Calculate disk space needed for INDEX

guruparanApr 8 2010 — edited Apr 8 2010
Hi,

How to calculate disk space needed for creating an INDEX? Please point me to resources where I can get detail.

For Example:
I need to create an non UNIQUE INDEX on the following columns, a rough size would do.

<PRE>
EVENT_DATE NOT NULL DATE
APPT_DATE_SLOT VARCHAR2(15)
EVENT_STATUS VARCHAR2(4)
</PRE>

The table has some 7,300,000 rows. Let me know how to calculate too.

All helps are greatly appreciated.

did you try right-click on the project name from Projects panel and Copy ... option?

If I were you, for "exploring different scenarios", I would just stick with creating a new class (copy the existing one if you like) and make modifications all in the same project (instead of cloning the entire project).

HTH.

Hi mNem,  Both of your suggestions are good.  I just wanted to create a replica, mess around and then drop it.  So the clone works just right for me.  Thanks for your quick thinking.
