Sum Positive and negative values in same Field

[DaRTHY]

Hello friends;

Im trying to get sum "+" and "-" Values in same Field. I created new Expression Builder in Query and i wrote there :

A: Sum([tablename]<0)

of course it did not work.

how shall i update my expression to work this thing ?

Ty for your helps.

you probably need a query to select the negative items

sum(amount) where amount<0

but you won't get both in the same query with that.

you could add a group by with this sort of syntax. This will give you totals of each group, and you would have 2 groups, positive and negative. I am not used to writing SQL directly, but this sort of thing.

sum(amount) groupby (amount>0)

Not sure I follow, but if you want to add both the positive and negative numbers then you just use Sum([TheField])? Or they separate fields?

okey. I guess i wrote there wrong. I have a field and there + and - values.

i want to sum up negative value with other negative values and positive value with other positive values.

And i ll use these in Bar Chart after i sum these Values. For bar chart i shall separate positive and negative values. (at the same time i want to sum them too...)

hope so i could explain myself better at this time. Im sending as a picture my field.

* First you want to identify the positive and the negative values in a field, something like:

ValueType: IIF([Field] < 0, "Negative", "Positive")

... I'm guessing you class 0 as a positive value.

* Next you click the Totals button and Sum() the field GROUPing BY ValueType.

SELECT Sgn(amount) AS Sign, Sum(amount) AS SumOfAmount
FROM table
GROUP BY Sgn(amount)

Good call with Sign Galaxiom, almost forgetting my trig.

im so bad to explain myself or im so bad to understand. (after 7 hours nonstop working. its really hard to write smthing as english for me.

for my picture there are 2 - Value and
-152.400,00+(-70,00) = -152.470,00 this is for negative...
same thing for positive too 3.525,00+36.941,00+462.083,00 = 502.549,00
and these results i need in new Field thats why i used Build expression.

sry if i steal your time for my bad.
