How To Protect Data Of One Table?
Dec 13, 2006
I have a DB on my SQL Server Express 2005. In this db I have one table and I DON'T want any user can modify data on this table but I want only show this data (only select statements allowed). If I install this db on one of my customers' machine, I can see that he can modify data into this table If he log in into the database with windows authentication and not with the "USERLOGIN" that I have created with sql server authentication. What can I to to remove dbo access in Windows authentication in my db and "transfer" the dbo in another user access (like MYUSER with Sql Server authentication)?
Thank You

My client maintains its HR data in an application that uses Oracle as its backend. This highly-sensitive data is basically off limits to all but a select few. Presently, I use a program in Access 97 that allows one high level HR person to pass their login to linked Oracle tables and copy a large chunk of this data to Access tables. From there I can morph it as needed for the Personnel, Safety, EEOC and other areas. The client sees this PW-protected, encrypted Access DB as safe because, being "only an Access DB", it falls below the radar of IS. This basically means IS can't get to the data. However, accessibility and scalability are non-existent. I'd like to reduce the Access DB to a shell that simply links to Oracle and SQL Server 7 tables and performs a straight pipe of the raw data between DBs. However, now IS will be very interested (since it's SQL 7) and have Admininstrator rights, therefore causing the HR people to squash the deal. How can I lock SQL 7 up so tight that IS can't get to the data and yet be able to maintain the DB? If this is not feasible, are there any other options that might provide a solution?

I got a problem concerning encryption. The thing is I have decided to use symmetric key protected by certificate to encrypt certain information. Certificates are protected by database masterkey and by service key.
But I also want to be sure that if someone steals my database with all its data he wont be able to decrypt it with his own SQL Server Management Studio where he has all the permissions.
Also after some time I will need to take my database and set it up on another PC.
Has anyone ideas how to solve this??
P.S. As far as I know if symmetric key is protected by certificate which is protected by DB master key and service master key then you cant decrypt data if database is moved to another workstation and opened with another Management Studio. Please can anyone explain how this works( if its true). And if this is true then how can i move my DB without loosing access to encrypted data???

We have a commercial VB.NET winforms client/server application that utilizes SQL Server 2005 express edition. The schema and data that the application utilizes is proprietary and could be very damaging if it got into a competitors hands.
Is there any way to protect the data and schema of a sql server 2005 express edition database?
Will this functionality ever be added?
Thanks

Hello.
I have a report with parameter called "parm1", that gets a value of "true" or "false" depanding on another parameter.
When the report is runnig the parm1 value is "false".
How can I protect this parameter from a change by the user?
I mean - the user can run the report and then add to the url "¶m1 = true".
Can I do anything against that?
I tried marking it as "internal" and I thought that now it can get his value only from inside the report but it didn't worked.
Any ideas?
Thanks.

Hi,
Just read about SQL injection, and tested it out with sample database, and it does hack my database, the article show to prevent SQL injection by using application code to remove those keywords and change single quote to double quote, is there any method to prevent SQL injection directly using the database system itself, maybe stored procedure or anything?
Thanks.

Dear Colleagues,
I have designed a Microsoft SQL Server 2005 database application using Visual Basic 2005. I want to control access to the database programmatically, without the End-User opening the database in SQL Server.
I want to protect the database structure such as my tables, code, etc. This restriction should include all the Administrators of the Computers on which my application will be deployed. Any modification of my database or code should be implemented only by me.
What is the best way to do this using (a) Windows Authentication Login? (b) SQL Server Login? How do I configure the User-Login?
NEW: In addition to above question, how best do I achieve this protection if installing the DB with other databases in an already existing server, is it possible to remove the Builtin Admin from the server role?? As in my case, there is no need for anyone else to open the DB in Management Studio at all as my VB application does all that is required.
Thanks and best regards,
Peter

I want only SQL Server Authentication not Windows Authentication Because If some one copy database and attach at some other place using Windows Authentication then they can see each and everything.
I want something like Access (I know its password can be broken very easily)
I want to protect Table & SP Schema, Data is not much important.
Its urgent

Hi Everybody:
We have a table which needs to be updated 2 million times per day. It hosts all real time transaction. There are 200K records in this table. Would you please to share your experience with me about how to protect/save such table in SQL 2000 from any possible damage?
We plan to use point-in-time backup (every 5 minutes). It still takes at half an hour to recover the whole database. Any new technology from Microsoft or SQL 2000 you can recommend?
Thank you very much.

