If the ids are in another table (eg table_id) then you could use a join (inner) to filter the results. Here's an example using SQL::Abstract::More
#!perl
use strict;
use DBIx::Simple;
use SQL::Abstract::More;
my $dbh = '....'; # connect
$dbh->abstract = SQL::Abstract::More->new();
my @ww = qw/a b c/;
my @data = $dbh->select(
-from => [ -join => qw/table id=id table_id/],
-columns => ['part'],
-where => {
ww => {-in => [@ww] },
part => {-not_like => '0000000%'} },
-union => [
-columns => ['n'],
-where => {
ww => {-in => [@ww] },
part => {-like => '0000000%'} }
],
-group_by => ['part'],
)->flat;
print 'The uin count is '.scalar @data."\n";
