The code is as follows: Cannot find or open table phpwind/pw_zhuanti from the internal data dictionary of InnoDB though. 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?

Doesn' t support.

How you can resolve the problem.

But I checked it. This table does not exist. This error indicates that a table has been deleted, but the. frm file still exists, causing read errors.

So I looked for it on the server and found the pw_zhuanti.frm file in the mysql data storage folder, deleted it, and solved it. This problem has never occurred again.
