SQL Server Admin 2014 :: Filegroup By Table Category
Oct 14, 2015
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?

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?

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.

My question is: How can I insert a row for each unique TemplateId. So let's say I have templateIds like, 2,5,6,7... For each unique templateId, how can I insert one more row?

I'm having problems with the following code:
--DROP MASTER KEY
--GO
USE master;
CREATE MASTER KEY
ENCRYPTION BY PASSWORD = 'Pass@word1';
GO
USE master;
[code]....
What am I missing? What do I have to do if I get in a situation where I need to back out and start over?

I am trying to replicate data from a view in the publisher to a table in the subscriber (transaction replication). I do not need the view's base table, or the view itself, replicated to the subscriber. I only want to data from the view to feed a table in the subscriber.
Is this possible?

With all the new functionality, can 2014 now restore a single table from a standard backup without using any third party tools? I have looked, but can't see this listed as a feature (though that doesn't mean it's not there, maybe I've just missed it).

I have a master table with after insert trigger on it.. When record is inserted into master table, the trigger fires and is captured in the backoffice table. In case the trigger fails, my record is neither in the master table nor in the back office table..
Is there anyway to capture the record either in the master table or in a separate table.

I am having an issue in determining the correct size of a table.
I have a tableA in some DB on transaction server (Enterprise Edition), this table is being replicated in reporting server DB (Standard edition).
When I check the space used by this table in both the databases i see noticeable difference.
I am using EXEC sp_spaceused 'tableA' to determine the space.
Transaction Server
------------------------------------------------------------------------------
name rows reserveddata index_size unused
TableA1439999 695416 KB507048 KB182912 KB 5456 KB
Reporting Server
-------------------------------------------------------------------------------
name rows reserveddata index_size unused
TableA1439999 656904 KB483664 KB172680 KB 560 KB
So I wanted to know what could be the possible reasons for this difference ?

I have a job scheduled that imports a table from a Oracle database. The job runs at 3am and reports success. But for some reason when i query the table to see how many records there are, I see the same row count as the day before (it should increase everyday- student enrollment). When i execute the package manually, the table updates fine.

The error is "The table with Name of 'Table Name' does not exist.An error occurred when loading the Model."
We get this error when we try to check the properties of an analysis server using SQL Server Management studio. We have resolved this issue twice by Stopping the SQL Server analysis service,removing db folders from Analysis Server Data folder and starting the services back on. The db folder that we removed was advised by the BI team.
The SQL Server Analysis Server is 2012 SP1

Is there any way to enforce table references in stored procedures? For Example, we have stored procedures with a ton of different formats, "dbo.table", "table", "db.dbo.table", etc. Can we make it so that for every stored procedure, the reference must be at least "dbo.table"?

I am setting up extended events more or less just fine, however I am a bit confused as to how to read and load them into a table for querying. In particular the offset part - is there a way to load just a given dates worth in?
I've got the files configured to be 20MB before rolling over, the XE is running all the time.
So if i load in the full file now, say that covers 2.5 days worth, when I load it again tomorrow to get the updated data I'm also reloading today, which is a waste?
I presume I am going about this wrong, but lack an example that really goes into detail of practicalities of loading this data.

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 try to load data into a memOpt table (INSERT INTO ... SELECT ... FROM ...). The source table has a size about 1 Gb and 13 Mio Rows. During this load the LDF File grows to size of 350 GB (until the space if the disk is run out of space). The Server has about 110 GB Memory for the SQL Server reserved. The tempdB doesn't grow. The Bucket Size in the create statement has a size of 262144. The Hash key as 4 fields`(2 fields have the datatype int,1 has smallint, 1 has varchar(200). ) The disk for the datafiles has still space for the datafiles (incl. the hekaton files).
How can I reduce the size of the ldf files during the load of the data ?
