Hy
I want to sum quantites but there is some data that value is negative
but users didn't write the - sign before. I can decide which datas are
negative.
I would like something like that
select sum(moved_quantities) from db
if moving like 'Move-' then sum seem the move is negative
else move value is positive
Is it possible?
If you know which values are supposed to be negative, wouldn't it be
easier to do updates to your data to change all of those values to
negatives? That should only need to be done once. Then use the normal SQL
sum() function to add all of the values together.
