也谈VisuaI C++实现数据库大字段存取

STORING AND LOADING OF BIG FIELD IN DATABASE USING VISUAL C++

本文讨论了在Visual C++中使用ODBC API函数,如何把图像文件和文档文件等二进制数据存储到SQLServer中数据表的image类型字段中,以及如何从SQLServer中数据表的image类型字段中读取存储的图像文件和文档文件等二进制数据。

This paper deals with the storing and loading of big field, using ODBC API functions in Visual C ++ . How to store binary data, such as image file and document file,into field of image type in data table of SQLServer,and how to load binary data,such as image file and document file, from field of image type in data table of SQLServer are discussed.
