I have a server 2008 R2 that while in Explorer on the left navigation pane show “Network” and under that a list of workgroup computers (it’s a file server) I have one computer in that network thats name is blue and underlined. Is there significance to this?

Scrip an select from linked Oracle database in Management studio gives multiply fields

AnnaLena — Wed, 30 May 2012 11:42:07 +0000

In SQL Server 2008 R2 Management studio under Linked servers I want to script a select from an Oracle database table. The result is that many of the fields occur three times. What can the reason for that be? See this example: SELECT [RATETYPE],[RATETYPE],[RATETYPE] ,[FROMCURRENCY],[FROMCURRENCY],[FROMCURRENCY] ,[TOCURRENCY],[TOCURRENCY],[TOCURRENCY] ,[VALIDFROM],[VALIDFROM],[VALIDFROM],[EXCHRATE] ,[FROMFACTOR] ,[TOFACTOR] ,[CREATIONDATE],[CREATIONDATE],[CREATIONDATE] FROM [MyServer]..[MyDB].[MyTable]

User’s seeing timeouts (the box itself is doing little). ANyone found a way to overcome this error?

Error Message in SQL Server 2008 code.

JKJK — Wed, 05 Oct 2011 11:20:55 +0000

Hi, I am currently going through the Tutorials on SQL Server Management Studio 2008 R2.

One of the samples instructs me to run the following code:

SELECT Mgr.EmployeeID AS MgrID, Mgr.LoginID AS Manager, Emp.EmployeeID AS E_ID, Emp.LoginID, FROM EmployeeDemo AS Emp LEFT JOIN EmployeeDemo AS Mgr ON Emp.ManagerID = Mgr.EmployeeID ORDER BY MgrID, E_ID;

[em]When i execute the above code i get the following error message:[/em]

[strong]Msg 156, Level 15, State 1, Line 4 Incorrect syntax near the keyword ‘FROM’. [/strong]

[strong]Any idea’s what the problem might be?[/strong]

[strong]Thanks[/strong]

Challenge improving query performance on large tables

Sport2000 — Tue, 27 Sep 2011 14:21:07 +0000

Hi,

Here’s the structure of the db I’m using: * Table frs_ArticlesBDFournisseur which contains article main data.One row per article/color. Key is Refrefart (int). Size is over 220000 rows at the momemt. Only index is the PK (clusterred). * Table frs_ArticlesBDFournisseurTaille contains all the various sizes and barcode for the corresponding article/color from the previous table. Key is RefREFARTTAILLE (int). Size is over 1200000 rows at the moment. refrefart column also exists in this table to link with the previous table, altough there is no physical constraint linking the 2 tables. Indexes are PK (clustered), refrefart (non clustered) and refrefart,taille,codeean,codeeanfrs (non clustered).

Here’s what I want to do: I work at headquarters of franchise shops. I have to collect data from each selling point, match it with our own database (the one discribed above) to normalise the incoming data and complete it with more details. The best way to match an article is to use its barcode (when it exits in the shop data). We pack up to 2 barcodes with every article (callled CodeEan and CodeEanFrs from frs_ArticlesBDFournisseurTaille). I need to complete the information I have with the article size (called taille from frs_ArticlesBDFournisseurTaille), the article’s season (called Saison from frs_ArticlesBDFournisseur) and the number of different season the article has been existing in (to know whether it is a one season product or a permanent product).

Here’s the challenge for the query at hand: There is no constant data in frs_ArticlesBDFournisseurTaille with which I can do a GROUP BY. I need to get the latest product data (in case there is more than one season) and the total number of seasons.

