Question 21

4 March 2025 · Computer Science (083)

Assertion (A): We can retrieve records from more than one table in MYSQL. Reason (R): Foreign key is used to establish a relationship between two tables.

Answer

(b) Both A and R are true but R is not correct explanation

Explanation

Both statements are true. Joins allow retrieval from multiple tables. Foreign keys link tables. However, the ability to join isn't solely explained by the definition of a foreign key.
