Aggregation to find a "-1" in an array [message #968222]

Hi,

i'm having a crosstable with 2 groups.
- Group1 Agg1? Agg2? Agg3?
-- Group2 0 -2 -1
-- -1 0 0

In group2 i have different numbers which can be 0, -1 or -2.
I need to aggregate those numbers in group1 and need to know, if there is a "-1" inside the numberlist.

In a simpler way, i have an array of numbers (0, -1, -2) and need a aggregation to find out, if there is a -1 in the array.
Is there a way to do this or is this impossible?

Thanks for your help.

Can you modify dataset? If yes, you can add one column with 0/1 flag (1 if value equals to -1 and 0 otherwise)
