Deadlock Reason?
Apr 24, 2008
I am having difficulty in identify my deadlock reason. So, please give me some hints.
In my application, I have 2 standard functions. One for transaction creation and one for reporting. The strange problem is I seldom / never got any deadlock witht the transaction creation. Instead, I got deadlock problem with the reporting.
In the reporting function, I only use select and aggregate function. Why will deadlock be raised? Can someone give me an example why such deadlock happened?
Thanks in advance.

Is there a way to send out an email woth deadlock information (victim query, winner query, process id's and resources on which the deadlock occurred) as soon as a deadlock occurs in a database or at instance level?I currently has trace flag 1222 turned on. And also created an alert that send me an email whenever a deadlock occurs. but it just says that a deadlock occurred and I log into sql server error log and review the information.

When I design package under ssis, I always use execute sql task to replace OLE DB Command. Normally, I use staging tables to get all data from data source,then modify or generate some columns on the staging tables according to bussiness rules using execute sql task, Finally,transfer to data destination. And execute sql task is more effiecient than OLE DB Command. I suppose there's reason for using
OLE DB Command. But I don't know. So what's the reason to use OLE DB Command?

Hi,
I have a package that just won't run from a job.
To test the problem, I created a very simple package. All it does is load a simple text file to a table on the local server.
I set protection level to "encrypt sensitive with password", and set the password. I changed the creator name to the SQL Server Agent Account. (don't know how to change the GUID?)
It runs fine from BIDS and msdb storage. But if I run it from the job, it fails with:
Executed as user: DOMAINUSERNAME. The package execution failed. The step failed.
No logging occurs, even though I have set the package to log, which seems to indicate it's not even getting as far as starting the package. I've restarted all the services.
I tried running this package from a job on ANOTHER server and it works, no problem. There's just something going on with this other server where it won't run from the job... both servers use the same SQL Server Agent account.
I've consulted http://support.microsoft.com/kb/918760 and it talks about this problem but I have everything set correctly... never had this problem before... seriously.
HELP

While investigating performance problems within an application recently I carried out some tests using SET SHOWPLAN ON.
I had a query like this within a stored procedure:
SELECT MAX(X) FROM Y WHERE Z LIKE @MYVAR
Where @MYVAR was passed in. I discovered that SQL Server did a Table Scan even when Z had an index on it. A problem with 200,000 rows!
If I said
SELECT MAX(X) FROM Y WHERE Z LIKE 'HELLO%'
(i.e., used a constant instead of a variable) SQL Server did use the index correctly and did not do a table scan.
I got around this by rewriting my statement:
SELECT MAX(X) FROM Y (INDEX=MYINDEX) WHERE Z LIKE @MYVAR
in other words by manually specifying the index I had created on the Z column.
Hope this helps someone.

Dear All,
I have some user databases that go into single user mode
for no apparent reason. Is there any reason that SQL
Server 7 would set a database in single user mode
by itself? NB They are not being set single user by anyone
else here, they would not know how.
Many Thanks in Advance,
Andrew

Hi,
I hava a JAVA application that updates a SQL2000 (SP3a)database.
The application handles different types of "jobs" which effectively update the DB.
One job in particular appears to block all subsequent jobs. It comprises of a large amount of inserts/updates in a single transaction. This is necessary as it is an "all or nothing" scenario - so we cannot break the transaction into smaller ones. The transaction appears to succeed as it reaches the COMMIT TRAN statement without error.
However the records do not get written to the database.
EM indicates a large number of locks held on the tables accessed by the transaction and these do not get released.
Using the SP sp_blocker_pss80, the blocking SPID has a waittime of 0 and a waittype of 0x0000 - the lastwaittype is WRITELOG and its status is AWAITING COMMAND
I am using MS SQLSERVER JDBC Driver SP2 (considering using jTDS)
I have tried
- increasing Transaction Log size
- Moving Transaction Log to a separate Disk
- Reducing Isolation Mode to Read Uncommitted
- Set AutoCOMMIT to true
- set Close Cursor on COMMIT
- set SelectMethod to Direct - (we use Cursor by default)
None of these have succeeded in fixing the issue.
The job will succeed if it is the first/only job to access the database.
But if another job precedes it - then the blocking occurs.
I have verified that the preceding job only holds shared dataabase locks
before the blocking job is run.
Each job will use its own JDBC connections to access the database for reading
purposes, but all of the writing goes through the blocking SPID.
Any ideas?
Thanks, Liam

