How To Get Only Month or Only Year from datetime format of yyyy-mm-dd

Hi SQL gurus,

I have field has datetime format of yyyy-mm-dd (ie. 2014-11-28).  Could anyone please educate me on how to extract only month (ie. November but not 11) and only year (ie, 2014) from 2014-11-28.  I writing two report have title of Number of sick leaves on November  and Number of sick leaves in 2014.  I am planning to extact 11 from 2014-11-28 and display as November on report title and the same goes for 2014.  Unless you have better non complicated way.   Thank you very much in advance.  DingDong!!
