Finding accounts where child does not match Parent acct category

Question

Hi,
I have an interesting problem. There is Parent Account Group with child accounts under it. The child accounts must
have been assigned the SAME category as the Parent account. If they are not, then they must show-up on the mismatch report.
So, if there is a Parent Acct 1 with childacct a AND childacct b and if childacct a has category of Base and childacct b has category of offshore, while Parent Acct 1 has category of Base, then because BOTH A AND B do NOT have the same category as assigned to its parent, it should show up on report.
I can get all children but how do this: check if any ONE acct category is NOT the same as the Parent???
DO I have to use If AcctCATPARENT <>ANY(CHILDcate). then select Acct ID from table ....will this work??
This is urgent, any help is appreciated!!
Regards,

Hello
if you have a problem please remember to post some create table statements along with inserts to provide sample data to work with. Also, remember to show what the output is you're expecting and what you've tried so far. And finally remember that this is a volunteer forum so there aren't any urgent requests.
anyway, isn't it just a matter of joining between parent and child?....
WITH parent_acc AS
(    SELECT 1 ID, 'cat a' cat FROM dual UNION ALL
     SELECT 2 ID, 'cat b' cat FROM dual UNION ALL
     SELECT 3 ID, 'cat c' cat FROM dual UNION ALL
     SELECT 4 ID, 'cat d' cat FROM dual
child_acc AS
(   SELECT 1 ID, 1 parent_id, 'cat a' cat FROM dual UNION ALL
    SELECT 2 ID, 1 parent_id, 'cat a' cat FROM dual UNION ALL
    SELECT 3 ID, 2 parent_id, 'cat b' cat FROM dual UNION ALL
    SELECT 4 ID, 2 parent_id, 'cat b' cat FROM dual UNION ALL
