1. Object Type Support: In this version, member functions are supported, but not yet MAP member functions.
create or replace type mf_test as object
(
name varchar2(30),
member function disp return varchar2
);
create or replace type body mf_test as
member function disp return varchar2 is
begin
return 'Name : '||name;
end;
end;
edb=# declare
edb-# v_mf mf_test;
edb$# begin
edb$# v_mf := mf_test('Raghavendra');
edb$# dbms_output.put_line(v_mf.disp());
edb$# end;
Name : Raghavendra

2. Pl/SQL sub types : Now we can define own subtypes in the declarative part of any PL/SQL block, subprogram, or package.
Syntax: SUBTYPE subtype_name IS base_type[(constraint)] [NOT NULL];
declare
subtype hiredate is date not null;
pfdate hiredate := sysdate;
begin
dbms_output.put_line(pfdate);
end;

3. DROP TABLE CASCADE CONSTRAINTS: This option will delete all foriegn key constraints that referencing the table to be dropped, and then drops the table.
edb=# create table master(id int primary key);
edb=# create table master1(id int references master(id));
edb=# d master1
Table "enterprisedb.master1"
Column | Type | Modifiers
--------+---------+-----------
id | integer |
Foreign-key constraints:
"master1_id_fkey" FOREIGN KEY (id) REFERENCES master(id)
edb=# drop table master cascade constraints;
NOTICE: drop cascades to constraint master1_id_fkey on table master1
DROP TABLE
edb=# d master1
Table "enterprisedb.master1"
Column | Type | Modifiers
--------+---------+-----------
id | integer |
4. TYPE’s in Package definition:
create or replace package t_pack as
type ftype is record(name varchar2(20));
end;
edb=# call t_pack.ftype('EDB');
ftype
-------
(EDB)
(1 row)
5. TABLE() function call on Nested tables: A TABLE() enables to query a collection in the FROM clause like a table.
CREATE OR REPLACE TYPE string_a IS TABLE OF VARCHAR2(765);
select * from table(string_a('abc','xyz')) ;
column_value
--------------
abc
xyz
(2 rows)
6. IN/OUT of UDT in function call: The functions udtabletype_in and udtabletype_out are now supported for nested tables.
7. Usage on reserved Keywords(LOG/CURRENT_DATE): Now LOG word can be used for naming the function. Also CURRENT_DATE, can be used for variable names.
edb=# create or replace function log(t text) return text as
begin
return t;
end;
edb=# select log('EDB');
log
-----
EDB
(1 row)
edb=# declare
edb-# current_date date := '07-OCT-2012';
edb$# begin
edb$# dbms_output.put_line(current_date);
edb$# end;
07-OCT-12 00:00:00
EDB-SPL Procedure successfully completed
8. STRING /NVARCHAR2 datatype support: Now STRING datatype and NVARCHAR2 for multi-byte data is supported for table column. String aliased to VARCHAR2 and NVARCHAR2 maps to varchar of PPAS data-types.
edb=# create table dtype( a string, b nvarchar2);
CREATE TABLE
edb=# d dtype
Table "enterprisedb.dtype"
Column | Type | Modifiers
--------+-------------------+-----------
a | character varying |
b | character varying |
