I had a table which is going to burst, and of course performance issue is come in to place. and now we thinking to apply to partition method into this table.
So is that possible to create a partition scheme and against the existing table? and how is the T-SQL statement will be look like.
How to add some more ranges to existing partition schema and function?
Already My table partitioned on date ranges,
6 partitions , each partition contains 6 moths data, so total data is 3 years.
i.e. 1 partition data- from jan2012 to Jun2012 2 partition data- from july2012 to dec2012 3 partition data- from jan2013 to Jun2013 4 partition data- from july2013 to dec2013 5 partition data- from jan2014 to Jun2014 6 partition data- from july2014 to dec2014 After Jan2015 data will go to Primary file group(Default)
Now customer wants to add two more file groups with these partitions ranges, i.e. jan2015 to jun15 and Jul15 to dec15.
File group and ndf file adding is OK, But
how to alter partition scheme and partition function with these additional ranges to existing partition function and scheme?
Is it possible to use a variable to specify the filegroup in the ALTER/CREATE PARTITION SCHEME command?
I want the partition scheme to use the default filegroup for ALTER and CREATE PARTITION SCHEME. At the time the script is created, I don't know the default filegroup in the database.
My code:
declare @fileGroupName VARCHAR(50) = (select top 1 name from sys.filegroups where is_default = 1) ALTER PARTITION SCHEME MyScheme NEXT USED @fileGroupName
Is failing:
Incorrect syntax near '@fileGroupName'.
Q: Is it possible to use a variable for the filegroup in the ALTER/CREATE commands? Is so, what is the correct syntax?
Q: If using a variable is not possible, is there another way to specify the default filegroup?
I have a non-partitioned table (TableToPartition) and I want to apply an existing partition scheme (PartSch) to it using a query. I didn't find any option so I used the StorageCreate Partition wizard to generate the script.why this clustering magic needed if it is dropped at the end? Isn't there another way without indexing to partition a table, say something with ALTER TABLE? (SQL Server 2012)
BEGIN TRANSACTION CREATE CLUSTERED INDEX [ClusteredIndex_on_PartSch_635694324610495157] ON [dbo].[TableToPartition] ( [ID] )WITH (SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF) ON [PartSch]([ID]) DROP INDEX [ClusteredIndex_on_PartSch_635694324610495157] ON [dbo].[TableToPartition] COMMIT TRANSACTION
I've having some baffling problems with a java applicaiton!
I have an application server called WA01 which used to access two tables on an MS SQL 2000 server via a scheme login. The two tables are:
_PurchaseOrderInterface _PurchaseInvoiceInterface
Both tables were owned by the scheme user, with enough permissions to read & write. The java application on server WA01 could happily read the data within the tables and write a bit flag back to each row.
The MS database has been moved to a new server which no longer allows the java application on server WA01 to access the tables via the scheme login, the only way the java app can view and update the tables is by changing the owner of the tables to dbo. The new server is still MS SQL 2000, with comparible security settings.
The java app keeps complaing of an unknown source when trying to access via scheme, is this a domain trust issue between the two servers? Any ideas would be welcomed. I'm not an SQL expert but have a good grasp of the security structure etc.
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?
I am facing issue in generating total sum and daily sum from table ThresholdData.
DailyTransactionAmount should be sum of todays amount in the table TransactionAmount should be sum of all amount in the table.
Basically,
1. I don't want to scan ThresholdData table twice. 2. I don't want to create temporary table/table variable/CTE for this. 3. Is there is any way to make it done in single query.
I hope, where criteria is not possible in partition function. I am trying query something as given below,
SELECT  TransactionDate,   TransactionAmount,   ROW_NUMBER() over (order by TransactionDate) AS TransactionCount,   SUM(TransactionAmount) over (partition by id ) AS TransactionAmount,   SUM(TransactionAmount) over (partition by id ,CONVERT (DATE, @TodaysTransactionDate)) AS DailyTransactionAmount  FROM ThresholdData  WHERE id = @id  AND transactiondate >= dateadd(d,-@TransactionDaysLimit,@TodaysTransactionDate)
Hi,I need to create a partition table but the column on which I need tocreate a partition may not have any logical ranges. So while creatingor defining partition function I can not use any range.likeCREATE PARTITION FUNCTION my_part_func (NUMERIC(7)) AS RANGE LEFT FORVALUES (1,100,1000);Is there any way to define partition function in SQL Server somethinglike Oracle HASH partitions where logical range is unkown?ThanksSameer
DECLARE @DatePartitionFunction nvarchar(max) = N'CREATE PARTITION FUNCTION DatePartitionFunction (datetime) AS RANGE RIGHT FOR VALUES ('; DECLARE @i datetime = '2007-09-01 00:00:00.000'; WHILE @i < '2008-10-01 00:00:00.000' BEGIN SET @DatePartitionFunction += '''' + CAST(@i as nvarchar(10)) + '''' + N', ';
[Code] ....
Msg 7705, Level 16, State 2, Line 1 Could not implicitly convert range values type specified at ordinal 1 to partition function parameter type.
However if I change to datetime2 it works
DECLARE @DatePartitionFunction nvarchar(max) = N'CREATE PARTITION FUNCTION DatePartitionFunction (datetime2) AS RANGE RIGHT FOR VALUES ('; DECLARE @i datetime2 = '2007-09-01 00:00:00.000'; WHILE @i < '2008-10-01 00:00:00.000' BEGIN SET @DatePartitionFunction += '''' + CAST(@i as nvarchar(10)) + '''' + N', ';

