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 an NDB Cluster error code,
invoke perror with the
--ndb
option:
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.
