我迷失在一个大数据库中，我无法找到我得到的数据来自哪里。我想知道SQL Server 2005是否可以在数据库的所有表，行和列中搜索字符串？
是否有人知道它是否可能以及如何？
答案 0 :(得分：90)
此代码应该在SQL 2005中执行，但有一些注意事项：
它非常缓慢。我在一个小型数据库上进行了测试，我只有少数几个表，并且需要很长时间才能完成。如果您的数据库太大而无法理解，那么无论如何这都可能无法使用。
我是从袖口上写下来的。我没有进行任何错误处理，可能还有一些其他的邋iness，特别是因为我不经常使用游标。例如，我认为有一种方法可以刷新列光标，而不是每次都关闭/取消分配/重新创建它。
如果你无法理解数据库或者不知道来自哪里，那么你应该找到一个人。即使您可以找到数据的位置，也可能在某处复制，或者您可能还有其他不了解的数据库方面。如果贵公司中没有人理解数据库，那么你就会陷入一团糟。

我建议你发现自己是第三方工具，例如ApexSQL Search（可能还有其他人，但我使用这个，因为它是免费的）。
如果您真的想要采用SQL方式，可以尝试使用创建的存储过程 Sorna Kumar Muthuraj - 复制的代码如下。只需对模式中的所有表执行此存储过程（使用动态SQL很容易）
CREATE PROCEDURE SearchTables
@Tablenames VARCHAR(500)
,@SearchStr NVARCHAR(60)
,@GenerateSQLOnly Bit = 0
AS
/*
Parameters and usage
@Tablenames -- Provide a single table name or multiple table name with comma seperated.
If left blank , it will check for all the tables in the database
@SearchStr -- Provide the search string. Use the '%' to coin the search.
EX : X%--- will give data staring with X
%X--- will give data ending with X
%X%--- will give data containig X
@GenerateSQLOnly -- Provide 1 if you only want to generate the SQL statements without seraching the database.
By default it is 0 and it will search.
Samples :
1. To search data in a table
EXEC SearchTables @Tablenames = 'T1'
,@SearchStr = '%TEST%'
The above sample searches in table T1 with string containing TEST.
2. To search in a multiple table
EXEC SearchTables @Tablenames = 'T2'
,@SearchStr = '%TEST%'
The above sample searches in tables T1 & T2 with string containing TEST.
3. To search in a all table
EXEC SearchTables @Tablenames = '%'
,@SearchStr = '%TEST%'
The above sample searches in all table with string containing TEST.
4. Generate the SQL for the Select statements
EXEC SearchTables @Tablenames = 'T1'
,@SearchStr = '%TEST%'
,@GenerateSQLOnly = 1

虽然之前提出的解决方案是有效且有效的，但我谦卑地提供了一个更干净，更优雅，性能更好的代码，至少在我看来是这样。
首先，有人可能会问：为什么有人需要全局代码片段并盲目寻找字符串？嘿，他们已经发明了全文，你不知道吗？
我的回答：我的主要工作是系统集成项目，每当我学习一个很少发生的新的未填充数据库时，发现数据写入的位置非常重要。
此外，我提供的代码是一个更强大，更危险的脚本的精简版本，可以在整个数据库中搜索和替换文本。

如果您正在从应用程序“获取数据”，那么明智的做法是使用分析器并在运行应用程序时对数据库进行概要分析。跟踪它，然后在结果中搜索该字符串。
答案 4 :(得分：8)
Microsoft SQL Server Management Studio和Microsoft SQL Server Management Studio Express的SSMS工具PACK加载项（加载项）将完全满足您的需求。在较大的数据库上，搜索需要一些时间，但这是可以预期的。它还包括一些很酷的功能，它们应该首先包含在SQL Server Management Studio中。试一试www.ssmstoolspack.com/
您需要安装SP2 for SQL Server Management Studio才能运行这些工具。

我改编了一个最初由Narayana Vyas Kondreddi in 2002编写的脚本。我更改了where子句以检查text / ntext字段，使用patindex而不是like。我也略微改变了结果表。不合理地，我改变了变量名称，并按照我的意愿调整（不尊重Kondretti先生）。用户可能想要更改搜索的数据类型。我使用全局表来查询中间处理，但永久表可能是更明智的方法。

实际上我同意MikeW（+1）最好在这种情况下使用分析器。
无论如何，如果你真的需要在db中获取所有（n）varchar列并进行搜索。见下文。 我想使用INFORMATION_SCHEMA.Tables +动态SQL。 普通搜索：
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)

SELECT @LIKESQL = LIKESQL FROM @Tables WHERE N = @I
SET @I = @I +1

我认为这是在数据库的所有行中查找字符串的最简单方法 - 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
通过创建此存储过程，您可以为要查找的任何字符串运行它，如下所示：
EXEC SPFindAll 'Hello World'
结果如下：
schemaName | tableName | columnName | Data
-----------+-----------+------------+-----------------------
schema1 | Table1 | Column1 | Hello World
schema1 | Table1 | Column1 | Hello World!
schema1 | Table2 | Column1 | I say "Hello World".