Is the data type of the column used for partitioning. All data types are valid for use as partitioning columns, except text, ntext, image, xml, timestamp, varchar(max), nvarchar(max), varbinary(max), alias data types, or CLR user-defined data types.
In this case why isn't datetime works?

Table and index partitioning is supported in this edition
I have a heavy database , More than 100 GB only for six month .every Query on it takes me along time and I dont have enough space to add more indexes.by a way I decided to do partitioning. I create a partition function , on date filed and all Data records per month was appointed to a separate file.And is partitioning only for Future data entry?
I'm currently stuck with a table that has 350 mil records. Querying this table is insanely slow so I had a better look at existing yearly partitioning. I already managed to partition on a month level which increased the performance/querrying a lot. I did this on the staging table where I used an alter statement to split the 2015 partition by 12 months.
However, in our project we used Data Vault. This means that we have 4 tables (hub, sathub, link, satlink), all carrying 350 mil records. The problem is that altering the partition function does not work. The server cannot handle this action. What the best way is to do this, without having to drop/reload all tables.
I'm wondering if SSIS can capture the table schema structure, including the primary keys, foreign keys and indexes applied from the source table to the destination table? My source tables will be coming from AS400/DB2 and I'm using OLEDB Provider for DB2. I would like to automatically generate the table schema of my destination table in SQL Server 2005 (thru SSIS) as similar as my source table from AS400.
1) In which codeset OPENROWSET reads the datafile? Is there any way to specify to OPENROWSET to read in a specific format(i.e. as Unicode data or non-unicode data etc.)? 2) Can we specify datatype as "SQLCHAR" and collation type as "SQL_Latin1_General_CP1_CI_AS", in format file, for unicode characters? If this is wrong,what is the alternate for Unicode characters? 3) Is there any other place the problem can be?
I m using sql server 2005 i have got one request ,to apply page level locking on database can nyone how it is done i can do that for a single script and for session(transaction isolation level) but dont know about database level locking scheme
we're in a business where customers often ask for a foolproof scheme that even prevents folks with DB privileges from fraudulently inserting, updating or deleting data. The scheme must be so air tight that a judge can be convinced of its reliability.
Can someone take a look at my code and tell me what i'm doing in wrong. The script runs fine but when i go to table property it says the table is not partitioned. Thanks for your help.

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?
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?
Please help me how to do the Horizontal table partition?? I have to split the table in to multiple sub tables with same columns and less rows and then I have to use each sub table.
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 Active = 'Yes'
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.
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?
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?
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?
