User Trial Information
May 30, 2008Hi,
As there were 1 lakh + records were available in a table of sql server 2005 database.
There are only 4 users who can access the production server / database.
Between such time we came to know that data in that table deleted. As only one record exists out of 1lakh + records.
Now, I would like to know/find how the data was deleted or who fired the delete query and keeping only one record inside it.
Is there any log maintained whenever a user fires statements/queries in query analyser of sql server 2005.
Pls help as this was happened first time but it can be continued.

Does DB-Restore On A Different Machine Omit User/login Information ?
Jul 23, 2005Dear group,I am a DB-Administrator for a Company that creates and maintains asoftware solution based on SQL-Server and Crystal-Reports.The Crystal-Reports part uses the following method to present data.First a specific user (database authentification) is created with afixed password. Then Crystal Reports uses thisuser/password-information to login to the database and present or printthe data.I recently received a database from a customer of ours and i restoredit on my machine. It worked perfectly except that the Crystal Reportspart did not function at all (showing only blank reports).After dropping the specific user and creating the fixed password thething worked.So my question: does restoring a SQL-Server database on a differentmachine alter or eliminate login and user information ?Any reply will be highly appreciated.Greetings from ViennaUli

Jul 10, 2006== I asked this question directly to Remus and wanted to share the response to all of those people using this forum ==
We recently moved our database server from SQL Server 2000 to SQL Server 2005. All applications on our intranet development server stay the same [VS.NET 2003], but recently resources in our Dev DB server ran out of space. While doing a thorough investigation, I noticed ERRORLOG file was occupying about 35 Gig of HDD space. I immediately checked SQL Server error log and noticed an entry which says €“

The activated proc [dbo].[SqlQueryNotificationStoredProcedure-5eaf8465-d0cb-4be7-93b6-44bb979dd41c] running on queue BW_Content.dbo.SqlQueryNotificationService-5eaf8465-d0cb-4be7-93b6-44bb979dd41c output the following: 'Could not obtain information about Windows NT group/user 'BWCINCHoffK', error code 0x534.'
===========================================================================================
What is this SqlQueryNotificationService in my database? Is it a SQL Server 2005 thing? Why the same kind of stored procedure does not exist in other databases, but BW_Content? This error is getting repeated most probably every second and is filling up our server.
I believe our corporate IT people removed our domain accounts from BWCINC domain to BWCORP domain and probably some application which is using BWCINCHoffK credential is getting errored out. I tried to locate this application and was not successful.
Is there anyway that I can stop this ERRORLOG from growing? How can I delete these log entries so that I can make space on our Hard Drive? Is there an easy way in SQL Server 2005 to locate which application is creating this error?
Response from Remus:
The 'SqlQueryNotificationService-...' is the service created by SqlDependency when you call SqlDependency.Start (). The problem you describe appears because the 'dbo' user of the database is mapped to the login that originally created this database. The SqlDependency created queue has an EXECUTE AS OWNER clause, owner is 'dbo' and therefore this is equivalent to an EXECUTE AS USER = 'dbo'. The error you see is reported by the domain controller when asked to give information about the original account 'dbo' mapps to (that is, BWCINCHoffK'): Error code: (Win32) 0x534 (1332) - No mapping between account names and security IDs was done.
To solve the issue, change 'dbo' to match a correct login, using either sp_changedbowner or ALTER AUTHORIZATION ON DATABASE::[dbname] TO [somavalidlogin]
To find the databases that have this problem, run this query:
select name, suser_sname(owner_sid) from sys.databases
The databses that have the problem will show NULL on the second column.
A similar problem is described here: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=65711&SiteID=1
To remove the entries, use sp_cycle_errorlog to force a new errorlog file, then delete the huge log file.
---------------------------------------
I executed ALTER AUTHORIZATION ON DATABASE::[BW_Content] TO [sa];
I got this error in SQL Error Log once and the growth of ERRORLOG was stopped.

Error: Cannot Start Your Application. The Workgroup Information File Is Missing Or Opened Exclusively By Another User.
May 7, 2008Hi all,
I'm kinda new at programming, and am currently attempting to create a web application. I have an error when I try to insert information into a sql server database, and can't find how to fix it no matter how hard I try.
The error I get is: Cannot start your application. The workgroup information file is missing or opened exclusively by another user.
I have it so a user is logged in and is shown a form to fill out, then submits it (which creates an insert statement and sends it to the database).
My connection string is as follows:
CnnString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "data source=serverdestination;" + "User id=user;" + "Password=pass;";
If you need any more information, just let me know.
Any help would be greatly appreciated!

Concurrent Connections
Nov 30, 2007Morning
I have been searching hi and low on the web to try and find out typically which version of sql server should be used based on the number of concurrent users you will be having.
I believe that Sql Server 2005 Express should only really be used for up to 10 concurrent users while I seem to remember that Standard edition supports up to approx. 33,000 connections.
Does anybody have this information to hand as I need to write a business case to justify the potential upgrade.
Many thanks

Mar 8, 2004Hi all
I have a stored proc that runs every 4 hours - as a job. The stored proc takes about 3-5 minutes to comple, depending on number of records.
To do testing we run that stored proc manually, also.
Sometimes 2 or more people may run the same stored proc without knowing that the other person is running. This may create duplicates entries once processed.
What I want to know is, Is there a way to check if that stored procedure is currently running. If so it wont run second time concurrently.
(May be semapohres,mutex or something like that?)
(I am trying not to use a table to store whether the stored proc is running or not)
Thanks in advance.

