Google has failed me so far. Tried # mysqladmin flush-tables and repeated the steps above but it wasn't helpful. Mysql> ERROR 1005 (HY000): Can't create table 'my_db.my_user' (errno: -1) Mysql> CREATE TABLE my_user (id INT AUTO_INCREMENT NOT NULL, username VARCHAR(255), group_id VARCHAR(255) DEFAULT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE = InnoDB Mysql> ERROR 1051 (42S02): Unknown table 'my_user' ![]() If you want even better assurance of InnoDB being flushed to disk, you should use MySQL in Linux.I'm using these steps to create a table my_user, that already existed but somehow vanished from my database my_db: mysql> USE my_db That way, when you shutdown mysql, InnoDB can more thoroughly flush changes. Once you get this situation squared away, you should tune InnoDB to flush changes to disk. If you have a backup of that lost table (in the form of a mysqldump), you should carry out the steps from my old post and then load the backup of the lost table. I have not used it, but if Percona made it, you should give it a try. Percona can help with our data recovery service. Although the tools are powerful, performing InnoDB data recovery correctly requires expert knowledge of the InnoDB storage format and source code plus experience, and intuition. Percona has used these tools to perform MySQL data recovery for many customers, including extremely large datasets. It can be used for MySQL recovery to retrieve deleted tables, recover previous versions of updated rows, or fix InnoDB file corruption after a hardware failure such as a memory fault or bad cabling. It provides a way to extract InnoDB's data from files or raw devices in a tab-separated format when standard InnoDB recovery cannot be used for some reason such as a dropped table or severe corruption that prevents InnoDB from recognizing the data. The Percona Data Recovery Tool for InnoDB is a free toolkit for recovering lost or corrupted data from InnoDB tables. In the webpage about the Data Recovery Toolkit says However, Percona has the Data Recovery Toolkit for just such an occasion. Based on my old post, I would just mysqldump all the other tables and call you table a lost cause. frm and some tablespace_id is attached to the table name. Yet, you cannot convert it to InnoDB because the metadata somehow imagines that the. It is possible to create the table as MyISAM because it has no attachments to ibdata1 or any other metadata. When you ran SHOW TABLES, all mysqld did was report the. In that post, I basically point out that the metadata of the table is still present inside the system tablespace file ibdata1. ![]() This situation sounds a lot like a post I answered two years ago ( InnoDB table SELECT returns ERROR 2006 (HY000): MySQL server has gone away (after power outage)) Question: Is it possible to recover/repair MY_TABLE, or at least how to drop and create it again (without dropping the database and re-crteating it again)? I need to mention I did not change/move/delete/rename any of mysql files. I tried create table MY_TABLE(.) but I had error as table MY_TABLE already exists, so I tried drop table MY_TABLE but it said Unknown table MY_TABLE! I tried mysqlcheck.exe for repair and check, they failed both, but after that, show tables does not show the table name any longer. show tables on console shows the table name, but desc MY_TABLE and select * from MY_TABLE says unknown table. Today in the morning I got error table MY_TALBE does not exists in the browser. Problem: Last night as usual I stopped working on the project and shutdown the windows normally. XAMPP MySQL is running as windows service. Situation: I have a MySQL database with 104 tables, running locally on XAMPP on windows 7.
