Bulk update

I want to increase a property for multiple objects at the same time.
For example, I have a list of employees and I need to increase their salaries with 100$.
Is it possible to do this?

Yes, you can do that. Please see the documentation (search for “bulk update”):

https://backendless.com/documentation/data/rest/data_updating_data_objects.htm

I saw the documentation, but I didn’t find that. I saw how to update multiple objects with a new value, but I didn’t find a way to update objects using the old properties values (for example adding 100$ to each employee’s salary). Could you, please, tell me how can I do this?

Hi, Maria.
Such bulk update operation is not available. But you could fetch the whole collection and then iterate through it.
