\fBperror [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIerrorcode\fR\fR\fB ...\fR
.SH "DESCRIPTION"
.PP
For most system errors, MySQL displays, in addition to an internal text message, the system error code in one of the following styles:
.sp
.RS 3n
.nf
message ... (errno: #)
message ... (Errcode: #)
.fi
.RE
.PP
You can find out what the error code means by examining the documentation for your system or by using the
\fBperror\fR
utility.
.PP
\fBperror\fR
prints a description for a system error code or for a storage engine (table handler) error code.
.PP
Invoke
\fBperror\fR
like this:
.sp
.RS 3n
.nf
shell> \fBperror [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIerrorcode\fR\fR\fB ...\fR
.fi
.RE
.PP
Example:
.sp
.RS 3n
.nf
shell> \fBperror 13 64\fR
OS error code 13: Permission denied
OS error code 64: Machine is not on the network
.fi
.RE

option:
.sp
.RS 3n
.nf
shell> \fBperror \-\-ndb \fR\fB\fIerrorcode\fR\fR
.fi
