Not getting full series multiplication (product) in CONNECT-BY query
What you need is cumulative multiplication. But there is no such function either as Aggregate or Analytical function. But maths tells us multiplication can be changed to addition using logarithm. a * b = exp(ln(a) + ln(b)) Use this in SUM as analytical function. No need to use CONNECT BY...
