SQL Server TG Query Optimization
We are using Oracle Transparent Gateway 9.0.1.1.1 to connect an Oracle (Windows 2000) 9.1.7.4.0 database to a SQl Server 2000 SP2 database.
When we use two simple queries to retrieve information from the gateway, the data is returned with a response time of less than 100 milliseconds. When we combine these queries into a single query, data is returned with a response time of over 20 seconds.
QUESTION: Is there any documentation as to the "Do's" and "Don'ts" of querying across the TG for best response times? Anything concerning joining Oracle and SQL Server tables in particular would be appreciated.

Scott,
The gateway does not create any type of locks. Could you provide the sql statements in your session. Also take a look at the trace generated by the SQL Server profiler

SSRS - SQL Server Spatial Query
Hi, I was hoping someone could help me.
I'm creating an SSRS report with Map and importing points via SQL Server Spatial query. I have a db table with 8,000 points bu the import only ever brings in the first 2,000 queried (no matter what the filter is). Is there a limitation in SSRS that can be
changed via a configuration setting?
Many thanks in advance for any help on this,
Steve.Really appreciate you coming back so quick Olaf.
No its a straightforward query (select AccountNum, Name, Address, Longitude, Lattitude, UrbanArea, County, MI_STYLE, MI_PRINX, SP_GEOMETRY from <table>)
Just to give the whole picture. I had 8,000 points in MapInfo version 10. I imported them to SQL Server 2012 via MapInfo Easy Loader.
The SQL Server spatial points import to SSRS and the Bing overlay map works great (so they import to correct space) but its only a subset of the points that import. I can pick any subset using the WHERE clause but I cannot get all 8,000 points.
I was hoping there was a configuration setting somewhere in SSRS that was causing the problem. -
Error [hyt00] [microsoft][odbc sql server driver] query timeout expired
I have the below network setup:-
1. Its a simple network at my father's office at a small town called Ichalkaranji (District - Kolhapur, Maharashtra).
2. We are using private network range 192.168.1.xxx with two Windows Server 2003 Enterprise Edition with SP2 licensed copies and 15 local Windows 7 clients who are only using Server A.
3. The network is having a TP-Link Braodband Router Connected to internet with the IP 192.168.1.1.
4. Both there Windows Server 2003 Enterprise Edition with SP2 are running separate SQL Server 2005 Express with Advanced Services, you can treat them as Server A (Problematic Server with IP of 192.168.1.2)
and Server B (this is not having any issue with IP of 192.168.1.3).
5. Server A is also being used by 6 Remote users from our Kolkata office using DDNS facility through the NO IP client software which installed separately on both the servers. Kolkata remote users
do not use OR access the Server B.
6. Server B is being used by only 2 Remote users from our Erode office (Under Salem District, Tamilnadu) using DDNS facility through the NO IP client software which installed separately on both
the servers. Erode remote users do not use OR access the Server A.
7. The front end application which running separately on both the servers have been developed in VB by a local vendor at Ichalkaranji (District - Kolhapur, Maharashtra).
8. Both Servers are having the same database structure in terms of design and tables format. Only difference is that both the servers are being used separately.
9. This error OR problem is only related to Server A, where on the clients we get the message "error [hyt00] [microsoft][odbc sql server driver] query timeout expired" every now and then.
10. We have to frequently reboot the server whenever we get this message on the client machines. May be after rebooting every thing works perfectly for 2 hours / 5 Hours / may be one full day but
the the error will come back for sure.
11. Current Database back up size on Server A is around 35 GB and take around 1 hour 15 minutes daily to take the back up.
12. Current Database back up size on Server B is around 3 GB and take around 5 to 10 minutes daily to take the back up.
13. One thing I have noticed is that when ever we reboot Server A, for some time sqlsrvr.exe file will show memory usage of 200 to 300 MBs but it will start using slowly, what i understand is that
this is the way SQL Server works.
14. Both the Servers are also running Quick heal Antivirus Server Edition separate licensed copies also.
15. Server B is also running Tally ERP 9 Licenses copy which is being used locally by 15 users of Ichalkaranji (District - Kolhapur, Maharashtra) same users
Can any one help to resolve this issue. Any help will be highly appreciated.The error message "query timeout expired" occurs, because by default many APIs, including ODBC only waits for 30 seconds for SQL Server to send any output. If no data has been seen for this period of time, they tell SQL Server to cancel execution
and return this error to the caller.
This timeout could be seen as a token that the query is taking too long time to execute and this needs to be fixed. But it can also be a pain in the rear parts, if you are content with a report taking five minutes, because you only run it once a day.
The simplest way to get rid of the error is to set the timeout to zero, which means "wait forever". This is something your vendor would have to do. This may, however, not resolve the problem, as the users may just find that the application is hanging.
To wit, there are two reasons why the query takes more than 30 seconds to complete. One is that there is simply that much work to do. This can be reduced by adding indexes or by doing other tuning, if the execution time is not acceptable. The other possibility
is blocking. That is, there is a process blocking this query from completing. This is much more likely to require attention.
It is not clear to me, whether the vendor has developed the database part as well. In this case, you should probably call the vendor's support desk to have them to sort this out.
Finally, I am little puzzled. You say that you are using Express Edition, but one of the databases is 35 GB in size. 35 GB is far above the limit for Express Edition.

