What you're describing is a cursor, but they're generally not the best way of processing data.

If you post what you need to do with each record, I'm sure there are plenty of people here who can help you avoid using a cursor (myself included).

Ok, so because the WHERE clause changes, you feel like you want to run each contactperiod separately.

So try:

and
(
DATEPART(hh,CP.StartTime)>=21 and DATEPART(hh,CP.StartTime)<=24 and CD.DateDrawn=DateADD(d,1,@CurrentTime)
or
NOT (DATEPART(hh,CP.StartTime)>=21 and DATEPART(hh,CP.StartTime)<=24) and CD.DateDrawn=@CurrentTime
)

instead of that line that changes (the "and CD.DateDrawn=@CurrentTime" line)

ie:


select CP.StartTime, C.ContactID, C.Product_VoicemailPhone, TMP.TextMessageEmail, C.Product_TextMessagePhone, C.Product_Email
       from dbo.tblContact C
              inner join dbo.tblContactPeriod CP on C.ContactPeriodID = CP.ContactPeriodID
             inner join dbo.tblColorDrawn CD on CD.ColorID=C.ColorID
              left outer join dbo.tblTextMessageProvider TMP on TMP.ProviderID = C.Product_TextMessageProviderID   --outer join because not everyone selects Text Messages.
       where DATEPART(hh,dbo.ConvertToGmt(CP.StartTime, C.Timezone, C.DST)) = DATEPART(hh,@GmtServer)
              and IsActive = 1
              and @CurrentTime >= StartDateService
              and
              (
              DATEPART(hh,CP.StartTime)>=21 and DATEPART(hh,CP.StartTime)<=24 and CD.DateDrawn=DateADD(d,1,@CurrentTime)
              or
              NOT (DATEPART(hh,CP.StartTime)>=21 and DATEPART(hh,CP.StartTime)<=24) and CD.DateDrawn=@CurrentTime

Rahu,

Cursors are generally NOT the right answer.
