Hello All,
I want to deny all user connections to be denied to a Database cluster. How best to do it?
As per my research I can use DENY CONNECT SQL TO instead of sp_denylogin but how can I deny login to say NORTHWIND database?
Also To kill all the connections to the database will the following command work best or should I use something else?
SELECT 'KILL' + CAST(spid AS nvarchar(10)) FROM SYSPROCESSES
Thanks
Hi All,
I would like to disable a user account from logging to the database. I would like to know the difference between deny connect to sql permission and disabling an account by alter login disable. Please advice. Thanks
I have a customers table and a stored procedure for deleting records from this table. I connect to sql using a connection string with sql server authentication using a user I've set up in sql server. This user has roles public, db_datareader and db_datawriter and has permissions to execute all my custom stored procedures. Up to this point everything is fine and I can insert, update and delete. Happy days.
If I then select the permissions for the user and deny delete permission on the customers table I thought that because deny overrides everything else I could not delete a customer from my application. Much to my surprise, I can. Why is this?
Hello, I Have created a folder in the IIS called Webreporting. I used sql server to generate HTML into that folder. I make NT security to that folder so certain people can view the report. Unfortunatelly my code to generate the scheduled HTML report failed and gave this error message:
Server: Msg 16821, Level 11, State 1, Procedure sp_makewebtask, Line 125
SQL Web Assistant: Could not open the output file.
Hello,
Is is possible to Grant a 'DENY DELETE' on a table to the 'sa'user or will the fact that he is administrator over ride the restriction.
Thanks

Hello everyone,
Is there a way to deny a specific application from connecting to SQL Server? There is an application some of my developers use that connects with Windows Authentication that I would like to block from my production server. I can't deny the user's logins because they need to be able to connect to the server from other applications.
Does anyone have any suggestions?
Thanks in advance,

Hi Guys,
I am unable to deny DMV rights to public. I have already ran the SQL query successfully:
"DENY VIEW SERVER STATE TO public" and "DENY VIEW DATABASE STATE TO public"
However when I check my master DB, the public still have rights to all the dm_***** objects. Am I doing it wrong or is there any steps I missed out? Can anyone help please?
Thanks a million.
Any one can help me, below error messages for reference, thanks!

I was wondering if there is anyway to deny remote logins on SQL Server 7 (other then pulling the network cable out of the back :) ) so that nothing can login during a service pack upgrade?
Many thanks in advance

Hi,
I need to give a sysadmin role to a user and I need to prevent that user to access some tables in specific databases...
thanks in advance...
I know this seems like a strange ask, but we have a common user and pass in most of our web applications and this user requires DBO access to the database, no problem is occasioannly we need to let a developer look at an issue on a production server, so we port them through to sql through the firewall so they can see it it, and they normally login wih there domain/username and this way they are restricted to what they can see and do. However all developers know the SQL user and pass used in the web app, they also know its a DBO, so this means they can login with these user details and have access to everything.
My question is how can i lock this down so i can deny access from the SQL management console for this particular user, but still allow the user to act as a DBO for the web applications.
your help here is appreciated.
Thanks

I have a login associated with a single user on a database (not master). I want that user to be able to only see what I've specified in the securables.
Now I've created a ODBC connection using that login. The problem is that the user can also see the master db info. I was expecting to see just the one view I created and granted the user to view. How do I get rid of all the master db stuff?
Hi all,
I'm trying to write a database table that is ONLY accessiable to ONE login / DB user and restrict access to what that user can do with the table.
At the moment I have granted SELECT & INSERT permissions but some of the fields in the table should also be restricted, but for some reason SQL doesn't allow a deny on INSERT for columns.
It seems strange that you can deny an UPDATE permission on a column but not INSERT, so users can create new lines of junk into fields you dont want them to, but cant change that junk afterward??
Anyone have any ideas how I can prevent this user from altering these fields at all?
Thanks in advance
I'm having trouble creating a read-only view. I've got 1 or more tables that I wish to remain updatable but I want to create a view that covers the table and/or spans all the tables. However, I want the view to be select only. I can't seem to get it to work.
DENY UPDATE ON [dbo].[MyView] TO [dbo] CASCADE
All that seems to execute my dbo user can still use...
Update MyView set SomeID = SomeID + 10
Plus, ideally I just want to say, DENY UPDATE ON VIEW TO ALL
Any thoughts?

