Query over linked server responds with partial data when the spid on the remote server is killed

August 27, 2013, 10:51 am

Local server is version 10.50.4000
Linked server is 9.0.5000

With the following stored procedure:
Create table #TMP
    (
        [ID] int NOT NULL,
        [SKU] [varchar](50) NOT NULL,
        ...
    )
    INSERT INTO #TMP
    SELECT
        [Siteid]
     ,[ITEM]
    
    FROM LinkedServer.db.dbo.v_ViewOnLinkedServer WITH (NOLOCK)
    
    PRINT 'Inserted'
    
    DELETE LocalTable
    WHERE SKU NOT IN (SELECT SKU FROM #TMP)

The spid on the remote server was killed and the query inserted into the temp table just a third of the records - causing the other 2 thirds to be deleted

What was expected:
The cross sever query should have been an Atomic operation - if part of it failed then all of it should have failed.

We ran many tests over and over (20 +) and got variable results - 

most times it retrieves thousands of rows then failed cleanly when the spid was killed.

however about 5% of the time  the query returned as if it had read all of its results and continued on with the next stamtet as if nothing happend

Running SQL 2008 R2 but server showing up as sql 2005 (9.0.4035)

August 27, 2013, 2:09 pm

I have installed and run 2008 R2 for some time--no problems. use as backend for VS2008 code

recently I tried to restore one of my developer databases with a backup from a production server running 2008.

gave me error messages about incompatible media family--tracked down that problem and discovered that even though I installed and thought I was running 2008 on my developer box, @@version gives 9.0.4035.  but 2008 R2 is installed and management studio gives version 10.50.1617.

now I need to import data from the 2008 to what I thought was my 2008 but is really 2005.  I tried scripting but HUGE file.  until I can get some free time to uninstall and try to install sql 2008 again, any ideas for a temp work around. 

is there a way to upgrade this 2005 instance inside of my 2008 installation to 2008 structure. can this thing happen or did I have a bad installation. only thinig I can think of is that in the past I might have backed up a 2005 database from another machine and restored it here but not sure how that could result in this.

another theory-when I installed Visual Studio 2008, it might have installed 2005 SQL Express.  then I installed SQL 2008.  probably should have done it the other way around, i'm thinking

any advice is appreciated

thanks

Update PDF file in FileTable

August 17, 2013, 1:11 pm

Hi-
I'm new to working with FileTables and am wondering if the following code (which saves annotations to a PDF file in the FileTable with changes that are made through the PDF control) makes sense. My save results are mixed while using the PDF control, depending upon the PDF file that is loaded. If a save is successful, the PDF control will load the PDF file with the annoatations, but the PDF file will not open in Adobe Acrobat (file corruption error is reported).

When using the provided PDFTron sample PDF control project with a file loaded from the file system, no errors are reported when saving annotations to the PDF file, and the changes can be viewed using Adobe Acrobat.

I'm wondering whether my code is generally appropriate, or if I'm going about this all wrong.

        'Create a connection to the database
        Dim ConStr As String
        ConStr = MyAppConnString
        Dim con As New SqlConnection(ConStr)
        con.Open()

        Dim sqlCommand As New SqlCommand()

        ' Set Command text to stored procedure name
        With sqlCommand
            sqlCommand.Parameters.Clear()
            .CommandText = "RetrieveDocument"
            ' Set the command type to Stored procedure
            .CommandType = CommandType.StoredProcedure
            ' Add parameter/s to the command. Depends on the Stored procedure
            .Parameters.Add("@SelectedNode", SqlDbType.NVarChar, 128).Value = myTag
            'add the conection to the command
            .Connection = con
        End With

        Dim filePath As String = CStr(sqlCommand.ExecuteScalar())

        'Obtain a Transaction Context
        Dim transaction As SqlTransaction = con.BeginTransaction("ItemTran")
        sqlCommand.Transaction = transaction

        ' Set Command text to stored procedure name
        With sqlCommand
            sqlCommand.Parameters.Clear()
            .CommandText = "tContext"
            ' Set the command type to Stored procedure
            .CommandType = CommandType.StoredProcedure
            .Connection = con
        End With

        Dim txContext As Byte() = CType(sqlCommand.ExecuteScalar(), Byte())

        'Open and read file using SqlFileStream Class
        Dim sqlFileStream As New SqlTypes.SqlFileStream(filePath, txContext, FileAccess.ReadWrite)
        Dim buffer As Byte() = New Byte(CInt(sqlFileStream.Length)) {}

        'Bind the image data to an image control
        Dim ms As MemoryStream = New MemoryStream(buffer)

        _pdfdoc.Lock()
        Try
            _pdfdoc.Save(ms, SDF.SDFDoc.SaveOptions.e_incremental)
        Catch ex As Exception
            MessageBox.Show(ex.ToString(), "Error during the Save")
        End Try
        _pdfdoc.Unlock()

        sqlFileStream.Write(buffer, 0, buffer.Length)

        'Cleanup
        sqlFileStream.Close()
        sqlCommand.Transaction.Commit()
        con.Close()

Thank you,

Issues with reporting percent log space used, between DMV and DBCC

Using SQL Server 2012 SE 11.0.2100, I am getting two different sets of values when querying for log space between the DMV and the DBCC command. 

