8.16. 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 ...
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.
