嗨，
有人可以解释一下吗？
sqlite> .schema LastFM
CREATE TABLE LastFM(id INTEGER PRIMARY KEY, AlbumTitle TEXT, Hoerer INTEGER);
CREATE INDEX Hoerer_Index ON LastFM( Hoerer DESC );
sqlite> Explain SELECT * FROM LastFM ORDER BY Hoerer;
addr opcode p1 p2 p3 p4 p5

我有一个表 LastFm(id INTEGER PRIMARY KEY, AlbumTitle TEXT, Hoerer INTEGER) 并用来自csv文件的python数据填充它：
reader = csv.reader(open(csvFileName, 'r'), delimiter=';')
对于阅读器中的行：
to_db = []
对于列中的列：
to_db.append(unicode(col, "utf8"))
cur.execute("INSERT INTO LastFM(AlbumTitle, Hoerer) VALUES (?, ?);", to_db)
sqlConnection.commit()
但是“order by”功能无法正常工作。我已经尝试在我想要订购的列上创建一个索引，但它也不起作用。
一些提示？