I€™m trying to lock down PCI sensitive data columns in some product databases
from our developers. We need developers to have data reader rights to the
production database to perform general maintenance and troubleshooting of the
application BUT minus the specific secured columns like credit card number,
etc.
I have a user role setup called RWE created by:
CREATE ROLE RWE
GRANT SELECT TO RWE
GRANT INSERT TO RWE
GRANT UPDATE TO RWE
GRANT DELETE TO RWE
GRANT EXECUTE TO RWE
A standard SQL user is placed inside this role allowing them full read,
write, and execute rights on everything in the DB which is fine.
BUT, now we want those same rights except for the sensitive data files so I
updated the rule with the following script:
DENY SELECT ON [dbo].[TableNameHere] ([strCC]) TO [RWE]
Logging in a developer and doing a SELECT * FROM TableNameHere throws a
permission error on the strCC column as expected, so far so good.
But, I did a SELECT * FROM ViewThatContainsField_strCC and shows them the
denied field. Oh, oh! I also did EXEC spStoredProcThatShows_strCC and again it
shows the denied credit card field. Again, oh, oh!
So, long story short, I€™m stuck. My understanding of SQL permissions, I was
under the understanding that placing a deny at the lowest level (column)
should throw errors in all methods of access that column (either by direct
select, or select through views, procs, etc).
Any suggestions or any hints on what I€™m missing here?
Thx ahead of time!
Can any body tell me how can I restrict a user who has Sa previlages, from droping a table. He should be able to do everything except droping the table.
Thanx in advance.

I have a database X where user A has db_datareader role. User A can select data but cannot update/insert/delete.
Recently user A connected to my database using Brio SQRW tool and could successfully run an update command in database X. As I researched I found out that SQRW uses RPC calls with extended procedures sp_prepare and sp_execute to run an update command.
User A does not have explicit permission to either of these stored procedures. Additionally User A does not have access to master database where there procedures reside.
How can I prevent user A from updating my data?
Hi All,
I have a SQL server, as I use a domain account to log on to SQL server and Sql server agent, all maintanence plans work good, since I changed from a domain into Localsystem account to log on to SQL server, and Sql server agent, all maintanence plans didn't work any more, then I tried only keep Localsystem account at SQl server , using a domain log on to Sql server agent, but it's still failed to maintanence plans. The error in job history is"Executed as user: candyl. sqlmaint.exe failed. [SQLSTATE 42000] (Error 22029). The step failed.". And the message at Sql server log is :"BackupDiskFile::CreateMedia: Backup device 'D:Database BackupsNoon BackupESMDEV_db_200406141548.BAK' failed to create. Operating system error = 5(Access is denied.)". It looks like permission problem, but for Localsystem account which should has full permission, right? I tried may ways and searched from knowledge base , still couldn't find the related solution.
Anyone can give me some advices?
Thanks.
Is there a way to deny Security Permissions to a login that has sysadmin? Unfortunately I have to leave the user as sysadmin. I trying denying alter any login and control server but that didn't work.
View 3 Replies View RelatedYou can't assign a default schema for a user that maps to a Windows group. OK fine. But if you create a user for that group anyway with no default schema, any objects created by members of that group will automatically cause a schema to be created for them, EVEN WHEN THAT USER HAS BEEN EXPLICITLY DENIED THE CREATE SCHEMA PERMISSION IN THE DATABASE. This is the same as it was in 2K5, but has still not been fixed in 2k8.
To reproduce, do the following steps:
Create a windows group, either in the doman or local to the box.
Add at least one Windows user to that group.
Create a SQL login for that Windows group.
Map that login to a new user in some database.
Explicitly 'deny create schema to ' that group/user.
Grant 'create procedure' to that group/user.
Log onto SQL with a Windows login that is a member of that Windows group
Use the database that we set the permissions in above.
Create a dummy stored procedure without qualifying the name with a schema ie: 'create prodedure test1 as select 'hello world').
Look to see what you ended up with. You will have a new schema named the same as the user who created the sproc. This will now be their default schema implicitly, and the test1 stored procedure will be in that schema, EVEN WHEN THAT USER WA EXPLICITLY DENIED THE CREATE SCHEMA PERMISSION IN THE DATABASE.
Could you please fix this?
Hi all, Is there any easy way to not allow a user to see system views? I have set up 1 view for a login, and I have to use an ODBC connection to access it. However, the 3rd party application I'm using is apparently timing out because of the number of tables/views that are returned. TIA! - Mark

This is my first post to this forum.
I would like to know if there is any way to restrict users from creating temp tables.
Problem: I am facing problems with lots of temporary objects getting created in my database. The users have read-only access to the database for adhoc-querying purpose through QA. Yet they are able to create temporary tables in tempdb database taking lot of resources on tempdb disk causing abnormally high growth of tempdb.
Thanks in advance.

