Determine If A Prepared Statement Has Been Reset
int sqlite3_stmt_busy(sqlite3_stmt*);
The sqlite3_stmt_busy(S) interface returns true (non-zero) if the prepared statement S has been stepped at least once using sqlite3_step(S) but has neither run to completion (returned SQLITE_DONE from sqlite3_step(S)) nor been reset using sqlite3_reset(S). The sqlite3_stmt_busy(S) interface returns false if S is a NULL pointer. If S is not a NULL pointer and is not a pointer to a valid prepared statement object, then the behavior is undefined and probably undesirable.
This interface can be used in combination sqlite3_next_stmt() to locate all prepared statements associated with a database connection that are in need of being reset. This can be used, for example, in diagnostic routines to search for prepared statements that are holding a transaction open.

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
