wierd thing - i am trying to write a program that use simple access database but 5 user can access it at the same time ,
i wont to know if the database is in use by other user before attemping to write to it ,
but i notice that DBNAME.ldb file even when exsist i can some times write to the database - so to chack if this file is exsist will not be the sulotion , some one know how to chack it?
What is they best way to get data from a locked Access database into SQL Server? Linked Server, DTS Package, or should I just directly access it from my App?
Thanks.
Am I imagining it or did I read somewhere once about an tool/command/method that allows the administrator/dba to access the server even if no-one else can - probably only in certain scenarios.
I think it had a use for a situation where all the connections are used up and no further connection pooling can kick in for a while. This tool enabled the dba to still get to the server and I presume still be able to run stuff like sp_who and kill.
Does this ring a bell with anyone?
Hello, I am trying to configure a Script Component as a data source. Although this should be a simple exercise, I am running into a problem.
My control flow contains a Foreach Loop with a file iterator. The Directory Expression of the Foreach Loop Editor is supplied by an expression mapped to a package level variable called inputdirectory. The FileNameRetrieval Expression is mapped to a package scoped variable called filename.
My data flow is encapsulated by the Foreach Loop, and contains a Script Component as Source for the Data Flow Source, and a Flat File for the Data Flow Destination. The contents of the Script Designer are as follows:
Code Block
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper
Imports System.IO
Public Class ScriptMain
Inherits UserComponent
Dim thisFileDate As Date
Dim thisFileName As String
Dim thisFilePath As String
Public Overrides Sub CreateNewOutputRows()
thisFileName = ReadOnlyVariables("filename").Value.ToString()
thisFilePath = ReadOnlyVariables("inputdirectory").Value.ToString()
thisFileDate = File.GetCreationTime(thisFilePath & "" & thisFileName)
FileSpecBuffer.AddRow()
FileSpecBuffer.FileName = thisFileName
FileSpecBuffer.FullPath = thisFilePath & "" & thisFileName
FileSpecBuffer.CreateDate = thisFileDate
End Sub
End Class
When I debug the package, I get the following error:
The collection of variables locked for read access is not available at this point.
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponent.get_ReadOnlyVariables()
at ScriptComponent_67311120e6eb4162a3ea1f70847f04de.ScriptMain.CreateNewOutputRows()
at ScriptComponent_67311120e6eb4162a3ea1f70847f04de.UserComponent.PrimeOutput(Int32 Outputs, Int32[] OutputIDs, PipelineBuffer[] Buffers)
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PrimeOutput(Int32 outputs, Int32[] outputIDs, PipelineBuffer[] buffers)
My googlefu fails me at reconciling this. I have read various posts about changing the line ReadOnlyVariables("filename").Value to ReadWriteVariables("filename").Value, and handling the buffer assignment in PostExecute. The problem is that all examples shown are either for Script Component as Destination or Script Component as Transformation. I have tried playing with the Custom Properties in the Script Commponent set the ReadOnlyVariables and ReadWriteVariables, using a PreExecute method, a PostExecute method, all with different errors returning. I'm at a loss here. Could anybody provide me with a simple working example so that I can correctly populate my output buffer in the context of Script Component as Source?
I fully understand that I could just run a Script Task Using System.IO.Directory, and System.IO.File, but I really want to make this package work in the manner I've described. Any help would be appreciated.
Thanks,
John T
Hi all
I have heared that there is way to use SQL SMO (SQL Management Objects), or other third party tools running on a management server to send out an email or some kind of notifications if a database is locked.
Anyone knows how to do that in SQL Managment 2005.
Thanks

When I develop I sometimes forget and try to open the database file with the MS SQL Express Manager even though the web application I am devloping is still using it ... error lock occurrs and thats fine .... but what is the best way to unlock the files again? .... often I find myself having to restart the workstation because of this and thats sounds a bit like overdoing it .... there should be an easier way to unlock locked db files ...without having to restart the workstations.... is there ?

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 ?
View 1 Replies View RelatedI 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.Â
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.

I need to determine the following about the current authenticated Windows domain user who is trying to access a SQL Server via a trusted connection.
1 Has the current user been granted login access to the trusted SQL Server?
2 Has the current user been granted access to a specific database?
3 Is the current user a member of a specific database role such as (DB_ROLE_ADMINISTRATORS)?
Thanks,

I developed a database with Access 2003 and everything was working good until my tech came in and reformated my hard drive and install a new Ghost image that met our company standards.
Now I cannot go in and make any changes to any of the tables, queries and forms. All of this started when a new Ghost image was installed on my pc.
The message I get when I try to open my database is "You do not have permission to run "tblSwitchboard." I get the same error message when I try to do anything at all on the database.
I am at a loss as to what to do. Please help.
I am using the desktop sqlexpress 2005 and I was experimenting with the account setting and I accidentally disabled my access. I am using windows authentication and there is no password, just the windows login name.
How can I reactivate the login for this connection. Any help is greatly appreciated.
I am writing in regard to this post: http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=52798
Which I found while searching for a best-practice way to implement record locking in my application.
In the above referenced post the user asks “How can I tell if a row is locked?�, and the reason for asking is that the user wants to implement logic similar to this:
Select a row for editing.
If the row has been locked by a different user, display the information as read only.
Otherwise, lock the row and allow the user to edit (allow others to read).
My questions are exactly the same as the original poster of the above thread. I was surprised to see that the general response to the post was the user was taking a wrong approach and that sql server is unable to work as the user requested. I think the approach is both correct and desirable (I used it extensively as a foxpro programmer) and I would like further confirmation that sql server does not support it.
One of the things I don’t understand is the interaction between transactions and locks. Is it not possible to lock a row without initiating a transaction? Bottom line, my goal is this:
Select a row for editing.
If the row has been locked by a different user, display the information as read only.
Otherwise, lock the row and allow the user to edit (allow others to read).
However I get there is fine with me.
Hi to all,
I need help about access to mdf file. I don't know when, but sometime my application, build with vbnet, return an error on mdf database access, that is access denied, also winxp return on the mdf file the message "process cannot access the file because it is being used by another process" if I try to delete the mdf file. I can delete the file only if I stop the procss sqlservr.exe from taskmanager. I don't use instruction to open and close database, I use dataset, datatable and sql build in datatable.
Someone can say me why sqlservr.exe don't unlock the mdf file when I close my application?

