Problem using Order by in forms 6i

Question

Hi
The forms version I have 6.0.8.14.
I trying to write a query that looks like this
select * from (
select rownum, a.*
from (select x , y, z from xyz_table
order by x, y asc)
) b
order by b.z
The form does not compile and gives errors pointing to the order by clause order by x, y asc.
Can anyone tell me why this happens and the solution for this.
Thanks

I don't have any issue to do your SQL(revise it a bit),
select * from (
select rownum AS row_num, a.*
from (select x , y, z from xyz_table
order by x, y asc) a
) b
order by 4
What I did is first use wizard to build a tabular form based on the table xyz_table, then manually add a column called ROW_NUM, then on the block's property, replace the table name xyz_table with (above sql), then it works well.
don't forget the '()'.
Also, you have to change the column name to not be the ROWNUM.
My forms builder version is Forms [32 Bit] Version 6.0.8.11.3 (Production).
