在数据库内任何表的任何列中搜索一个值

我坐在一个巨大的数据库前，不知道这些表必须如何链接在一起.为了找出答案，我想列出所有表以及在任何行中包含特定值的列.这可能吗?一种方法可能是将整个数据库转储到一个文本文件中，而不是使用任何文本编辑器来搜索值 - 但如果数据库太大，这将是纯粹的痛苦. 解决方案 如何搜索所有的列关键字的数据库中的表?http://vyaskn.tripod.com/search_all_columns_in_all_tables.htm这是实际的 T-SQL，以防链接失效:CREATE PROC SearchAllTables(@SearchStr nvarchar(100))作为开始-- 版权所有 © 2002 Narayana Vyas Kondreddi.版权所有.-- 目的:为给定的搜索字符串搜索所有表的所有列-- 作者:Narayana Vyas Kondreddi-- 网站:http://vyaskn.tripod.com-- 测试:SQL Server 7.0 和 SQL Server 2000-- 修改日期:2002 年 7 月 28 日 22:50 GMTCREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))设置无计数声明 @TableName nvarchar(256)、@ColumnName nvarchar(128)、@SearchStr2 nvarchar(110)SET @TableName = ''SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')虽然@TableName 不为空开始SET @ColumnName = ''设置@表名=(SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))来自 INFORMATION_SCHEMA.TABLESWHERE TABLE_TYPE = '基础表'AND QUOTENAME(TABLE_SCHEMA) + '.'+ QUOTENAME(TABLE_NAME) >@表名和对象属性(对象 ID(QUOTENAME(TABLE_SCHEMA) + '.'+ QUOTENAME(TABLE_NAME)), 'IsMSShipped') = 0)WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)开始设置@列名=(SELECT MIN(QUOTENAME(COLUMN_NAME))来自 INFORMATION_SCHEMA.COLUMNSWHERE TABLE_SCHEMA = PARSENAME(@TableName, 2)AND TABLE_NAME = PARSENAME(@TableName, 1)AND DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar')AND QUOTENAME(COLUMN_NAME) >@列名)如果@ColumnName 不为空开始插入#Results执行('选择''' + @TableName + '.'+ @ColumnName + ''', LEFT(' + @ColumnName + ', 3630)FROM ' + @TableName + ' (NOLOCK) ' +'WHERE' + @ColumnName + 'LIKE' + @SearchStr2)结尾结尾结尾SELECT ColumnName, ColumnValue FROM #Results结尾Is there a way to search for one value (in my case it is a UID of the type char(64)) inside any column of any table inside one MS SQL Server database?I'm sitting in front of a huge database without any idea how the tables had to be linked together. To find that out I'd like to list all tables and there columns that contain a certain value in any row. Is that possible?One way could be to just dump the entire database into a text file and than use any text-editor to search for the value - but this would be pure pain if the database is too huge. 解决方案 How to search all columns of all tables in a database for a keyword?http://vyaskn.tripod.com/search_all_columns_in_all_tables.htmEDIT: Here's the actual T-SQL, in case of link rot: CREATE PROC SearchAllTables(@SearchStr nvarchar(100))ASBEGIN-- Copyright © 2002 Narayana Vyas Kondreddi.
