Exclusive Access Could Not Be Obtained Because The Database Is In Use.

Jun 15, 2007

I have a test database that is automatically restored from the live database each day at 2:30AM. I recently started receiving this message:

Exclusive access could not be obtained because the database is in use.

and the restore is not able to occur.

Any ideas on how I can prevent this from happening?

Exclusive Access Could Not Be Obtained Because The Database Is In Use

May 31, 2008

Hi!

We're using a backup with sql server agent when doing a backup / restore
procedure. In some cases I get the following error when the restore job
fails:

Executed as user: DOMAINAdministrator. Exclusive access could not be
obtained because the database is in use. [SQLSTATE 42000] (Error 3101)
RESTORE DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013).
The step failed.

Is it related to unhandled lock? I've resolved this by restarting the sql
server. But is there a way to avoid such issues?
One more question. Is it OK to backup/restore database while there're users
connected? Or I can do only backup?

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

I alread tried following:

Cant Restore SQL Server Databases: Exclusive Access Could Not Be Obtained

Jul 7, 2007



Hi everyone,



Hope somebody can help me on this.



I did a full BACKUP for two SQL databases using SQL Server Managament Studio. When trying to RESTORE the DBs, I get the following error:



"System.Data.SqlClient.SqlError: Exclusive access could not be obtained because the database is in use. (Microsoft.SqlServer.Smo)"



There are NO users using the application. These are DBs for the Portfolio Server 2007 application.



After exploring a little bit, I found that there are several "SLEEPING" processes with an "AWATING COMMAND" flag. The processes come from the Portfolio Server Application, maybe from previous sessions.



Can they be deleted? if so, would there be any serious consequences?



Thank you for your help on this.

More On Restoring Database In User Instance - Exclusive Use Not Obtained

Apr 11, 2007



Hi all. I have read and implemented the very helpful threads on backing up and restoring with user instance posted with MFriedlander. Thank you. However, during the rs.SqlRestore(srv) command I am getting the following error "Restore failed for Server '\.pipe4A1F91FF-F6FE-45 sqlquery'. "
"Exclusive access could not be obtained because the database is in use."

I have implemented the changedatabase method as described in that thread.

SqlConnection.ChangeDatabase("master")

right before the line

rs.SqlRestore(srv)

I do not use the default instance of sql express, but I do use an instance called 'test' for my app. Should my changedatabase method also refer to my sql instance?

I am running from VS 2005 debug (F5) when it fails and cannot think of anything that would be locking it. Any help would be appreciated. Thank you. Below is the full code of the restore.

Robert



Dim sqlconnection As SqlConnection = New SqlConnection(My.Settings.dbTestConnectionString)

sqlconnection.Open()

MsgBox(sqlconnection.Database.ToString())

Dim ServerConnection As ServerConnection = New ServerConnection(sqlconnection)

Dim srv As Server = New Server(ServerConnection)

'Declare a BackupDeviceItem by supplying the backup device file name in the constructor, and the type of device is a file.

Dim bdi As BackupDeviceItem

bdi = New BackupDeviceItem(txtRestoreFile.Text, DeviceType.File)

''Define a Restore object variable.

Dim rs As New Restore

'Set the NoRecovery property to true, so the transactions are not recovered.

rs.NoRecovery = True

rs.ReplaceDatabase = True

'Add the device that contains the full database backup to the Restore object.

rs.Devices.Add(bdi)

'don't know why the below norecovery is changed to false

rs.NoRecovery = False

'Specify the database name.

rs.Database = sqlconnection.Database.ToString()

sqlconnection.ChangeDatabase("master")

'Restore the full database backup with no recovery.

rs.SqlRestore(srv)

Exclusive User Access To Database

Sep 29, 2007

Hi All,

My question is regarding SQL Server database security. I want to create a login using SQL Server Authentication and assign it db_owner rights for my database. So far so good. But the critical part is that I want to give exclusive rights for my database to this user only i.e. no other users (dbo, guest etc) should be allowed to access my database.

It will be good to present here the scenario which I need to implement. I am running an ASP.NET application that uses SQL server 2005 db at back end. The database server might have other databases as well but I don't want the administrator (either SQL server admin or the server administrator) to be able to get access to my database or even view the schema. I don't want any other user except my own user to be able to detach the database or perform backup or restore operations.

I hope I was able to deliver the requirement.

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!

How To: Implement Exclusive Access To A Given Record.

May 5, 2008

Purpose
I would like to know if it is possible and if so how to implement exclusive access to a given record within in a database table.

Example
For example, you can open a file system file with exclusive access so other processes cannot access the file until it is released. I would like to implement a solution that provides this same exclusive access at the database record level. Preferably a solution that does not require creating and managing table access state flags. (i.e. FieldName.State = (Closed, Opened, Exclusive)) I would like for the database server to mange this solution and return an error status when trying to access a record that has been opened exclusively. Furthermore, I would like to avoid using triggers.

