Which flags have value -1 when all selected and which ones don't?

Question

In AzerothCore/TrinityCore DB some flags (bitmask values) have resulting value -1 when all bits are enabled, while other flags don't.

Is there a list of such flags so I can distinguish the 2 groups?

For example creature.spawnMask does NOT have -1 when all flags selected.

Answer 1

Answer from Shauren on Discord:

to be able to insert -1 to database, it means the field must be signed which gets super annoying when you actually have a flag that occupies the highest bit so answering the original question no field. its a bug if it works

It looks like no flags should have value -1 when all bits selected.
