给定一个数字，我如何发现在什么表和列中可以找到它?
我不在乎速度快不快，只要管用就行。

如果你安装了phpMyAdmin，使用它的搜索功能。
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。
单击“搜索”页签 列表项选择所需的搜索词 选择要搜索的表
根据bnkdev的回答，我修改了Narayana的代码，以搜索所有列，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!

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。

执行存储过程。
EXEC SearchAllTables 'YourStringHere'
在这里，非常甜蜜和小的解决方案:
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';
我优化了Allain Lalonde的答案(https://stackoverflow.com/a/436676/412368)。 仍然支持数值。应该大约快4-5倍(1:03 vs 4:30)，在带有7GB数据库的桌面上测试。http://developer.azurewebsites.net/2015/01/mssql-searchalltables/