Ah, just spotted it's a delete statement - you won't be able to do it using subquery factoring in Oracle.
I had a go at trying to convert for you, but notice that you reference the cte from inside the cte... I can only assume you have a table called cte too...
DELETE FROM dbo.tb1
WHERE col1 = 12
OR col2 IN (SELECT col1 FROM cte)

Copy and Paste from SQL server to Query Generator eliminate spaces
Hi:
My query is run perfectly on SQL server.
However, when I copied it to Query Generator in SAP B1, it can not be run. When I look closely I see that some spaces have been truncated for example between the fieldname and key words like FROM, LEFT OUTER JOIN. I have to then going through the Query Generator in SAP B1 to put in the spaces in appropriate places. This process took long time and require very close attention and did not make any sense to me, since my query already work in SQL server query manager.
Is there any way that we can make Query Generator in SAP B1 keeping the same format (ie. not eliminate the spaces) as in SQL server Query Manager?
Best Regards,
Phong Nguyen.Here is what I mean:
SELECT YEAR(T1.DocDate) YEAR_NO, DATEPART(wk,T1.DocDate) WEEK_NO,SUM(T1.LineTotal) TotalShrinkage_Sales, (SUM(T1.LineTotal)/SUM(T1.Total_Sales)) Percent_Shrinkage, SUM(T1.Total_Sales) Total_Sales,COUNT(DISTINCT T1.Shrinkage_No) Shrinkage_Volume, SUM(T1.TotalCost) TotalShrinkage_CostFROM (SELECT V0.ITEMCODE, V0.DocEntry Shrinkage_No, V0.DocDate, V0.LineTotal, 0 Total_Sales, V0.TotalCostFROM dbo.V_SHRINKAGE_TOTAL V0 WHERE V0.TransType='Shrinkage'UNION ALLSELECT V1.ITEMCODE, null Shrinkage_No, V1.DocDate, 0 LineTotal, V1.LineTotal Total_Sales, 0 TotalCostFROM dbo.V_Sales_Invoice V1UNION ALLSELECT V2.ITEMCODE, null Shrinkage_No, V2.DocDate,0 LineTotal, V2.LineTotal Total_Sales, 0 TotalCost FROM dbo.V_Credit_Note V2) T1WHERE DATEDIFF(wk,T1.DocDate,getdate())<=12GROUP BY YEAR(T1.DocDate), DATEPART(wk,T1.DocDate)ORDER BY YEAR(T1.DocDate) ASC,DATEPART(wk,T1.DocDate) ASC
You can see the the third line (top down) the space between the field TotalShrinkage_Cost and FROM has been eliminated.
Also you can see that on the 4th line (top down) the space between the field V0.TotalCost and FROM has been eliminated.
Also in the 5th line (top down) you can see: V0.TransType='Shrinkage'UNION ALLSELECT --- spaces have been eliminated between 'Shrinkage" and UNION and ALL and SELECT
The list can go on.
Can you help there?
Thanks,
Phong Nguyen. -

Hi Team ,
I have some queries for MS SQL server , can you please clarify the below points :
Can I buy licenses for SQL 2008 R2 or do I need to buy license for MSSQL server 2012 license and then downgrade it?
Would there be any additional cost for downgrade ?
If I want to buy license for MSSQL 2008 ,would it be “per processor “ or “per core” for Virtualization i.e. which of the two licensing policies will apply.
Please clarify on this.relevant microsoft oem docs/links would be really helpful

