NAME

       perror - display MySQL error message information

SYNOPSIS

       perror [options] errorcode ...

DESCRIPTION

       perror displays the error message for MySQL or operating system error codes. Invoke perror
       like this:

           perror [options] errorcode ...

       perror attempts to be flexible in understanding its arguments. For example, for the
       ER_WRONG_VALUE_FOR_VAR error, perror understands any of these arguments: 1231, 001231,
       MY-1231, or MY-001231, or ER_WRONG_VALUE_FOR_VAR.

           $> perror 1231
           MySQL error code MY-001231 (ER_WRONG_VALUE_FOR_VAR): Variable '%-.64s'
           can't be set to the value of '%-.200s'

       If an error number is in the range where MySQL and operating system errors overlap, perror
       displays both error messages:

           $> perror 1 13
           OS error code   1:  Operation not permitted
           MySQL error code MY-000001: Can't create/write to file '%s' (OS errno %d - %s)
           OS error code  13:  Permission denied
           MySQL error code MY-000013: Can't get stat of '%s' (OS errno %d - %s)

       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 a MySQL Cluster error code.

           This option was removed in MySQL 8.0.13. 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.
