i think you also need to add a test for the other months with NOT EXISTS:

-- Created By: Lowell Izaguirre

-- Create Date: |CurrentDate|

-- Description:

-- Modified By: Lowell Izaguirre

-- Modified Date: |CurrentDate|

-- Description:

declare @StartDt DATE

declare @EndDtDATE

SET @StartDt = '2/1/2014'

SET @EndDt = '2/28/2014'

SELECT DISTINCT T1.YOURCUSTOMERID

,T1.YOURCUSTOMERNAME

FROMYOURTABLE T1

WHERET1.YOURDATECOLUMN BETWEEN @StartDt AND @EndDt

AND NOT EXISTS (SELECT 1

FROM YOURTABLE T2

WHERE T1.YOURCUSTOMERID = T2.YOURCUSTOMERID

AND (T2.YOURDATECOLUMN < @StartDt OR T2.YOURDATECOLUMN > @EndDt )

)

Thats where the NOT EXISTS comes into play which Lowell posted. If any of your customers have records outside the range they will be elminated from the results.