1. You can buy license for 2008 R2, if your requirement is 2008 R2 dont buy 2012 its costly.. You dont need to buy 2012 license and downgrade it.I am not sure whether it is possible or not licensing expert will be in better position to answer this question.
2.Licensing expert can tell better.
3.Licensing expert can tell better. Please use information provided by Kalman.But i still suggest you to go for 2008 R2 IF that suits your requirement
PS: This is technical forum, Licensing question must be directed to licensing expert
Please mark this reply as the answer or vote as helpful, as appropriate, to make it useful for other readers

How to fetch presence in Lync 2013 from SQL server (using query)
We are running Lync 2013 setup with 5 FE and 2 BE SQL (mirrored) servers.
How can i get presence information for our users by script or SQL queries?
My Concern is to fetch out current presence information of a list of users (CSV file) by script (Powershell or SQL query) for automation purpose. So that one need not to go to Lync 2013 (or anything) Client for every single user, to check their corresponding
presence.
E.g Say a service desk agent is handling tickets of 200 users per day. So it will be time consuming for him/her to go to Lync 2013 client and check presence for every user. It would be better for SD agent to operate, if we could make a script to fetch presence
status for the list of 200 users.
We will fetch the information when required and send a mail to him/her.
i have asked this question under Presence and IM forum.

Sql Server Express Query String error
I am having trouble trying to filter my sql database using the query string against a date column in my database. I set a date variable = "dd/mm/yyy" format but when I apply that in the sql query as:
StartPeriod = CDate("01/" & Today.Month.ToString & "/" & Today.Year.ToString)
EndPeriod = CDate(Today.Day.ToString & "/" & Today.Month.ToString & "/" & Today.Year.ToString)
At this point StartPeriod = #04/01/2015# and EndPeriod is #04/27/2015#
sql = "SELECT * FROM Transactions WHERE ((PaidOutDate IS Null) OR (TransDate >= '" & StartPeriod & "' AND TransDate <= '" & EndPeriod & "')
When I execute the Sql command I get this error:
"Conversion failed when converting date and/or time from character string"
My Current Culture is {en-AU}
Any help is appreciated.
Brad
BHendVisakh,
Further to the problem above. Your suggestion worked well on my laptop, but when I transferred the program to my desktop it failed with the error: "Conversion failed when converting date and/or time from character string" again. Both
computers are running the same version of Windows 8.1, both running the same version of vs express 2012 and both running the same version of ssms. Both Windows 8.1 versions have the same English (Australia) as the Region and language. The only
difference that I can find is that while both have a CurrentCulture of {en=AU} and CurrentUICulture of {en-GB} the laptop, where the program works has an InstalledUICulture of {en-GB} and the PC where it doesn't work has an InstalledUICulture of {en-US}.
Do you think this could be the problem? If so, how would I change the InstalledIUCulture?
As you can tell I am way our of my depth here, I've looked in the Control Panel and both computers appear to have the same settings for options that I think are relevant, but of course there could be hundreds of other settings nI don't know about.
I've also progressively worked through the Registry on both computers comparing their settings but could find nothing relevant.
Any suggestions of where to look?
Thanks Again

SQL Server 2008R2 SP2 Query optimizer memory leak ?
It looks like we are facing a SQL Server 2008R2 queery optimizer memory leak.
We have below version of SQL Server
Microsoft SQL Server 2008 R2 (SP2) - 10.50.4000.0 (X64)
Jun 28 2012 08:36:30
Copyright (c) Microsoft Corporation
Standard Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1)
The instance is set MAximum memory tro 20 GB.
After executing a huge query (2277 kB generated by IBM SPSS Clementine) with tons of CASE and a lot of AND/OR statements in the WHERE and CASE statements and muliple subqueries the server stops responding on Out of memory in the internal pool
and the query optimizer has allocated all the memory.
From Management Data Warehouse we can find that the query was executed at

On the other side MDW reports that the MEMORYCLERK_SQLOPTIMIZER increases since the execution of the query up to the point of OUTOF MEMORY, but the Average value is 54.7 MB during that period as can be seen on attached graph.
We have encountered this issue already two times (every time the critical query is executed).Hi,
This does seems to me kind of memory Leak and actually it is from SQL Optimizer which leaked memory from buffer pool so much that it did not had any memory to be allocated for new page.

