MS SQL Server :: Deadlock -select With Exclusive Lock

Exclusive Lock During A SELECT

Aug 9, 2000

Anybody know how a SELECT statement can generate an exclusive lock on a table ?
I always thought that SELECT's take out shared locks. Is this something to do with temporary tables generated by ORDER BY's and DISTINCT ?
Rogue SQL below (from Site Server).

SELECT A.i_Dsid, A.i_Aid, A.vc_Val, A.i_Val, A.dt_Val, A.img_Val FROM Object_Attributes A, ( SELECT DISTINCT L.i_Dsid FROM Object_Lookup L , Object_Attributes OA2 (index = IND_vc_Aid) WHERE ((( L.i_ObjectClass = 9999 )) AND ( OA2.vc_Val LIKE ( '999999999.9999999%' ) AND OA2.i_Aid = 99)) AND (L.i_Container_Dsid = 99) AND ( OA2.i_Dsid = L.i_Dsid )) AS B WHERE B.i_Dsid = A.i_Dsid AND A.i_Aid NOT IN( 1, 2, 3, 4, 5 ) ORDER BY A.i_Dsid, A.i_Aid

Can anybody suggest a workaround ? Thanks.

Error: A Deadlock Was Detected While Trying To Lock Variable X For Read Access. A Lock Could Not Be Acquired After 16 Attempts

Feb 2, 2007

I simply made my script task (or any other task) fail

In my package error handler i have a Exec SQL task - for Stored Proc

SP statement is set in following expression (works fine in design time):

"EXEC [dbo].[us_sp_Insert_STG_FEED_EVENT_LOG] @FEED_ID= " + (DT_WSTR,10) @[User::FEED_ID] + ", @FEED_EVENT_LOG_TYPE_ID = 3, @STARTED_ON = '"+(DT_WSTR,30)@[System::StartTime] +"', @ENDED_ON = NULL, @message = 'Package failed. ErrorCode: "+(DT_WSTR,10)@[System::ErrorCode]+" ErrorMsg: "+@[System::ErrorDescription]+"', @FILES_PROCESSED = '" + @[User::t_ProcessedFiles] + "', @PKG_EXECUTION_ID = '" + @[System::ExecutionInstanceGUID] + "'"

From progress:

Error: The Script returned a failure result.
Task SCR REIL Data failed

OnError - Task SQL Insert Error Msg
Error: A deadlock was detected while trying to lock variable "System::ErrorCode, System::ErrorDescription, System::ExecutionInstanceGUID, System::StartTime, User::FEED_ID, User::t_ProcessedFiles" for read access. A lock could not be acquired after 16 attempts and timed out.

Modify the expression to be valid.

Warning: The Execution method succeeded, but the number of errors raised (4) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.

And how did I get 4 errors? - I only set my script task result to failure

Exclusive Insert Lock On A Table

Sep 10, 2007

Hello All!
I want to perform 4 or 5 statements as a transaction but I need to make sure that during this complete transaction no one else inserts or deletes records from a table named SomeTable.
So how can I lock MyTable at the beggining of the transaction so that during my transaction no one else can insert or delete anything in table SomeTable?
Thanks!

Can You Place An Exclusive Row Lock Using A Hint?

Feb 21, 2000

Hi,

Is it possible to place an exclusive row lock when running a SELECT query by using a lock hint (or otherwise).

Basically, when a select statement is run against a table I don't won't any other users to read that row until it has been updated - at some later stage.

Any suggestions on whether this is possible would be welcome.

Thanks,

Karl

Inserts Resulting In Exclusive Key Lock

Apr 1, 2004

I'm relatively new to SQL and I've come across something that doesn't seem quite right. When an insert becomes part of an transaction I notice an exclusive KEY lock in Enterprise Manager. The table in question was using a Clustered index but I changed that, dropped the table and brought it back in but I still get the lock which keeps all others out of the table. Is this the expected behavior or is there something I am missing? Could the size of the tabe affect things? This is a very small table currently. I'm using MSSQL 7 sp3.

Thanks,
John

Is It Possible To Read Data From A Table With Exclusive Lock ?

Sep 4, 2006

Hello,

We currently use SQL Serv 2000 with an ERP application and VB applications.

Both system work with the same database & tables but the ERP application seems to put exclusive lock on all tables it needs during processes. So our VB applications are not able to read these data and we receive TIMEOUT error.

What can I do ?

thank you

SQL2K: Deadlock On Lock

Sep 10, 2007

Hello,

I have scheduled a job using Job Agent in SQL2K (Management). Every once in a while i get an error when i view job history:

Executed as user: xxx. Transaction (Process ID 53) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction. [SQLSTATE 40001] (Error 1205). The step failed.

The process ID changes for every error. Sometimes its 51, 56, or 54 as well.

I have checked several times, but there is no other process that runs at that time. I even rescheduled it for a different time, but even then it fails about once every week or two.

How can i check what is the other procedure it is deadlocking with, if it is? OR what exactly is the problem, if it is not with any other process?

Any help and/or guidance is much appreciated.

