Virtual Table Cursor Object

struct sqlite3_vtab_cursor {
  sqlite3_vtab *pVtab;      /* Virtual table of this cursor */
  /* Virtual table implementations will typically add additional fields */
};

每个虚拟表模块实现都使用以下结构的子类来描述指向虚拟表并用于循环访问虚拟表的游标。游标是使用模块的xOpen方法创建的，并由xClose方法销毁。游标由模块的xFilter，xNext，xEof，xColumn和xRowid方法使用。每个模块的实现都将定义游标结构的内容以适应自己的需要。

这个超类存在用于定义所有实现共有的游标字段。

 SQLite is in the Public Domain.

Sqlite

SQLite，是一款轻型的数据库，是遵守ACID的关系型数据库管理系统，它包含在一个相对小的C库中。它是D.RichardHipp建立的公有领域项目。它的设计目标是嵌入式的，而且目前已经在很多嵌入式产品中使用了它，它占用资源非常的低，在嵌入式设备中，可能只需要几百K的内存就够了。它能够支持Windows/Linux/Unix等等主流的操作系统，同时能够跟很多程序语言相结合，比如 Tcl、C#、PHP、Java等，还有ODBC接口，同样比起Mysql、PostgreSQL这两款开源的世界著名数据库管理系统来
