SQLite移动嵌入式数据库BLOB类型的应用

摘要

在对移动嵌入式数据库中BLOB数据类型分析的基础上，使用C语言的API函数调用移动SQLite数据库语句，并按其访问模式调用连接函数，实现了SQLite移动数据库中二进制大对象和C结构体类型数组的BLOB处理方法。随着图像和音视频数据的日益增多，BLOB数据类型在SQLite中的应用将更为广阔，给出的Demo实例验证了这一技术的有效性。%Based on the analysis of BLOB data type in mobile embedded database, the API function of C language calls mobile SQLite database statements and connection function is called according to its access mode, which achieves BLOB method of binary large objects and C structure array in SQLite mobile database. With the increase of images as well as audio and video data, the application of BLOB data type in SQLite will be broader. Demo examples are given to verify the effectiveness of this technology.
