MySQL errno 의미 확인

perror, Explaining 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 either 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

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.