...and it is because...
when i drag and drop my script file into query window unlike query analyzer which selects the current database, new MSSMS selects the users 'default' database.
we maintain 1 script file for each sp/function and ddl/views groupe related stuff in 1 or more files
in query analyzer I just have to select DB where i want to deploy scripts and drag and drop the files from explorer and then then
1) press F5 (to run)
2) press CTL + F4 (to close window)
3) repeat till all scripts are deployed
and now in MSSMS
1) select db (this step is really painful especially when i have to deploy more than 1 script/file)
2) press F5
3) press CTL + F4
4) repeat
is there any settings that could change the behavior of SMS2K5 like old QA2K?
well what i cant do here is change default db to the tartget db before deploying and switch back after deploying (but not a true solution)
thanks in advance

Hi,
I have a package that has several FTP tasks in sequence:
[ftp task 1]->[ftp task 2]->[ftp task 3]->[ftp task 4]
[Ftp task 4] fails about 20% of the time, for no apparent reason. This is the error message I receive:
[FTP Task] Error: Unable to receive files using "FTP Connection Manager".
The problem is, it works most of the time (80%), but every 4 or 5 tries, it fails. This makes NO sense to me. Is this a bug perhaps?
Please help... should we use an ftp script instead, as the ftp task seems rather unreliable.
Thanks

I can backup this key using something like:

ENCRYPTION BY PASSWORD = '23'
but why would I need to do it as the DBMK is stored in the databases itself ( in sys.symmetric_keys) and we dump all databases nightly. Just "in case"?
TIA,

I have been working on an app for several weeks. My database size went from 9MB to about 12MB. Sometime in the last 2 days it jumped up to 242 MB. I don't know why. Now I cannot open it with management Studio Express. It says another process is using it. Usually this means I have a aspnet_wp.exe process running (from Visual Studio) and I just end the process, but Wndows Task Manager will not end the process. It does knock its size way down to 2.9 MB but won't kill it. Rebooting won't kill it either.Are these two symptoms related? How do I recover?Thank you.

Hello, I am having problems inserting information into my DB.
First is the code for the insert
Sub AddCollector(Sender As Object, E As EventArgs)
Message.InnerHtml = ""
If (Page.IsValid)
Dim ConnectionString As String = "server='(local)'; trusted_connection=true; database='MyCollection'"
Dim myConnection As New SqlConnection(ConnectionString)
Dim myCommand As SqlCommand
Dim InsertCmd As String = "insert into Collectors (CollectorID, Name, EmailAddress, Password, Information) values (@CollectorID, @Name, @Email, @Password, @Information)"
myCommand = New SqlCommand(InsertCmd, myConnection)
myCommand.Connection.Open()
myCommand.Parameters.Add(New SqlParameter("@CollectorID", SqlDbType.NVarChar, 50))
myCommand.Parameters("@CollectorID").Value = CollectorID.Text
myCommand.Parameters.Add(New SqlParameter("@Name", SqlDbType.NVarChar, 50))
myCommand.Parameters("@Name").Value = Name.Text
myCommand.Parameters.Add(New SqlParameter("@Email", SqlDbType.NVarChar, 50))
myCommand.Parameters("@Email").Value = EmailAddress.Text
myCommand.Parameters.Add(New SqlParameter("@Password", SqlDbType.NVarChar, 50))
myCommand.Parameters("@Password").Value = Password.Text
myCommand.Parameters.Add(New SqlParameter("@Information", SqlDbType.NVarChar, 3000))
myCommand.Parameters("@Information").Value = Information.Text
Try
myCommand.ExecuteNonQuery()
Message.InnerHtml = "Record Added<br>"
Catch Exp As SQLException
If Exp.Number = 2627
Message.InnerHtml = "ERROR: A record already exists with the same primary key"
Else
Message.InnerHtml = "ERROR: Could not add record"
End If
Message.Style("color") = "red"
End Try
myCommand.Connection.Close()
End If
End Sub
No matter what I get a "Could not add record" message
Even substituting the insert command string with my stored procedure I would get the same thing
Stored Procedure:
CREATE Procedure CollectorAdd
(
@Name nvarchar(50),
@Email nvarchar(50),
@Password nvarchar(50),
@Information nvarchar(3000),
@CustomerID int OUTPUT
)
AS
INSERT Collectors
(
Name,
EMailAddress,
Password,
Information
)
VALUES
(
@Name,
@Email,
@Password,
@Information
)
GO
Can anyone see any problems with this code? It looks good to me but I get the same message always.
Thanks

