# How to calculate SUM of TotalPrice?

Hello,

I am developing application for mobile. I have database GetExpenses, where I have attributes (Name, Date, Quantity, Price, and I calculated TotalPrice => as Quantity*Price). It is in the 1st and 2nd picture.

My problem is, that I need to calculate TotalPriceSum, but when i will do this, I wiill get errors, as you can see in the next pictures and I lost Expense with my attributes. (picture 3 and 4th).

So, only 1 thing, which I need is to callate SUM(TotalPrice). Can you help me, how to do it?

Sorry, for my English and thank you for your help in advance.

Hello Jakub,

I cannot see the pictures on the link, but getting SUM can be performed in an aggregate by right-clicking the target column and select Sum.

Hope this helps!

But Thank you for help

Hello Jakub,

Best practice for this scenario is to use 2 aggregates; first one does 1st to 2nd pic and second one does 1st to 3rd pic.

Another solution would be to manually sum TotalPrice after your current aggregate, but that takes more load for your screen which is not good.

Hope this helps!

Hi,

I saw the images and got a solution for it. The reason for not showing the other record is, you are using the same aggregate to calculate and show all the data. when you do a Groupby or count Operation, then only that data will show as a result output. to show all the record you have to create another aggregate for it to show the other results for it. If you send me the OML file I can able send you updated one,

Thank you,

Hi,

If you want to be sure that the total amount displayed in the screen is the sum of the displayed lines, you must iterate trough your list and sum the line values.

Two different queries can retrieve the data from different subsets of data, since while you're querying data can be modified in the DB.

Cheers,

Tiago.
