7.15. perrorExplain Error Codes

For most system errors, MySQL displays, in addition to an internal text message, the system error code in one of the following styles:

message ... (errno: #) message ... (Errcode: #)

You can find out what the error code means by examining the documentation for your system or by using the perror utility.

perror prints a description for a system error code or for a storage engine (table handler) error code.

Invoke perror like this:

shell> perror [options] errorcode...

Example: shell> perror 13 64 Error code 13: Permission denied Error code 64: Machine is not on the network

To obtain the error message for a MySQL Cluster error code, invoke perror with the --ndb option:

shell> perror --ndb errorcode

Note that the meaning of system error messages may be dependent on your operating system. A given error code may mean different things on different operating systems.

perror supports the following options:

• --help, --info, -I, -?

  Display a help message and exit.

• --ndb

  Print the error message for a MySQL Cluster error code.

• --silent, -s

  Silent mode. Print only the error message.

• --verbose, -v

  Verbose mode. Print error code and message. This is the default behavior.

• --version, -V

  Display version information and exit.
