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
|
||
|

|
||
|
.sp
|
||
|
.RS 3n
|
||
|
.nf
|
||
|

|

|
