SQL 2012 :: How To Add New Filegroup To Existing Partition Scheme
Jul 10, 2014
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 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.
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 create a partition function and a partion scheme for my database. Now I would like to change an existing table to use these partition. The table is replicated. How can I do this?
I can't seem to find a way to do the following:create table part_table (col1 int,col2 datetime) on psX (datename(week,col2))I want to partition based on the week number of a date field.So if I enter in data like the following in my part_table:(1, 1/1/2007) should go into partition 1 for week #1(52, 12/21/2007) should go into partition 52 for week #52 of the yearI tried adding in a computed column, but it says its nondeterministic.
I have partitions that I have filled with data. I am not trying to figure out exactly how much data the partitions contain, and therefore I will be able to see if any of them are close to hitting their autogrow conditions. If I were looking at a single unpartitioned table, then I could maybe look at the table properties to determine data and index sizes, and compare that to the size of the mdf file size, but for partitions, then I am not sure how I would query this information out. Any pointers on how this information could be queried out of the system?
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 work for a 24/7 shop. We currently have a table that is partition on monthly. I have to created a script that will add a new file group, add the new file to the group, and alter the the partition scheme and function. However, I need for this process to not cause a lock on the table. Typically I get the locking and issues when I am run the split command. Is there a way to prevent this from happening?
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? Thanks
How to move existing table(include its constraint and index) into a different filegroup using tsql in Sql Server 2000. We have 1000+ tables in our system and we are planning to move around 500 tables to a new file group, which is available on another SAN drive.
Can we create the Partition on Existing Table?e.g Create table t ( col1 number(10,0), Col2 Varchar(10)) ;After the table Creation can we alter the table to partition the table.
I have 3 columns. I would like to update a table based on job_cd and permit_nbr column. if we have same job_cd and permit_nbr, reference number should be same else it should take max(reference number) from the table +1 for all rows where reference_nbr column is null
I have the following insert query which works great. The purpose of this query was to flatten out the Diagnosis codes (ex: SecDx1, SecDx2, etc.) [DX_Code field] in a table.
Code Snippet INSERT INTO reports.Cardiology_Age55_Gender_ACUTEMI_ICD9 SELECT Episode_Key, SecDX1 = [1], SecDX2 = [2], SecDX3 = [3], SecDX4 = [4], SecDX5 = [5], SecDX6 = [6], SecDX7 = [7], SecDX8 = [8], SecDX9 = [9], SecDX10 = [10], SecDX11 = [11], SecDX12 = [12], SecDX13 = [13], SecDX14 = [14], SecDX15 = [15] FROM (SELECT Episode_Key, DX_Key, ROW_NUMBER() OVER ( PARTITION BY Episode_Key ORDER BY DX_Key ) AS 'RowNumber', DX_Code FROM srm.cdmab_dx_other WHERE Episode_key is not null ) data PIVOT ( max( DX_Code ) FOR RowNumber IN ( [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15] )) pvt ORDER BY Episode_Key
The query below also works fine by itself. You may notice that the Episode_Key field appears in both the query above and below therefore providing a primary key / foreign key relationship. The srm.cdmab_dx_other table also appears in both queries. I would like to add the fields in the select statement below to the select statement above. Using the relationships in my FROM statements, can anyone help me figure this one out?
