Is there an Oracle equivalent to SQL Server's OUTPUT INSERTED.*?

In SQL Server, you can do things like this:

INSERT INTO some_table (...) OUTPUT INSERTED.*
VALUES (...)

So that you can insert arbitrary sets of columns/values and get those results back. Is there any way to do this in Oracle?

The best I can come up with is this:

INSERT INTO some_table (...)
VALUES (...)
RETURNING ROWID INTO :out_rowid

...using :out_rowid as a bind variable. And then using a second query like this:

SELECT *
FROM some_table
WHERE ROWID = :rowid

...but this isn't quite the same as it returns everything within the column, not just the columns I inserted.

Is there any better way to do this without using a lot of PL/SQL and preferably with only one query?

Maybe I don't understand the question, but wouldn't this do it? (you must know what you want back)

INSERT INTO some_table (...)
VALUES (...)
RETURNING some_column_a, some_column_b, some_column_c,  ...  INTO :out_a, :out_b, :out_c, ...

@Vincent returning bulk collect into for multi-row insert works only in conjunction with forall (in another words if you insert from collection you can retrieve "results" into another)

The RETURNING clause supports the BULK COLLECT INTO synthax. Consider (10g):

SQL> CREATE TABLE t (ID NUMBER);

Table created
SQL> INSERT INTO t (SELECT ROWNUM FROM dual CONNECT BY LEVEL <= 5);

5 rows inserted
SQL> DECLARE
  2     TYPE tab_rowid IS TABLE OF ROWID;
  3     l_r tab_rowid;
  4  BEGIN
  5     UPDATE t SET ID = ID * 2
  6      RETURNING ROWID BULK COLLECT INTO l_r;
  7     FOR i IN 1 .. l_r.count LOOP
  8        dbms_output.put_line(l_r(i));
  9     END LOOP;
 10  END;
 11  /

AADcriAALAAAAdgAAB
AADcriAALAAAAdgAAC

AADcriAALAAAAdgAAE

It works with multi-row UPDATE and DELETE with my version (10.2.0.3.0) but NOT with INSERT:

SQL> DECLARE
  2     TYPE tab_rowid IS TABLE OF ROWID;
  3     l_r tab_rowid;
  4  BEGIN
  5     INSERT INTO t (SELECT ROWNUM FROM dual CONNECT BY LEVEL <= 5)
  6      RETURNING ROWID BULK COLLECT INTO l_r;
  7     FOR i IN 1 .. l_r.count LOOP
  8        dbms_output.put_line(l_r(i));
  9     END LOOP;
 10  END;
 11  /

ORA-06550: line 7, column 5:
PL/SQL: ORA-00933: SQL command not properly ended

Maybe you have a more recent version (11g?) and the BULK COLLECT INTO is supported for multi-row INSERTs ?
