Counting horizontal value and generating date

Question

using oracle 9i,
I have a table called test which has
Eno     pct1     pct2     pct3     pct4     pct5     sal_date
101     0     100     0     100     100     03/01/2010
102     0     0     100     100     100     14/02/2010
103     0     100     100     100     100     24/01/2010for first row,we have two zeros for pct1,pct3,so the two records to be generated for 03/01/2010 and next week as well
Eno     pct1     pct2     pct3     pct4     pct5     sal_date
101     0     100     0     100     100     03/01/2010 (2 Zeros,two weeks to b generated
