Please
respond to
ORACLE-L
I have a table with a number column(Col A).I want to display A-1.There could
be some negative values in
this A-1 column.But I want to display 0 whereever negative value appears.I
can use the ROUND(A-1) but this
will round the other positive value to the next positve integer which I
don't want to happen.
select a,a-1,round(a-1) from t;
A A-1 ROUND(A-1)
----- ---------- ----------
3 2 2
1 0 0
.6 -.4 0
.8 -.2 0
6 5 5
3.5 2.5 3
.69 -.31 0
2.7 1.7 2
sum 10.29------>this value is the sum of all the negative and
positive numbers
I want the o/p to be like this.The decimal numbers should not be rounded off to the next number.
select a,a-1,round(a-1) from t;
A A-1 MY REQUIREMENT
----- ---------- ----------
3 2 2
1 0 0
.6 -.4 0
.8 -.2 0
6 5 5
3.5 2.5 2.5
.69 -.31 0
2.7 1.7 1.7
Sum 11.2(My REQUIREMENT)
My requirement is to compute the sum of the columns for exact value i.e I want the sum of only the positive numbers(negative numbers should not be counted for the sum that's why I want to display 0 for negative value as the sum function adds all the positive and negative numbers)
How can I do this
Thanks
Ravindra