Application Utilization
Im working on a system that has multiple threads that are each responsible managing data from the same normalized table. Each of these system threads work on the same unique record in parallel. Therefore it is possible that thread (0)s changes could be overwritten by thread (n)s. I would like to have each thread open the unique record exclusively and release it when finished. All of the other threads would loop until the record is released.

Questions

1. Is it possible to implement this at the server level?

2. What would be the easiest best practice for implementing this functional requirement?

Thanks,
Sean

Database Access Via COM Objects - V- Database Access Via Stored Procedures

Aug 17, 2000

We have been asked to look into using stored procedures with SQL Server 7.0 as a way to speed up a clients site. 99% of all the articles I have read along with all the books all say Stored Procedure should be used whenever possible as opposed to putting the SQL in your ASP script. However one of my colleagues has been speaking to Microsoft and they said that that they were surprised that our client wanted to use Stored Procedures as this was the old method of database access and that now he should really consider using COM objects for data access as itis much faster. Has anyone got any views on this or know of any good aticles regarding this matter ?

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?

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.

Exclusive Insert Lock On A Table

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,

Query Trouble Regarding Bitwise Exclusive

Feb 25, 2001

HI, i am trying to make query that has computations with it. but when there's a point computing between int and float i had to use cast() function to convert certain data types. somehow it only works on converting float to integer because when i'm converting an integer into float inorder to be computed with a float it bombs. my query is like this ....


SELECT cast(((cast(((lat - (SELECT LAT FROM TPS_ZIPUSA WHERE ZIP_CODE = 00210)) * 69.1) AS int) ^ 2) + (cast((69.1 * (lng - (SELECT Lng FROM TPS_ZIPUSA WHERE ZIP_CODE = 00210)) * (COS((SELECT LAT FROM TPS_ZIPUSA WHERE ZIP_CODE = 00210) / 57.3))) AS int) ^ 2)) AS float) ^ .5
FROM TPS_ZIPUSA


.5 is where the query bombs. any idea why is this happenning?

by the way, i'm using sql server 7.0.

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.

Having A Mental Block On An Exclusive Join

Feb 9, 2008

Hi, I've got three tables that I'm trying to pull data from. The first is a family of rings, the second is the individual rings and the third relates one ring to another:

RingFamilies
------------------------------------
FamilyID pk | FamName
------------------------------------

Rings
-------------------------------------------
RingID | FamilyID fk | RingName
-------------------------------------------

RingAssociations
-----------------------------------------
RingID1 pk/fk | RingID2 pk/fk
-----------------------------------------

I'm trying to pull a list of RingIDs and names for a given FamilyID. To complicate it, I want to exclude rings that are already associated to a given RingID, i.e. I only want the unassociated rings in a given family. To complicate it even a little more then name needs to be the FamName+RingName...is this possible? Thanks!

Given @FamID and @RingID
Result Table
------------------------------------------------
RingID | FamName + RingName

Mutually Exclusive Counts On Ordered Queries

Jul 23, 2005

Ive been playing with this for a few days and thought I might thow itout for seggestions.I have Several Queries that need counts returnedThe Queries are Mutually Exclusive meaning whatever Query they returnin first they cannot be included in the counts of any queries belowthem.This set of queries for exampleSelect ID From Customers where FIRST_NAME = 'Chris' (would return say150)Select ID From Customers where ST='OH' (This would retunr say 50, BUTRun alone it might return 70, however 20 of those were in the firstQuery so they arent to be retunred in this result set.The total for Bot Queries would be 200But If I reverse it like soSelect ID From Customers where ST='OH' (This now returns 70)Select ID From Customers where FIRST_NAME = 'Chris' (This now returns130)The total of course for BOT Queries is 200 but I dont need that total Ineed the total for EACH Query depending on its orderingWhat I need are the single counts depending on the order in which thequeries are runIt seems like a recursion problem, but It might go past 32 level so Icant use recursive SQL ( I dont think )I've thought of (or tried to think how to use Not In, Not Exist, etcbut still dosent come up with the results....)How Can I grab the counts for each Query ?Chris

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 ?

Data Access :: Server Rejected The Connection - Access To Selected Database Has Been Denied

Jun 10, 2015

I have recently upgraded to SQL2014 on Win2012. The Access front end program works fine.

But, previously created Excel reports with built in MS Queries now fail with the above error for users with MS 2013.  The queries still work for users still using MS 2007. 

I also cannot create any new queries and get the same error message. If I log on as myself on the domain to another PC with 2007 installed it works fine, so I don't think it is anything to do with AD groups or permissions.
