Invalid unique or primary key constraint - a key is a subset of another key
This message appears when an ALTER TABLE statement attempts to add a UNIQUE or PRIMARY KEY constraint that includes a column already participating in a UNIQUE constraint.
A column can participate in at most one UNIQUE constraint, and a column that is part of a UNIQUE constraint cannot also be part of a primary key.
