How To Prevent Users From Logging To DB During Its Maintenance

Jun 11, 2004

I am really a DB admin beginner, so hopefully it'll be easy for you to answer my simple question:

How can I temporarily prevent users (except "sa") from logging to database(s) or better to DB Server while there are applied scripts on them ?

I have already tried TCP/IP port changing, hiding server, running a single user mode but the reult was very poor. Please note that "sa" has to be able to connect to DB Server from a third party application but other users not.

Any idea and/or a known solution ?
Thanx in advance for your hints

Archive Data Instead Of Deleting It To Prevent 4GB Data Limit

Mar 14, 2008

We are running SQL Server 2005 express on Windows 2003. The database server gets significant amounts of data.



Because of the 4GB data limit we have a daily cron task which goes through and deletes data older then 90 days.



We would like a way to archive this data instead of deleting it. Is there any way to take data and compress it and store it in a different way, so that if needed, customers can query directly out from the compressed data? Cleary querying from compressed would be slower but that is ok.



Any other solutions that would allow us to archive data instead of deleting it? Thanks.

Prevent Data Being Inserted Twice

Nov 14, 2006

I have a table with 3 columns: ID, Status, DateTime.

I created a stored procedure to insert a staus value for each ID. This will run every hour. The DateTime stores the time, date when the Status was inserted.

If the procedure was to be run a second time in hour window I do not want any Status to be inserted.

Note: that I cannot rely on the procedure being run at exactly the right time - if it was scheduled to run on the hour (i.e at 1:00, 2:00, 3 :00 etc) but didn't run until 1:20 it sould still be able to run at 2:00.

Does anyone know if there is anyway I can gaurd against this?

Prevent Duplicate Entries In A Table

Nov 11, 2003

I have an ASP.Net Web appplication with a Back-End SQL DB. There are 3 Tables; Users, Groups, and GroupMember.

The GroupMember table is used to link Users to Groups and consists of just two fields; userID and GroupID.

Here is a sample of some data:

User1 Group1
User1 Group2
User2 Group2
User3 Group1
User3 Group3

Users can belong to multiple Groups. However, you shouldn't be able to have the same user and group comobination more than once. for example:

User1 Group1
User2 Group2
User1 Group1

I can stop this kind of duplicate data entry by doing a lookup first (using asp.net) to see if the entry already exists but this seems cumbersome.

Is there a simpler way to prevent duplicate entries in a table using sql?

Thanks a lot,

Chris

How Can I Prevent From Inserting Duplicate Data?

Dec 31, 2006

 
I have a table storing only 2 FKs, let's say PID, MID
Is there any way that I can check distinct data before row is added to this table?
For example, current data is
PID MID------------100 2001100 2005101 3002102 1009102 7523102 2449
If my query is about to insert PID 100, MID 2001, since it's existing data, i don't want to add it. Can I use trigger to solve this issue?
 
Thanks.

How To Prevent DBA From Getting Confidential Data Stored In SQL Server?

Jun 11, 2006

Suppose I have a database storing some confidential information, such
as legal information, medical or financial records,  etc., and a
Web site with a membership system so that only authorized users can
view the information.

I understand I can encrypt the information, and the user's passwords,
so that if the database is compromised it still shouldn't be possible
for an outsider to view the confidential information.

However, what about people who have legitimate access to the database,
such as the DBA, Web developer, etc., but who should not be able to
view the confidential information?  For example, even though the
user's password was encrypted, what would stop the DBA from replacing
the user's password with his own (encrypted) password, then logging in
and viewing the user's info, then copying back the original encrypted
password?  Or, adding a new user for himself with whatever
permissions he chooses?

Does Db_denydatawriter Prevent Procs From Updating Data?

If a user is a member of a role which would allow him to execute a proc which updates a table, and he is then granted db_denydatawriter , can he still update the table through the proc? SS2000 SP4.

Thanks,

Since posting this I tested the scenario and YES! The user was still able to execute an update proc even though the user excuting the proc was granted db_denydatawriter.

How To Prevent Table-locking With Multiple Queue Readers

Apr 26, 2007



In a situation where messages are coming in faster than they can be processed, at what point will service broker start up another queue_reader? Also, how do you prevent table locking if part of the processing of that message involves inserting or updating data in a table? We are experiencing this problem because of the high number of messages coming through, and I'm not sure what the best solution is - does service broker have some built-in support for preventing contention on a table when multiple readers are running? Or maybe a pattern that can be used to get around it?

