Is there a typo in your question? It looks like you want the following to be returned, unless I have misunderstood:

ID Stat StatDate

1 AppRec 2012-12-01

1 AppCom 2012-12-02

If so, this will do it:

SELECT ID, Stat, StatDate

FROM Apps

WHERE ID IN (SELECT ID FROM Apps WHERE Stat = 'AppRec' AND StatDate >= '2012-12-01')
