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

Existing Table Gets A New Partition

How do you alter the table to use the new partition (I know ALTER TABLE is in there but BOL doesn't give a valid example with the move option)? I can create the partition but I want to apply it to an existing table with no partition?

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

Is there a way that my partition function could contain something like "col1 >= dateadd(d,-1,getdate())" and have items move to the secondary filegroup as they age pst 24 hours?

Unable To Get The Performance Partition Table

Jan 11, 2007

I created two tables one is based on partition structure and one is non-partition structure.

File Groups= Jan,Feb.....Dec
Partition Functions='20060101','20060201'......'20061201'
I am using RIGHT Range in Partition function.
Then I defined partition scheme on partition function.

I have more than 7,00,000 data in my database.
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.

SQL Server 2014 :: Partition A Big Table Into Years?

I'm looking to partition a big table into years.

I have a big table with data going back to 2001.

I need to partition this into file groups each for the last 5 years, and the rest into its own file group

I was going to convert the inherent date time field into the format int(yyyymmdd) and partition on that field.

Is this an acceptable way to achieve this? Is there a better way to partition on date? [not time]

Transact SQL :: Dynamic Partition For Partitioning Table

Jul 31, 2015

I am new to Partitioning tables. My scenario is as listed below.

I am getting Monthly Transaction data on Every First Monday of the Month and I want to do partition for those data.

For Example: Let's say I will get my next monthly data on August 3rd 2015 which is First Monday of the month of August.

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.

How To Attach The Existing Table To New Partition Function/scheme?

May 26, 2008

Normally we create a new table for tabler partitioning, like:

Code Snippet
CREATE TABLE [dbo].[Sales]
(
[SalesID] [int] IDENTITY(1,1) NOT NULL,
[SalesDate] [datetime] NOT NULL,
[col_01] varchar(50) NULL,
[col_02] varchar(50) NULL,
..
) ON [ps_Sales](SalesDate)
GO

with

Code SnippetCREATE PARTITION SCHEME [ps_Sales]
AS
PARTITION PFN_Sales TO ([FG_20080501], [FG_20080516], [FG_20080601], [FG_20080616],
[FG_20080701], [FG_20080716], [FG_20080801], [FG_20080816],
[FG_20080901], [FG_20080916], [FG_20081001], [FG_20081016])

But what if I have [dbo].[Sales] existed in db, that have attached to [PRIMARY]?

Alter table?

or I need to create a temp table first?
