using sign keyword or select case with orientdb to group by positive and negative

Question

Hi I'm trying to do a queries like the ones below in Orientdb

select sum(opening_balance) from account group by opening_balance < 0

select count(opening_balance) from account group by opening_balance < 0

they run but I'm not getting the desired results in both cases it splits the return by the opening_balance value not whether it is negative or positive.

This is on a graph database

This is SQL, so conditions must be in WHERE, not GROUP BY. Furthermore your examples have amount, not opening_balance.