Hi Guys,
We are using MS SQL 2005. I am ask to remove the PUBLIC rights to the objects listed in the following query in the master DB:
SELECT sysusers.name, sysobjects.name,sysprotects.action FROM sysobjects, sysusers, sysprotects WHERE sysobjects.id = sysprotects.id AND sysprotects.uid = sysusers.uid AND sysprotects.protecttype = 205
I keep having the "Cannot find the object [Objectname], because it does not exists or you do not have permission."
How do I create a query to remove the PUBLIC rights at a single run. (There are total of 1660 items, please dun ask me to write the DENY or REVOKE statement 1660 time )
How do I DENY the rights for objects starting with the prefix "dm_" or items like "TABLE PRIVILEGES"
Thanks guys Any help on this is greatly appreciated.
I need to remove full admin privs from the builtinadministrator's group in report manager.
I tried removing the builtinadmin role from report manager and SQL Server, I removed it from the Site Settings area and from each individual folder's permissions.
Yet all the members of that group still have full run of the report server...
I even made a new folder that ONLY I am listed as having permissions to, yet they can see that as well...???
Suggestions?
I create a new user who will have a read only permission on TestDB.
I want to give only select permission on TestDB and also I don't want that the new user will not see any other database.
DENY VIEW ANY DATABASE to user_readonly
ALTER AUTHORIZATION ON DATABASE :: TestDB TO user_readonly
but when I am using the above query then the new user is the owner of the testdb. i don't want that. I want that the user will have only select permission on the table.is there any way?
1. A few months ago, I received a request to deny delete to a group (Windows AD login) against 3 databases. So I issued a DENY DELETE to the relevant Windows login.
2. Now, someone is having trouble updating data. The issue seems to be that a trigger fires during the update. In the trigger the code tries to delete from a table in the previously delete-denied databases. So the update fails.
-- In retrospect, perhaps I should have used REVOKE - not sure
-- Also, I can't seem to find a listing of the DENY permissions - or rather, how to list what permissions are denied. I guess maybe that is a hard thing to do if the result of a DENY is to leave certain permission columns NULL (vs adding 'DENY'). But it would be useful for me to see what the current permission state is.
-- Finally, I tried to undo the DENY without success. Here is my attempt.
a. I tried GRANT DELETE... - no luck
b. Then I saw an article explaining to use REVOKE, so I tried 'REVOKE DELETE' followed by 'GRANT DELETE' - still no luck.
How can we deny an Object select Permission which have Sysadmin role.
View 2 Replies View RelatedHow do I deny insert / update / delete on a handful of tables for all DB users on a database? These users need and have DB_Datawriter permissions.
View 2 Replies View RelatedWe've had two instances now where when there is a network connection timeout to the mirror from the primary, the primary db server goes to 100% utilization and refuses all connections.
The first time we had to reboot the primary, the 2nd time mirroring picked up again 10 minutes later.
There are two dbs being mirrored, one is 15gig, the other 4gig. Both boxes are running SQL2005 64 bit and Win 2003 64bit.
This happened at 6am and typically there shouldn't be a lot of traffic at that time but here are the error messages in the SQL log below.
We are going to try and move db communications to a separate network and network card - but this looks like either a bug in mirroring or a configuration problem on our end - though it works just fine other times.
Any thoughts/suggestions would be greatly appreciated.
Thanks!

Is there a way to deny the users the ability to open a server via Management Studio but still allow remote connections.
In my program I need an admin login to do various things. I am using the sa login and setting the password on install of Sql Express. But, if someone changes the password for the sa login after installation and I have the login for sa hard coded in my program, then everything will break. Is there a way to make sure that no one can change the sa password?
Just encountered something that I wasn't expected, in that a user who has an explicit deny on a column in a table was able to select it when referenced through a view in a schema they have the SELECT permission on. This seems to me to go against the principle that DENY overrides everything when it comes to permissions? Is this how it's meant to work?
Code is below:-
--create test user
CREATE USER TestDenyOnViewUser WITHOUT LOGIN
GO
--create test schema (authorization dbo - same owner as dbo schema so ownership chaining will apply)
CREATE SCHEMA TestDenyOnView AUTHORIZATION dbo
[Code] ......
We want to deny access to sql server 2005 database by the sql management studio or any other sql editor while our developed application can access the database even malicious user gets the login name and password by disassembling our code
We have a generic sql login "prduser". Applications use this login. We want the login NOT to have ALTER PROCEDURE and DROP PROCEDURE permissions only on the stored procedures(there are thousands of them).
