My main production server has four NUMA nodes with two SQL Server 2012 instances on it. One of the instances has the CPU affinity set to use only one NUMA node, and sys.dm_os_nodes reflects that correctly. The other instance has no affinity settings, so it should show all 4 NUMA nodes as online, I would think, but it shows Node 3 as offline, which happens to be the node that's online for the other instance. Is there a bug in SQL Server 11.0.3128 (Enterprise)?

We have several processes  inserting records for one Batch.

Recently we’ve had some long blocking so some of the inserts for a batch were blocked while the select statement to get a count of this batch ran ( we use read_committed_snapshot) and returned an incorrect count because it was missing the blocked inserts.

Additionally the time_updated is using getdate() and that stores the time the record is parsed not the time it is finally written to the database so it is not correct.

Is there any way to store the time the record is actually saved?

Is there any method to ensure all records for a batch are committed before we run the select of the count? This is a very busy process and we need correct counts.  We’ve thought of using some sort of separate queuing when inserting and then making sure the number of records in the queue match the database. Is there a better way?

Hello,

I observe issue with representation of Devanagari  characters (U+0940 and U+0947) :

In SQL server database I think DEVANAGARI VOWEL SIGN E is represented as less than to DEVANAGARI VOWEL SIGN II. 

I think it is a bug in SQL Server database, and should be represented in other way round i.e, U+0947 should be represented as >  from U+0940.

The steps to reproduce with T-SQL :

   create table test (c1 int, c2 nvarchar(50))

insert values:

   insert into test(c1, c2) values (1,N'पीपे का सबसे चौड़ा भाग') 
   insert into test(c1, c2) values (2,N'पी') 
   insert into test(c1, c2) values (3,N'पे') 

Fetch records:

sql1: select * from test where c2 > N'पे' order by c2;

2पी
1पीपे का सबसे चौड़ा भाग

// it should not return any row as no row is having value > 'पे'

sql2: select * from test where c2 > N'पी' order by c2;

1पीपे का सबसे चौड़ा भाग

// it should return one more row as 'पे' should be greater than 'पी'.

Thanks,

Mukesh

Hi all,

We have tens of SQL Server instances and currently they perform regular log backup every 15 minutes.

So far we have been using disk based backups, for example on local disks of servers or shared storage on SAN.

Recently we decided to buy a tape.

My question is that what happens if for example 10 jobs on different servers try to write backup to tape?

Because on disk based backup, the disks of destination will become slow but never reject the backupset. Does the same thing happen for tape or the tape will reject the write operation if requests are too high?

Thanks in advance,

Leila

All I want to do is is take 6 partitions down to  2 partitions. At first I didn't think it would be such a hassle...boy was I wrong. Is this even possible? I've provided all the information that I know. Can anyone offer any type of assistance? Or am I stuck with it like this? The Sea Gate external hard drive isn't mine...I wish it where. I couldn't get Windows to register it even though the device manager could recognize it. So I have no clue whats up?

Hi All,

Using SQL Server 2008 R2 in multiple servers.

1. Any script (links) for creating a manual maintenance plan? I would like to manually run the script for some databases in multiple servers.

2. It is a way to collect the statistics before and after the maintenance? I would like to show the improvement after the plan running.

3. Am I missing anything in this maintenance plan steps?

- Full Backup of the database.

- Transaction Log Backup.

- Check DB integrity

- Cleanup Backups more than two months

- Rebuild Indexes

- Reorganize indexes

- Shrink databases

- Update Statistics

Thanks for your help in advanced.

Best,

Thanks

Whenever I do a restore I always forget to reapply some database roles or application roles in post restore steps.We have one database of very different db roles,Grant permissions,Login and User permissions and they changes also frequently.

What dmv's I required to create  such script which will fetch all this data in form of create command and after restore I just have to run those create commands and all the rights should visible as before .

Hi,

I have a large table (about 60GB) with a Clustered Column Store Index (156 columns). The table is alsopartitioned (using SQL Server 2014 Developer Edition).

After the table was being populated with data for a while, I wanted to test the effects of Index Rebuild on the space used by the table.

I performed the test on a single partition.

I executed the following query to get an idea on how the segments are set up and how much disk space they take:

select object_name(object_id), partition_number, segment_id
, COUNT(DISTINCT column_id) AS NumOfColumns
, SUM(cs.row_count) AS Total_row_count
, AVG(cs.row_count) AS Avg_row_count
, MIN(cs.row_count) AS Min_row_count
, MAX(cs.row_count) AS Max_row_count
, SUM(cs.on_disk_size) AS Total_on_disk_size
, AVG(cs.on_disk_size) AS Avg_on_disk_size
, MIN(cs.on_disk_size) AS Min_on_disk_size
, MAX(cs.on_disk_size) AS Max_on_disk_size
from sys.column_store_segments as cs
inner join sys.partitions as p
on
	p.partition_id = cs.partition_id
where 1=1
and object_id = object_id('MyTable')
and partition_number = 10
GROUP BY object_name(object_id), partition_number, segment_id
ORDER BY segment_id

I also executed sp_spaceused on the table and noted its total size.

Then I executed an Index Rebuild on the one partition only of the clustered column store index:

ALTER INDEX [cci_MyTable] ON MyTable REBUILD PARTITION = 10

Then I executed the query above and sp_spaceused again and noted the changes.

The result was:

• Two new segments were created.
• The number of row counts per segment shuffled up (but the grand total remained the same).
• The grand total of on_disk_size became smaller by ~26 MB.
• The table size (from sp_spaceused) became BIGGER by ~12MB.

So my question is:

Why, even though the total partition size became smaller, the total table size became bigger?

