Return all generated keys for inserts

See original GitHub issue

If multiple values are inserted with Statement.RETURN_GENERATED_KEYS set, driver returns only the last generated key/identity value on calling getGeneratedKeys. But according to JDBC spec,

The ResultSet object returned by getGeneratedKeys will contain a row for each value that a statement generated.

This is a limitation from SQL Server’s end and there’s not much the driver can do. After speaking with the SQL Server team, changing the server response to return all generated keys instead of the last one (similar to OracleDB for example) would not be a trivial task, and the change likely won’t be made as it will break a lot of existing design. However, we’re keeping this issue open for future references.

@stolsvik please re-read comment above that this is a SQL Server limitation. This issue is left open for tracking purposes only the driver team is not going to be implementing any hacks to workaround. This is filed in our backlog we will look into supporting when SQL Server addresses the limitation.
