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!

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/

您可能需要为数据库构建一个倒立索引。它肯定是相当快的。

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。

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。