Querying using the DMV.

select instance_name as DBName, cntr_value as PercentLogUsed from sys.dm_os_performance_counters where counter_name = 'Percent Log Used' and instance_name <> '_Total' and instance_name <> 'mssqlsystemresource' and instance_name <> 'model' order by cntr_value desc

The results that I get from using this DMV are about 10% off from the results that I get when I use dbcc.

DBCC SQLPERF(logspace)

Why is this?

User cannot access database over VPN - database not accessible - sql authentication SSMS

I haven't been able to find this scenario or a solution from searching.  Any help is greatly appreciated.

Using Sql Server Management Studio, I can connect to the database engine. 

Inside the office -- I can see the list of all the database instances.  When I try to expand any of the instances, I can connect to the database and see all the items I have access to, like Tables.

Outside the office over VPN -- I can see the instances, but I cannot connect to it.  I receive the usual error: 

The database [fill in the database name here] is not accessible. (ObjectExplorer)

If I look at the details of the error, it has this:

The database [instance name] is not accessible. (ObjectExplorer)

------------------------------
Program Location:

   at Microsoft.SqlServer.Management.UI.VSIntegration.ObjectExplorer.DatabaseNavigableItem.get_CanGetChildren()
   at Microsoft.SqlServer.Management.UI.VSIntegration.ObjectExplorer.NavigableItem.GetChildren(IGetChildrenRequest request)
   at Microsoft.SqlServer.Management.UI.VSIntegration.ObjectExplorer.ExplorerHierarchyNode.BuildChildren(WaitHandle quitEvent)

If I disconnect from the database engine, then reconnect with other user credentials, I can access everything.

In summary:  the same user can access within the offce, but not over VPN;  I can use a different user and access both ways just fine.

I can see the server properties and configurations and the permissions for the user I'm trying to use.  CONNECT SQL and VIEW ANY DATABASE are effective.

What may be wrong here?

Unable to connect from SQL server 2008(Sp2) version client to SQL Server2012(SP1)

August 28, 2013, 5:46 pm

Our requirement is to connect to dtatabse server from .net application sitting on application server to invoke and run the sql agent job in database server.

But there is different version of SQL server installed on both the application and databse server.

Database server(sql server 2012) is higher version of sql server than the application server(sql server 2008)

We have two servers:

1) Application server- with SQL server 2008(SP2) where our client window application will be running.

2) Database server- with SQL server 2012(SP1) where our sql agent job will be running .

The application server cannot be upgraded to new version of sql server as presently the client application will not support the latter version of sql server. It is compatible only with SQL server 2008(SP2) version.

when we tried to connect to database server from application server using managemet studio it gives the message "Index was out of bounds of array(microsoft.sqlserver.smo)", but still it allows me to connect to database server instance and run our job using the sp_start_job <'job_name'>

From our client windows application which sits on application server(with sql server 2008) we try to connect to database server using connection string in .net code and tries to execute the job sitting on the databse server(sql server 2012) by calling the same sp in .net code, but the log file gives connection error, and hence application is not allowed to establish connection to databse server with Microsoft sql Client 10.0.

Please assist on the above issue.

Shrinkfile exhausting space in transaction log for relatively small amount of data and can't figure out why?

I have multiple file database where the ndf file 9  is 134g in size but 122g of it is free due to a massive amount of table deletions of histrical tables.   The last 12g is most recently created tables  and I have a  two copies of this database.    I have tried running the SQL SERVER Managment Studio  menus and telling it to reorganize the pages  looking to move the 12g to the front of the file and it the shrink failed  because it filled up a 49g transaction log file.     On the second copy of the database I used the command DBCC (9,1)  to shrink the file in a query window.   On this instance the log was only 25g in size but I had done some testing on experimental databases of large allocations where huge amounts of data was deleted and only 12g left at the end and it barely touched the transaction log file so I thought I was safe.   Again I exhausted the transaction log file.   I am baffled as to why this operation is hitting the transaction log file so hard and  if I have to make a large transaction log file, just how large must it be?

Cursor and Memory?

August 29, 2013, 1:05 am
$

I have a strange issue,

When I create a cursor to go and do some work on all my DBs, sometimes it does the work only for the first few and then stops with no output.

i.e. I have a job that runs a cursor on all my DBs and does a reindex on each of them, using a script I wrote for determining which reindex options should be used for each table.

I have very big DBs (all together 5TB), and the number of DBs are dozens.

If I replace the inner script of the cursor with a print of the DB name or any other light process, it runs on all the DBs, but when running it on a heavy job, will stop in the middle.

The above cursor runs as a step in a job (inside a maintenance plan by SSIS).

Today I was searching for a string in all my tables all over the server, so I created a dynamic script to select top 1 where column like ‘%string%’ on all my tables , and it ran only a few of them, the above was ran from the SSMS query window. So I copied the script again on the same window (meaning still on the same session) and had first cursor running on all DBs where the name < I and then again created the same cursor (same name) for all DBs where name > I and it completed the work.

I assume it is something to do with memory or other resource.

Do you know what can I do to have it run over all the DBs in the same cursor?
