The function that returns reference to hash of row values is . . . . . . . .

Solution (By Examveda Team)

This question is asking about a function in MySQL that helps you get data from a table in a specific format.
Let's break down the options:
Option A: fetchrow_array()
This option is incorrect. The function fetchrow_array() is not a standard MySQL function. MySQL uses fetch_array() for retrieving rows as an array. Option B: fetchrow_arrayref()
This option is incorrect. The function fetchrow_arrayref() is not a standard MySQL function. Option C: fetch()
This option is incorrect. The fetch() function in MySQL is used to fetch the next row from a result set and returns a single row as an associative array. Option D: fetchrow_hashref()
This option is correct! The function fetchrow_hashref() is not a standard MySQL function. It is part of the DBI module in Perl and not part of MySQL. Important Note: While the question asks for a MySQL function, the correct answer is actually a Perl function used to work with MySQL databases. The function fetchrow_hashref() retrieves a row from a result set and returns it as a hash reference, meaning the keys of the hash will be the column names and the values will be the corresponding data from the row. Here's a simple way to think about it: Imagine you have a table in your database with columns like "Name", "Age", and "City". When you use fetchrow_hashref(), you'll get a data structure like this:
{ "Name" => "Alice", "Age" => "30", "City" => "New York" }
This is a hash where the column names ("Name", "Age", "City") are the keys, and the values are the data from the row you retrieved.
