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.

Does anyone know how much free space should be left available on a storage partition to allow for the optimum performance? In fact is there any performance benefit to allowing a certain amount of free space on a partition that is occupied by SQL data files?

Does anyone know of any documentation on the performance of partitionmerge/split? Does the merge or split of a partition cause any lockingon the partitioned table? If you were merging or splitting a largevolume of data rebalancing your partitioned table would youpotentially lock users out?

Hi everyone,
I use sql 2005. What is the best practice for dealing with large table (more than million rows)? Table Partition, View or other?
Can you please give some suggestions? It will be very helpful if you can post some references or examples.

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

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

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?

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

I would like to partition a table having only items posted in the last 24 hours in one filegroup and all others in another. 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?
Thanks

Hi,
I have a table with 52 million rows which resides on Primary file group in my database. Because of huge number of rows the performance has gone very down and I would like to break the table into parts.
Can anyone suggest me the steps for doing the same and the number of parts that should be made. It is named as Account_Transactions and contains information of Policies in an insurance database.

How can I make partitions on a table for a particular value and ranges together?
For example, for customer id 12345 i need a separate partition, then for 56789 i need a separate partition, and if i have range of values like 1000 to 1020 then a separate partition for this.
For certain ids i need unique partition, and for certain ids i need Ranges.
is it possible in SQL 2012?

Hai,
we have a Dell pe 6600 server running for our ERP Application databases. version of Sql server is 2000 with sp4. OS is windows 2000 with SP 4 .we were running out of space in server and we planned to upgrade the harddisks.
after upgradation, the Performance of the server is very slow. Even zipping of .bak files from one drive to other is slow (which is not related to database). In old setup (before upgradation ) , to zip .bak files (backup files of DB's)(tot Size : 90 GB) use to take 3hrs 40 mins. Now it is taking more than 10 Hrs. There are no errors found in Windows Event viewer and SQL Server.
we logged a call with Dell and finally, dell said that they could not find any errors in raid configuration or harddisks. all the firmware and bios versions are up todate. Application vendor is also saying that, the database is fully optimized. we could not find out the reason for the sluggish performance and we feel that this is something to do with hardware or with raid configuration.
From our analysis,any activity that requires a read or write activity from the harddik is slow.( but server vendor is saying that there is no problem in the hardware.)
Activities analysed (all at zero load on server)
1) backup thru SQL Server - 40 mins (old setup)
backup thru SQL Server - 2 hrs (New setup)
2) zipping of .bak files (from Raid 5 HDD to Raid 1 HDD)
old setup - 3 hrs 40 mins
New setup - 8 hrs 30 mins
3) all the schedulers (both windows and sql server) are dead slow.
4) Maintenance jobs for databases
old setup - 5 - 6 Hrs
New setup - 11 - 12 hrs
after analysing all the above activities ,we came to a conclusion that the problem may not be with sql server.
But we could not trace out the problem till now. since it is the production server we are not able to take downtime that easily. i have given the old set up and new setup configuration below.
Note: the server lies with the same configuration in both old set up and new setup.(only harddisks are upgraded.
Please help me to solve this issue
As of now, we have decided to start from the scrap once again. before that can i get some help ???
old set up:
Raid 1 - 32 x 2 - (two Partitions C and D )
C - OS , D - Batch Files
Raid 5 - 72 x 5 - (two Partitions E and F ) (1 harddisk - Hotspare - 4 hdd will be used for raid)
E - .MDF Files , F - .BAK Files (Backup of database files will be stored here temporarily before moving it to tapes)
Raid 1 - 32 x 2 - (two Partitions G and H )
G - .LDF Files , H - to store the zipped .bak files ( we have a windows sceduler which zip the .bak files in E drive and place the .zip files in H drive)
New Set up:
Raid 1 - 72 x 2 - (two Partitions C: and D )
C - OS , D - Batch Files
Raid 5 - 300 x 5 - (two Partitions E and F ) (1 harddisk - Hotspare)
E - .MDF Files , F - .BAK Files (Backup of database files will be stored here temporarily before moving it to tapes)
Raid 1 - 72 x 2 - (two Partitions G and H )
G - .LDF Files , H - to store the zipped .bak files ( we have a windows sceduler which zip the .bak files in E drive and place the .zip files in H drive)

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]

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 ?Â
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.
