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]]
