Here are three relations, $R(A,B)$, $S(C,D)$, and $T(E,F)$. | A | B | | :--- | :--- | | 0 | 1 | | 1 | 0 | | 1 | 1 | | C | D | | :--- | :--- | | 0 | 1 | | 1 | 0 | | 1 | 1 | | E | F | | :--- | :--- | | 0 | 1 | | 1 | 0 | | 1 | 1 | Compute the result of the query: ```sql SELECT A, F, SUM(C), SUM(D) FROM R, S, T WHERE B = C AND D = E GROUP BY A, F HAVING COUNT(*) > 1 ```
