我正在尝试使用Python (传统型，2.7)和SQLite (3)编写一个 book indexer 。

代码可以归结为以下SQL语句序列：

'select count(*) from tag_dict' ()
/* [(30,)] */
'select count(*) from file_meta' ()
/* [(63613,)] */
'begin transaction' ()
'select id from archive where name=?' ('158326-158457.zip',)
/* [(20,)] */
'select id from file where name=? and archive=?' ('158328.fb2', 20)
