SQLITE数据库存储类对象 用到qt的QByteArray

typedef struct student_{ int sno; string sname;}student;     //学生的结构vector<student> data_vectordata_vector.push_back(student);QByteArray binary_data;binary_data.resize(sizeof(student)*data_vector.size());memcpy(binary_data.data(),(char*)&data_vector[0],sizeof(student)*data_vector.size());//类对象数据的还原student* data = (student*)binary_data.data();
