给定一个#,我如何发现可以在哪个表和列中找到它?
我不在乎它是否很快,它只需要工作即可。

这可能对您有帮助。-来自Narayana Vyas。它搜索给定数据库中所有表的所有列。我以前用过它,并且可以正常工作。
这是上述链接中的Stored Proc-我所做的唯一更改是用temp表替换了一个表变量,因此您不必记住每次都将其删除。

如果只需要运行一次这样的搜索,则可以使用其他答案中已经显示的任何脚本。但是否则,我建议为此使用ApexSQL Search。这是一个免费的SSMS插件,确实为我节省了很多时间。
在运行任何脚本之前,应基于要搜索的数据类型对其进行自定义。如果您知道要搜索datetime列,则无需遍历nvarchar列。这将加快上述所有查询的速度。
基于bnkdev的答案,我修改了Narayana的代码以搜索所有列,甚至是数字列。
它的运行速度会变慢,但是此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。
我对此感激不尽。节省了我手工搜索的时间!

这是我对自己工作中使用的这个问题的独立看法。它可以在SQL2000及更高版本中运行,允许通配符,列过滤,并可以搜索大多数常规数据类型。

感谢您的真正有用的脚本。
如果您的表具有不可转换的字段,则可能需要对代码进行以下修改:
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
)

在这里,非常好的解决方案:
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';
使用JOIN和CURSOR的另一种方式:
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
假设如果要获取所有具有名称的表,且其名称包含数据库MyDatabase中的logintime,则下面的代码示例
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;
如果您已安装phpMyAdmin,请使用其搜索功能。
选择您的数据库。
确保您确实选择了数据库,而不是表,否则您将获得完全不同的搜索对话框。
