I've got a poorly-implemented database that I'm saddled with for at least another 4-N months. I would like to remove the SQL from within the Perl script to "some other place". Except, part of the SQL is dynamically generated. Right now, it looks something like: 
my $dyn_sql_maker = Some::Class->new(
    type => $cgi->param('type'),
    id   => $cgi->param('id'),
    # etc ...
);

my $sql = '';
$sql .= $dyn_sql_maker->select_clause . "
    Report-specific static SQL here
";

$sql .= $dyn_sql_maker->from_clause . "
    Report-specific static SQL here
";

$sql .= $dyn_sql_maker->where_clause . "
    Report-specific static SQL here
";

$sql .= $dyn_sql_maker->groupby_clause . "
    Report-specific static SQL here
";

# Do something with the SQL

The static stuff is based solely on which report you're running and not your type nor your id. The dynamic stuff is based solely on your type and id, but not which report you're running. And, these are 5-8 table joins with craziness heavily involved, so I can't use Class::DBI (Which is actually figuring into my resdesign of the schema ... I'm designing it to be able to use Class::DBI.)

Is there a module out there that will fit my needs? I'd rather not write one, if I didn't have to.
