HI,

We are using two restoring job everyday first restoring job getting  failed the below given error message some time were succeed two job's"Cannot open backup device "backupfile". Operating system error 1265(The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you.). [SQLSTATE 42000] (Error 3201)  RESTORE DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013).  NOTE: The step was retried the requested  number of times (1) without succeeding.  The step failed"

we have restarted the server after that only we are facing the above problem

kindly give solution me tks

first impression, distinct is lighter, rank is more expensive though it is new and cool. likes to see some document explain how each works. execution plan shows  somewhat though.

The story:

I got a query from someone to run on my oracle server(realize the rank is used in SQL server 2012 too), it basically likes to export the number of users who logged in during a month against his database table auditevent(every login has a record),  so count only once if a user logged in more than once.

he is using rank over and count the rank=1 so gives distinct value. his uses 2.697s, I  replaced it with distinct clause which uses 2.60s, the time runs 0.097 second less.  thought it should be much less time used.

where Rank_Line=1

replaced with

I unable to setup a linked server on sql server 2012. The destination server is on sql server 7.0. I can able to setup the same linked server on sql 2005 sp4 and sql 2008 r2 but unable to setup on 2012. I am getting the below error message.

All,

In one of our application, some  errors that are generated are not captured on the database side. For example, errors such as “Cannot insert the value NULL into column '%.*ls', table '%.*ls'; column does not allow nulls. %ls fails.”.  

select*from sys.messageswheremessage_id IN(515,8153)andlanguage_id = 1033

In this example, I was able to force an entry into the SQLServer Error Log by updating the is_event_logged column to 1 (sp_altermessage 515, 'WITH_LOG', 'true';). Like this error, the application might be generating other errors too. I’m aware that one can write an Event Notification process  or Server-Side Trace to capture the error message (and code) via the USER_ERROR_MESSAGE event. But how would I capture the actual code that resulted in the error and email the same?

For example,

CREATETABLE[dbo].[Tab1](

      [Col1][int]NOTNULL,

      [Col2][nvarchar](50)NULL

)

GO

INSERTdbo.Tab1(Col2)values ('test comment')

The insert results in the error

Msg 515, Level 16, State 2, Line 1

Cannot insert the value NULL into column 'Col1', table 'DBAArchive.dbo.Tab1'; column does not allow nulls. INSERT fails.

The statement has been terminated.

I was hoping to use something like EVENT NOTIFICATION services that would capture the error message and the code behind the error message and email these two to the stakeholders. Keen to hear the best practices.

Thanks,

SQL Server 2012 SP 2 on Windows 2012. Yesterday a transaction log backup against the largest database (50 GB database, 5 GB log) failed with the error below. SAN admin tells me everything is fine.

Backup detected log corruption in database SQLMonitor. Context is Bad End Sector. LogFile: 2 'E:\SQLDatabases\SQLMonitor_log.LDF' VLF SeqNo: x236a98 VLFBase: x44630000 LogBlockOffset: x4c47c400 SectorStatus: 4 LogBlock.StartLsn.SeqNo: x236a98 LogBlock.StartLsn.Blk: x3f1eb Size: xf000 PrevSize: xd200

I ran a full backup, changed the recovery model to simple, ran a checkpoint, changed the recovery model back to full, and ran another full backup. Subsequent full and transaction log backups ran fine.

Is there something similar to DBCC CheckDB that I can run to verify the integrity of the transaction log?

Hi Team,

I am facing issue in generating total sum and daily sum from table ThresholdData.

DailyTransactionAmount should be sum of todays amount in the table

TransactionAmount should be sum of all amount in the table.

Basically,

1. I don't want to scan ThresholdData table twice.

2. I don't want to create temporary table/table variable/CTE for this.

3. Is there is any way to make it done in single query.

  I hope, where criteria is not possible in partition function.

I am trying query something as given below,

SELECT  TransactionDate,
  TransactionAmount,
  ROW_NUMBER() over (order by TransactionDate) AS TransactionCount,
  SUM(TransactionAmount) over (partition by id ) AS TransactionAmount, 
  SUM(TransactionAmount) over (partition by id ,CONVERT (DATE, @TodaysTransactionDate)) AS DailyTransactionAmount
 FROM ThresholdData
 WHERE id = @id
 AND transactiondate >= dateadd(d,-@TransactionDaysLimit,@TodaysTransactionDate)

s

If I create a memory table inside a while loop, I expect that every loop the memory table is (newly) created and thus empty.

