NAME¶perror - display MySQL error message information
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:
shell> perror [options] errorcode ...
shell> perror 1231 MySQL error code 1231 (ER_WRONG_VALUE_FOR_VAR): Variable '%-.64s' can't be set to the value of '%-.200s'
shell> 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.
Display a help message and exit.
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 mode. Print only the error message.
Verbose mode. Print error code and message. This is the default behavior.
Display version information and exit.
