Hi, Sandor. no_rec_version is exotic mode - reading transaction can
see only last version of the record, if it is not commited you'll get
lock conflict even on Select. rec_version - on Select transaction see
last commited version and conflict will be only on update record that
have non-commited yet new version.

Best regards.
