What are the potential pitfalls of handling data aggregation in SQL rather than PHP?

One potential pitfall of handling data aggregation in SQL rather than PHP is that it can be less flexible and harder to customize the aggregation logic. To solve this issue, you can retrieve the raw data from the database using SQL and then perform the aggregation and any additional processing in PHP, giving you more control over the process. 

// Retrieve raw data from the database using SQL
$query = "SELECT column1, column2 FROM table_name";
$result = mysqli_query($connection, $query);

// Initialize variables for aggregation
$total = 0;

// Perform aggregation in PHP
while ($row = mysqli_fetch_assoc($result)) {
    // Perform aggregation logic here
    $total += $row['column1'] * $row['column2'];
}

// Output the aggregated result
echo "Total: " . $total;
