Heh... Mom always said, "Never run with scissors"... being in a hurry on code has the same effect on careers.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

declare @DateFrom DateTime = CONVERT(DATETIME, '01/01/2014', 103)

declare @DateTo DateTime = CONVERT(DATETIME, '01/03/2014', 103)

;WITH CTE(dt)

AS

(

Select @DateFrom

Union All

Select DATEADD(d,1,dt)FROM CTE

Where dt<@DateTo

)

select DayName,CONVERT(varchar(50), dt, 103)as Date from (select 'Saturday' as DayName,dt from CTE

where DATENAME(dw,dt)In('Saturday') group by dt

Union

select 'Sunday'as DayName,dt from CTE

where DATENAME(dw,dt)In('Sunday'))as result order by dt

Please read the following article for why you should generally avoid rCTEs that "count" by 1 like yours does. There are several much more efficient ways to do the same thing.
