I've not really used Mojo, but I think you probably want something like this...
app->attr(dbh => sub {
my $self = shift;
my $dsn = 'dbi:Oracle:schema';
my $usr = 'Scott';
my $pas = 'tiger';
my $dbh = DBI->connect_cached( $dsn, $usr, $pas );
return $dbh;
});
app->attr(cached_query => sub {
my $self = shift;
my $sql = 'SQL QUERY HERE';
return $self->dbh->prepare_cached( $sql );
});
# later
get '/query' => sub{
my $c = shift;
my $dbh = $c->app->dbh;
my $sth = $c->app->cached_query;
# probably pull @values out from GET query or POST data
my @values = do { ... };
my $results = $dbh->selectall_arrayref($sth, {}, @values);
# and so on
};

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