Does any one know what could be making the size of a backup get so big in SQL server?
I noticed if you back-up the same database in Enterprise Manager over and over (without making any changes to the database), the size of the backup gets bigger and bigger. To get around this I simply erase the backup and create a new one.
Now I'm experiencing the same kind of problem, different situation. I decided to make very few changes to my database. If anything, I shrunk the size of the tables and stored procedures.... Now all of a sudden my database backup is 7 times larger.
What could be increasing the size so much, if I haven't increased the amount of tables or stored procedures?
What is the log file about? Mine is huge? Is there a way to reset it or clear it?
any help would be great.
Thank you,
Alec

Hope someone can help me with this because its driving me potty!
I have a .NET script that sends really simple queries to SQL server that works perfectly 50% of the time but for the other 50% it takes ages (2-3 minutes) and then fails, I'm assuming because it times out. I then check the SQL by excecuting it via query analyzer and it again takes ages but will work eventually (I'm assuming because this bypasses the timeout settings, but changing these isn't on).
This happens randomly, the scripts will be working fine and then fail a few times before magically working again!
Any ideas? Perhaps some database features that commonly cause this problem? The problem only occurs with one database, all our others are fine but we can't spot any differences!
Any help or tips would really be appreciated.
Thanks.

In the master database for a SQL Server instance I noticed the dt... objects (procedures, etc.) in create date of today about 7 minutes before I looked in sysobjects. No changes have been made to that instance for months. Also in other cases I noticed the same thing just different dates for each instance. Any ideas on why the dates would change?

Hi all, could someone be kind enough to provide me some help into why the following IF statement is not working? Basically, I am trying to find out whether a field in my database has a CONSTRAINT attached to it with a particular name... IF it does have one then drop it and re-create it ELSE simply create one.
I have used SELECT * FROM SYSOBJECTS to find whether it exists which according to the results it does EXIST, however my IF statement is not detecting it and I get an error which states:
Msg 1781, Level 16, State 1, Line 30Column already has a DEFAULT bound to it.Msg 1750, Level 16, State 0, Line 30Could not create constraint. See previous errors.
However, surely my IF statement is suppose to be handling this problem and therefore if it does EXIST THEN it should ideally drop the CONSTRAINT and then re-create it but this is not the case... instead the ELSE is always being triggered. After using SYSOBJECTS I copied it directly from the results view into my SQL but still for some reason if my constraint does exist it jumps to the ELSE.
Code SnippetIF EXISTS (SELECT * FROM SYSOBJECTS WHERE NAME = '[DF_TBL_SyncTable_OB-DEVUK]')
BEGIN
ALTER TABLE TBL_SyncTable DROP CONSTRAINT [DF_TBL_SyncTable_OB-DEVUK]
ALTER TABLE TBL_SyncTable ADD CONSTRAINT [DF_TBL_SyncTable_OB-DEVUK] DEFAULT 2 FOR [OB-DEVUK]
ALTER TABLE TBL_SyncTable ADD [OB-DEV6] TINYINT DEFAULT 2
END
ELSE BEGIN ALTER TABLE TBL_SyncTable ADD CONSTRAINT [DF_TBL_SyncTable_OB-DEVUK] DEFAULT 2 FOR [OB-DEVUK]
ALTER TABLE TBL_SyncTable ADD [OB-DEV6] TINYINT DEFAULT 2
END
Thanks for replies + suggestions + comments

