这篇文章是个上传多个文件到Ms sqlserver的image类型字段的例子，很多办法可以做到，我想介绍的这种方法利用了OSQL.exe和TEXTCOPY.exe工具。
先决条件：
a.必须安装了ms sqlsever 2000的客户端工具
b.sql的用户必须至少是dbowner权限
步骤：
1．建立upload.bat,内容如下：

@ECHO off cls REM ECHO on REM Objective: To upload all the files in the folder to SQL server as a table REM Created by: MAK REM Date: Nov 3, 2004 REM Contact: mak_999@yahoo.com REM Check parameters if "%1"=="" Goto noparmErr if "%1"=="/?" Goto Help REM assign variables set Sourcefolder=%1 set servername=%2 set Databasename=%3 set loginname=%4 set password=%5 set LogFile=%6 Date/t > %6 time /t >> %6 REM Export DIR listing to Dirlist.txt dir %1 /b > Dirlist.txt OSQL /S%2 /U%4 /P%5 /d%3 /Q "if exists (select * from %3.dbo.sysobjects where id = object_id(N'[Myuploadtable]') and OBJECTPROPERTY(id, N'IsUserTable') = 1) drop table %3.dbo.[Myuploadtable] " >> %6 OSQL /S%2 /U%4 /P%5 /d%3 /Q "create table %3.dbo.Myuploadtable (id varchar(500),ImageFiles Image)" >> %6 FOR /F "usebackq delims==" %%i in (Dirlist.txt) do OSQL /S%2 /U%4 /P%5 /Q "insert into %3.dbo.Myuploadtable (id,ImageFiles) values('%%i',' ') " >> %6 FOR /F "usebackq delims==" %%i in (Dirlist.txt) do textcopy.exe /S%2 /U%4 /P%5 /D%3 /Tmyuploadtable /CImagefiles /F"%1%%i" /I /W"where [id]='%%i'" >> %6 GOTo END2 :noparmErr Echo Usage help: example as follows echo ... Echo Objective: To upload all the files in the folder to SQL server Table Echo Created by: MAK Echo USAGE: ECHO .... ECHO .... Echo %0 SourceFolder Servername Databasename Login Password LogFile Goto END2 :Help Echo Usage help: example as follows echo ... Echo Objective: To upload all the files in the folder to SQL server Table Echo Created by: MAK Echo USAGE: ECHO .... ECHO .... Echo %0 SourceFolder Servername Databasename Login Password Logfile Goto END2 :END Echo "Compare Query results Completed" >>%LogFile% date/t >> %LogFile% time/t >> %LogFile% goto END2 :END2

_blank>upload.bat下载

2．把textcopy.Exe从Microsoft SQL Server\MSSQL\Binn目录拷贝到upload.bat同一目录。
3．运行upload.bat,参数如下：

_blank>

Upload - bat文件名
C:\myfiles\ - 所有要传的文件目录（放在一个目录下）
SQL - sqlserver的网络名称或者ip地址
MyDB - 数据库名（必须存在）
sa - 数据库用户名
yeahright - 数据库密码
x.log - 本地log文件
