See #3066 (comment) and #2958 (comment) for the source.

Summary:

  1. FetchMode::STANDARD_OBJECT and FetchMode::CUSTOM_OBJECT are no longer supported.
  2. FetchMode::COLUMN with a non-zero index is no longer supported.
  3. Incompatible change in the Connection::fetchColumn() signature where the 3rd argument is now $types, not $columnIndex.

Reasoning:

  1. The object fetching modes exist only for parity with PDO. Fetching an object from DBAL is a poor man solution to object hydration. It works only if the DB schema and the object's properties are tightly coupled together and makes decoupling harder (see example).
  2. It's not implemented in the MySQL driver and in the caching layer without demand which means that it doesn't bother consumers.
  3. Fetching of a non-zero column is a sign of bad practice of selecting more data than needs to be fetched. Not implemented in fetch() and fetchAll() in any of the non-PDO drivers and in the caching layer.
  4. Getting rid of the above lets us get rid of the variadic $args in fetch statement methods and therefore simplify the interface.
