Oracle 8.0 Features

8.0 Features

Returning into clause:
Used to return the values thru " DML" stmts.
Used with update and delete stmts.
Ex:
>var a varchar2(20)
>var b number
>update emp set sal = sal + 3000 where empno = 7900
returning ename,sal into :a,:b;
>print a b

>delete from emp where empno = 7902
returning ename,sal into :a,:b;
>print a b
----------------------------------------------------------------------------
* Bulk Collect:
Used to return bulk data into pl/sql variables.
Variables must be of pl/sql table type only.
Improves performance while retrieving data.
Used with select, update, delete, Fetch stmts.

select ename,sal into a,b from emp where empno = &ecode;
ecode : 101

>declare
type names is table of emp.ename%type index by binary_integer;
type pays is table of emp.sal%type index by binary_integer;
n names; p pays;
begin
-- retrieving all employees in 1 transaction
select ename,sal bulk collect into n,p from emp;
-- printing table contents
dbms_output.put_line('EMPLOY DETAILS ARE :');
for i in 1 .. n.count loop
dbms_output.put_line(n(i)||' '||p(i));
end loop;
end;

* update emp set sal = sal + 3000 where deptno = 30
returning ename,sal bulk collect into n,p;

* delete from emp where job = 'CLERK'
returning ename,sal bulk collect into n,p;
----------------------------------------------------------------------------
Using in Fetch stmt :
declare
type names is table of emp.ename%type index by binary_integer;
type pays is table of emp.sal%type index by binary_integer;
n names; p pays;
cursor c1 is select ename,sal from emp;
begin
open c1;
fetch c1 bulk collect into n,p;
-- printing table contents
for i in 1 .. n.count loop
dbms_output.put_line(n(i)||' '||p(i));
end loop;
end;
----------------------------------------------------------------------------
Dynamic SQL:
Supports to execute " DDL" stmts in Pl/sql block.
syntax: execute immediate(' DDL stmt ');

>begin
execute immediate(' create table employ1
(ecode number(4), ename varchar2(20),sal number(10))');
end;

Note: Table cannot be manipulated in same pl/sql block

begin
execute immediate('drop table employ1');
end;

Clash of the Animal Titans

An incredible clash of Titans shows how a pregnant warthog desperately tries to defend herself - and her unborn baby - as a wild leopard savagely launches a stealth attack.

The explosive battle was caught on camera by British amateur photographer Mike Bailey as he holidayed in the remote Kwando River area of northern Botswana, Africa.

The spectacular dual between the huge spotted cat and the stouter tusked pig amazingly lasted over 10 minutes as the leopard tried to get the better of its prey.

Heart Attacks And Drinking Warm Water

A very good article which takes two minutes to read. I'm sending this to persons I care about.......I hope you do too!!! Heart Attacks And Drinking Warm Water This is a very good article. Not only about the warm water after your meal, but about Heart Attacks . The Chinese and Japanese drink hot tea with their meals, not cold water, maybe it is time we adopt their drinking habit while eating.

For those who like to drink cold water, this article is applicable to you. It is feels nice to have a cup of cold drink after a meal. However, the cold water will solidify the oily stuff that you have just consumed. It will slow down the digestion. Once this 'sludge' reacts with the acid, it will break down and be absorbed by the intestine faster than the solid food. It will line the intestine. Very soon, this will turn into fats and lead to cancer . It is best to drink hot soup or warm water after a meal.

French fries and Burgers are the biggest enemy of heart health.
A coke after that gives more power to this demon.
Avoid them for your Heart's Health

Common Symptoms Of Heart Attack...

A serious note about heart attacks - You should know that not every heart attack symptom is going to be the left arm hurting .

Be aware of intense pain in the jaw line .

You may never have the first chest pain during the course of a heart attack.

Nausea and intense sweating are also common symptoms.

60% of people who have a heart attack while they are asleep do not wake up. Pain in the jaw can wake you from a sound sleep. Let's be careful and be aware. The more we know, the better chance we could survive.


A cardiologist says if everyone who reads this message sends it to 10 people, you can be sure that we'll save at least one life. Read this & Send to a friend. It could save a life... So, please be a true friend and send this article to all your friends you care about.
