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.