Here are the detailed results of sp_spaceused before and after the rebuild:

Note that I executed the index rebuild on a single partition only (partition 10 in this case), and I'm executing sp_spaceused at the table level; the total number of rows in the table remained the same. But the reserved and data used increased, while the index_size remained the same.

This is all rather strange to me.

I would figure that the index rebuild would require some additional space as a working area, but when finished, this space will be marked as unused. So I would expect maybe the reserved column to increase, but the data column to decrease (since at the partition level, the total partition size actually decreased).

Any explanations? What could cause this?

Thanks

Hi,

When I create an SQL connection from my workstation within an Excel file, other users are unable to refresh the data.

Error Message:

            “[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified”

The connection string being:

DRIVER=SQL Server Native Client 10.0;

SERVER=SQLSERVER;

UID=*ME*;

Trusted_Connection=Yes;

APP=Microsoft Office 2010;

WSID=0347;

But they are able to refresh the data if I create the connection from their own workstation.

The connection string being:

DRIVER=SQL Server Native Client 10.0;

SERVER=SQLSERVER;

UID=*OTHERUSER*;

Trusted_Connection=Yes;

APP=Microsoft Office 2010;

WSID=0348;

I can refresh any connection from my workstation regardless of who created it.

I need all users to be able to refresh files that I have created from my workstation.

Presumably the issue is the SQL Server credentials, but if someone is able to confirm this and offer a solution I’d be most grateful.

I am using sql server 2005.My database is increamental databse daily new tranctions are add in it.By mistake i have deleted some transaction from that database table.How can i recover it.I dont have any other database backup.plz help me.

I have a question regarding XML indexes.

We have a table OVERLAY_ITEM_SEARCH_XXX with almost 5 million rows. The table has 2 columns – an identity column (bigint) and a SEARCH_VALUES column (XML). The XML column has a primary XML index and secondary XML PATH index.

The SEARCH_VALUES XML column contains a number of fields under the ATTRIBUTES node, e.g. SECTION_REF, but these are variable, as they are derived from user configuration.

The elements c121 and o870 represent client_id = 121 and overlay_id = 870. There are several clients and overlays within the database.

So a typical SEARCH_VALUES XML value for a particular row may look like this:

<c101>

       <o777>

              <SECTION_REF>1/2/567</SECTION_REF>

              <NAME>FRED</NAME>

<POSTCODE>W1 21A</POSTCODE>

       </o777>

</c101>

Performing the following 2 queries, for which no rows are found

1. A TOP 1 query

selectTOP 1 * from overlay.OVERLAY_ITEM_SEARCH_XXX s

where s.SEARCH_VALUES.exist('c121/o870/ATTRIBUTES/SECTION_REF/text() [contains(.,"J1")]') = 1

2. A SELECT * query

select*from overlay.OVERLAY_ITEM_SEARCH_XXX s

where s.SEARCH_VALUES.exist('c121/o870/ATTRIBUTES/SECTION_REF/text() [contains(.,"J1")]') = 1

The  ‘SELECT *’ query utilises the secondary XML index and runs in 9s, whereas the ‘TOP 1’ query doesn’t use the secondary XML index an takes 100s.

Why does the TOP n query not utilise the secondary XML index? N.B. This is from the actual query plan.

It seems that any query we try other than "select *" fails to use the index, e.g. IF EXISTS(SELECT *...)

Does anyone have any similar feedback from using XML indexes on large tables?

Note that the search for the searchable value (e.g. in the example above ‘J1’), needs to be a ‘contains’ type search.

This is using SQL Server 2012 SP2

Any help/comments would be appreciated.

Hi,

I have few column store in different table in DB. When I was analyzing the column store index  one  index have 12 segments ,When I looked into sys.column_store_segments for  all the 12 segments min_data_id and Max_data_id is "NULL".

In which scenarios these values become null? Will this cause a performance issue in queries?

Hi. I have a script that I've been using a while that does some SQL configuration.  I just got done with new elevation, UAC, and share access issues for my SQL install scripts.  Now I can't get the first configuration script to run.  Anyway, I have SQL 2012 developer install on my desktop along with VS 2012.  I use the following to load the assemblies I need. 

[reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | Out-Null
[reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.SqlWmiManagement") | Out-Null

It still works with SQL 2008 R2 servers.  It stopped working with SQL 2012 servers.  I get he following error. 

The following exception was thrown when trying to enumerate the collection: "SQL Server WMI provider is not available on SQLSERVERNAME."

Also, I tried to use http://msdn.microsoft.com/en-us/library/hh245202.aspx, but I have a different reg value.  Mine has a sqlps110 rather than sqlps.  Also, the SQLPS.exe and the SQLProvider.Format.ps1xml files are in different folders. 

D:\SQL2012 (x86)\110\Tools\Binn\SQLPS.exe

Hi 

  I just restated one server and started getting error from MSDTC and not able to bring online..IT has 2 node windows 2012 R2 cluster , SQL server 2012 is installed on it.

Cluster resource 'MSDTC' of type 'Distributed Transaction Coordinator' in clustered role 'MSDTC' failed.

Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it.  Check the resource and group state using Failover Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.

Event ID 1069

----------------------------------------------------------------------------------

Event ID 1205 

The Cluster service failed to bring clustered role 'MSDTC' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered role.

---------------------------------------------------------------------

Event ID 1254

Clustered role 'MSDTC' has exceeded its failover threshold.  It has exhausted the configured number of failover attempts within the failover period of time allotted to it and will be left in a failed state.  No additional attempts will be made to bring the role online or fail it over to another node in the cluster.  Please check the events associated with the failure.  After the issues causing the failure are resolved the role can be brought online manually or the cluster may attempt to bring it online again after the restart delay period.

Any work around if anyone has solved this problem..?

Thanks
