MySQL Database Errors


MySQL is an open source relational database management system which is the product of Sun Microsystems and now it is functioning under Oracle Corporation. This product is used widely for managing records in the databases and tables.

But at times users encounter MySQL errors while accessing or updating records in the MySQL database. These error messages make the database un-mountable and ultimately inaccessible.

In MySQL database generally two types of error messages are thrown i.e. server errors and client errors. Server errors in MySQL are thrown due to the issues caused in the server and it is totally internal, client is nothing to do with this errors.

MySQL server errors are generally thrown when any internal server related issues occur like database corruption, storage engines like MyISAM or InnoDB corruption and so on. Some of the common server related MySQL errors are as follows –

  • Error: 1008 SQLSTATE: HY000 (ER_DB_DROP_EXISTS)
    Message: Can't drop database '%s'; database doesn't exist.
  • Error: 1007 SQLSTATE: HY000 (ER_DB_CREATE_EXISTS)
    Message: Can't create database '%s'; database exists.
  • Error: 1010 SQLSTATE: HY000 (ER_DB_DROP_RMDIR)
    Message: Error dropping database (can't rmdir '%s', errno: %d).

In MySQL, client errors are thrown due to installation related issues, administration related issues, database optimizer related issues, query-related issues, table definition-related issues and some unknown issues. Some of the client related MySQL error messages are as follows –

  • Access denied.
  • Out of memory.
  • The table is full.
  • Can't create/write to file.
  • Commands out of sync.
  • Table ‘tbl_name’ doesn't exist.
  • ‘File’ Not Found and Similar Errors etc.

These types of MySQL database errors and issues can be rectified by using some of the inbuilt utilities like –

  • CHECK TABLE tablename [option].
  • REPAIR TABLE tablename [option].
  • mysqlcheck or myisamchk etc.

But these inbuilt utilities are not always effective and at times it fails to rectify the MySQL server and client issues At that point of time to resolve the MySQL database corruption and its errors any third party software need to be used. Try MySQL Repair software for that purpose which effectively scans the MySQL database and repairs the bugs and makes the database accessible for the users. So, if you are also facing any kind of MySQL errors which is not rectified by the inbuilt tools then use the above mentioned software make your database up to date.
