John,
I wouldn't recommend something of the kind on big volumes but I guess
that if you need to load into a spreadsheet it should be OK ... It
assumes boldly that you have more columns in your schema than you need
dates, which is usually the cae.
SQL> select * from t1;
D N
-------- ----------
03/02/01 10
03/03/01 1
03/06/01 8
SQL> select t2.D, nvl(t1.N, 0)
2 from t1,
3 (select t3.minD + rownum - 1 D
4 from user_tab_columns,
5 (select min(D) minD,
6 max(D) maxD
7 from t1) t3
8 where rownum <= 1 + t3.maxD - t3.minD) t2
9 where t2.D = t1.D (+)
10* order by 1
D NVL(T1.N,0)
-------- -----------
03/02/01 10
03/03/01 1
03/04/01 0
03/05/01 0
03/06/01 8
