create table photo(id int identity(1,1),photo image,memo nvarchar(50) default 'my photo')
go
insert photo(photo) values(0x)    -- 必须的，且不是null
select * from photo
--truncate table photo

sp_textcopy 'roy','sa','wuxi','test','photo','photo','E:\photo\myphoto\roy3.jpg','where id=5','I' --注意条件是 id=1


3、读入
sp_textcopy 'roy','sa','wuxi','test','photo','photo','E:\photo\photo\21.jpg','where id=1','I' --注意条件是 id=1

sp_textcopy 'roy','sa','wuxi','test','photo','photo','E:\photo\photo\33.jpg','where id=2','I' --注意条件是 id=2

go

4、读出成文件
sp_textcopy 'roy','sa','wuxi','test','photo','photo','E:\photo\roy.jpg','where id=1','O' --注意条件是 id=1
sp_textcopy 'roy','sa','wuxi','test','photo','photo','E:\photo\roy1.jpg','where id=2','O'
sp_textcopy 'roy','sa','wuxi','test','photo','photo','E:\photo\roy2.jpg','where id=3','O'
sp_textcopy 'roy','sa','wuxi','test','photo','photo','E:\photo\roy3.jpg','where id=4','O'

sp_textcopy 'roy','sa','wuxi','test','photo','photo','c:\bb.doc','where id=5','O' --注意条件是 id=2
