Fellow monasterians,

Using data from a MySQL table, I'm setting up an an AoH for a HTML::Template loop. I start by selecting all the columns because I need a couple 'non-displayable' columns for testing a condition. If the condition is met I want to assign just a few of the key/value pairs of the successful array element to the H::T loop's AoH.

Here's what I have based on something is saw in the Cookbook, pg 105, but is obviously wrong. Can something like this even work?

my $stmt = "SELECT * FROM table WHERE ...
#execute...

my $sqldata = $sth->fetchall_arrayref({});    
my @events;

for my $i ( 0 .. $#$sqldata ) {            
   if ( $sqldata->[$i]{'col5'} eq $sqldata->[$i]{'col8'} ) {
      push ( @events, $sqldata->[$i]{'col1', 'col2', 'col3'} );
   }
}    

my $template = HTML::Template->new( filename => 'some.tmpl' );
$template -> param( events => \@events );
#etc...

or am I resigned to: 

$events[$ctr]{'col1'} = $sqldata->[$i]{'col1');
$events[$ctr]{'col2'} = $sqldata->[$i]{'col2');
$events[$ctr]{'col3'} = $sqldata->[$i]{'col3');
$ctr++;

Thanks all!
