Get all automatically generated values after insert

Question

After inserting a new row into a database table it is possible to get the value of the generated primary key like this:

PreparedStatement statement = connection.prepareStatement(query, Statement.RETURN_GENERATED_KEYS);
ResultSet keys = statement.getGeneratedKeys();

But how can I retrieve other automatically generated values that are not keys. Lets say my table definition looks like this:

CREATE TABLE foo (
    id INT PRIMARY KEY AUTO_INCREMENT,
    changed TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

Is it possible to get the value of the column changed without the need to query the database again with the returned primary key?

Answer 1

no, data change statements INSERT, UPDATE do not return values of the fields changed/inserted. You can ask for the last key but even that is an additional DBMS call.
