What potential issue might occur if you do not specify the column names correctly in a PHP database query?

If you do not specify the column names correctly in a PHP database query, you may encounter errors such as "Unknown column" or "Column not found". To solve this issue, make sure to double-check the column names in your query to match the actual column names in the database table.

// Incorrect column names in the query
$query = "SELECT id, namee FROM users";

// Corrected column names in the query
$query = "SELECT id, name FROM users";
