基于VFP9语言编程的超大文件存入MS-SQL的实现研究

Research on the implementation of large file storage MS-SQL based on VFP9 language programming

计算机文件是指以计算机硬盘为载体存储在计算机上的信息集合,包括:文本文档、压缩文档、图片、视频、程序等。文章通过对文件存储到数据库的研究,对大小不同尺寸的各类文件进行存储时,发现超大尺寸文件存储到数据库会出现切断问题。文章基于VFP9语言的编程采用分块技术,实现将超大文件存入SQL数据库中,完成各种文件的存储和还原。

A computer file is a collection of information stored on a computer with a computer hard disk as the carrier,include the text documents,compressed documents,pictures,videos,programs,etc.Through the research of file storage to database,it is found that the problem of cut-off occurs when the large-size files are stored to the database when they are stored in different sizes.Then,by using block technology based on VFP9 language programming,the super-sized files are stored in the SQL database to complete the storage and restoration of various files in this paper.
