在数据库中任意位置查找值

这可能对你有帮助。——来自纳拉亚纳·维亚斯。它搜索给定数据库中所有表的所有列。我以前用过，效果很好。

这是上面链接中的Stored Proc -我所做的唯一更改是将临时表替换为表变量，这样您就不必每次都记得删除它。

END
END
END


SELECT ColumnName, ColumnValue FROM @Results
END

执行存储过程。

 EXEC SearchAllTables 'YourStringHere'

根据bnkdev的回答，我修改了Narayana的代码来搜索所有列，甚至是数字列。

它会运行得慢一些，但这个版本实际上会找到所有匹配项，而不仅仅是文本列中的匹配项。

我对他感激不尽。省了我好几天徒手找!

END
END
END


SELECT ColumnName, ColumnValue FROM #Results

非常感谢这个有用的脚本。

如果你的表有不可转换的字段，你可能需要在代码中添加以下修改:

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

这是我对这个问题的独立看法，我用在我自己的工作中。它可以在SQL2000及更高版本中工作，允许通配符、列过滤，并搜索大多数常规数据类型。

伪代码描述可以是select * from * where any like 'foo'

--------------------------------------------------------------------------------
-- Search all columns in all tables in a database for a string.
-- Does not search: image, sql_variant or user-defined types.
-- Exact search always for money and smallmoney; no wildcards for matching these.
--------------------------------------------------------------------------------
declare @SearchTerm nvarchar(4000) -- Can be max for SQL2005+
declare @ColumnName sysname


--------------------------------------------------------------------------------
-- SET THESE!
--------------------------------------------------------------------------------
set @SearchTerm = N'foo' -- Term to be searched for, wildcards okay
set @ColumnName = N'' -- Use to restrict the search to certain columns, wildcards okay, null or empty string for all cols

我没有把它放在proc形式中，因为我不想在数百个db中维护它，而且它实际上是用于临时工作的。请随意评论错误修复。

这是我解决这个问题的方法。在SQLServer2008R2上测试

INSERT dbo.#Results

SELECT *

END

如果您只需要运行一次这样的搜索，那么您可能可以使用其他答案中已经显示的任何脚本。但除此之外，我建议使用ApexSQL搜索。这是一个免费的SSMS插件，它真的为我节省了很多时间。

在运行任何脚本之前，您都应该根据要搜索的数据类型自定义脚本。如果你知道你正在搜索datetime列，那么就没有必要通过nvarchar列进行搜索。这将加快上面所有查询的速度。

使用JOIN和CURSOR的另一种方法:

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

我之前有一个解决方案，我一直在改进。如果被告知在XML列中搜索，或者如果只提供整数字符串则搜索整数值。

在这里，非常甜蜜和小的解决方案:

as
begin
declare @col_name varchar(500), @tab_name varchar(500);
declare @find_tab TABLE(table_name varchar(100), column_name varchar(100));

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 ' +

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';

你可能需要为你的数据库构建一个反向索引。它肯定是相当快的。

出于开发目的，您可以将所需的表数据导出到单个HTML中，并对其进行直接搜索。

假设你想要获取数据库中所有包含logintime的表，下面的代码示例是MyDatabase

    use MyDatabase


SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%logintime%'
ORDER BY schema_name, table_name;

如果你已经安装了phpMyAdmin，使用它的搜索特性。

选择您的数据库。

请确保您选择的是DataBase，而不是表，否则您将得到一个完全不同的搜索对话框。

1. 单击搜索页签
2. 列表项选择所需的搜索词
3. 选择要搜索的表

我正在寻找一个数值= 6.84 -使用这里的其他答案，我能够将我的搜索限制在这个范围内

Declare @sourceTable Table(id INT NOT NULL IDENTITY PRIMARY KEY, table_name varchar(1000), column_name varchar(1000))
Declare @resultsTable Table(id INT NOT NULL IDENTITY PRIMARY KEY, table_name varchar(1000))


Insert into @sourceTable(table_name, column_name)
select schema_name(t.schema_id) + '.' + t.name as[table], c.name as column_name
from sys.columns c
join sys.tables t
on t.object_id = c.object_id
where type_name(user_type_id) in ('decimal', 'numeric', 'smallmoney', 'money', 'float', 'real')
order by[table], c.column_id;


DECLARE db_cursor CURSOR FOR
Select table_name, column_name from @sourceTable
DECLARE @mytablename VARCHAR(1000);
DECLARE @mycolumnname VARCHAR(1000);


OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO @mytablename, @mycolumnname


WHILE @ @FETCH_STATUS = 0
BEGIN
Insert into @ResultsTable(table_name)
EXEC('SELECT ''' + @mytablename + '.' + @mycolumnname + '''  FROM ' + @mytablename + ' (NOLOCK) ' +
' WHERE ' + @mycolumnname + '=6.84')
FETCH NEXT FROM db_cursor INTO @mytablename, @mycolumnname
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;
Select Distinct(table_name) from @ResultsTable

已经有很多可行的答案了。我只是想分享一个我写的有额外功能的。

到目前为止，我发现的最好和最通用的解决方案是通过管道将db的转储传递给您正在搜索的grep。

例如，Mysql:

mysqldump -pPASSWORD database | grep 'search phrase'

或者如果你得到了太多的结果，你可以把它们输出到一个文件:

mysqldump -pPASSWORD database | grep 'search phrase' > results.txt
