Index On Partition Table

Feb 1, 2008

Hi all,
My question is about Indexs on partition where I have a table with say 5 partitions and I want to create index on partitions and not on the whole table. The objective is that if i create a table level index on a partition table and eventually if I drop one of the partition or add another partition, what will happen to the index?
1) Do I need to re-create the index for the partion which are left after deleting one partition?
2) If a partition is added do I need re-create the index for the whole table or just create the index for that particular new partition?

Let me know if there is any white paper or code available. I have gone through the white paper published "SQL Server 2005" Partitioned Tables and Indexes Author: Kimberly L. Tripp, Founder, SQLskills.com

Partition View And Index

Jan 28, 2004

I have created a horizontal partition view from 4 physical tables.
just wondering how the index works in the partition view:
1) If I need to build an index on a column, do I need to build
it on all 4 physical tables? or I just build it on the view? or build
it on view and 4 physical tables?

2) If I build it on view, and if I add a table into view, do I need to
recreate all indices on the view?

Partition Switch And Non Unique Index

Aug 9, 2006

'ALTER TABLE SWITCH' statement failed. The table 'dbo.test' is
partitioned while index 'IX_test' is not partitioned."

Any help?

ALTER TABLE SWITCH PARTITION On A Replicated Table

Apr 10, 2007

A customer wants to implement table partitioning on a replicated table.

They want to hold 13 months of data in the table and roll off the earliest/oldest month to an identical archive table. The table has a date field and partitioning by month makes sense all around.

So SWITCH PARTITION is the obvious solution to this, except for the fact that the table is replicated (transactional w/no subscriber updates).

What are his architectural or practical solutions to using table partitioning and replication?

thx

Partition Table

Feb 27, 2008

All,

I have a partitioned table (1.7 billion rows) that is across 97 partions. The table is partitioned on datetime field.

When I query only this table with datetime field in where clause I see that cleary it outperforms the unpartitioned table.

When this table is joined to 3 tables it performs no better than
the non-partitioned table... it seems that the query does a partition scan.

The part. table has a 3 part composite clustered index and
a NC index on the partion field value.

Would appreciate any feedback.

thanks

For certain ids i need unique partition, and for certain ids i need Ranges.

File Groups= Jan,Feb.....Dec
Partition Functions='20060101','20060201'......'20061201'

I checked filegroups and count rows. It works fine.

But When I check the estimation plan time out for query it is same for both partition table and non partition table.

The Index Entry For Row ID Was Not Found In Index ID 3, Of Table 357576312

Jul 9, 2004

Hi,

I'm running a merge replication on a sql2k machine to 6 sql2k subscribers.
Since a few day's only one of the merge agents fail's with the following error:

The merge process could not retrieve generation information at the 'Subscriber'.
The index entry for row ID was not found in index ID 3, of table 357576312, in database 'PBB006'.

All DBCC CHECKDB command's return 0 errors :confused:
I'm not sure if the table that's referred to in the message is on the distribution side or the subscribers side? A select * from sysobjects where id=357576312 gives different results on both sides . .

Any ideas as to what is causing this error?

Advantages Of Using Nonclustered Index After Using Clustered Index On One Table

Jul 3, 2006

Hi everyone,
When we create a clustered index firstly, and then is it advantageous to create another index which is nonclustered ??
In my opinion, yes it is. Because, since we use clustered index first, our rows are sorted and so while using nonclustered index on this data file, finding adress of the record on this sorted data is really easier than finding adress of the record on unsorted data, is not it ??

Thanks

I want those Transaction data to go in new partitioned FileGroup in my existing partitioned table. How can I do partition for this kind of scenario ? Can we create one or multiple Stored Procedure which will create New Partition and load data in that partition ?

FYI, this monthly data will be loaded in Staging table and that table has LoadDate column which will have 2015-08-03 in it. I am using SQL 2012 Enterprise edition.
