T-SQL (SS2K8) :: Use Variable In ALTER / CREATE PARTITION SCHEME Command For Filegroup?
May 9, 2010
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?
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?
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 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 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 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'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?
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.
1. Group records according to docno column. 2. Records will sort in desc order. (According to date1 column) 3. In date1 column if more than one date is same than we ll consider the date2 column. EX: 2008-04-30 00:00:00is same here so sorting will happen based on Date2 column. So internal sorting should happen instead assigning random values. 4. Number column is the expected output column.
Is it possible to show the number of rows and the range for each partition in a table ?
This shows me the range but not the row count per partition
SELECT sprv.value AS [Value], sprv.boundary_id AS [ID] FROM sys.partition_functions AS spf INNER JOIN sys.partition_range_values sprv ON sprv.function_id=spf.function_id WHERE (spf.name=N'myDateRangePF') ORDER BY [ID] ASC
i am using a OLE DB Source in my dataflow component and want to select rows from the source based on the Name I enter during execution time. I have created two variables,
enterName - String packageLevel (will store the name I enter)
myVar - String packageLevel. (to store the query)
I am assigning this query to the myVar variable, "Select * from db.Users where (UsrName = " + @[User::enterName] + " )"
Now in the OLE Db source, I have selected as Sql Command from Variable, and I am getting the variable, enterName,. I select that and when I click on OK am getting this error.
Error at Data Flow Task [OLE DB Source [1]]: An OLE DB error has occurred. Error code: 0x80040E0C. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E0C Description: "Command text was not set for the command object.".
Can Someone guide me whr am going wrong?
myVar variable, i have set the ExecuteAsExpression Property to true too.
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
Hello everyone, I just started learning sql and I came across a slight problem. Assume I have a customer table composed of the following fields: Customer_Number,Sname,Street,City,Postcode,credit_lim,balance.
What I want to do is to drop the Street,city,and postcode fields and add the following: fax,email,and phone.
Is it possible to use the following command:
Alter table customer Drop column street,city,postcode
Or should I do as following:
Alter table customer Drop column street
Alter table customer Drop column city
Alter table customer Drop column postcode
And the same goes to adding the phone,fax,and email field. Thank You.
NB: I need to use the Alter command and nothing else
Hi,I'm trying to run the ALTER TABLE command using a dynamic string for thetable, like so:DECLARE @TableName CHARSET @TableName = 'Customers'ALTER TABLE @TableNameADD ...blahIs this possible? We know this works:ALTER TABLE Customers ADD ...blahIt looks like I need a way to convert the CHAR value to a literal or perhapseven a table ID?Thanks in advance,Paul
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?
I need to create a new partition on a Cube using T-SQL and I am not much aware of either the Cubes or the ActiveX script. I am writing a T-SQL script for creating this partition on a cube.
Select Case iMonth Case 1,2,3 sQuarter = "1" Case 4,5,6 sQuarter = "2" Case 7,8,9 sQuarter = "3" Case 10,11,12
Hi all, I am trying to do a very basic ALTER Command and am trying to change its DEFAULT value. Code below is what I currently have:
Code Snippet
ALTER TABLE Table_1
ALTER COLUMN TEST VARCHAR(1000) NULL DEFAULT 2
Thanks, Onam.
*UPDATE* I found this code but are there alternative methods? Additionally, if I was to update its DEFAULT value again how would I go about doing that? Do I first have to remove the CONSTRAINT and then run the command?
Code Snippet
ALTER TABLE Table_1 ADD CONSTRAINT DF_Albumns_Comment DEFAULT 2 FOR TEST
This is for SQL2k5. The database may be small or big, I don't know (it's going out to multiple customers). I'm wondering if in general it's considered "better" to create a single non-primary default filegroup and put all the objects there, or just leave everything in primary? In one training years back I got the impression that recovering the primary filegroup was important for certain restore operations, so it was always wise to separate them like this.
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 used the code below to move the Model database and Model log file to new SAN drive locations. After running the commands I stopped the SQL server and moved the physical files to the correct location. Now I am unable to start SQL server, I get error 17204 Could not open file:Access is denied
I think the problem maybe that for FILENAME new_path I put "J:SQL ServerMSSQL.1MSSQLData" but did not include model.mdf in the file path.
How do I correct the path now that SQL service won't start? I have included the log file below.
ALTER DATABASE database_name MODIFY FILE ( NAME = logical_name , FILENAME = 'new_path/os_file_name' )
