Insert Select on same partition: RELATIONAL() - DELETE GLOBAL INDEX

3056262Oct 22 2015 — edited Oct 22 2015

Hi all,

I found on v$sqlarea following statament:

insert /*+ RELATIONAL("TABLENAME") PARALLEL("TABLENAME", 1) APPEND NESTED_TABLE_SET_SETID NO_REF_CASCADE */

into "SCHEMA"."TABLENAME" partition ("DAY20151015")

(

select /*+ RELATIONAL("TABLENAME") PARALLEL("TABLENAME", 1) */

*

from "SCHEMA"."TABLENAME" partition ("DAY20151015")

)

delete global indexes

It is a query that reads and writes the same data on the same partition!!!!!

I think it is generated by Oracle, but I don't undestand what it does.

Can you give me some explanation or help about that query?

Thank a lot
