如何上传，下载sqlserver中blob大字段中的数据-How do I upload, download sqlserver in big blob field data

把文件保存到sql server中(如果是2000，把字段类型设为image),同时读出来。文件大小不限。就是blob操作-Save the file to the sql server (if the 2000, the field type is set to image), also read out. File size limitation.Is the blob operation

这个程序是将c:\1.pdf存储到数据库中，然后通过blob类型的变量将存进数据库中的1.pdf读出来并保存为c:\test.pdf。-This program is c: \ 1.pdf stored in the database, and then through the blob type variable will be deposited into the database 1.pdf read out and saved as c: \ test.pdf.
