Partition Tables In Sql 2005
May 15, 2008
Hello ,
I am trying to implement paritioned tables in SQL 2005. So far, I am successfull implementing partioned tables
using filegroups. I have created three filegroups and partitioning table in those three file groups using PARTITION FUNCTION,PARTITION SCHEME and I am successfully partitioned table on my local machine .
But now I need to implement a partitioned tables residing on multiple machines. Would anyone help me for this topic?
I am using filegroups to partitioning table. Is there any way to partition tables across multiple database servers
without using filegroups?
Thanks
Rohit

Hi,
Is there any way to configure SQL 2005 install to go into a separate partition likeDrive E:? I want all the program files, system files, dlls etc to go into Drive E.
This is what I know - I know that some SQL system files will install be default on drive c. Am correct on this?
Thanks,

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?

I created two partitions for my hard drive. The C drive which holds all of the Windows 2003 server operating system files and E drive which will be just for data and applications. The C drive is only 30GB while the E drive is 119GB. I need to be able to install in the application on the E drive. I already tried creating a folder on the E partition named program files with the sql2005 folder in it when I go through the installer package. SQL server still wants to be installed on the C drive. Is there anyway I can change this so it gets installed on the E partition. Thank You

I want to find a way to get partition info for all the tables in all the databases for a server. Showing database name, table name, schema name, partition by (maybe; year, month, day, number, alpha), column used in partition, current active partition, last partition (for date partitions I want to know if the partition goes untill 2007, so I can add 2008)
all I've come up with so far is:
Code Block
SELECT distinct o.name From sys.partitions p
inner join sys.objects o on (o.object_id = p.object_id)
where o.type_desc = 'USER_TABLE'
and p.partition_number > 1

I'm new to my company, although not new to SQL 2005 and I found something interesting. I don't have an ERD yet, and so I was asking a co-worker what table some data was in, they told me a table that is NOT in SQL Server 2005's list of tables, views or synonyms.
I thought that was strange, and so I searched over and over again and still I couldn't find it. Then I did a select statement the table that Access thinks exists and SQL Server does not show and to my shock, the select statement pulled in data!
So how did this happen? How can I find the object in SSMS folder listing of tables/views or whatever and what am I overlooking?
Thanks,
Keith

I've tried creating a simple SSIS package but I get the error:
[Transfer SQL Server Objects Task] Error: Execution failed with the following error: "Cannot apply value null to property Login: Value cannot be null..".
THis is a known bug and while we wait for SP1 to fix this error, is there another way to simply copy tables (with indexes and without having the identity column renumbered) ?
Any help is appreciated!

i have a table named table1 sitting on a a partittion scheme px.
table1 is partitioned on u_id by tens,
first partion u_id=0 to 9
second partion u_id=10 to 19
third partion u_id=20 to 29
ans so on and so forth
i have a table named table2 with
records having u_id = 13 to 16
obviously belonging to the second partion.
i want to load table2 to table1 as fast as i could with
the following requirements:
all contents of partition 2 of table1 must be deleted before loading
table2 ceases to exist after the operation
how will i do that.
thanks.

I can see lot of documentation on Range Partitioning. Is there any other type of partition supported in SQL Server 2005?
For example, I have a Fact table having Billion rows. It has a column called BATCH_ID. A BATCH_ID corresponds to 10-20 Million rows and it is a running sequence number like 1,2,3 etc. (not an identity column). Is there anyway I can specify a partition function with BATCH_ID column as an int value? Will the SQL Server automatically does the partition on each int value in that case? If not, what is the best way to do it?
Thanks in advance for all help in this

Hi,
I recently installed MSSQL 2000 and sp3a onto a windows 2003 server in a test lab. I configured one big c: partion on this os and installed the db in the default location.
I need to detach the db's on this server and re-attach them onto another MSSQL 2000/sp3a server running 2003 os with a partition scheme like this:
c: = 20 gigs for the os
e: = 600 gigs for the data
I could not re-attach the db's onto the e:default path odatabase
Is there a work-around for this? This makes sense to me as to why it is not working and was an install oversight on my part but there has to be a way to overcome this delima?
Thanks in advance,
damnit

I keep getting this error:
Msg 156, Level 15, State 1, Line 12
Incorrect syntax near the keyword 'over'.
What am I missing? The max() over statement looks just like the statement in the documentation.
select RegistrationId,
OrderId,
Sequence,
Title,
InformalFirstName,
FirstName,
MiddleName,
Lastname,
EntryDate,
max(Sequence) over(partition by RegistrationId) as 'maxsequence'
from registration
where OrderId = '68379449583' and
Year = '2008' and

