NAME
perror - display MySQL error message information
SYNOPSIS
perror [options] errorcode ...
DESCRIPTION
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:
perror [options] errorcode ...
Examples:
$> perror 1231
MySQL error code 1231 (ER_WRONG_VALUE_FOR_VAR): Variable '%-.64s' can't
be set to the value of '%-.200s'
$> 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, use the ndb_perror utility.
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 an NDB Cluster error code.
This option is deprecated in NDB 7.6.4 and later, where perror prints a warning if it is used, and is
removed in NDB Cluster 8.0. Use the ndb_perror utility instead.
• --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.
