The best I can think of is a VARRAY, though you cannot access
it by index in SQL (you need a stored procedure or client API
for that). Quite clumsy.
Example:
SQL> CREATE TYPE VARCHAR_A AS VARRAY(100) OF VARCHAR2(10);
2 /
Type created.
SQL> CREATE TABLE N(ID NUMBER(10,0) PRIMARY KEY, A VARCHAR_A);
Table created.
SQL> INSERT INTO N VALUES (1, VARCHAR_A('one', 'two', 'three'));
1 row created.
SQL> SELECT A FROM N WHERE ID=1;
A
------------------------------------------------------------------------
--------
VARCHAR_A('one', 'two', 'three')
SQL> SELECT X.* FROM N, TABLE(N.A) X WHERE ID=1;
COLUMN_VALUE
----------------------------------------
one
two
three
