Relational table model Calulation

[aekilic]

Dear All

Is there any possible way to make any calculations in a relational table mode?

[wysota]

Not without subclassing the model or setting a proxy model that does the calculations.

[aekilic]

is there any examples that could help us?

[wysota]

What kind of example do you require?

[aekilic]

We are dealing with a table that will multiply a coulmn with a coulmn and at the end it will take the sum of it?

Can't you do it using SQL?
