Parallel Query processing in SQL server

In stored procedure we are processing nearly 10 update statements with in a transaction, because of synchronous query processing it is taking time to process all these queries ,I need to execute all the quires asynchronous processing can any
one help me out how to process quires asynchronously?

Hi,
For most cases the need of using asynchronous
statements processing
is resolving using Service Broker
SQL Server Service Broker provides native support for messaging and queuing applications in the SQL Server Database Engine. Service Broker, internal or external processes can send and receive guaranteed, asynchronous messaging by using extensions to
Transact-SQL.

TCP connection closed but a child process of SQL Server may be holding a duplicate of the connection's socket in SQL2008R2

Hello,
I do get the below SQL error in production environment intermittently:
TCP connection closed but a child process of SQL Server may be holding a duplicate of the connection's socket. Consider enabling the TcpAbortiveClose SQL Server registry setting and restarting SQL Server. If the problem persists, contact Technical
Support.
According to the post I search in MSDN, the above error is fixed in SQL2008R-CU6, but I have SQL2008R2-SP02 CU09 patch in production environment and the above error still occurred intermittently. I am running SQL2008R2 SP02 CU09 patch with Windows 2008R2-SP01.
I would like to know if anyone has the same error happened to their SQL environment after applied SQL2008R2-SP02 CU06 patch and later.
Any suggestion would be helpful.
Best regards,
PL.

Hello,
What happen if you apply the changes on the registry explained on the workaround section of the following article?

Parallel query processing. (Max Processors)

Hi Guys,
We have a System running on SQL 2000, and it configured to use all available processors.
(Server properties>Processor)
I am about to change it to use 1 processor as per microsoft recommendation, but there another option when you select fixed number of processor instead of all available processors, which is
"Minimum query plan threshold for considering queries for parallel execution(cost estimate)"
http://picasaweb.google.com/lh/photo/8N0-WQt3m23vEiupxdjtwQ?feat=directlink
can anybody suggest me, how do you estimate this number. or you guys can post what is current threshold value in your SQL 2000 server environment. (I dont see this option in SQL 2005,probably its handled automatically).
Thanks Guys

Hi Fan Yu
SAP on Microsoft SQL Server
In the above document, page 44 under section Max degree of parallesim, microsoft recommends this value to be set to 1.
(Reasons are discussed in the white paper)
Like i said, SQL 2000 has one more option regarding max degree of parallelism, i.e "Minimum query plan threshold for considering queries for parallel execution(cost estimate)"
http://picasaweb.google.com/lh/photo/8N0-WQt3m23vEiupxdjtwQ?feat=directlink
Probably i was not clear in my question, this is not related to number of processors and data files, but number of processors used by the query engine at a given time.(max degree of parallelism).

DeadLocks on Query Notifications with SQL Server 2008 SP3

Hello,
according to this article https://support.microsoft.com/kb/975090 the issue with deadlocks on query notifications should be fixed with SQL Server 2008 SP3 (10.0.5500.0). But we still get deadlocks in the following manner:

Is there any need to install another fix?
Thanks in Advance!

Hello,
SQL Server 2008 SP4 and all cumulative updates of SP3 do not have fixes related to deadlocks.
Maybe the following workarounds and solutions can help in your scenario.
http://stackoverflow.com/questions/3707137/understanding-deadlocks-with-sql-server-query-notifications
Deadlock Prevention. In case you need to lock multiple conversation groups in a transaction, you need to take the same order to lock the different conversation groups in all transactions, otherwise you will have a deadlock issues.

How about if you make the query into a view on ORACLE and SELECT from the view?

