SHOW COLUMNS FROM $table should also work
#!/usr/bin/perl
# connect to db
my $dbh = DBI->connect(bla..bla..bla);
my $sql_q = "SHOW COLUMNS FROM $table";
my $sth = $dbh->prepare($sql_q);
$sth->execute;
while (@row = $sth->fetchrow_array){
print"Field Type Null Key Default Extra\n";
print"----------------------------------------------------\n";
print"$row[0] $row[1] $row[2] $row[3] $row[4] $row[5]\n";
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
