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;
}
# later
get '/query' => sub{
my $c = shift;
my $dbh = $c->app->dbh;
my $sql = 'SQL QUERY HERE';
my $sth = $dbh->pepare_cached( $sql );
my $details = $dbh->selectall_arrayref( $sql, { Slice = {} });
# and so on
};
IN above example, I do prepare cached, but don't know how to call the cached query each time the route is visitied. 1. is my initial DBH setup optimal? 2. How do I make use of prepare_cached? Thanks

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).
