下面是一个拷贝图像到SQL Server的pubs数据库的例子, 表名pub_info, 字段名logo,图像文件名picture.bmp,保存到pub_id='0736'记录
sp_textcopy @srvn
ame = 'ServerName',
@login = 'Login',
@password = 'Password',
@dbname = 'pubs',
@tbname = 'pub_info',
@colname = 'logo',
@filename = 'c:\picture.bmp',
@whereclause = " WHERE pub_id='0736' ",
@direction = 'I'
sp_textcopy @srvn
ame = 'ServerName',
@login = 'Login',
@password = 'Password',
@dbname = 'pubs',
@tbname = 'pub_info',
@colname = 'logo',
@filename = 'c:\picture.bmp',
@whereclause = " WHERE pub_id='0736' ",
@direction = 'I'

rs.Close

Exit Sub

End Sub
Private Sub LoadPictureFromDB(cn As ADODB.Connection)
On Error GoTo EH