Hey!
This post contains the code for this thread: http://www.sqlteam.com/Forums/topic.asp?TOPIC_ID=14475
It deals with the problem how to prevent log actions in long running batch jobs from being rolled back. It was heavily inspired by Andy Pope´s approach to error handling (http://www.sqlteam.com/item.asp?ItemID=2290) and in fact you will see much of his code here.
The code:
This procedure dynamically opens a second connection in parallel to the existing connection of the calling procedure using SQL-DMO. So the second connection runs without the scope of transaction of the calling procedure. So no action you take here is rolled back in case the calling proc fails. So be careful! Keeping data integrity is your job here and you could do many weird things to your database.
The procedure dynamically adds a user function that if called just would return the object token of the new DMO connection. So any piece of code in the same batch could reuse the exisiting connection.
LogConstructor
CREATE PROCEDURE LogConstructor AS
if exists (select * from sysobjects where id = object_id (N'dbo.MFF_GetLogObject')
and OBJECTPROPERTY(id, N'IsScalarFunction') = 1)
drop function dbo.MFF_GetLogObject
DECLARE @Error INT
DECLARE @ErrorMsg VARCHAR(255)
DECLARE @oSQLServer INTEGER
DECLARE @Source VARCHAR(255)
DECLARE @Return INTEGER
declare @dynsql nvarchar(3000)
-- Create the SQLServer object
EXEC @Error = sp_OACreate 'SQLDMO.SQLServer', @oSQLServer OUT
IF @Error <> 0
GOTO OA_Error
-- Set the login process to use NT Authentication
EXEC @Error = sp_OASetProperty @oSQLServer, 'LoginSecure', -1
IF @Error <> 0
GOTO OA_Error
-- Connect to server using NT Authentication
EXEC @Error = sp_OAMethod @oSQLServer, 'Connect', NULL, @@SERVERNAME
IF @Error <> 0
GOTO OA_Error
-- Verify the connection
EXEC @Error = sp_OAMethod @oSQLServer, 'VerifyConnection', @Return OUTPUT
IF @Error <> 0
GOTO OA_Error
IF @Return = 0
GOTO OA_Error
-- Create Function with server object
select @dynsql = N'CREATE Function MFF_GetLogObject () RETURNS INT AS BEGIN RETURN ' + cast(@oSQLServer as varchar) + N' END'
EXEC sp_executesql @dynsql
return
OA_Error:
-- Get the error text
EXEC sp_OAGetErrorInfo @oSQLServer, @Source OUT, @ErrorMsg OUT
SELECT
@ErrorMsg = CONVERT(CHAR(16), @Error) + ': ' + @ErrorMsg + ' (Source: ' + @Source + ')'
print @ErrorMsg
return
GO
The next procedure just drops the DMO connection and also drops the user function as the token is invalid by now. This proc should be called within the same batch as the constructor to clean things up properly.
LogDestructor
CREATE PROCEDURE MFP_LogDestructor AS
declare @lo int
select @lo = dbo.MFF_GetLogObject()
exec sp_OADestroy @lo
if exists (select * from sysobjects where id = object_id(N'dbo.MFF_GetLogObject')
and OBJECTPROPERTY(id, N'IsScalarFunction') = 1)
drop function dbo.MFF_GetLogObject
GO

I am exporting the data from database to an excel template that will have 100+ columns and approx 4000 rows of data. Then the business user will make changes to some columns without modifying primary key columns and will send back to us where we will update the same to database.
In order to this am using an excel template by protecting the primary key columns with a password protection.
At template level am fine and whenever am trying to modify any primary key column it's not allowing and am totally good there. But when I use that excel template as a destination to load data from SSIS, all the protected columns are no longer protected and i could able to make changes.

