描述:
Cannot find or open table phpwind/pw_zhuanti from the internal data dictionary of InnoDB though the .frm file for the table exists. Maybe you have deleted and recreated InnoDB data files but have forgotten to delete the corresponding .frm files of InnoDB tables, or you have moved .frm files to another database? or, the table contains indexes that this version of the engine
doesn't support.
See http://dev.mysql.com/doc/refman/5.1/en/innodb-troubleshooting.html
how you can resolve the problem.

但是查了一下，并没有这个表啊。这个的错误的意思大概是某表已经删除了，但是.frm文件还存在，所以会造成读取错误等等。

于是服务器上找了一下，在mysql数据存储文件夹，找到了pw_zhuanti.frm文件，删除，之后解决了，再也没有出现过这个问题了。
