Hello,

in 9i I can write my own aggretate functions. I tried this successfully with a string aggreate and a product aggregate function. However, now I need a special analytic function which multiplies in the partition the values of a column. SUM() OVER... summarizes all values, I need something like MULTIPLY() OVER...
I checked the documentation but I didn't find anything about this. Can I write a custom analytic function? If not, how can I realize something similar with existing functions?

Thanks,
