Value ordered NUSI - forum topic by Moutusi

 
Hi All,
I have some doubts on value ordered NUSI.
1.       Can we create a NUSI on a column that already has a Value-Ordered NUSI defined on the same column? In that case will it have different sub-tables?
2.       For below example EMP No is UPI and Joining Date is value ordered NUSI of EMP table.

EMP No

EMP Name

Joining Date

1

ABC

01-01-2012

2

XYZ

01-01-2012

3

MNV

01-02-2012

4

RST

01-05-2011

 Suppose it has 2 AMPs and in that case each AMP will get 2 rows. In that case how will we get the benefit of VO NUSI for below query,as for UPI EMP No 1,2,3 may be distributed in different AMPs?
SELECT * FROM EMP
WHERE JOINING DATE BETWEEN 01-01-2012 AND 01-03-2012;
