摘要
在数据库中的长二进制类型字段往往存储了如声音文件,"大文本文件"等大对象数据,并且这些数据以二进制流的形式存储,如何来存取这些数据就成了要解决的问题。文章以"大文本文件"为例,讨论了在VC++6.0中,如何利用ADO中对ACCESS数据库中的OLE对象类型的数据进行读取和存储。
Large object data(sound file and large text file etc.) can be stored in binary type fields of database in form of long binary stream,how to access these data has become our problem to be solved.Based on large text file as an example,this paper discussed how to use ADO techinology to access the OLE object data of ACCESS database in VC++6.0.
