how to use aggregates fields with unidac and firebird?
any example?

Please specify what is the essence of your question and what do you mean by the phrase "aggregates fields".

I need a table field to be automatically calculated every time I log in, that is, add the items to each entry in cached update mode without having to do a while loop

If you need to use calculated fields in the dataset, then you can easily use them both in the CachedUpdates mode and without it. If you need to use the calculated fields at the database level - this question relates mostly to the architecture of your application and the functionality of the DBMS, rather than the UniDAC functionality. Therefore, to get an answer to your question, you can refer to the DBMS documentation or ask a question on the relevant forums. Regarding the functionality of our components, more specifically the use of the CachedUpdates mode, please make a small example without using the CachedUpdates mode and send it to us using the contact form https://devart.com/company/contactform.html, including scripts for creating and filling database objects.

uniquery has support for aggregate fields ?, tried in several ways and always says that it is not possible to execute

In order for us to be able to give you a detailed answer, we need to have a sample demonstrating the specified behavior. Therefore, please compose a small sample demonstrating the described behavior and send it to us using the contact form https://devart.com/company/contactform.html, including the scripts for creating database objects.