Code Snippet SELECT e.episode_key, e.medrec_no, e.account_number, Isnull(ltrim(rtrim(p.patient_lname)) + ', ' ,'') + Isnull(ltrim(rtrim(p.patient_fname)) + ' ' ,'') + Isnull(ltrim(rtrim(p.patient_mname)) + ' ','') + Isnull(ltrim(rtrim(p.patient_sname)), '') AS PatientName, CONVERT(CHAR(50), e.admission_date, 112) as Admit_Date, CONVERT(CHAR(50), e.episode_date, 112) as Disch_Date, e.episode_type as VisitTypeCode, d.VisitTypeName, convert(int, pm.PatientAge) as PatientAge, pm.PatientAgeGroup, pm.patientsex, p.race FROM srm.episodes e inner join srm.cdmab_dx_other dxo on dxo.episode_key=e.episode_key inner join srm.cdmab_base_info cbi on cbi.episode_key=e.episode_key inner join srm.item_header ih on ih.item_key = e.episode_key inner join srm.patients p on p.patient_key = ih.logical_parent_key inner join ampfm.dct_VisitType d on d.VisitTypeCode=e.episode_type inner join dbo.PtMstr pm on pm.AccountNumber = e.Account_Number
My intention is to make a copy of a database with some data excluded. One way to do this:
- Make a copy-only backup of the source database - Restore the backup as a new database - Delete undesired data from the new database
In my case, the source database has two file groups, primary and secondary. The secondary has just one table with huge amount of data and this file group appears as one physical file. Is there any way to make a partial backup, which does not include this file group or table, and it would still be possible to restore the backup to a new database? My point is to avoid copying huge amount of data if it won't be needed.
I must determine FILEGROUP on my DB in SQL Server. Because when i wants to retrieve files which is stored in db, it would be face with error about FILEGROUP.

I have one stored proc that uses the Row_number over partition that looks like this:
Select TargetID, Academic_Year_id, Course_Mode, UK_Enrol, Int_Enrol, Notes, Revision_Number from (SELECT ROW_NUMBER() OVER (partition by [Academic_Year_id] order by [Revision_Number] DESC) as [RevNum],TargetID, Academic_Year_id, Course_Mode, Target_Year, UK_Enrol, Int_Enrol, Notes, Revision_Number FROM tbl_targets where course_mode=@course_mode) RV where (RV.RevNum=1)
Now the next store proc needs to use the above but i need to add the Academic_year from the tbl_acyear_lookup table also add filter the target_year ='year 1'
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.
I am looking at the file / filegroup level backup and recovery options within SQL Server and I'm struggling with the following concept.
Books online assures me that it is possible to perform a file restore whilst the database is in the simple recovery model.
So I have set up a database with two separate file groups, a read/write primary and a read only "secondary". Each filegroup has 2 underlying data files.
I have then created a "live" customers tables within the primary filegroup and assigned my existing "archive" customers tables within the secondary filegroup.
If I try to perform a file or filegroup level backup within management studio, those options are greyed out. I can only perform a database backup.
If I switch back to the full recovery model, the options are no longer greyed out.
So my question is this, is file level backup and recovery actually supported in the simple user model, do you have to perform this task outside of management studio, or (as is likely) am I missing something crucial?
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', ';
[Code] ...
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’m looking for clearity on partition switching. The idea is to use many BULK INSERT statements into table dbo.X_n in parallel and when BULK INSERT for table dbo.X_n is completed, switch dbo.X_n into dbo.bigdaddy. I think this is the fastest way to upload a couple hundred GB of data.
In learning about partition switching (in part) from The Data Loading Performance Guide under Partition SWITCH, I hear the instructions to say copy the main table exactly to become a target. But in that same step (#1), I read that we need to change the default file group of the target (dbo.X_n) from the default file group. Then it says I need to match indexes and lists the filegroup as something we need to match with the main table.
As an overview of the partition switching strategy, I think the whole point of BULK INSERT with partitioning is to have seperate files (in same group) to enable concurrent uploading where each table has its own file. Once the upload is completed to a table (dbo.X_n) then we do the partition switch into the main table (dbo.bigdaddy). The data we just uploaded doesn’t actually move, just the metadata for it.
“Don’t have the same filegroup on your target as the main table. You must have the same filegroup on your target as the main table.”
I have a table. I want to add 2 date columns. One when we are inserting any record it will show and another whenever the record updated to record that.
I want to insert dummy data for the previous dates. How to insert those dummy dates in batch wise?
I have a SQL 2012 enterprise server, and I'm using Commvault as my backups. So commvault can restore a .bak file to my server, but it cannot use sql compression on the file apparently. So what would be a 150GB .bak backup file is now 600GB. I have to manually upload these files to an auditing firm on an sftp server and the transfer times are now huge.
Is there a way to use something in sql to compress this already existing .bak file down?
