Hi,

I have two columns in table MEMBERFAMILY called MEMBERNO and SPOUSENO.

The Data stored in these columns are as follows

MEMBERNO          SPOUSENO
A-1                         A-2
B-11                       B-101
B-14                       B-114

I need the ouput AS USERNO after sort as under in one column. While sort it is first sorted by alpha and then numeric.

Delimiter "-" is there in all the data

USERNO
A-1
A-2
B-11
B-14
B-101
B-114

If we can rely on a fixed format:
select * from
(select memberno as userno from memberfamily
union
select spouseno from memberfamily
) data
order by left(userno,1), substring(userno, 3, 10)

Only delimiter is constant.
Alpha may be A, CRPB, XYZDDES and so on
Similarly length of number also is not fixed, it may be 0,10023342342, 34 and so on

I was afraid of that. Besides, the secondary sort expression was incorrect.
select userno from
(select memberno as userno, charindex('-', memberno) as idx from memberfamily
union
select spouseno, charindex('-', spouseno)  from memberfamily
) data
order by left(userno,idx), cast(substring(userno, idx+1, 100) as bigint)

So, if alpha includes A, B, and ABC, the order should be?
A
ABC
B

PortletPaul beat me to it (again) but thought I would still post my solution -
select * from
(select memberno as userno from memberfamily
 union all
 select spouseno as userno from memberfamily) as x
order by substring(userno,1,charindex('-',userno)-1),
cast(substring(userno,charindex('-',userno)+1,len(userno)) as int;

In which way is PortletPaul's code to prefer over my much more simple one?

I haven't tested it but his proposed solution does indeed appear to meet the requirements.  
I  can't offer any opinion as to why mine was chosen.

I wish to add is that my suggestion was done without reference to Qlemo's

Suppose equal split between http:#a39177320 and http:#a39177334 would be appropriate.
