Do you want these as separate recordsets? Is that what you're looking to do? Or are you looking for them in a particular order as a single recordset?

I want them in seperate record sets.
Thanks.

I feel like I'm over simplifying these things, because someone usually follows up my code plops with a set-based solution.
If you want separate recordsets, though, would this (over-simplified and non-robust code) work for you?
CREATE TABLE #tblSort (
Num int,
Letters varchar(64))
/*
INSERT STUFF
*/
DECLARE @MinOfSet int,
@NextMinOfSet int,
@LastMin int,
@NextMin int,
@MaxOfTable int
SET @MinOfSet = 0 --Assuming a non-zero value for simplicity.
SELECT @MaxOfTable = Max(Num)
FROM #tblSort
SELECT @MinOfSet = Min(Num)
FROM #tblSort
WHILE @MinOfSet <= @MaxOfTable
BEGIN
SELECT @NextMinOfSet = Min(Num)
FROM #tblSort
WHERE Num > @MinOfSet
SELECT *
FROM #tblSort
WHERE Num IN (@MinOfSet,@NextMinOfSet)
ORDER BY Num, Letters
SELECT @MinOfSet = Min(Num)
FROM #tblSort
WHERE Num > @NextMinOfSet
ENDHTH,

DROP TABLE #tblSort

Ah, so that's where all those dratted smileys went.

Try this:
DECLARE @n int
SET @n = (
SELECT min(no)
FROM test
)
WHILE @n is not null
BEGIN
SELECT * FROM test WHERE no = @n OR no = @n + 1
/** Choose: (wasn't sure which way you wanted it)
SET @n = (
SELECT min(no)
FROM test
WHERE no >(@n+1)
)
--OR--
SET @n = @n + 2
**/
END
