Rose DB subselect (nested query ) on select

Question

I am trying to run a query, that has a subselect in it. I have set up the Manager method, and everything works fine. The only problem is i dont know how to proceed with this query :

SELECT * FROM tableA WHERE 
          name = 'Me' AND 
          class='Tester' AND 
          ( ( Department IN ( SELECT Department FROM 
                                     tableB WHERE 
                                     leader = 'Joe')  
                             OR 
              Leader  in ('','all')  )
         );

Its important to remember that tableA and tableB are 2 different tables . As of now i have reached this query :

my @leader = ('','all');

DB::tableA::Manager->get_tableA ( with_object => ['tableB'] , 
             query => [ name => 'Me',
                        class => 'Tester',
                        OR => [
                              leader => \@leader,
                              Department => [*** this is
     where i have to make the sub select. 
     Dont know how though **** ]
          ]
        ], 
debug => 1);

please help so that i can add that sub query to this main query

Thanks in advance

You can use the clauses function to include arbitrary clauses in the query's WHERE portion.

It would look like this.

DB::tableA::Manager->get_tableA ( with_object => ['tableB'] , 
  query => [ 
    name => 'Me',
    class => 'Tester',
  ],
  clauses => ["( Department IN ( SELECT Department FROM tableB WHERE leader = 'Joe' ) OR Leader  in ('','all') )"
);
