Seema,

The following would work (there will be better ways to do it especially if you're on Oracle 8) but I'm stuck with 7.3. You'll need to have access to a table which will always have at least have 15 rows (I've used all_objects here).

SELECT day, COUNT(*)
FROM table_name,

     (SELECT ROWNUM day
          FROM ALL_OBJECTS
          WHERE ROWNUM < 16)

WHERE day BETWEEN sday AND eday
GROUP BY day

Hi
I need help to get query
sno is primary key of table

sday and eday will be between (1 and 15)

rowno, sday eday

1       2       5
2       4       4
3       4       5
4       8       9
5       9       10

the "day" output will be the no which can be equal to sday or equal to eday or between sday and eday

we should get output as

day     count
2       1 ( in row 1, 2 is equal to sday )
3       1 ( it is in row 1, b/n 2 and 5 )
4       3 ( in row 2,3 equal to sday and eday ,and b/n 2and5 in row 1 )
5       2 like that...
8       1
9       2
10      1

Thanks
Seema
