Hi,I have a little problem and i dont know how to solve it.

I have a query that returns a list of names that are always the same ones,for example:

'Literature'
'Mathematics'
'Science'
'Chemistry'
...

My problem is that i want to order this result just like i wrote it,so i can't use order by that column. Anyone know a way to that?

Thanks!

Please have a look at the rownum function as in:

select rownum, owner, table_name from all_tables

Cheers,
Dan

You might be better off by looking at the address of each row.
Please try:

1) select rowid from your_table;

2) select rowidtochar(rowid) from your_table;

3) select rowidtochar(rowid) from your_table order by rowidtochar(rowid);

Cheers,
Dan

Code:

order by 
case subject
when 'Literature' then 1
when 'Mathematics' then 2
when 'Science' then 3
when 'Chemistry' then 4 end

If you have a version that does not support case expressions, you can use the decode function.
