-- You may need to extend the range of the virtual tally table.

SELECT [QuarterName] = 'Q' + DATENAME(qq,DATEADD(QQ,n,startdate)) + ' ' + CAST(YEAR(DATEADD(QQ,n,startdate)) AS VARCHAR(4))

FROM (SELECT startdate = '01/JUN/2011', enddate = '31/DEC/2013') d

CROSS APPLY (

SELECT TOP(1+DATEDIFF(QQ,startdate,enddate)) n

FROM (VALUES (0),(1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12)) rc(n)

) x
