Question

‘fetchrow_hashref()’ returns a reference to the hash of row values keyed by what?

(a) row name

(b) column name

(c) table name

(d) database name

This question was posed to me in a job interview.

I need to ask this question from Operators in portion Data Type Reference, Operators and Functions of MySQL

Answer 1

The correct option is (b) column name

The best I can explain: The function ‘fetchrow_hashref()’ returns a reference to the hash of row values, keyed by the column name. The function ‘fetchrow_arrayref()’ returns a reference to an array of row values.
