Is there a way to create a foreign key on two columns that reference the same PK in another table?
Both of these columns are related to the PK.
Here is what I have:
CONSTRAINT some_FK FOREIGN KEY (col1, col2) REFERENCES table(col_PK);
But I keep getting the following error:
ORA-02256: number of referencing columns must match referenced columns
You want two different foreign keys:
CONSTRAINT old_player_fk FOREIGN KEY (old_player_id) REFERENCES player(id),
CONSTRAINT new_player_fk FOREIGN KEY (new_player_id) REFERENCES player(id)
