干草堆中的TSQL搜索针

例如，我有一个数据库A，我知道其中一个表中的某个地方是值为C的字段B，但我不知道该字段名或表

---

问：检测（？）哪个表和字段中的值是C的最快方法是什么？

我很久以前写过这个脚本，它对逆向工程非常有用

set nocount off

declare @searchvalue varchar(100)
set @searchvalue = 'text to find'


create table #tt (table_name varchar(64), column_name varchar(64), count int)
select * into #t from 
(
select 'select ''' + a.table_name + ''' ''table_name'',''' + a.column_name + ''' ''column_name'', count(*) count from [' + a.table_name +'] where [' +a.column_name+']='''+@searchvalue +'''' + ' group by ['+ a.column_name+']' sqlstring
from INFORMATION_SCHEMA.COLUMNS a
join 
INFORMATION_SCHEMA.TABLES b
on a.table_name = b.table_name
and b.table_type = 'base table'
 where data_type like '%char'
) a

--loop cursor
Declare @sqlstring as nvarchar(500)
Declare SqlCursor CURSOR FAST_FORWARD FOR
SELECT sqlstring FROM #t
OPEN SqlCursor
FETCH NEXT FROM SqlCursor
INTO @sqlstring
WHILE @@FETCH_STATUS = 0
BEGIN
      -- do row specific stuff here
insert #tt
exec(@sqlstring)
     FETCH NEXT FROM SqlCursor
     INTO @sqlstring
END
CLOSE SqlCursor
DEALLOCATE SqlCursor
select * from #tt
drop table #tt
drop table #t

这可能有用-。随意返工。SSMS tools pack具有此功能。谢谢Martin！我想这是一个很好的选择，但是SSMS工具有什么许可证呢？（GPL？）one@undefined很高兴听到你喜欢我的剧本
