如何将映像从SQL Server导出到磁盘上的文件？ [英] How can I export images from SQL Server to a file on disk?

问题描述

我有一个用户表，其所有的头像都保存在图像字段中。我想把它从数据库中拿出来，并将其作为一个常规的文件存储在磁盘上。

I have a User table that has all of their avatars saved in an image field. I'd like to just take that out of the database and store it as a regular file on disk.

我环顾四周，看到一些代码为textcopy，但是由于某种原因似乎在我的机器上这是我写的代码。任何人都知道这样做的方法？

I looked around and saw some code for textcopy, but that doesn't seem to be on my machine for some reason. Here is the code I wrote up anyway. Anyone know a way to get this done?

DECLARE @exec_str varchar (255)
SELECT @exec_str =
         'textcopy /S (local)\SQLEXPRESS' +
         --' /U ' + @login +
         --' /P ' + @password +
         ' /D thedatabase' +
         ' /T User'+
         ' /C AvatarImage' +
         ' /F "d:\Avatars\' + User.Name + '.jpg"' +
         ' /O'
FROM [User]
WHERE UserID = 2
EXEC master..xp_cmdshell @exec_str
