在MS SQL SERVER 安装目录下有个可执行文件叫 TEXTCOPY.EXE
可对 MS SQL SERVER 中的文本或图像数据进行输入输出.
不过你可以在MS-DOS方式下执行textcopy /? 得到它的描述。
下面是这个工具的描述:
Copies a single text or image value into or out of SQL Server. The val
ue
is a specified text or image 'column' of a single row (specified by th
e
"where clause") of the specified 'table'. 

If the direction is IN (/I) then the data from the specified 'file' is

copied into SQL Server, replacing the existing text or image value. If
the
direction is OUT (/O) then the text or image value is copied from
SQL Server into the specified 'file', replacing any existing file.

TEXTCOPY [/S ][sqlserver]] [/U [login]] [/P ][password]]
  [/D ][database]] [/T table] [/C column] [/W"where clause"]
  [/F file] [{/I | /O}] [/K chunksize] [/Z] [/?]

  /S sqlserver       The SQL Server to connect to. If 'sqlserver' is n
ot
                     specified, the local SQL Server is used.
  /U login           The login to connect with. If 'login' is not spec
ified,
                     a trusted connection will be used.
  /P password        The password for 'login'. If 'password' is not
                     specified, a NULL password will be used.
  /D database        The database that contains the table with the tex
t or
                     image data. If 'database' is not specified, the d
efault
                     database of 'login' is used.
  /T table           The table that contains the text or image value.

  /C column          The text or image column of 'table'.
  /W "where clause"  A complete where clause (including the WHERE keyw
ord)
                     that specifies a single row of 'table'.
  /F file            The file name.
  /I                 Copy text or image value into SQL Server from 'fi
le'.
  /O                 Copy text or image value out of SQL Server into '
file'.
  /K chunksize       Size of the data transfer buffer in bytes. Minimu
m
                     value is 1024 bytes, default value is 4096 bytes.

  /Z                 Display debug information while running.
  /?                 Display this usage information and exit.

You will be prompted for any required options you did not specify.

为此, 可写一个存储过程,调用这个命令
CREATE PROCEDURE sp_textcopy (
  @srvname     varchar (30),
  @login       varchar (30),
  @password    varch