Oracle query on dblinked SQL Server tables returns ORA-00904 error

Hi,
I have created a dblink to a SQL Server database from Oracle using Generic Connectivity.
The following query returns ORA-00904 Invalid Identifier error in the WHERE clause (tblEmp.Empno)
SELECT "EmpNo","EmpName", "DeptName"
FROM tblEmp@sqlserver,
tblDept@sqlserver
WHERE tblDept.DeptNo = tblEmp.Empno
I had to enclose the column names in double quotes due to case sensitivitiy of the columns, but I can't do the
same for the WHERE clause.
1) So, how do I fix this error ?
2) Also how do I include Deptno column with table alias in the columns list?
(Deptno is ambiguous in Emp and Dept tables)
Regards,
Sam

Alex
Because using the aliases all the time can become annoying and lead to disparate standards when used by multiple developers. For a one-off query I would go with aliases in the query but if the linked tables are going to be interrogated extensively I would prefer to create vanilla views of the underlying tables so that the aliases aren't necessary.
Just my opinion, it feels a bit cleaner to do it this way - you only do the work once in creating the view and then you don't need to worry about the case sensitivity of the linked database. You can also refer to the source in the name of the view so you don't have to think about different source databases with the same table names.
Cheers

Adding parameter to a MySQL query in MS SQL Server Report Builder

So I have a MySQL DB connected to MS SQL Server Report Builder via ODBC connector. Everything is fine, I can execute queries and put the fields into report.
But I can't add an parameter to the query.
Example query:
SELECT column1, column2 FROM table WHERE column3 = (@parameter1)
The result set is just empty. I think the problem is that I'm using MySQL and not MS SQL. Any suggestion?

Hello Alan,
Named parameters like @param works with SQL Server / .NET data provider, but not for OleDB, here you have to use the question mark instead
SELECT column1, column2
FROM table
WHERE column3 = ? and column9 = ?
When you assign the report parameter to query parameter you have to take care about the order of used ? in query

Query used by SQL Server Management Pack for monitoring database backups

I use SCOM 2012 R2 and the SQL Server Management Pack to monitor SQL Server database backups. I believe I am getting false positives. SCOM reports database are not backuped, while in fact they are. So I need to troubleshoot this. I suspect SCOM is querying
the backup history in the msdb database. I want to know which query SCOM uses.
I have tried looking in the monitor's definition but I suspect the query is embedded in the management pack files which are binary. I have also tried running a trace using the SQL Server Profiler on my test environment and overriding the interval to 60 seconds,
but I don't see a relevant query being executed. I also don't see the alert reappear so I suspect SCOM does not honor the interval in a way I would expect.
What query, or other method, does SCOM use to check database backups?
Thanks in advance.

Thank you both Ivan and Michael,
I only saw your messages by email and didn't see your screen shot before I extracted the query myself. In my own queries I calculate the backup age in hours instead of days because of daily full backups. Perhaps It will be a good idea to create my own monitors
from scratch like I used to do with Nagios.
I will study the vbscripts and might create my own version which allows the query to be entered as an parameter and move all code to a .Net class which can be called from vbscript as an COM object. This way I hope to reduce the vbscript code to an minimum
while keeping the flexibility of the SCOM Operations Console and the robustness of .Net. I suspect I want to make more non standard monitors in the future.

Arjen

What is the process for SQL Server 2005 patch update

hi,
i have 2 production SQL Server2005 Database servers in cluster ,
what is the process for applying patches.
Saidireddy

In 2005 you can do it in two ways...
Method 1 :
With SQL Server 2005,
when you start installing cluster service pack (or hotfix), it must be launched on the active node(node
that hosts the instance). When installing the Setup will launch simultaneously "remote silence" on all passive nodes. All nodes in the cluster containing the SQL Server instance are updated in the same time.
Method 2: First you can install in passive node then you can install in the active node, In this way you can save your down time ( If you start in the active node it will check in the passive, and if its installed already then it skips that
and start applying in the active node ), but most of the DBA's follows only first method because they may not aware of this or just they follows Microsoft common method.
SQL 2008 and Later....
1. Apply the hotfix on pasive node N2
2. Reboot the passive node N2
3. Failover on SQL resource : the passive node become the active node
4. Apply the hotfix on the passive node N1
5. Reboot the passive node N1

Trouble Turneing on FileStream/Ad Hoc Query with new SQL Server 2014 64-BIt Version