I have a job that runs an SSIS package. The job seems to be able to run through the package successfully, but at the end it errors out saying "The binary code for the script is not found. ...". The script referred to is at the beginning part (not the very first step) and should already be run.
The thing is, I can manually run this package on the server or visual studio without any problem. Also this job has been run on a regular basis without any issues on our old SQL 2008. I'm migrating this to Amazon Cloud SQL 2014.
Together with this package are other two very similar ones. They all work fine. I just can't figure out what can be wrong with this one.

I have searched extensively and not been able to find a solution to this problem.
The problem:
We have one SSIS package will sometimes 'finish' executing (or crash from a .NET exception) when it certainly has not made its way through all of the data flow components. There are no SSIS error messages, no warnings, and it never happens at the same location in the package's pipeline. The only thing that is instantly visible is a command window that flashes on the screen and disappears too quickly to see anything,.
Sometimes the package does actually complete without any problem, but most of the time, it does not.
What we see:
If the packages is being run through the "Execute Package Utility" (by double clicking the dtsx file), after a bit, a command window flashes on the screen and instantly disappears (no text is visible), then the €œExecute Package Utility€? disappears. The event viewer of the machine then shows:
Source: .NET Runtime 2.0 Error
Category: None
Event ID: 1000
Type: Error
Description: Faulting application dtexecui.exe, version 9.0.3042.0, stamp 45cd726d, faulting module dtspipeline.dll, version 2005.90.3042.0, stamp 45cd721f, debug? 0, fault address 0x00019a66.
If the package is running within visual studio, again the command window flashes on the screen, then the "Execution has completed" prompt appears, but any "running" component remains Yellow (no red), both within the data flow and control flow (we do not have any event handlers set up). Neither our SQL Log provider, nor the "Execution Results" tab in visual studio show any type of error message... all SSIS messages just stop right in the middle of the many OnPipelineRowsSent log events (so there is no PackageEnd log event when this happens). The event viewer on the machine contains no useful messages when running within visual studio.
And other packages:
Are fine. This is only the case for this one package... we have nearly a dozen other packages, all very similar in design, that complete without issue.
We have also tried re-creating this troublesome package from scratch with no avail.
<!--[if !supportLineBreakNewLine]-->
About the package:
The Data Flow is pulling rows from 3 different external SQL data sources (400k-500k rows total), sorting and merging the rows, performing some basic lookups, then SCD'ing the results. This Data Flow is executed multiple times within 2 nested for loops (these nested loops give us particular dates, i.e. years 2000 through 2008, then months 1 through 12 for each year). There is not a single script task in the package. The problem seems to happen most as the data is being pulled from the sources and merged together, but it is not limited to this area.
<!--[if !supportLineBreakNewLine]--><!--[endif]-->
The environment:
We€™ve tried to use multiple machines with the same result. The current machine specs are as follows:
SQL Server 9.0.3042 (SP2)
Windows Server 2003 R2, Enterprise x64 Edition, SP2
3.00GHz x 16 processors, all 64 bit
63.5 GB of RAM
Over 1 terabyte of hard disk space
.NET 2.0.50727.42
The package was designed using:
Visual Studio 2005 with SP1
Microsoft SQL Server Integration Services Designer - Version 9.00.3042.00
Anyone have an idea? Thanks in advance.
