I got this question by my school teacher while I was bunking the class.

I want to ask this question from Database Copies topic in section Nulls and Conditions and Miscellaneous of MySQL

Answer 1

The correct answer is (d) fetchrow_hashref()

Best explanation: The function ‘fetchrow_hashref()’ returns reference to hash of row values. ‘fetchrow_arrayref()’ returns a reference to an array of row values. ‘fetch()’ is the same as fetchrow_arrayref().