Integration Services :: UPDATE Data Overwritten - How To Prevent

Nov 16, 2015

I'm trying to find a way to maintain the data that was UPDATEd in a table from being overwritten.

I used UPDATE in a table to include missing data.  However, since I do not have access to the original table from where the data is derived, when I run my query, it knocks out the data in my table that was updated, because it is linked to the orginal table that has the blank fields. A few users do not have an employee email, and this has to be updated with a personal email account for now.  

My update works fine, but is there a way I can use the statement in my query so that it updates each time it is run to maintain the user email address? This will solve the problem of not having to change the original table that I do not have access to.

if exists (select * test..dbo.Employee)
truncate TABLE
 test.. dbo.Employee
insert into test.. dbo.Employee (EmployeeNumber  
    , EmplUsername  

[Code] ....

Analyzing Lock Order Of Queries Against Same Table To Prevent Deadlocks

Aug 5, 2014

I need to discover the actual order in which locks are acquired on a table during a query.

This with a goal of analyzing the lock order of queries against the same table to prevent deadlocks.

I'm using SQL Server 2008 R2.

From Management Studio I execute:

begin transaction
<my query>
exec sp_lock
rollback transaction

In the output I see interesting information about which locks are acquired, but:

- are this locks ordered by the time they're acquired? That is, can I be sure that lock at row n is acquired before lock at row n+1?
- if not, how can I get this information?

Setup And Upgrade :: Prevent Saving Changes That Require Table Recreation

Jun 3, 2015

I know there's an option in the SSMS to remove the hook at the option "Prevent Saving changes that require table re-creation".

But how can I set the option silent. I mean for instance at the setup or by a secret T-SQL command or setting a value in a hidden file? I don't want the user to open the options dialog.

I logged the registry by a tool and alas there was it. So the thing is to set the registry entry by our own setup after installing the SSMS.

[HKEY_CURRENT_USERSoftwareMicrosoftSQL Server Management Studio12.0DataProject]
"WarnTablesReCreated"=dword:00000001

How To Prevent System Form Locking A Table In Case Of Large Insertion

May 2, 2008

Hi,

I found out that executing the procedure SP_INDEXOPTION and setting 'AllowRowLocks' to false i can prevent the sql server from locking rows in a table and 'AllowPageLocks' prevents from pages being locked. I need to preform same operation
in case of tables. I need to perform insertion operations concurrently and acquire required locks manually. Is there a way to stop sqlserver from acquiring locks on the table. I need to disable all the locks (row, page and table).

Thank you in advance.

Data Access :: Users Get Wrong Data Records - Cross Coupling When Accessing Files From MVC App

Aug 7, 2015

I have an MVC asp.net application that stores many records in a table on sql server, in its own system.  used the system for 2 months, worked fine accessing, changing data.

Now that other users are logging in? there is cross coupling going on.  one user gets the data from another users sql search.

In the mvc app it had used the get async method to read the ID record from the db, i set that to synchronous.  no effect;  the user makes their own login id but that does nt matter either.

SQL Security :: Making Data Change In Read Only Database Without Letting Other Users Update Data

Aug 6, 2015

I want to make data changes in read_only database , that's why i must set database read_write. While database is at read_write mode, i want to be sure that no one makes change in database.

For this aim, i write the code below, but i suspect that after setting the database read_write, till the setting database
single_user ,is it possible get DML script from another user. Is the code below enough for this operation. Or is there another way?

Reminding: Read_only database can not be set single_user mode. That's why, first you must set database read_write.

The code;

use master
alter database xxx set read_write
with rollback immediate
alter database xxx set single_user
with rollback immediate

use xxx
update  tablexxx set columnxxx=yyy
use master
alter database xxx set read_only
with rollback immediate
alter database xxx set multi_user
with rollback immediate

Data Unexpectedly Changing In Data Flow Task

Oct 3, 2007

I have a fairly simple data flow task that loads data from one table (OLE DB Source) into another table (OLE DB Destination). The data type for one of the pairs of columns is nVarChar(120) and it contains version information that looks like a decimal. When I run the export, the destination has a trailing zero added after the decimal point as if it were a numeric column which invalidates our comparisons (string 1.0 is not the same as string 1.00). There is no cast or convert done to this column, it is a straight copy. Any ideas what could be causing this or how to fix?
