Is there a known issue with MySQL versions that could cause the error message "Unknown column 'col1' in 'field list'" when using PDO?

The error message "Unknown column 'col1' in 'field list'" typically occurs when the specified column does not exist in the table being queried. This could be due to a typo in the column name or an issue with the database schema. To solve this issue, double-check the column name in the query against the actual column names in the database table. 

<?php
// Assuming $pdo is your PDO connection object
$stmt = $pdo->prepare("SELECT col1, col2 FROM table_name");
$stmt->execute();

// Fetching results
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    // Process the retrieved data
}
?>