When I am deleting records from a table, I am not able to select or insert records from the table. This particular table needs to be used by more users and very frequently used.
Could anyone please help with ideas.
Thanks in advance

I am having an interesting problem that has got me completely baffled. I restored a database from the .bak file of another database on my server to use as a test DB for an App. upgrade before upgrading the live side. The problem I have run into is that the application will not allow login into the DB unless the Trusted Connection user has dbo privs. The DB is not set for dbo use only acoording to sp_dboption. It is not this way on the live side and tech support for the app. and I both think it has to strictly do with something in the SQL permissions. Any Ideas on what could have happened? Is the restored DB hanging onto something from the original DB that could be causing this? The connection works great on the live side on the older version, and I have seen it work in the newer version as well. Any takers?--Dallas

View 4 Replies View RelatedI just brought SQL Server 2005 up on Windows Server 2003 a few days ago. Everything was going great up until a few minutes ago. I tried to connect using the Management Console and get the message
Login failed for user 'sa' because the account is currently locked out. Your administrator can unlock it.
It's the administrator that's locked out!
Do I have to reinstall SQL Server all over again?
My 'sa' account is locked out and the BUILTINAdministrators account does not have the sysadmin role. I removed the sysadmin role from BUILTINAdministrators for security reasons and before I could create a new account with the sysadmin role I fat fingered the sa password and locked it out. How can I get myself out of this mess.
Any help would be welcomed.

HelloI have a stand alone Java application that uses SQL Server 2000 on thesame machine. Sometimes, when we run the applications and follow acertain steps, the SQL server locks some of the table. At that point oftime, if we try to query Select * on those table, in Query Analyzer, itjust keep spinning and doesn't return anything. That tells me that thetables are locked. If I close the application then it frees up theconnection and those tables are accessible again.My question is how do I find out how and what query/update causes thetables to be locked. Is there a tool (some kind of a profiler) that cantell me what was the last insert/update/delete quesry was run before itgot locked?Please help me.

I have been using SQL2000 for a number of years and the company I work for needs a new system so I decided to install SQL2005.
I installed SQL2005 without any problems and set a complex password for SA. I tried to log on and had to make several atempts as I remmebered the password after the SA account got locked out with the following message:
Login failed for user 'sa' because the account is currently locked out. The system administrator can unlock it. (Microsoft SQL Server, Error: 18486).
The problem I have is I cannot log onto SQL at all as it is not logging on with windows authentication either!
How do I unlock the SA account or do I have to reinstall SQL?

We had a package fail when trying to get 3 buffers. I also saw another message saying "18430 buffers were considered and 18430 were locked. "
1. Why are buffers locked in SSIS
2. How can i reduce the number of locked buffers.
This one in question was a very large lookup.

Please, HELP ME !!!! :(
Hi all
First post - please be gentle :)
I have had a search of the forum and couldn't find a solution to this one.
On a clean install of SQL Server 2000 on a W2003 server we setup our database as normal, selected appropriate priveldges for everyone and all was well.
Until an adminsitraor accidently turned builtinadministors account to DENY access. We are now locked out of EM and I can't think of a way back in.
We can't access the database via the sa account as it is set to Windows Autentication, and we can't re-register the database for the same reason.
No other user has sufficent priveldges to update the master db or change authenticaion, or even log into EM for that matter.
I think we are snookered, but any thoughts are welcomed.
Cheers

New to sql server .
Have setup several pilot installations using merge replication between sql server mobile and sql server 2005. All has been perfect for over a week in all locations. last night one of the ocations stopped updating. Upon further investigation all devices kept throwing errors: "The database is currently synchronizing with the server". So I left for a further 2 hours with no change. The replication process usually takes abot 1 second and never take more than 3 or 4 seconds. There was no change to the data at all in this case either. I fixed the issue by restarting the whole server.
It would seem that there was some kind of lock on the database. Being new to sql server my question is:
Is there a way to properly diagnose the cause (I looked in the system event log and found nothing).
Is there a way to get notified if this occures again.
We are plannng hundreds of similar installations and cannot constantly monitor all of them in the hope of finding this issue again.
Regards
Nick
I am facing a problem in SQL SERVER 2005, 3 stored procedures seem to have a padlock on them and when i right click and the modify option is disabled.
I have tried logging in as SA and it seems to be the same problem, it is a database which someone else developed, but I need to modify it.
Any help would be appreciated.

Hi Folks,
When I create a Database and try to copy the MDF file, I get a message to say that the Database is locked or in use by another user.
Seems like maybe I am not doing a 'Save' operation - although I can't find one ?
If I shut down the PC and restart it, then the MDF File is freed up, although when I try to open it, there is something wrong with it.
I'd appreciate any suggestions.
Thanks a lot.
Barry
