On one of my SQL 2012 servers I see this wait type is responsible for very high waits - often as high as 60% of the wall clock time. What exactly does it represent? I can find no documentation on it anywhere.

Full SQL version is 11.0.3513. That's 2012 SP1 with security KB 3045317 applied.

Hi, 

We have all our SQL servers registered in "Central Management Servers" (CMS) in an instance that is due to be decommissioned.   What would the simplest way of moving this CMS to a new instance, is there any way of doing this so that users are unaware and don't have to do anything? It took a while to get people using this central repository and any "inconvenience" and they will be back using their own registered servers. 

Also, as I understand it users need to be members of the ServerGroupReaderRole (msdb) role in order to access this CMS.  This is a bit of a pain and I would like anyone who has SSMS installed to have this role/right by default, what's the simplest way to do this? 

Any suggestions? 

Thanks 

Hello,

We upgraded a dev database from sql server 2012 sp2 to 2014 (o/s is Windows 2008r2 sp1).  We are seeing bazillions of recompiles which kill our memory, and the related semaphore waits.  Apparently something changed with regard to variables in 2014?  Is there a fix for this?

Hi there,

On our newly configured SQL Server Windows NT 64 bit - very high memory usage show up.
We have to reboot it to get it to normal (like to 10% RAM) - RAM usage grows continuously - and in about 18 hours it reaches 95% and our website slows down by a great margin. We reboot the server to get it back to normal and so on.

During such outage I ran ---- Select * from sys.dm_exec_requests ----- and result is here.

If I can provide any more information please let me know.

Thanks so much for help.

Hi,

we have a reporting job that will query the mainDB and do so come calculation and insert into reportingDB, there are a lot of blocking and performance issue when it query  the mainDB so we have plan to read the secondary replica and do the processing there later to insert back into primaryDB (reportingDB).. for this we have implemented linked server but it gets  timeout, I do not want to change the remote query timeout on server level so is there anyway to do this,

Any one making use of secondary replica to do get the data by job?

Thanks

Hello Experts,

I am trying to shrink the log file as it is eating my disk space. increased to 100GB.

I am trying with below queries but no luck. could you please suggest me on this.

message after running the query

"Cannot shrink log file 2 (mydatabase_log) because the logical log file located at the end of the file is in use.

(1 row(s) affected)

Hi,

I have a question relating to the ANSI_PADDING setting on some existing tables in a SQL Server 2008 R2 database I am working with.

When I generated the tables originally I basically programmatically created them by building CREATE scripts within my code. Since I did not explicitly set ANSI_PADDING to ON all these tables they seem to have been created with ANSI_PADDING as OFF. Some of these tables, which I now need to add columns to, contain varchar(n) and varbinary(n) columns. When I try to alter the tables through Management Studio, SQL Server gives me a warning: "One or more tables have ANSI_PADDING 'off' and will be recreated with ANSI_PADDING 'on'" - this seems to be generated by the ALTER statement which by default sets ANSI_PADDING to ON. Another iteration of the same warning - "Columns have different ANSI_PADDING settings. New columns will be created with ANSI_PADDING 'on'".

From what I read regarding ANSI_PADDING it seems ON is definitely the way to go.

I just need to know if changing the value may result in any of the existing data in the table to be changed or may have any other unintended side effect, as this may cause problems for me.

i have 3 tables:

 TABLE [dbo].[Tbl_Products](
[Product_ID] [int] IDENTITY(1,1) NOT NULL,
[Product_Name] [nvarchar](50) NOT NULL,
[Catagory_ID] [int] NOT NULL,
[Entry_Date] [date] NOT NULL,
[User_ID] [int] NULL,
[Barcode_Line] [nvarchar](max) NULL

======================

 TABLE [dbo].[Tbl_PurchaseHeader](
[purchaseOrder] [int] NOT NULL,
[ProductId] [int] NOT NULL,
[SupplierId] [int] NOT NULL,
[CatagoryId] [int] NOT NULL,
[StockId] [int] NOT NULL

=======================

TABLE [dbo].[Tbl_PurchaseDetails](
[PurchaseOrder] [int] NOT NULL,
[BuyPrice] [numeric](18, 3) NOT NULL,
[SellPrice] [numeric](18, 3) NOT NULL,
[TotalPrice] [numeric](18, 3) NOT NULL,
[AllPieces] [int] NOT NULL,
[AllPieceBoxes] [int] NOT NULL,
[BoxesNo] [int] NOT NULL,
[BoxBuyPrice] [numeric](18, 3) NOT NULL,
[BoxSellPrice] [numeric](18, 3) NOT NULL,
[PiecesInBox] [int] NOT NULL,
[BuyDate] [datetime] NOT NULL

=============================

am using this query to get ( Product name from tbl_products , Buy Price - Total Price- Total Quantity from Tbl_Details )

but am getting a multiple result if the order purchase has more than 1 item :

SELECT DISTINCT B.Product_Name,A.AllPieceBoxes,
A.BuyPrice,A.TotalPrice,A.BuyPrice
FROM
Tbl_Products B INNER JOIN Tbl_PurchaseHeader C
ON C.ProductId=B.Product_ID INNER JOIN Tbl_PurchaseDetails A
ON A.PurchaseOrder=C.purchaseOrder
WHERE A.PurchaseOrder=3

Hi,

I'm trying to use the Tasks/Copy Database function to create a copy of quite a large (by our standards, at least) database. the copy runs OK for a while and then fails with the following error in the log:

Update Statistics with Fullscan, does it cause Blocking / Locking?

