Developers who come to Oracle with a background in procedural languages sometimes do not understand how efficient SQL's set oriented processing can be. This little demonstration should convince them: never use PL/SQL when SQL will do.

We all know that using SELECT * is bad programming. One reason is that you cannot control the order in which columns are returned. Well, you can in release 12c.

In this first my blog entry I wish to post the code for send an Email message from one sender to one receiver.
The code is the follow:
v_From VARCHAR2(80) := 'sender.mail.com';
v_Recipient VARCHAR2(80) := 'receiver.mail.com';
v_Subject VARCHAR2(80) := 'test subject';
v_Mail_Host VARCHAR2(30) := 'smtp.libero.it';
crlf VARCHAR2(2) := chr(13)||chr(10);
v_Mail_Conn := utl_smtp.Open_Connection(v_Mail_Host, 25);

AIX is like an Unix environment awesome original, same to HP-Unix, and, if you have a plan to install Oracle RAC, you need to pay attention. I note some tips in this article to help.
1. Checking Operating System Packages
# lslpp -l bos.adt.base bos.adt.lib bos.adt.libm bos.perf.libperfstat \
bos.perf.perfstat bos.perf.proctools rsct.basic.rte rsct.compat.clients.rte \
If not, install on AIX source by smity. It's easy, but remember, some packaged requires your IBM's account to download.
