RatingTable Schema

The table has user ratings of items.

Column Data Type Description
userid_column INTEGER User identifier.
itemid_column INTEGER Item identifier.
rating_column Any numeric type. Rating user gave item.

If the same user rates the same item more than once, the function might select any one of those ratings for that user-item combination; therefore, function results are nondeterministic even with the UniqueID argument.