Can you post complete DBCC MEMORYSTATUS output which was generated in errorlog. Is this the only message in errorlog or there are some more messages before and after it.
select (SUM(single_pages_kb)*1024)/8192 as total_stolen_pages, type
from sys.dm_os_memory_clerks
group by typeorder by total_stolen_pages desc
and
select sum(pages_allocated_count * page_size_in_bytes)/1024,type from sys.dm_os_memory_objects
group by type
If you can post the output of above two queries with dbcc memorystaus output on some shared drive and share location with us here. I would try to find out what is leaking memory.
You can very well apply SQL Server 2008 r2 SP3 and see if this issue subsides but I am not sure whether this is fixed or actually it is a bug.
Please mark this reply as answer if it solved your issue or vote as helpful if it helped so that other forum members can benefit from it

Query: SQL Server Book Recommendations
Hi folks!
There are Books Online. There are the SAP Notes and Documents created by people like Jürgen Thomas (THANKS!!!) ...
There are many sources of information in the WWW - blogs, documents, discussons ...
And there are many BOOKS. Too many ...
I ask you to recommend your favourite books about SQL Server.
Your recommendations should help all of us to buy those books which are helpful ...
Kind regards, RudiHi Rudolf,
Do you focus only on SQL server, not including Windows Server Failover Cluster and SAP? If yes, I recommend you to ask in MSDN -> Database Engine.
Because this is a SAP on SQL forum, I will talk a little bit about WSFC and SAP. Here is my MATERIAL list. Hope this helps.
PS: These are very useful for troubleshooting and performance optimization. Regarding to reviews, there are so many people wrote in Amazon in great detail. I will skip it.

Selecting from a SQL Server 2005 with long column names ( 30 chars)
Hi,
I was able to set up a db link from Oracle 11.2.0.1 to SQL Server 2005 using DG4ODBC.
My problem is that some column names in the Sql Server are longer than 30 chars and trying to select them gives me the ORA-00972: identifier is too long error.
If I omit these columns the select succeeds.
I know I can create a view in the sql server and query it instead of the original table, but I was wondering if there's a way to overcome it with sql.
My select looks like this:
select "good_column_name" from sometable@sqlserver_dblink -- this works
select "good_column_name","very_long_column_name>30 chars" from sometable@sqlserver_dblink -- ORA-00972ThanksI tried creating a view with shorter column names but selecting from the view still returns an error.
create view v_Boards as (select [9650_BoardId] as BoardId, [9651_BoardType] as BoardType, [9652_HardwareVendor] as
HardwareVendor, [9653_BoardVersion] as BoardVersion, [9654_BoardName] as BoardName, [9655_BoardDescription] as BoardDescription,
[9656_SlotNumber] as SlotNumber, [9670_SegmentId] as SegmentId, [MasterID] as MasterID, [9657_BoardHostName] as BoardHostName,
[9658_BoardManagementUsername] as BoardManagementUsername, [9659_BoardManagementPassword] as BoardManagementPassword,
[9660_BoardManagementVirtualAddress] as BoardManagementVirtualAddress, [9661_BoardManagementTelnetLoginPrompt] as
MANAGEMENTTELNETLOGINPROMPT, [9662_BoardManagementTelnetPasswordPrompt] as MANAGEMENTTELNETPASSPROMPT,
[9663_BoardManagementTelnetCommandPrompt] as MANAGEMENTTELNETCOMMANDPROMPT FROM Boards)performing a select * from this view in sqlserver works and show the short column names
this is the error i'm getting for performing a select * from v_boards@sqlserver_dblink
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Microsoft][SQL Native Client][SQL Server]Invalid column name 'BoardManagementTelnetLoginProm'. {42S22,NativeErr = 207}[Microsoft]
[SQL Native Client][SQL Server]Invalid column name 'BoardManagementTelnetPasswordP'. {42S22,NativeErr = 207}[Microsoft][SQL Native
Client][SQL Server]Invalid column name 'BoardManagementTelnetCommandPr'. {42S22,NativeErr = 207}[Microsoft][SQL Native Client][SQL
Server]Statement(s) could not be prepared. {42000,NativeErr = 8180}
ORA-02063: preceding 2 lines from sqlserver_dblinkI also tried replacing the * with specific column names but it fails on the columns that have a long name (it doesn't recognize the short names from the view)
what am I doing wrong?
