SQL Server Admin 2014 :: Adding New Partition To Filegroup
Nov 28, 2014
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?

we have many max fields in our database .
A role in performance says : It's better to separate this fields to another FileGroup with separate file.
Is the result good for performance? and what are the risks?

I'm being asked to create multiple filegroups for a new database based on the table type, transaction, lookup, misc... From what i'm reading this doesn't make sense. I'm reading either large tables get file groups, nonclustered indexes when they are about the same size of the data, or a few other reasons...
First of all, we are talking about the same disk (please don't ask me about how it is configured) and I'm not sure yet if restoring separate file groups is even going to be necessary.
So here are my questions (beyond, the test and see what happens) because in the end I'm going to probably have to do what i'm told. So this is for my professional knowledge.
1. Does file groups separated by table type make sense?
2. Should you put tables that are queried often together in the same or different file groups.
3. I'm pretty sure you can't restore single file group for write access, am I correct?

How do i find Total allocated space and used space of a memory optimized filegroup?
use memory_optimized_db
Go
select (SUM(size)*8.0)/1024.0 as Space,
FILEGROUP_NAME ( data_space_id ) , type_desc from sys.database_files
group by data_space_id,type_desc;
above query gives "current used size of the container " of memory optimized file group but doesn't give Total space detail.

I need to modify a table to reside on a new filegroup and also point TEXTIMAGE_ON to that filegroup instead of PRIMARY. Apparently in the past, the only way to achieve this via SQL is to create a new table, copy over data, drop the old table and rename the new table to the original name. I found this solution in the SQL Server 2005 forum.
Is there any other way to alter this table in order to point the TEXTIMAGE_ON to new filegroup using SQL Server 2014? We are on Standard edition. The technique I am using is the drop constraint (with move option) and add constraint (to new filegroup) commands. The data and indexes move, but not the text data (it still is in primary filegroup).

I have been creating databases in SQL 2008 with a primary filegroup for the system objects and a secondary, marked Default, for the data.
We are preparing a migration to SQL 2014, and the administrator is complaining he won't adopt this structure on the new servers because 'there is no benefit' and 'a backup cannot be restored (!?)'.

I read , When sql server Database having multiple data files within single filegroup then sql server writes data in multiple proportional file algorithm where the amount of data written to a file is proportionate to the amount of free space in that file, compared to other files in the filegroup.
so if there is no filegroups created and multiple secondary files are attached in databse , is there same way data stored and writes data in multiple files by the same algorithm or any different way.

We have a server A and a server B setup with SQL2014 High Availability - working fine.
I need to add an additional listener to our new DR site.
What is the best way to do this without impacting production - can I just add the additional replica from nodea as a secondary replica?

I want to set up a database role so that users can use sp_readerrorlog through SSMS. It does a check on membership in the securityadmin role.
I have tested it and can see you can grant execute on xp_readerrorlog but the SSMS GUI uses sp_readerrorlog.
I thought I could create a user/certificate and add the signature to sp_readerrorlog but it's not permitted (likely because it's not a normal database object).
So the other solution is to add the users to the securityadmin role but then explicitly deny alter any login (best done with a custom server role in 2012+ but otherwise just manually in 2008). I tested this out and it works, I'm not able to alter any logins or increase my own permissions, I also did a check of what's reported from fn_my_permissions(null, null) and it shows minimal permissions like I'd expect.

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'm looking to partition a big table into years.
I have a big table with data going back to 2001.
I need to partition this into file groups each for the last 5 years, and the rest into its own file group
I was going to convert the inherent date time field into the format int(yyyymmdd) and partition on that field.
Is this an acceptable way to achieve this? Is there a better way to partition on date? [not time]

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?
partitioned table size is 200 GB.

I read this: [URL] ....
Which says you must drop the database to remove the filegroup.
I deleted all the objects and then backed up the DB and restored it and the filegroup is still there.
I was skeptical but some of the comments made me think this might work.
Do I really have to restore from a pre-memory optimized state?

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 want to use BCP to load data from a text file.
By default, constraints are turned off in bcp, so I use the CHECK_CONSTRAINTS hint.
bcp aborts if ANY of the rows contains a FK violation. No data get loaded.
So if I add the -b 1 batch size option, it loads all data UNTIL the first FK violation, but nothing after that.
I want to load EVERYTHING ... except for the violations. But bcp won't let me. Is there a way?

In our environment applications are using a DNS name which points to the physical server ip address. Now we are planning to move to 2014. We are planning to have servers in different subnets so we will be having two ip adresses for listener. How we can point the DNS to the listener ips? If failover happens can the DNS point to the exact ip address of the listener where it's primary node?

What is the best approach for a read only copy of a database that is ~ 1TB. The primary database is fed nightly with an ETL process. We are currently trying to duplicate the ETL to read only server but that process is not going well. So we are looking at other options to let SQL make the copy.
The primary database is on a Win12R2 with SQL 12 or 14, a 2 node A/P failover cluster.
The read only copy will be on a Win12R2 with SQL 12 or 14. It is not a requirement to fail over to the read only copy if the primary should go down.
What would best the approach to accomplish the end result?
