How to get resource overload values ​​from the Project Sever database?

Question

Project management

Hello. I have been struggling with the problem for more than one day: how to extract employees with excess availability from the Project Server database using a SQL query? Does it even have a calculated field with these values? There is a field in the assignment table "AssignmentIsOverallocated", which is a flag that indicates an overload. But it's not clear which fields it does this on the basis of.