View 1 Replies View RelatedTechnique For Concurrent Access?
Jul 20, 2005I've been asked to turn our single-user database system into a multi-usersystem. At present, each user has a copy of the MSDE on their desktopmachine and uses our program to access it. In future, we would like tocentralise our MSDE instance and allow multiple users to access it. Inorder to facilitate this, we are going to only allow one user write accessto the system at a time (I know, its a kludge, but the system was neverdesigned for multiple users in the first place).I have a single, simple question this being the case: can I update a single"read-only" bit field in a table of the database in order to flag to otherusers that the system is in read-only mode in a way that avoids concurrencyissues? ie. does an "UPDATE" query lock and unlock? ( I suspect the answeris yes! ). If anyone else has experience of these things, I would alsoappreciate some tips on how best to proceed.ThanksRobin

Puzzled By Concurrent Update
May 6, 2006I have a puzzle in my mind here. I will thank anyone who can solve my puzzle.
I am not familiar with SQL and its theories behind, so please bear with me if I am asking a stupid newbie question.
My puzzle is generally a problem of generating sequence numbers. The following SQL is only a stripped down version - it fetches the max number, add 1 to it and updates the table with the new number.
DECLARE @max int
SELECT @max = MAX(next_number) + 1 from sequence_numbers
UPDATE sequence_numbers SET next_number = @max WHERE next_number = @max
Now if user1 gets 100 and user2 also gets 100 and they both try to update the table, what would happen? I fear that the result would be 101.
One of my coworker thinks that adding 'WHERE next_number = @max' can solve the conflict - user2 will fail. His reasoning is like this:
After user1 updates the table, next_number would be 101 and user2's update will fail because his WHERE criteria is still 100.
But I think user2 still sees the old data (100) and still succeeds and thus both users update the table with number 101.
Thanks.

Group By Concurrent Years
Nov 8, 2007
Hi and thank you in advance to whomever takes the time to read this entry. I will be as detailed as possible, so I apologize for the length. The information here relates to the automotive industry, but I don't believe that is a very important detail
The overall purpose of this query is to create a compressed set of the data that exists in the database. The de-normalized information is structured like the following (including made-up data):
Code Block
PartNumber Make Model Year
-------------------------------------------------------
835100 ACURA INTEGRA 2004
835100 ACURA INTEGRA 2003
835100 ACURA INTEGRA 2001
835100 ACURA INTEGRA 2000
835100 FORD FOCUS 2002
There is any number of part numbers, makes, etc in this mix. The query that I currently use is utilizing MAX and MIN functions to determine year range, but as in the sample above, this does not take into account the fact that there could be a year skipped in the middle. I could probably use a cursor to do this, but would really like to stick to set logic if at all possible.
My existing query is:
Code Block
SELECT DISTINCT
cwi.PartNumber
,RTRIM(lv.Make) AS Make
,MIN(lv.Year) AS StartYear
,MAX(lv.Year) AS EndYear
FROM
CWIParts AS cwi
INNER JOIN PartTypes AS pt
ON cwi.PartTypeID = pt.PartTypeID
INNER JOIN PartDetail AS pd
ON cwi.PartNumber = pd.PartNumber
INNER JOIN Status AS s
ON pd.StatusCode = s.StatusCode
INNER JOIN LegacyVehicle AS lv
ON cwi.LegacyVehicleID = lv.LegacyVehicleID
WHERE
cwi.PartTypeID = 10
AND s.Status = 'Active'
GROUP BY
lv.Make
ORDER BY
cwi.PartNumber ASC
,cwi.Make ASC
In hopes to end up with a result set that has 1 row for each unique part-number, make, and consecutive year range relevant to the part-number and make. I will also need to add the functionality to add other attributes (such as Model and Liters), but those are equality based and can be passed in easily.
I had done most of this programatically in vb.net, but I would much rather push this logic back to SQL Server. Thank you all for any help that you can provide on this topic.

Concurrent Connections Limit

Hi,
I read that there's a "tecnical" limit of 32767 concurrent connections for SQL 2005 Express, and that SQL 2005 Express uses only 1GB of memory. So, what's the number of practical concurrent connections SQL 2005 Express can handle? Is it 200 ,300, 0r 400...? How much memory is consumed by every connection?
Thanks in Advance.

Database Concurrent Access Issue
May 22, 2007Dear All,
I have this .NET application that inserts lucky draw entries into SQL server. Each entry may have a range of values that the winning number will be drawn from. For example,
Entry 1: [1, 2]
Entry 2: [3, 8]
Entry 3: [9, 10]
Entry 4: [11, 11]
Entry 5: [12, 20]
The winning number will be picked from [1, 20]. Given this scenario, what is the best design that can handle the concurrency issue? If two entries are input at the same time, how to make sure it won't have the same starting value? Anyway to lock a table when one is accessing, disallowing other to run select query?
Thanks.
