DUMMY!

A Thought(idea) like DUMMY on DUAL table (Oracle Database) ;)

A DUAL has one column, DUMMY, defined to be VARCHAR2(1), and contains one row with a value X.

SQL> desc dual

 

 Name                                                                    Null?    Type

 -----------------------------------------------------------------------------

 DUMMY                                                                            VARCHAR2(1)

We start a thought like "X"... 

SQL> select * from dual;

D

-

X

Anyway, We can make any thought(idea), and No limited;)

SQL> select 1 from dual;

         1

----------

         1

SQL> select sysdate from dual;

SYSDATE

---------

29-MAR-09

SQL> select 1 + 1 from dual;

       1+1

----------

         2

SQL> select 'New Idea' from dual;

'NEWIDEA

--------

New Idea

that show we have many thoughts, but start from dummy (on dual).

So, Anybody can make idea (thought), and do it.
