| Question 448 |
Suppose ORACLE relation R(A, B) currently has tuples {(1, 2), (1, 3), (3, 4)} and relation S(B, C) currently has {(2, 5), (4, 6), (7, 8)}. Consider the following two SQL queries SQ1 and SQ2 :
SQ1: Select *
From R Full Join S
On R.B = S.B;
SQ2: Select *
From R Inner Join S
On R.B = S.B;
The numbers of tuples in the result of the SQL query SQ1 and the SQL query SQ2 are given by:
SQ1: Select *
From R Full Join S
On R.B = S.B;
SQ2: Select *
From R Inner Join S
On R.B = S.B;
The numbers of tuples in the result of the SQL query SQ1 and the SQL query SQ2 are given by:
| 2 and 6 respectively | |
| 6 and 2 respectively | |
| 2 and 4 respectively | |
| 4 and 2 respectively |
