Hi All,

I have table like below but i need to calculate divison of two columns based on group by deptno,locationid,pid,sid.But here i have different empids.I need output mentioned below.Here empids are staticand those will not change.For particular combination of group by columns will get only 2 empids or some time may be will get only 1.so in that case anything by null or zero should be zero.
