## Remarks

- The data set is identified by `expdataset.dataset.id`; the whole definition is replaced.
- Requires a vault session and the vault right `see_all_objects`. Without the server right
  `run_code`, the connection string may change only in its credentials, and only with the vault
  right `run_signed_code` (part of full control); pointing it to another data source fails with
  "Access denied.".
