How to create exact copy of a table
Hello,
I must admit my "google skills" have failed me and it is possible that I might be missing something obvious here but allow me to explain.
If I have a table that is populated/accessed by a typical OLTP application such that over time the data in the table may become "fragmented".
I know that is a very controversial term I used but that is not the question here. A simple way to describe the state of the table might be
that the table has always been populated with lots of small INSERTs, modified with lots of small UPDATEs and data has been deleted in small DELETEs.
This has meant that the data is neither closely stored in data blocks nor is in any particular order (so there are some empty blocks under HWM).
Now my question is how do I create exact copy of this table and its indexes AS THEY EXIST AT THE MOMENT that includes
1) its data
2) its constraints/indexes etc.
3) its storage parameters
4) data stored in EXACTLY same manner as in original table.
To avoid complications, the table in question is just a normal heap table without any partitioning involved. While CREATE TABLE AS SELECT (or CREATE
TABLE followed by INSERT) will take care of points (1) to (3) above, it will not achieve point (4) above.
Can somebody please help?
Thanks in advance.