Can we do this while a series of 50 million inserts are running on the table, is the real question.

After a sudden growth of the TEMPDB data file to approximately 66 GB on production environment i have followed the second method available on MS KB (Method 2: Use the DBCC SHRINKDATABASE command) :

https://support.microsoft.com/en-us/kb/307487

However, after issuing the below script to shrink the file it didn't work and the file remains not shrink with the same 66 GB although the used space of the file now is  220 MB and free space is about 65 GB:

use tempdb
   go

   dbcc shrinkfile (tempdev, 'target size in MB')
   go
   -- this command shrinks the primary data file

   dbcc shrinkfile (templog, 'target size in MB')
   go

Is there any required actions to be applied prior to running the DBCC SHRINKFILE script ?

Update  :

When we try the SHRINKDATABASE option , one of the temp db files got shrink while the other showed the following message:

DBCC SHRINKDATABASE: Page 1:8477818 could not be moved because it is a work table page.

Our production database server is running SQL Server 2012 v11.0.5613.0 (CU6 + MS15-058). Every couple of months, one of our queries gets into a weird state where it stops returning results. I think this is a problem with the query optimizer -- either a bug with the optimizer, or an issue with how it is optimizing the query as-written. I could use some assistance is figuring out which it is, and if there are any workarounds.

While I have a live repro in our production DB right now, I don't have any exact steps for creating an isolated repro. However I'm happy to provide whatever information or traces I can to figure out what's going on.

The query looks roughly like this (in structure, actual names are removed/renamed for readability):

SELECT	COUNT(Field2) AS Rows,
	COUNT(DISTINCT Field) AS Names,
	COUNT(Field2) AS Reviews
FROM( SELECT  * FROM (
	SELECT 	W.Field,
		[... more named fields...]
		C.Field2,
		[... more named fields...]
	FROM (SELECT * FROM vwContent (nolock) WHERE iPublication=@iPublication) C
	INNER JOIN fn (NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL) W
		ON C.Field = W.Field
	INNER JOIN (
		SELECT [KEY] AS Field
		FROM CONTAINSTABLE(tbData, Search, @szSearch)
	) K	ON W.Field = K.Field
)inn
) summary

I find that if I add an OPTION (MAXDOP 1) at the end of the query, then it returns the correct results. Otherwise, it just returns 0 as the count, once the DB gets into this state. If we restart SQL Server, then it does start working, at least for a little while.

Does this sound like any currently known issue with 2012?

I have a large terabyte database with about three tables north of 25 GB in size. The database has an extremely high amount of write transactions happening throughout the day. The tables are heavily fragmented. When I attempt an online index rebuild, there is enough intermittent blocking to cause an outage of the associated application. In addition, the machine's CPU and disk latency skyrockets.

Anyone have any suggestions in how to approach?

 Hi

I have a database of 7 TB,  and I normally use sys.dm_exec_requests to track the progress and to understand estimated time to completion of backup. Backup progress is showing 100% but still process is writing to file even after completion of 100%, I would like to understand what it is writing to backup file.

Thanks & Regards

Hi Folks,

Here is a little script that should produce the very last datetime value in the month for a given datetime value.

CREATE FUNCTION [dbo].[fnLastDayOfMonth]
	(
	@DATE datetime   -- Parameter: (2015-12-10 00:00:00.000)
	)
	RETURNS datetime
	BEGIN
		DECLARE @Result					datetime
		DECLARE @Result1			datetime
		DECLARE @Result2			datetime

		--Jump to next month
		SET @Result = DateAdd(m,1,@date)
		--Result here: (2016-01-10 00:00:00.000) OK
		--set to 1st of next month
		SET @Result = Convert(nvarchar(4),Year(@Result)) + Right('0' + Convert(nvarchar(4),Month(@Result)),2) + '01'
		--Result here: (2016-01-01 00:00:00.000) OK
		--subtract 1 ms
		SET @Result1 = DateAdd(ms,-1,@Result)
		SET @Result2 = DateAdd(ms,-2,@Result)
		RETURN @Result1
		--Result here (2016-01-01 00:00:00.000) Should be (2015-12-31 23:59:59.999)
		RETURN @Result2
		--Result here (2015-12-31 23:59:59.997) Should be (2015-12-31 23:59:59.998)
	END

	--SELECT [dbo].[fnLastDayOfMonth]('2015-12-10 00:00:00.000')

If You run the SELECT at the bottom of the script you get the results i have stated in the comments  (of course, to get @Result2 you have to comment the lineRETURN @Result1).

It looks like there is no way to get to 2015-12-31 23:59:59.999

The same happens when I use datetime2.

Can anyone give me a reason for this behaviour (I'm using 2008R2)
Thanks for your help

It's no problem, it's just the syntax
