Yes. Always. It must be. There can be no change nor discussion on this point. The parent of your so-called VALUES clause originates from the usage in an INSERT statement. It has just been generalized to not require an `INSERT INTO` prefix. `INSERT INTO x VALUES (1), (2), (3) ...;` is absolutely nothing more than semantic sugar for: ``` INSERT INTO x VALUES (1); INSERT INTO x VALUES (2); INSERT INTO x VALUES (3); ... ``` Therefore the processing of the list of values sets *must* be left-to-right (in order specified).