Thanks,

J

Transaction (Process ID 135) Was Deadlocked On Lock Resources With Another Process And Has Been Chosen As The Deadlock Victim.

Nov 14, 2007

Hi,

I was trying to extract data from the source server using OLEDB Source and SQL Server Destination when i encountered this error:

"Transaction (Process ID 135) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.".

What must be done so that even if the table being queried is locked, i wouldn't experience any deadlock?

Deadlock Within Select?

Feb 8, 2006

My SQL Server has kicked out a deadlocked process, which should only berunning a select statement, though there is another select on one ofthe tables in the WHERE clause (see code below). Can anyone tell mewhether this is possible, or is it that my system, which is re-usingconnections, is trying to complete an earlier statement? I've lookedthrough the system and think I'm committing all transactions.The query I'm running (simplified, I don't use daft names like 'table1'or 'date_col', honest :) is:SELECT table1.*, table2.*, table3.*FROM table1, table2, table3WHERE table2.col1 = table1.col1 AND table3.col1 = table1.col2AND table1.col3 = 'xyz'AND (table1.date_col >= '2006-02-01' OR table1.date_col IN(SELECT date_col FROM table1 WHERE (col4 = 'A' OR col4 = 'B') AND col3= 'xyz'))ORDER BY table1.date_colThanksJ

Deadlock On A Select Query, Possible?

Jan 31, 2005

I have a simple select query that selects data from a view. I consistently get a deadlock exception when running this query:

Server: Msg 1205, Level 13, State 2, Line 1
Transaction (Process ID #) was deadlocked on thread | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

The view is a simple select statement that has WITH (NOLOCK) as a hint on all tables. I thought I understand how deadlocks worked, two threads are holding a lock and request the other's item. How does a read uncommitted select statement participate in this?

If I look at the other processes in the current activity and run sql profiler, there is no other activity and no existing locks at the time the statement is run.

Can anyone explain this? Or should I bounce my server and hope it never happens again?

Thanks,

Dave

Deadlock In View With Select Union - Creating A/S Dimension

Jul 23, 2005

I've got a view that creates a parent child relationship, this view isused in Analysis Services to create a dimension in a datastore. Thisquery tends to deadlock after about 10 days of running smoothly. Onlyway to fix it is to reboot the box, I can recycle the services for aquick fix but that usually only works for the next 1-2 times I call theview.This view is used to create a breakdown of the bill-to locations fromContinent-Global Region-Country-Sub Region-State/Province- City-ZipCodeYes, I know that sounds crazy, but it was a requirement.So why would I get a deadlock on a SELECT Query?

SQL Server 2000 Deadlock Concurrent Select Transcations

Oct 14, 2007

There are a series of traces of transactions for essentially the same units of work. Each includes a retrieving the same table "Select" from the database. The first 4 transactions ran concurrently. The last one ran about 7 minutes later with no other concurrent transactions.

The elapsed times for the database accesses for each of the first 4 is significantly higher than the last one.
Can you think of any database optimazation that might improve this?

Are there any utilities available than can be used for stand-alone testing of SQL Server database performance?
E.G. they would measure response time for reading/writing large/small amounts of canned data once/multiple times with concurrent/nonconcurrent access.

SQL Server Database is on 2000.I am not sure about the ISOLATION level in the Java code.

Basically I am new to SQL Sever....Please ans the above questions and provide me the direction to proceed on these questions

Insert Should Aquire Only Exclusive Rowlock. Why Does Insert Block Select With ( Updlock, Rowlock )?

Mar 12, 2007

Here is the situation i am stuck with, see the example first and below explained the problem:

-- 'SESSION A

create table foo (

id integer,

pid integer,

data varchar(10)

);

begin transaction

insert into foo values ( 1, 1, 'foo' )

insert into foo values ( 2, 1, 'bar' )

insert into foo values ( 3, 1, 'bozo' )

insert into foo values ( 4, 2, 'snafu' )

insert into foo values ( 5, 2, 'rimrom' )

insert into foo values ( 6, 2, 'blark' )

insert into foo values ( 7, 3, 'smeg' )

commit transaction

create index foo_id_idx on foo ( id )

create index foo_pid_idx on foo ( pid )

begin transaction

insert into foo values ( 9, 3, 'blamo' )

-- 'SESSION B

begin transaction

select id, data from foo with ( updlock, rowlock ) where id = 5;

-- Problem:

-- Uncommitted transaction in session A, with insert into table FOO, aquires lock on index foo_pid_idx which BLOCKS select with ( updlock, rowlock ) in session B.

-- Insert should aquire only exclusive rowlock. Why does insert block select with ( updlock, rowlock )?

Appreciate your help,

Row Lock Versus Page Lock In SQL 2000.

Apr 7, 2004

Hi
We are facing an acute situation in our web-application. Technology is ASP.NEt/VB.NET, SQL Server 2000.

Consider a scenario in which User 1 is clicking on a button which calls a SQL stored procedure. This procedure selects Group A of records of Database Page1.

At the same time if User 2 also clicks the same button which calls same SQL stored procedure. This procedure selects Group B of records of Database Page1.

So, its the same Page1 but different sets of records. At this moment, both the calls have shared locked on the Page1 inside the procedure.

