如何在SQL Server数据库中的任何地方find值？
给定一个＃，我如何发现在哪个表和列中可以find？
我不在乎速度如何，只需要工作。
这可能会帮助你 。 – 来自Narayana Vyas。 它search给定数据库中所有表的所有列。 我以前用过它，它工作。
这是从上面的链接的存储过程 – 我做的唯一的变化是用临时表代替表variables，所以你不必记得每次都删除它。

它会运行得更慢，但是这个版本实际上find所有匹配，不只是在文本列中find的匹配。
我无法感谢这个人。 保存了我手工search的日子！

如果你只需要运行一次这样的search，那么你可以使用这里已经显示的任何脚本。 但除此之外，我build议使用ApexSQLsearch 。 这是一个免费的SSMS插件，它真的为我节省了很多时间。
在运行上面的任何脚本之前，您应该根据您想要的数据types对其进行自定义。 如果您知道您正在searchdatetime列，那么不需要通过nvarchar列进行search。 这将加快上面的所有查询。
这是我独立承担这个我用于自己工作的问题。 它工作在SQL2000及更高版本，允许通配符，列过滤，并将search大部分正常的数据types。

我不把它放在proc的forms，因为我不想把它保持在数百个数据库中，而且它确实是为了特别的工作。 请随时评论bug修复。
我优化了Allain Lalonde的答案（ https://stackoverflow.com/a/436676/412368 ）。 数值仍然受支持。 应该是大约4-5倍（1:03比4:30），在7GB数据库的桌面上testing。 http://developer.azurewebsites.net/2015/01/mssql-searchalltables/

感谢真正有用的脚本。
如果您的表具有不可转换的字段，则可能需要将以下修改添加到代码中：
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 NOT IN ('text', 'image', 'ntext') AND QUOTENAME(COLUMN_NAME) > @ColumnName )
克里斯
您可能必须编写一个简短的脚本来从数据库中查询元数据（在这种情况下是表/列的列表），然后发出一系列查找值的select语句。
这是我解决这个问题的方法。 在SQLServer2008R2上testing
CREATE PROC SearchAllTables @SearchStr nvarchar(100) AS BEGIN DECLARE @dml nvarchar(max) = N'' IF OBJECT_ID('tempdb.dbo.#Results') IS NOT NULL DROP TABLE dbo.#Results CREATE TABLE dbo.#Results ([tablename] nvarchar(100), [ColumnName] nvarchar(100), [Value] nvarchar(max)) SELECT @dml += ' SELECT ''' + s.name + '.' + t.name + ''' AS [tablename], ''' + c.name + ''' AS [ColumnName], CAST(' + QUOTENAME(c.name) + ' AS nvarchar(max)) AS [Value] FROM ' + QUOTENAME(s.name) + '.' + QUOTENAME(t.name) + ' (NOLOCK) WHERE CAST(' + QUOTENAME(c.name) + ' AS nvarchar(max)) LIKE ' + '''%' + @SearchStr + '%''' FROM sys.schemas s JOIN sys.tables t ON s.schema_id = t.schema_id JOIN sys.columns c ON t.object_id = c.object_id JOIN sys.types ty ON c.system_type_id = ty.system_type_id AND c .user_type_id = ty .user_type_id WHERE t.is_ms_shipped = 0 AND ty.name NOT IN ('timestamp', 'image', 'sql_variant') INSERT dbo.#Results EXEC sp_executesql @dml SELECT * FROM dbo.#Results END
我刚才有一个解决scheme，我一直在改进。 如果被告知这么做，也在XML列中进行search，或者在提供整数string的情况下search整数值。

使用JOIN和CURSOR的另一种方法是：
USE My_Database; -- Store results in a local temp table so that. I'm using a -- local temp table so that I can access it in SP_EXECUTESQL. create table #tmp ( tbl nvarchar(max), col nvarchar(max), val nvarchar(max) ); declare @tbl nvarchar(max); declare @col nvarchar(max); declare @q nvarchar(max); declare @search nvarchar(max) = 'my search key'; -- Create a cursor on all columns in the database declare c cursor for SELECT tbls.TABLE_NAME, cols.COLUMN_NAME FROM INFORMATION_SCHEMA.TABLES AS tbls JOIN INFORMATION_SCHEMA.COLUMNS AS cols ON tbls.TABLE_NAME = cols.TABLE_NAME -- For each table and column pair, see if the search value exists. open c fetch next from c into @tbl, @col while @@FETCH_STATUS = 0 begin -- Look for the search key in current table column and if found add it to the results. SET @q = 'INSERT INTO #tmp SELECT ''' + @tbl + ''', ''' + @col + ''', ' + @col + ' FROM ' + @tbl + ' WHERE ' + @col + ' LIKE ''%' + @search + '%''' EXEC SP_EXECUTESQL @q fetch next from c into @tbl, @col end close c deallocate c -- Get results select * from #tmp -- Remove local temp table. drop table #tmp
在这里，非常甜蜜的小解决scheme：
1) create a store procedure: create procedure get_table @find_str varchar(50) as begin declare @col_name varchar(500), @tab_name varchar(500); declare @find_tab TABLE(table_name varchar(100), column_name varchar(100)); DECLARE tab_col cursor for select C.name as 'col_name', T.name as tab_name from sys.tables as T left outer join sys.columns as C on C.object_id=T.object_id left outer join sys.types as TP on C.system_type_id=TP.system_type_id where type='U' and TP.name in('text','ntext','varchar','char','nvarchar','nchar'); open tab_col fetch next from tab_col into @col_name, @tab_name while @@FETCH_STATUS = 0 begin insert into @find_tab exec('select ''' + @tab_name + ''',''' + @col_name + ''' from ' + @tab_name + ' where ' + @col_name + '=''' + @find_str + ''' group by ' + @col_name + ' having count(*)>0'); fetch next from tab_col into @col_name, @tab_name; end CLOSE tab_col; DEALLOCATE tab_col; select table_name, column_name from @find_tab; end
==========================
2) call procedure by calling store procedure: exec get_table 'serach_string';
ALTER PROC [dbo].[pSearchAllTables] ( @SearchStr nvarchar(100) ) AS BEGIN 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(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') 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 END
我曾经为自己写过一个工具来完成这件事：
a7 SqlTools
它是免费的，开源的：

您可能需要为您的数据库build立一个倒排索引 。 这是相当快的。
