I believe this will work:
<code>
#EARLIER
$self->param( 'sql' => \%sql );
#LATER
$self->param( 'sql' )->{page_id} = 45;
</code>
Where the concept is that the value of the 'sql' param is a hash reference, so you just need to retrieve that and work with it as if it you had done something like <c>my $href= \%sql;</c><br>
In the line above, it simply deferences the return value of <c>$self->param( 'sql' )</c> and sets the page_id key to 45.
