output returning without sort:

period     value -------------------- april         4750 august        4750 december    187250 february      4000 january      12500 

desired output after sorting month:

period      value  ----------------------- january     12500 february     4000 april        4750 august       4750 december   187250

don't mess around names of date's part!

any approach build full date using month's name , date fragment in order month's number fail, if executing system has got different language. if application might ever run in international environment, must find way deal without hacks.

if period real date somewhere, might extract year , month using year() , month() , order both of them. both come numeric index.

but solution seems simpler:

obviously using dates table (which thing!)

from posted example take, column [monthofyear] has got numeric month index. , you've got fiscalyear too. include these columns query , use order fiscalyear,monthofyear.