SQL Server Help,
I have recently installed SQL SERVER 2014 on my Window 7 SP1 Acer laptop.
I am trying to do a simple upload of an Excel file into SQL Server using the OPENROWSET command:
Which I found requires some configuration change I attempted below.
When I execute this:
execute sp_configure 'show advanced options', 1;
RECONFIGURE;
execute sp_configure 'Ad Hoc Distributed Queries', 1;
RECONFIGURE;
GO
I get this message
Configuration option 'show advanced options' changed from 1 to 1. Run the RECONFIGURE statement to install.
Msg 5593, Level 16, State 1, Line 2
FILESTREAM feature is not supported on WoW64. The feature is disabled.
Msg 15123, Level 16, State 1, Procedure sp_configure, Line 62
The configuration option 'Ad Hoc Distributed Queries' does not exist, or it may be an advanced option.
Msg 5593, Level 16, State 1, Line 4
FILESTREAM feature is not supported on WoW64. The feature is disabled.
When I go to the SQL Server Services and Properties on the Server and try to change the FileStream options to be on..I get the error:
"There was an unknown error applying the FILESTREAM settings. Check the parameters are valid (0x80070002)."
Perhaps my issue is with the Windows Share Name: . I have put in a local driver C:\A_Excel....also the computer name, my user ID. Is there a special format or way to define a Share Name that I am unaware of?
Is there a way to fix this? Can I not load Excel files with a 64-Bit system? Or what is the easiest way that I can do this with my configuration?
Thanks for any help.

FILESTREAM feature is not supported on WoW64. The feature is disabled.
By the error message it seems you have a 64 bit OS, but have installed a 32 bit SQL Server and here in WoW64 mode filestream seems to be not supported. Install a 64 bit SQL Server instead.

Data discrepancy between Webi Report and same Query fired on SQL Server 2k5

Hi ,
We are facing an issue in BO XI R2.
We need to run a Webi report in which negative values for forecasting data for year 2011 and 2012 should be displayed.
When we are running this report for negative values, we are getting message u2018There is no data corresponding to this queryu2019.
Then we tried executing the same query on Database. Here at db level we got the correct required result.
So now we are not able to find the reason for data discrepancy .
Why the same query generated by Webi is providing correct data when fired on reporting database and not when running the Webi Report.
Checklist we have gone through for this troubleshooting is-
-Connections of Universe (Is universe pointing to same database or not)
-Any filter condition present at universe level and at report level.
Could anyone please help on this.
Regards,
Vaibhav

Vaibhav,
Have you tried the following when you are in WebI: go under the Edit Query panel, click on the "SQL" icon, and review the query that is getting generated? At this point you can also click on the "copy" option, then paste this query into your SQL application analyzer and run to see what results are generated. To me, it sounds like the portion trying to generate the "minus" sign might be getting tripped up causing the disconnect....
Thanks,
John

Query related to Sql Server

SQL Server 2012 : We would require a developer license for SQL 2012 Server and there might be 1-2 people accessing the server through SQL Client. This is for non-production use.
Do we need to buy a CAL license for this or just an additional edition of Developer license will do to access the Server.
I see that in your licensing document it is mentioned that “One license is required for each person that accesses or uses the software”
Please reply asap

Check this　
Licensing SQL Server for Non-production Use
The SQL Server 2012 Developer Edition is a full-function version of the SQL Server software—with all the features and capabilities of the Enterprise edition—licensed under the Developer Tools model, which is a "per user" model.
One license is required for each person that accesses or uses the software.
When using SQL Server software for development, test or demonstration purposes, only the users are licensed and there is no need for a corresponding license for the actual server systems running SQL Server software in this case.
As long as only licensed users have access to the software, customers can install as many copies of the software on any number of servers that are used exclusively for development, test or demonstration purposes. This
is significant, because it allows customers to run the software on multiple devices (for testing purposes, for
example) without having to license each non-production server system.

Query to get sql server version information?

Hi!
I'm new to sql and would appreciate it if anyone could show me the query that i need to type to get the server version information - I do not have direct access to the sql database (doing some work on an old website that runs on windows box w/ coldfusion :p)
appreciate it!

You could try this.
Select SERVERPROPERTY('productversion') As [Version],
SERVERPROPERTY('productlevel') As [Level],
SERVERPROPERTY('edition') As [Edition]
It will produce output like this.
Version Level Edition
