Hi All,
I am working on reporting module where I need to order by the alphanumeric values.
Example:
create table #temp
(
Response varchar(500)
);
insert into #temp values(0)
insert into #temp values(1)
insert into #temp values(2)
insert into #temp values(10)
insert into #temp values(3)
insert into #temp values('ABC')
select response from #temp order by ascii(response) asc;
Output:
0
1
10
2
3
ABC
Expected output:
0
1
2
3
10
ABC
Ascii value for 10 and 1 is same that's why I am not getting the expected result.
Is there any way to resolve this?

Will this do

select * from #temp order by case when isnumeric(response)=1 then convert(integer,response) else 99999999999 end,response

another way to do the same thing is to order by the length, then by the column:

select * from #temp order by len(Response),response

...well not the same thing, but similar...with the example data set it's the same results, but if there was a single character 'Z' in the table, the numbers would not be in order any more. it depends on what youy are after, i guess.

Ummm... be careful... try it with the value like '1e2'. Never use "IsNumeric" as an "IsAllDigits" function because it's not. 😉

Using code very similar to Dave's otherwise great example, try this...

create table #temp

(

Response varchar(500)

);

insert into #temp values(0)

insert into #temp values(1)

insert into #temp values(2)

insert into #temp values(10)

insert into #temp values(3)

insert into #temp values('ABC')

insert into #temp values('AB')

insert into #temp values('A')

insert into #temp values('1EA')

insert into #temp values('1E2')

SELECT * FROM #temp ORDER BY CASE WHEN Response LIKE '%[^0-9]%' THEN 99999999999 ELSE CONVERT(INTEGER,Response) END, Response
