Suppose now that R(A,B) and S(A,B) are two relations with r and s tuples, respectively (again, not necessarily distinct). If m is the number of (not necessarily distinct) tuples in the result of the SQL query:
R intersect S;
Q. Then which of the following is the most restrictive, correct condition on the value of m?
  • a)
    m = min(r,s)
  • b)
    0 <= m <= r + s
  • c)
    min(r,s) <= m <= max(r,s)
  • d)
    0 <= m <= min(r,s)
Correct answer is option 'D'. Can you explain this answer?

The value of m must lie between the min value of r and s and 0.

The correct condition on the value of m is:

a) m = min(r, s)

This means that the number of tuples in the result of the intersection between R and S is equal to the minimum number of tuples between the two relations. In other words, the result will have at most as many tuples as the relation with the fewest number of tuples.
