I have the following trouble in a mysql server database:

190919 17:35:30 [ERROR] Cannot find or open table abril2017/mexico 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/5.5/en/innodb-troubleshooting.html how you can resolve the problem.

Which is the secure way to resolve this problem?, fortunately is a database backup from the original. I have to run ALTER TABLE table_name DISCARD TABLESPACE or what should I do?

Regards.

  • "Fortunately is a database backup from the original." Perhaps /not/ so fortunate. If you created this database from a "backup" of your original database, then that "backup" does not contain everything in the original database - hence the errors - and, therefore, that backup is useless. I would strongly recommend satisfying yourself that your backup method is actually working (i.e. take a backup, then restore it to another machine and make sure it works!) – Phill W.

  • I didnt explain at all, i mean this database was an extract from the records of the activity from 2017 and this database is damaged, the "original" doesn't have this kind of trouble – Iori_Yagami Sep 20 '19 at 15:23
