPFindAll (@find VARCHAR(max) = '') AS BEGIN SET NOCOUNT ON; -- DECLARE @query VARCHAR(max) = '' SELECT @query = @query + CASE WHEN @query = '' THEN '' ELSE ' UNION ALL ' END + 'SELECT ''' + s.name + ''' As schemaName, ''' + t.name + ''' As tableName, ''' + c.name + ''' As ColumnName, [' + c.name + '] COLLATE DATABASE_DEFAULT As [Data] FROM [' + s.name + '].[' + t.name + '] WHERE [' + c.name + '] Like ''%' + @find + '%''' FROM sys.schemas s INNER JOIN sys.tables t ON s.[schema_id] = t.[schema_id] INNER JOIN sys.columns c ON t.[object_id] = c.[object_id] INNER JOIN sys.types ty ON c.user_type_id = ty.user_type_id WHERE ty.name LIKE '%char' EXEC(@query) END
通过创build这个存储过程，你可以运行任何你想要find的string：
EXEC SPFindAll 'Hello World'
结果将是这样的：
schemaName | tableName | columnName | Data -----------+-----------+------------+----------------------- schema1 | Table1 | Column1 | Hello World schema1 | Table1 | Column1 | Hello World! schema1 | Table2 | Column1 | I say "Hello World". schema1 | Table2 | Column2 | Hello World
或者，你可以在这里使用我的查询，应该更简单，然后必须为每个要search的数据库创buildsProcs： FullParam SQL Blog
