4.8.1 perror — Explain 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 ...


shell> perror 13 64
OS error code  13:  Permission denied
OS 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

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.

Regarding list of MySQL errors.

If you use unix, you can generate the list with the command:
perror `seq a b`
where a is the first error code and b is the last error code you want to list.
For example,
perror `seq 0 10`
shows codes 0 through 10.

In Windows you will find perror in 'mysql\bin'

from the command line in this directory run the program with your error code;

perror.exe 2

This will return the results;
Error Code 2: No such file or directory

To generate an error list if you don't have the seq command on your system, and you do have perl:

perror `perl -e "print join ' ',1..100"`

Where 1 is the first error number, and 100 is the last error number you want to see (similar to seq).

The error return codes are listed here:
Although the messages aren't listed (yet?). See also the following bug report (and don't hesitate to vote!):
