.SH "DESCRIPTION"
.PP
The
\fBmysqlshow\fR
client can be used to quickly see which databases exist, their tables, or a table\*(Aqs columns or indexes\&.
.PP
\fBmysqlshow\fR
provides a command\-line interface to several SQL
SHOW
statements\&. See
Section\ \&13.7.7, \(lqSHOW Statements\(rq\&. The same information can be obtained by using those statements directly\&. For example, you can issue them from the
\fBmysql\fR
client program\&.
.PP
Invoke
\fBmysqlshow\fR
like this:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlshow [\fIoptions\fR] [\fIdb_name\fR [\fItbl_name\fR [\fIcol_name\fR]]]

.RS 4
.ie n \{\

.\}

.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1

.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
If no column is given, all matching columns and column types in the table are shown\&.
.RE
.PP
The output displays only the names of those databases, tables, or columns for which you have some privileges\&.
.PP
If the last argument contains shell or SQL wildcard characters (*,
?,
%, or
_), only those names that are matched by the wildcard are shown\&. If a database name contains any underscores, those should be escaped with a backslash (some Unix shells require two) to get a list of the proper tables or columns\&.
*
and
?
characters are converted into SQL
%
and
_
wildcard characters\&. This might cause some confusion when you try to display the columns for a table with a
_
in the name, because in this case,
\fBmysqlshow\fR
shows you only the table names that match the pattern\&. This is easily fixed by adding an extra
%
last on the command line as a separate argument\&.
.PP
\fBmysqlshow\fR
supports the following options, which can be specified on the command line or in the
[mysqlshow]
and
[client]
groups of an option file\&. For information about option files used by MySQL programs, see
