hey trying to rename a header on the pivot,
The month is stored as int type, can i convert it to month name (jan, feb, march) across the top of the pivoted table instead of numbers?

how would i go about this? 

Example:
SELECT*

FROM Table1

PIVOT(

MAX(Score)

FOR[Month]IN([1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12]))

AS p
 
 Thanks!

P.S. Not sure I really know what you mean by using 'AS'. I'd probably go with something like:

SELECT *
FROM (SELECT DateName(Month, DateAdd(Month, [Month], 0) - 1) as [MonthName], Score FROM Table_1) AS SourceTable
PIVOT (Max(Score) FOR [MonthName] IN ([January], [February], [March], [April], [May], [June], [July], [August], [September], [October], [November], [December])) AS PivotTable

but keen to see other approaches.

turns out i havnt got it sorted haha, your method didn't work above as i have it saved as a varchar not date type. 

The method i was trying was to use was
SELECT Month [1] As Jan, [2] as Feb etc

but it didn't work as there not columns till after being pivoted, so i get a non existent column error.