But when I test this, I see that on the second, third, ... run the inserted data in the memory table is still present and not cleared.

This can be reproduces with the following code:

DECLARE @tbl TABLE
( [id] BIGINT )

DECLARE @tbl2 TABLE
( [value] BIGINT )

INSERT INTO @tbl
VALUES (1), (2)

DECLARE cur CURSOR FOR
  SELECT *
  FROM   @tbl

DECLARE @curid BIGINT

OPEN cur
FETCH next FROM cur INTO @curid

WHILE @@FETCH_STATUS = 0
  BEGIN
      DECLARE @tempcurtable TABLE
      ( [value] BIGINT )

      SELECT 'NOT EMPTY ON MULTIPLE RUNS', *
      FROM   @tempcurtable

      INSERT INTO @tempcurtable
      VALUES (11), (12)

      INSERT INTO @tbl2 (value)
      SELECT value
      FROM   @tempcurtable

      FETCH next FROM cur INTO @curid
  END

/*
	Expectation: twice 11 and 12 in @tbl2
	Actual result: three times 11 and 12
*/
SELECT *
FROM   @tbl2 

Is this a wrong assumption or is this a bug in SQL Server? (Tested on: SQL Server 2014 and 2008).

Can anyone tell me if the following plan works:

1. Setup the new server. Install SQL 2012, move all server objects (logins, databases, jobs, alerts, operators, etc.) to the new server. Keep the user database physical file directory/security same as the old server.
2. Test the new server. While testing the new server, the old server remains as the production server.
3. On the target deploy day, clone the old server user database disk volume, and attach the disk to the new server.
4. The new server (SQL 2012) will detect the database files are in old SQL 2008 R2 format and automatically do the conversion.

My question is should I detach all the testing databases before attach the cloned disk to the new server, and manually attach the user databases after the disk is attached. Or SQL Server can automatically do the conversion as step 4 described.

Thanks,

Folks,

Today we received an issue on an application database on internal free space on the DB is 0% that was designed with as below

name    fileid    filename    filegroup    size    maxsize    growth    usage
XX    1    I:\Data\MSSQL.1\MSSQL\Data\New XX.mdf    PRIMARY    68140032 KB    Unlimited    0 KB    data only
XX_log    2    I:\Data\MSSQL.1\MSSQL\Data\New XX_log.LDF    NULL    1050112 KB    2147483648 KB    102400 KB    log only
XX_2    3    I:\Data\MSSQL.1\MSSQL\Data\New XX_2.ndf    PRIMARY    15458304 KB    Unlimited    0 KB    data only
XX_3    4    I:\Data\MSSQL.1\MSSQL\Data\New XX_3.ndf    PRIMARY    13186048 KB    Unlimited    0 KB    data only
XX_4    5    I:\Data\MSSQL.1\MSSQL\Data\New XX_4.ndf    PRIMARY    19570688 KB    Unlimited    204800 KB    data only
XX_5    6    I:\Data\MSSQL.1\MSSQL\Data\New XX_5.ndf    PRIMARY    19591168 KB    Unlimited    204800 KB    data only

2 of the secondary data files had its autogrowth enabled to unrestricted with 200MB and 3 of the data files including primary had its Autogowth turned OFF. Application use is complaining that there is no internal freespace on the DB.

What fails to understand us is that when the Auto growth was already TURNED OFF on 3 data files ( 1 primary and 2 secondary ) still why was the application trying to increase the space on the .mdf and .ndf files; as well when the Autogrowth is TURNED ON on 2 of the secondary data files, why was the DB not able to expand these file groups when the autogrowth is already turned off on 3 of its  other files.

What more data i need to ensure i submit an analysis to this.

Thanks Eben

Thanks

Hi guys, if I query the sys.objects as

SELECT

TOP22*FROMsys.objectsORDERBYmodify_dateDESC

I retrieve the objectId. Having it how can I retrieve the db that belongs that objectID?

