In the given PHP code, what improvements can be made to avoid the error "Unknown column 'datum' in 'field list'"?

The error "Unknown column 'datum' in 'field list'" indicates that the column 'datum' is not present in the database table being referenced in the SQL query. To fix this issue, ensure that the column 'datum' exists in the table. Additionally, double-check the spelling of the column name to avoid any typos.

// Correcting the column name to 'date' instead of 'datum'
$sql = "INSERT INTO events (event_name, date, location) VALUES ('$event_name', '$date', '$location')";
