**应用程序必须在关闭sqlite3对象前，[sqlite3_finalize | finalize]

**所有的与该对象相关的[prepared statements]，必须[sqlite3_blob_close | **close]所有的与该对象相关的

**[BLOB handles] (BLOB大二进制句柄)

** Applications must [sqlite3_**finalize | finalize] all [prepared statements]

** and [sqlite3_blob_close | close] all [BLOB handles] associated with

** the [sqlite3] object prior to attempting to close the object.  ^If

** sqlite3_close() is called on a [database connection] that still has

** outstanding [prepared statements] or [BLOB handles], then it returns

** SQLITE_BUSY.

**如果sqlite3_close()在[database connection]数据库连接被调用，该数

**据库连接中仍有显式的[prepared statements][BLOB handles]，则返回

**SQLITE_BUSY。当事务打开时，调用sqlite3_close()，事务自动回滚。

** ^If [sqlite3_close()] is invoked while a transaction is open,

** the transaction is automatically rolled back.

**sqlite3_close(C)的C参数可以是NULL指针或从sqlite3_open()、sqlite3_**open16()、sqlite3_open_v2()获取的[sqlite3]对象指针

**使用NULL参数调用sqlite3_close()为没负作用的空操作

** The C parameter to [sqlite3_close(C)] must be either a NULL

** pointer or an [sqlite3] object pointer obtained

** from [sqlite3_open()], [sqlite3_open16()], or

** [sqlite3_open_v2()], and not previously closed.

** ^Calling sqlite3_close() with a NULL pointer argument is a 

** harmless no-op.
