.SH "NAME"
perror \- display MySQL error message information
.SH "SYNOPSIS"
.HP \w'\fBperror\ [\fR\fB\fIoptions\fR\fR\fB]\ \fR\fB\fIerrorcode\fR\fR\fB\ \&.\&.\&.\fR\ 'u
\fBperror [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIerrorcode\fR\fR\fB \&.\&.\&.\fR
.SH "DESCRIPTION"
.PP
\fBperror\fR
displays the error message for MySQL or operating system error codes\&. Invoke
\fBperror\fR
like this:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBperror [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIerrorcode\fR\fR\fB \&.\&.\&.\fR
.fi
.if n \{\
.RE
.\}
.PP
\fBperror\fR
attempts to be flexible in understanding its arguments\&. For example, for the
ER_WRONG_VALUE_FOR_VAR
error,
\fBperror\fR
understands any of these arguments:
\fB1231\fR,
001231,
MY\-1231, or
MY\-001231, or
ER_WRONG_VALUE_FOR_VAR\&.
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBperror 1231\fR
MySQL error code MY\-001231 (ER_WRONG_VALUE_FOR_VAR): Variable \*(Aq%\-\&.64s\*(Aq
can\*(Aqt be set to the value of \*(Aq%\-\&.200s\*(Aq
.fi
.if n \{\
.RE
.\}
.PP
If an error number is in the range where MySQL and operating system errors overlap,
\fBperror\fR
displays both error messages:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBperror 1 13\fR
OS error code 1: Operation not permitted
MySQL error code MY\-000001: Can\*(Aqt create/write to file \*(Aq%s\*(Aq (OS errno %d \- %s)
OS error code 13: Permission denied
MySQL error code MY\-000013: Can\*(Aqt get stat of \*(Aq%s\*(Aq (OS errno %d \- %s)
.fi
.if n \{\
.RE
.\}
.PP
To obtain the error message for a MySQL Cluster error code, use the
\fBndb_perror\fR
utility\&.
.PP
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\&.
.PP
\fBperror\fR
supports the following options\&.
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fB\-\-help\fR,
\fB\-\-info\fR,
\fB\-I\fR,
\fB\-?\fR
.sp
Display a help message and exit\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fB\-\-ndb\fR
.sp
Print the error message for a MySQL Cluster error code\&.
.sp
This option was removed in MySQL 8\&.0\&.13\&. Use the
\fBndb_perror\fR
utility instead\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fB\-\-silent\fR,
\fB\-s\fR
.sp

.sp
.RS 4
.ie n \{\

.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fB\-\-verbose\fR,
\fB\-v\fR
.sp
Verbose mode\&. Print error code and message\&. This is the default behavior\&.
