Find a string by searching all tables in SQL Server Management Studio 2008
提问by Ramiz Raja
Is there any way to search for a string in all tables of a database in SQL Server Management Studio 2008?
有没有什么办法可以在SQL Server Management Studio 2008中的数据库的所有表中搜索字符串？
I want to search for string say john. The result should show the tables and their respective row that contain john.
我想搜索字符串 say john。结果应显示包含john.

If you are like me and have certain restrictions in a production environment, you may wish to use a table variable instead of temp table, and an ad-hoc query rather than a create procedure.
如果你和我一样，在生产环境中有一定的限制，你可能希望使用表变量而不是临时表，以及临时查询而不是创建过程。
Of course depending on your sql server instance, it must support table variables.
当然取决于你的sql server实例，它必须支持表变量。
I also added a USE statement to narrow the search scope
我还添加了一个 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(
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', 'int', 'decimal')
AND QUOTENAME(COLUMN_NAME) > @ColumnName
)
IF @ColumnName IS NOT NULL
BEGIN
INSERT INTO @Results
EXEC
(
'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630)

END

Why not try some of the third party tools that can be integrated into SSMS.
为什么不尝试一些可以集成到 SSMS 中的第三方工具。
I've worked with ApexSQL Search(100% free) with good success for both schema and data search and there is also SSMS tools packthat has this feature (not free for SQL 2012 but quite affordable).
我曾使用ApexSQL Search（100% 免费）在模式和数据搜索方面取得了良好的成功，还有具有此功能的SSMS 工具包（SQL 2012 不是免费的，但非常实惠）。
Stored procedure above is really great; it's just that this is way more convenient in my opinion. Also, it would require some slight modifications if you want to search for datetime columns or GUID columns and such…
上面的存储过程真的很棒；只是在我看来这更方便。此外，如果您要搜索日期时间列或 GUID 列等，则需要稍作修改……

To update TechDo's answer for SQL server 2012. You need to change: 'FROM ' + @TableName + ' (NOLOCK) 'toFROM ' + @TableName + 'WITH (NOLOCK) ' +
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) ' +
Other wise you will get the following error: Deprecated feature 'Table hint without WITH' is not supported in this version of SQL Server.
否则，您将收到以下错误： Deprecated feature 'Table hint without WITH' is not supported in this version of SQL Server.
Below is the complete updated stored procedure:

I have written a SP for the this which returns the search results in form of Table name, the Column names in which the search keyword string was found as well as the searches the corresponding rows as shown in below screen shot.
我为此编写了一个 SP，它以表名的形式返回搜索结果，在其中找到搜索关键字字符串的列名以及搜索相应的行，如下面的屏幕截图所示。
This might not be the most efficient solution but you can always modify and use it according to your need.
这可能不是最有效的解决方案，但您可以随时根据需要修改和使用它。

This was very helpful. I wanted to import this function to a Postgre SQL database. Thought i would share it with anyone who is interested. Will have them a few hours. Note: this function creates a list of SQL statements that can be copied and executed on the Postgre database. Maybe someone smarter then me can get Postgre to create and execute the statements all in one function.
这非常有帮助。我想将此函数导入 Postgre SQL 数据库。以为我会与任何感兴趣的人分享。将有他们几个小时。注意：这个函数创建了一个可以在 Postgre 数据库上复制和执行的 SQL 语句列表。也许比我更聪明的人可以让 Postgre 在一个函数中创建和执行所有语句。

The answer that was mentioned in this post already several times I have adopted a little bit because I needed to search in only one table too:
这篇文章中提到的答案已经多次采用了，因为我也只需要在一张表中进行搜索：
(and also made input for the table name a bit more simpler)
（并且还使表名的输入更简单一些）

DECLARE @ColumnName nvarchar(128) = '', @SearchStr2 nvarchar(110)

There's no need for nested looping (outer looping through tables and inner looping through all table columns). One can retrieve all (or arbitrary selected/filtered) table-column combinations from INFORMATION_SCHEMA.COLUMNSand in one loop simply pass through (search) all of them:
不需要嵌套循环（通过表的外循环和通过所有表列的内循环）。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，只需通过（搜索）所有这些组合：
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
DEALLOCATE curTabCol
