I m using this query in SQL (TOAD) it is working fine
and also when I create report in Tabular it also work accordingly,
I have DOC_NO varchar2(10)
and store data in 1 ...50 record like serial no.
but when I create report with GROUP ABOVE data not sorting ?
select a.doc_no,a.v_name,a.loa,a.beam,a.dwt,a.bert_date,a.sale_date,a.total_hours,a.sh_name,a.s_name,a.bl_qty,
        b.p_name,b.r_name,b.rec_qty 
from cargo_handle a, sub_cargo_handle b
where a.doc_no = b.doc_no
and a.bert_date between :dd1 and :dd2
order by to_number(a.doc_no)

Answer 1

The ordering in groups is controlled by the Break Order property. You cannot use order by in your query. See the online help:
The order of column values in a default group is determined by the ORDER BY clause of the query for SQL queries and by the sort column for Express queries. For column values in user-created groups, however, you must use Break Order to specify how to order the break column's values.