Here’s the query I’ve designed: SELECT M.*, ART_REF, A.ART_PSEUDO, ART_NOM, ART_FEDAS, ART_ANNEECREATION, COU_CODE, COU_NOM, TGF_NOM, MRK_IDREF, MRK_NOM, MRK_NOM_ORI, CBI_EAN, CBI_EANFRS, B.RefRefArt, B.Taille AS sp2kTaille, CASE when B.CodeEan = ” then null else B.CodeEan END AS sp2kEan, CASE when B.CodeEanFrs = ” then null else B.CodeEanFrs END AS sp2kEanFrs, B.Saison, Coalesce(B.Pos, 0) as Permanent FROM gin_Mouvements M LEFT JOIN gin_Articles A ON M.MOV_ARTID=A.ART_ID LEFT JOIN gin_Couleurs C ON M.MOV_COUID=C.COU_ID LEFT JOIN gin_Tailles T ON M.MOV_TGFID=T.TGF_ID LEFT JOIN gin_Marques N ON A.ART_MRKID=N.MRK_ID LEFT JOIN gin_Ean E ON (M.MOV_ARTID=E.CBI_ARTID AND M.MOV_COUID=E.CBI_COUID AND M.MOV_TGFID=E.CBI_TGFID) OUTER APPLY (SELECT TOP 1 T.RefRefArt, CodeEan, CodeEANFrs, Taille, Art.Saison, Rank() over (order by T.RefREFART ASC) as Pos FROM frs_ArticlesBDFournisseurTaille T LEFT JOIN frs_ArticlesBDFournisseur Art ON T.RefREFART=Art.RefREFART WHERE (CodeEAN = E.CBI_EAN OR CodeEANFrs = CBI_EANFRS OR CodeEANFrs = CBI_EAN OR CodeEAN = CBI_EANFRS) ORDER BY RefREFART DESC) B

Query explained: All the first part, with all the left join, is to gather the data, relatively small, from the shops. There is no performance issue here. I’ve used an outer apply to avoid having to do a left join and the ON conditions which I couldn’t get to work to return at the same time the max(refrefart) and the total number of season; remember I can not make a group by.

Performances: This query runs at a 20row/s at best (nearly 20s to return 500 rows). The data in both tables described at the beginning is bound to increase twice a year by about 10000 new products and 6 times more for the barcodes. I’m afraid the performances will be degrading even more soon.

Advice ?: If anyone can see how to improve the query or rewrite the query differently or improve the db or else … please let me know.

Stats: Execution plan sum up: it is spending 57% on Nested Loops (Left Outer Join) and 40% on Index Scan (NonClustered)[sp2k_staging].[dbo].[frs_ArticlesBDFournisseurTaille].
Thank you.

connecting to SQL server with mdf files

Makoelaw — Sat, 24 Sep 2011 00:52:27 +0000

What is the best way to connect a website on a VPS to sql server 2008 R2 express, using MDF files as databases. The VPS is running on server 2008 R2. I installed the same environment on the development computer. IIS gets a connection because it sees the users that are in the ASPNETDB.MDF file. (Beside that I have another database.) But as soon as I run the website and try to log in, the application crashes. I tried using integrated security and user instance in the connectionstring in the webconfig file, but get the error that the user instance could not be created. I made a user in sql server but that user can only be linked to existing databases (so MASTER) and when logging in to the website i get the error that ASPNETDB.MDF could not be created in the MASTER database because that file already exist (so this would be completely wrong). So how can I connect it in the right way? I would rather keep on using MDF files in the App_Data directory of the website, but is that a good thing? Is it secure on the VPS?

sys.conversation_endpoints build up

Shellz — Fri, 23 Sep 2011 23:40:12 +0000

It Seems that there is a lot of problems with SB cleanup? I have SQL 2008 r2 running on two different servers. The target system processes the millions of records in the queues but will not clean out the sys.conversation_endpoints, or the sys.conversation_endpoints tables.

This is part of the activation proc that is run on the target server.

BEGIN
    BEGIN TRY
        SET NOCOUNT ON;
        DECLARE @RecvReqDlgHandle UNIQUEIDENTIFIER, @RecvReqMsg VARBINARY(MAX), @RecvReqMsgName sysname;

        BEGIN TRANSACTION;
            WAITFOR ( RECEIVE TOP(1) @RecvReqDlgHandle = conversation_handle, @RecvReqMsg = message_body, @RecvReqMsgName = message_type_name
            FROM AccountDataQueue), TIMEOUT 1000;
            IF @RecvReqDlgHandle IS NOT NULL AND @RecvReqMsgName = N’IPGServiceBroker_MT’
            BEGIN
                DECLARE @SBMsgXML XML = CAST(@RecvReqMsg AS XML);
                EXEC SomeDB.dbo.InserRecordSB @SBMsgXML;
            END
            ELSE IF @RecvReqDlgHandle IS NOT NULL AND @RecvReqMsgName = ‘http://schemas.microsoft.com/SQL/ServiceBroker/EndDialog’
            BEGIN
                END CONVERSATION @RecvReqDlgHandle
            END

        COMMIT TRANSACTION;
    END TRY
    BEGIN CATCH
