Question

Relation R1 has 10 tuples and 5 attributes.
Relation R2 has O tuples and 7 attributes. When a
CROSS JOIN' is achieved between R1 and R2, how
many tuples would the resultant set have?​

Answer 1

When a CROSS JOIN is achieved between R1 and R2, 0 tuples the resultant set will have 0.

tuples would the resultant set have zero.

Answer 2

Given,

The relation R1 has $\[10\]$ tuples and $5$ attributes.

The relation R1 has 2 tuples and 7 attributes.

Solution,

Know that a cross join is one that returns the Cartesian product of rows from the tables consideration.

Therefore, the cross join of R1 and R2 is zero.

Hence, the cross join of R1 and R2 is zero.
