I recall that a candidate key can be one of several options for a primary key, but I need to double-check if it has to be unique for every instance.

I remember practicing a question about keys, and I think a candidate key is the one that uniquely identifies each record in a table.

I think a candidate key is something that can potentially be a primary key, but I'm not entirely sure if that's the full definition.

I’m a bit confused; I thought a candidate key was just another term for the primary key, but now I’m not so sure.