I have a situation where my SQL works everywhere else but my COBOL compiler complains wherever I use PARTITION BY. I can't find a workaround for that problem so I would like to remove all the PARTITION BYs. I'm not confident that I can do this accurately and would like some help getting started.
Here is my simplest example:
SELECT FESOR.REGION, FESOR.TYPE,
COUNT(*) OVER (PARTITION BY FESOR.REGION, FESOR.TYPE)
FROM FESOR, FR
where FESOR.phase = 'Ref'
and FESOR.assign is null
and FESOR.comp_date is null
and FESOR.region = FR.REGION
and FESOR.type = FR.TYPE
and FR.REP_ROW='A'
GROUP BY FESOR.REGION, FESOR.TYPE
What I'm looking for is a modified version of the SQL above which returns the same result set without using PARTITION BY.
Thanks in advance for your assistance.

Guys,
I have names in the database which I want partition by last name - for example last names starting with A, B, C, D should go to the file group 1. last names starting with E, F, G, H should go to file group 2.
I am trying to use the following function - but do I specify in the function that last names with with A, B, C, D should go to the file group 1
CREATE PARTITION FUNCTION myRangePF3 (char(20))
AS RANGE RIGHT FOR VALUES ('EX', 'RXE', 'XR');
Is there any way to modify partition function to accomplish this?
Any suggestions and inputs would help
Thanks

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

HI all,
I am in the progress of migrating my 2000 install over to SQL05 and onto a couple of new boxes. I have 2 Dell 1850's to set up mirroring on and wanted to know your opinion on the best partition setup. The 1850's are a 2 disk machine so it has to be a RAID 1 setup. I am just unsure of the benefit of partitioning the logical drive to seperate the log files from the data files.
Should I partition the drive, a 300G SCSI into 2 partitions and keep the logs on one partition and the data on another? Can anyone tell me if there is a benefit to doing this?
If there is a more pratical solution can you explain?
Thanks in advance!

Most examples for SQL Server 2005 involve a sales table that you split based on date, i.e. sales records prior to 2000 go to this partition, and the ones after that go to another one. Nice and simple.
Say I have a sales table:
id Amount Date
1 10 1/1/1999
2 9.99 1/1/2007
Now then, I put all the records prior to 2000 in it's own partition.
So when I do something like this: SELECT * FROM Sales WHERE DATE = 1/1/1999
the SQL server will know which partition to look at. Very nice.
Now then, if I do this: SELECT * FROM Sales WHERE id = 1
How will the SQL server know which partition to look at?
Thank You!

hi list
i have a table named stgBudgetFact, that is partitioned on DivisionID.
each DivisionID goes into its own partition, which is on its own file group.
the etl guru on the project wants to be able to truncate the partition, not do a delete from the table based on DivisionID.
Is it possible to truncate the partition somehow (remove rows where DivisionID = 3 for instance without ALTER DATABASE, where the medicine is worse than the disease) and then reestablish the partition so we can restart a failed load by division?
i really hope something like this is possible
thanks

Dear all,
Sorry if my post misplaced. I have a table that contain huge data so I made a partition function and partition schema. Unfortunately there's only one column to be allowed as a partition column whereas my queries using a few columns. Can we make many partition function that apply to one partition schema ? I search no result in SQL BOL.
Thanks in advance.
Best regards,

How complex can the over (partition by...) window functions be? All the examples I see in BoL, the partition clause is the same for each window function. Can it be different? How different?
Here are some snippets of where I'd like to take this. Right now I'm using successive views to bring the results to a single row.
SUM(building_function_table.e_and_g_square_foot + building_function_table.auxillary_square_foot)
OVER (PARTITION BY building_function_table.fice_code, building_function_table.building_number) AS sqft
SUM(building_function_table.e_and_g_square_foot * function_table.square_foot_value)
OVER (PARTITION BY building_function_table.fice_code, building_function_table.building_number,building_function_table.function_code) AS repl_value_e_g
SUM(building_needs_table.percentage * (building_needs_table.age / system_component_table.useful_life) * component_multiplier_table.multiplier)
OVER (PARTITION BY building_needs_table.fice_code, building_needs_table.building_number, building_needs_table.system_code, building_needs_table.system_component_code, building_needs_table.function_code) as maint_needs
And it gets even more complex, but these are all I've written because I don't know if it will work.
These would be all part of a giant overhead view of a building maintenance database. It's normalized and the respective tables above are all simple inner joins on the primary key of their parent.

I have the pagefile.sys on the same partition (C:)as the database files. I been advised this is not a good idea. I'm getting paging. I'd like to move the swapfile to another partition on the same drive. Is that a good idea, or should I move it to another physical disk? And is it OK to leave the OS partition (C:) without any swapfile? Thanks!!
