SQLServer批量倒入目录文件 收藏
可以用扩展存储过程xp_dirtree获取文件列表，用openrowset倒入数据到二进制字段。
openrowset的用法可以参考msdn
http://technet.microsoft.com/zh-cn/library/ms190312.aspx
如果文件很多，建议还是用程序倒入了
if (object_id ('t_bulkResult' ) is not null )
drop table t_bulkResult
create table t_bulkResult (name varchar (1000 ), data image )
go
declare @d varchar (1000 )
set @d = 'c:\test\'
create table #tb (fName varchar (1000 ), d int , f int )
insert into #tb exec xp_dirtree @d , 1 , 1
delete from #tb where f <> 1
declare @ sql nvarchar (max )
select @ sql = isnull (@ sql , '' )+ 'insert into t_bulkResult select ''' +@d + fname + ''',* from openrowset(bulk N''' +@d + fName + ''', SINGLE_BLOB) b
'
from #tb a
exec sp_executesql @ sql
drop table #tb
select * from t_bulkResult

sqlserver2005有关键字ntile(x)和over(partition by.. order by..)子句配合.
比如获取每个表的前10%个字段。
select id , name , colid , rn from (
select * , rn = ntile (10 )
over (partition by id order by colorder )
from syscolumns )t where rn = 1 ......
