partition with single file group or multiple file group which one best.
we have some report running from partition table, few reports don't have any partition Key and after creating 400 partition with 400 file group it is slow.what is best practices to crate 400 file group or single file group.
Am I correct in assuming, in partitioning scenarion - the NUMBER OF PARAMETERS in a partitioning function is equal to number of file groups?

Why shrinkfile empty file does not redistribute data evenly in the primary file group with multiple files:
Please run the script attached to see what the end result is.
This is what I set up last night on my test machine.
1) Create database [FGTest] size 200MB
2) Create table called TEST on primary
3) Insert 40MB of data into test
4) Create another file group called temp in primary size 200MB
5) Shrinkfile('FGTest',emptyfile) so that all data is transfered from FGTest into temp file group.
6) Add another 2 files called DATA2 and DATA3. Both are 200MB.
7) We now have 3 empty files that I want data distributed evenly on. FGTest, DATA2 & DATA3
8) Shrinkfile('temp',emptyfile) to move all the data from temp over the 3 file groups evenly
I would expect at this stage to have the following:
FGTest = 13MB,
DATA2 = 13MB,
DATA3 = 13MB
(40MB of data over 3 files should be about 13 MBish in each file)
What I actually end up with is this:
FGTest = 20MB
DATA1 = 10MB
DATA2 = 10MB
It looks as though SQL Server is allocating 50% of all data to the original file and then 50% evenly over
the remaining files in PRIMARY.
I have a database around 500 GB. right now the database have only one data file and one log, it has only one filegroup also.all the indexes and table are placed in Primary Filegroup . we are going to separate them. the planing is to move all the indexes to Secondary filegroup and all the table will be in Primary filegroup.But there will be a problem while implementing it because there are around 600 tables and each table have at least 2 non-clustered index , so is there any way to move all the index to Secondary Filegroup.

A little background on what I am trying to achieve first. We are moving to Azure virtual machines and we will have 8 disks on the SQL Server box. I am adding more files to the primary file group and each file will go on its own drive. I am then rebalancing data across these files by rebuilding all of the indexes on the tables which is working fine. No problems so far all is good.
I now have an additional problem. If there is a lob or blob column on the table, rebuilding the clustered index and all the non clustered indexes doesn't rebalance the blob or lob data across the disks such as it does with in row data.
I cannot find any articles on rebalancing lob or blob data because all the articles say to move to a new file group. I do not want a new file group, I just want to use the primary file group where the data already resides, and just redistribute it evenly in the same way that I can in row data which is working fine.
One solution I thought about was to BCP data out of the table, truncate the table and then BCP back into the table which I imagine would have the desired effect of distributing the data evenly over the files.
For a database, we have 4 data files in a particular file group and the file sizes are almost 70 GB each.
Do I come across any performance issues if I create/pre-allocate an additional data file in the same file group so that the existing files don't grow too much?
In a server we had File Growth,And then We had to Add New Hard Drive And New File On It.And Now We have New server with a Huge Hard Drive.But all files remaind.Can I Reduce This files to One data file or not ?

I've 2 tables QuestionAnswers and ConditionalQuestions and fetching data from them using CTE join and I'm seeing repetitive rows (not duplicate) like, If you have multiple answers for 1 question, the output is like

I want to eliminate the repetitive question and group them as parent child items.

I have a table which has about 10 million rows, is it possible to
create a seperate file group just for that table?

I would like to set each cpu available per each file group.
How can I do?

If I have the first two columns from a SQL query and would like to create the third (row):
personid new_commsstream row
1 0 1
1 0 1
1 0 1
1 1 2
1 0 2
2 0 1
3 0 1
4 0 1
5 0 1
5 1 2
5 1 3
Is this possible? I have tried using row over partition but I'm not sure how group it correctly, so basically every time there is a new 1 in new_commsstream within a personid the row number goes up by one.
I have an SSRS 2012 table report with groups; each group is broken ie. one group for one page, and there are multiple groups in multiple pages.
'GroupName' column has multiple values - X,Y,Z,......
I need to group 'GroupName' with X,Y,Z,..... ie value X in page 1,value Y in page 2, value Z in page 3...
Now, I need to display another column (ABC) in this table report (outside the group column 'GroupName'); this outside column itself is another column header (not a group header) in the table (report) and it derives its name partly from the 'GroupName' values:
Example:
Value X for GroupName in page 1 will mean, in page 1, column Name of ABC column must be ABC-X Value Y for GroupName in page 2 will mean, in page 2, column Name of ABC column must be ABC-Y Value Z for GroupName in page 3 will mean, in page 3, column Name of
ABC column must be ABC-Z
ie the column name of ABC (Clm ABC) must be dynamic as per the GroupName values (X,Y,Z....)
Page1:
GroupName Clm ABC-X
X
Page2:
GroupName Clm ABC-Y
Y
Page3:
GroupName Clm ABC-Z
Z
I have been able to use First(ReportItems!GroupName.Value) in the Page Header to get GroupNames displayed in each page; I get X in page 1, Y in page 2, Z in page 3.....
However, when I use ReportItems (that refers to a group name) in the Report Body outside the group,
I get the following error:
Report item expressions can only refer to other report items within the same grouping scope or a containing grouping scope
I need to get the X, Y, Z ... in each page for the column ABC.
I have been able to use this - First(Fields!GroupName.Value); however, I get ABC-X, ABC-X, ABC-X in each of the pages for the ABC column, instead of ABC-X in page 1, ABC-Y in page 2, ABC-Z in page 3, ...

Weird. I have an Agent job that populates some warehouse data every night. It's been working fine for over a year. Then it fails with a message that thePRIMARY file group is full. The database is set to Simple recovery, automatic, unrestricted growth by 10% for both the log file and the data file. The drive it's on has 96GB free. The data file is 1.5GB and the log is 2MB and there's not very much fluctuation in the amoutn of data going into it.
Anybody have an idea why that would happen?
Thanks for any insight,Pete

Hi all
I have a table called ACTIVATION_CONSUMPTION which is in PRIMARY file group, in order to move this table to new file group [FG_ACTV], I have done the following
1. ALTER DATABASE [MYDB] ADD FILEGROUP [FG_ACTV] (i have not attached a file to this file group)
2. IF EXISTS (SELECT * FROM sys.indexes WHERE object_id = OBJECT_ID(N'[dbo].[ACTIVATION_CONSUMPTION]') AND name = N'ACTIVATION_CONSUMPTION_PK')
ALTER TABLE [dbo].[ACTIVATION_CONSUMPTION] DROP CONSTRAINT [ACTIVATION_CONSUMPTION_PK]
GO
3.ALTER TABLE [dbo].[ACTIVATION_CONSUMPTION] ADD CONSTRAINT [ACTIVATION_CONSUMPTION_PK] PRIMARY KEY CLUSTERED
(
[ACTIVATION_CONSUMPTION_ID] ASC
)WITH (PAD_INDEX = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF) ON [FG_ACTV]
The above command executed successfully and now the table is in new file group [FG_ACTV]
My question is how come the table was moved to new file group though it has no files attached to it?
Thanks in advance.