Many Thanks

Hello,

I looked at the number of VLFs in ony databases and figured out it was 300. I looked at the log file and its 40GB with 99% free space. I reduced the log file to 1GB. Now I looked at the VLFs and the count is 250. so 250 vlfs in a 1GB of log file. Is there a way to get the VLFs to a decent number?

Also my transaction log backups run once every 5 mins and auto growth on data and log files is 10MB.

Thanks

Hello everybody!

I'm collecting performance data via DMV to check the buffer hit ratio on several servers. Sometimes I get values high above 100% hit Ratio.

Example (50050%):

SQLServer:Buffer Manager:Buffer cache hit ratio 2002
SQLServer:Buffer Manager:Buffer cache hit ratio base 4

How is that possible?

Cheers!

Hi, I have the below view 

CREATE VIEW vwEmployee
AS
SELECT TOP 1 ID, DateAdded
FROM DB1.dbo.tblEmployee WITH (UPDLOCK, READPAST)
ORDER BY ID ASC, DateAdded ASC

when I run something like 

begin transaction
select * from vwEmployee
waitfor delay '00:00:05'
commit

usually there has to be update lock on only 1 row in the table. But I see Update lock on each row of the table. When I run the same query on the table

select top 1 * FROM DB1.dbo.tblEmployee WITH (UPDLOCK, READPAST)  ORDER BY ID ASC, DateAdded ASC

I see the update lock is only on 1 row. So what I m missing here? Can someone please shed light on this? Thank you

Sorry for cross posting but I thought maybe someone from this group might take a look at this and see what they think...

Hi,

Give a user table ‘MyTable’. How to know whether the table contains a non-unique clustered index by using SQL query?

Thanks

It appears me greyed out, how can I solve that?

I've created few tables already populated and I don't want to delete them and then assign the correct schema.

These tables were created using dbo schema but now I need to assign other schema

I've got one SqlExpress 2008 and happen the same.. How odd! Logged both Sql Server as SA user.

I remember in 2005 version that such option was enable.

am I missing something?

Thanks for any input provided.

Let's say I have a linked server set up with the name MyLinkedServer.

Then I can run a query like this:

-- Query 1
select * from MyLinkedServer.TheirDB.dbo.TheirTable;

But what I really want to do is this:

-- Query 2
select * from MyLinkedServer.TheirDB.dbo.TheirTable
where Updated > DATEADD(MINUTE, -60, GETDATE());

The problem is that GETDATE and DATEADD get run on the local server, not the remote server.  The local server is on the west coast and the linked server is on the east coast.  So, instead of getting 1 hour's worth of data, I get 4 hours' worth of data.

How do I get GETDATE to be evaluated at the remote server?  I figured out that I can accomplish the proper result this way (which is non-atomic and has the performance impact of two cross country trips):

-- Query 3
declare @ts datetime;
select @ts = ts from OPENQUERY(
  MyLinkedServer, N'select [ts] = DATEADD(MINUTE, -60, GETDATE())');
select * from MyLinkedServer.TheirDB.dbo.TheirTable
where Updated > @ts;

Is there any way to write a single statement, something like Query 2, where I can indicate that I want GETDATE andDATEADD evaluated at the remote server?  Please do not post a solution that requires knowledge or computation of the time zone difference between the two servers.  I want to know about forcing remote execution of the system functions.

Hello everyone.

Does anyone knows how to restore database backups with different recovery fork. I have 1-full backup 2-diff backups and 10-tran backups. My prod database in mirror, so after error, switched to mirror with "allow_data_loss" option. And now I have full and diff backup with one recovery fork GUID and other backups with another GUID.

So the question is, how to restore all this backups if in middle of restoration will be different recovery fork.

Tryed to restore log backups with new fork guid and got error:This backup set cannot be applied because it is on a recovery path that is inconsistent with the database. The recovery path is the sequence of data and log backups that have brought the database to a particular recovery point. Find a compatible backup to restore, or restore the rest of the database to match a recovery point within this backup set, which will restore the database to a different point in time. For more information about recovery paths, see SQL Server Books Online.