Now, in call 1, inside the procedure after selecting Group A of records, the next statement is and update to those records. As soon as update statement executes, SQL Server throws a deadlock exception as follows :

Transaction (Process ID 78) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction

We are able to understand why its happening. Its because, Group A and Group B of records are on the same Page1. But both the users have shared lock on the Page1. So, no one gets the exclusive lock in records for update, even though, the records are different.

How can I resolve this issue? How can I get lock on wanted rows instead of entire page?

Please advice. Thanks a bunch.

ERROR: A Variable May Only Be Added Once To Either The Read Lock List Or The Write Lock List.

May 22, 2006

Hi,
I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.

From the parent package-> Execute Process Task->
dtsexec /F etc... /<pkg variable> = "servername"

Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)

I "sometimes" get the following error:

OnError,I4,TESTDOMAdministrator,ACDWAggregation,{A1F8E43F-15F1-4685-8C18-6866AB31E62B},{77B2F3C7-6756-46EB-8C01-D880598FB4B3},5/22/2006 5:10:28 PM,5/22/2006 5:10:28 PM,-1073659822,0x,The variable "User::DWServerSQLInstance" is already on the read list. A variable may only be added once to either the read lock list or the write lock list.

Help would be appreciated!

I have seen other posts on this but, not able to relate the solution to my scenario.

A Variable May Only Be Added Once To Either The Read Lock List Or The Write Lock List

May 10, 2006

Hi All,

I have seen a few other people have this error.

Package works fine when run from BIDS, DTExec, dtexecui. When I schedule it, It get these random errors. (See below)

The main culprit is a variable called "RecordsetFileDIR" which is set using an expression. (@[User::_ROOT] + "RecordSets\")

A number of other variables use this as part of their expression and as they all fail, pretty much everything dies.

I have installed SP1 (Not Beta) on server. Package uses config files to set the value of _ROOT.

The error does not always seem to be with this particular variable though. Always a variable that uses an expression but errors are random. Also, It will run 3 out of 10 times without a problem. I am the only person on the server at the time.

Any ideas?

Cheers,

Crispin

Non-bitwise Exclusive Or?

Jan 30, 2004

Is there a way to do a logical exclusive OR (XOR) in sql server?

I'm trying to do this in where clause, something like:

WHERE
(not exists (select 1 from table a where a.date > '01/30/03') XOR
exists (select 1 from table a where a.date < '01/30/03'))

Thanks!

Many To Many - Exclusive Result

Oct 17, 2007

A problem about many to many relationships from an SQL beginner. Here's a contrived abstract example, as I'd prefer not to give away specifics.

Imagine I have two tables: users, food
The relationship (to like) is many-to-many so I've got a link table, which might look like the below:

andrew, apples
bob, banana
bob, apples
chris, carrots
chris, apples
chris, banana

I want to select users who like bananas and apples exclusively.

The answer should be 'bob' ONLY. select * from users inner join food on <IDs> where food in ('bananas','apples') isn't suitable , because it'll also return 'chris' who should be disqualified (because he also likes carrots).

Apart from potentially being bad DB design (although this is an abstract example; I do have ID numbers), can anyone suggest how to get this in a scalable way?

Trying To Get Exclusive Access To A DB For Restore.

Feb 11, 2004

I have created a SQL Agent job that is supposed to essentially duplicate a production database to another database. The code I am using is:

step1
__________________________________________________ ______
declare @sql varchar(8000)
set @sql=''
select @sql=@sql+'kill '+cast(spid as varchar)+char(13)+char(10)
from sysprocesses where dbid=12

--Print (@SQL)
exec(@sql)

step2
__________________________________________________ ________

RESTORE DATABASE HIWDYNARPT FROM PRDBACKUP
WITH REPLACE
__________________________________________________ ______

This works when I test it during the day, however when it runs at night I get the following error in the job log:

Database in use. The system administrator must have exclusive use of the database to run the restore operation. [SQLSTATE 42000] (Error 3101) Backup or restore operation terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.

I'm not sure why this happens because I have killed all open threads in step 1, and then create my own new thread in step two. Maybe someone else is initiating a new thread to quickly between the steps???

Anyway, I am trying to use:
__________________________________________________ __
ALTER DATABASE HIWDYNARPT
RESTRICTED_USER
WITH ROLLBACK IMMEDIATE
__________________________________________________ ____

...as an alternative to the T-SQL killing PID's, but SQL 7.0 SP4 does not seem to support restricted user like 2000. It keeps giving me a syntax error. Does anyone have any suggestions?

If I bring step 1 and step 2 together, separated by "GO", could this fix the problem?

Thanks in advance!

Exclusive Access Could Not Be Obtained Because The

Dec 8, 2007

Could anybody give a lead as to what I can do get rid off this error please.

I alread tried following:
use master
go
Alter Database dbname set single_user with rollback immediate;
go

Still have the issue. SQL 2005 Server actually did lock the db.
So ran
Alter Database dbname set multi_user;
go
and refresh Query and it switch back to multi user.
But I can't restore db yet.

Thank you