I have a problem protecting a SQL 2005 SP2 server on Windows Server 2008 (64bit), running DPM 2007 on Windows Server 2003 (32 bit).
The following SQLVDI event ID 1 is logged in the event viewer:
SQLVDI: Loc=SVDS:pen. Desc=BADMEM. ErrorCode=(-1). Process=2972. Thread=6504. Server. Instance=MSSQLSERVER. VD=Global{CC60D260-C5DD-406A-9E63-64A9503A9763}1_SQLVDIMemoryName_0.
The UUID changes each time the event is logged, but the first event is followed by:
SQLVDI: Loc=SVDS::Cleanup. Desc=Close(channel). ErrorCode=(6)The handle is invalid.
. Process=2972. Thread=6504. Server. Instance=MSSQLSERVER. VD=Global{CC60D260-C5DD-406A-9E63-64A9503A9763}1_SQLVDIMemoryName_0.
Then this is repeated twice:
SQLVDI: Loc=SVDS::Cleanup. Desc=Close(channel). ErrorCode=(6)The handle is invalid.
. Process=2972. Thread=6504. Server. Instance=MSSQLSERVER. VD=.
Event ID 3201 is then logged by MSSQLSERVER:
Cannot open backup device '{CC60D260-C5DD-406A-9E63-64A9503A9763}1'. Operating system error 0x80770006(error not found).
This is followed by Event ID 3041:
BACKUP failed to complete the command BACKUP DATABASE CommunityServer. Check the backup application log for detailed messages.
It looks to me like the virtual device creation fails in the first step, the next three event messages are the cleanup of the failed virtual device, and the final two messages are the failed SQL backup as the expected device doesn't exist.
My question is why? The message seems to indicate bad memory, but I'm sure the physical memory is good - The 16GB in this server has been tested extensively, and I have no other issues. Perhaps its some sort of memory allocation error?
I'm going to apply cumulative update 7 to this SQL server to see if it makes a change. What's the latestest version of sqlvdi.dll available?
TIA,
Karl.

I am attempting to create a stored procedure that will launch at report runtime to summarize data in a table into a table that will reflect period data using an array type field. I know how to execute one line but I am not sure how to run the script so that it not only summarizes the data below but also creates and drops the table.
Any help would be greatly appreciated.

Hello all,
Please help....
I have a text file which needs to be created into a table (let's call it DataFile table). For now I'm just doing the manual DTS to import the txt into SQL server to create the table, which works. But here's my problem....
I need to extract data from DataFile table, here's my query:
select * from dbo.DataFile
where DF_SC_Case_Nbr not like '0000%';
Then I need to create a new table for the extracted data, let's call it ExtractedDataFile. But I don't know how to create a new table and insert the data I selected above into the new one.
Also, can the extraction and the creation of new table be done in just one stored procedure? or is there any other way of doing all this (including the importation of the text file)?
Any help would be highly appreciated.
Thanks in advance.

Hi AllWonder if you could help, I have a bog standard table called STOCKPRICESthat has served me well for a while, but now I need to change the structureof it and because a number of users have used it in it's present form I needto so the following in SQL script:a) Grab a snapshot of the current SQL data.b) Re-structure the STOCKPRICES table.c) Post this grabbed data back, but in the new format.My script plan was to firstly to rename the current STOCKPRICES table toSTOCKPRICESOLD (you can do this can't you), create a new STOCKPRICES tablein the new format and then somehow extract the data from STOCKPRICESOLD andsquirt it into STOCKPRICES.The current schema for STOCKPRICES is as follows:# --------------------------------------------------# Table structure for table 'STOCKPRICES'# --------------------------------------------------DROP TABLE IF EXISTS `STOCKPRICES`;CREATE TABLE `STOCKPRICES` (`STOCKID` VARCHAR(30),`CURRENCYID` VARCHAR(30),`HDNETAMOUNT` DECIMAL(10,3) DEFAULT 0,`HDTAXAMOUNT` DECIMAL(10,3) DEFAULT 0,`RRPNETAMOUNT` DECIMAL(10,3) DEFAULT 0,`RRPTAXAMOUNT` DECIMAL(10,3) DEFAULT 0,`NETAMOUNT` DECIMAL(10,3) DEFAULT 0,`TAXAMOUNT` DECIMAL(10,3) DEFAULT 0,INDEX `indxCUURENCYID` (`CURRENCYID`),INDEX `indxSTOCKID` (`STOCKID`));Like I said it's very basic.My new table wants to be like the following:# --------------------------------------------------# Table structure for NEW table 'STOCKPRICES'# --------------------------------------------------DROP TABLE IF EXISTS `STOCKPRICES`;CREATE TABLE `STOCKPRICES` (`STOCKID` VARCHAR(30),`CURRENCYID` VARCHAR(30),`PRICELEVELID` VARCHAR(30),`NETAMOUNT` DECIMAL(10,3) DEFAULT 0,`TAXAMOUNT` DECIMAL(10,3) DEFAULT 0,INDEX `indxPRICELEVELID` (`PRICELEVELID`),INDEX `indxCUURENCYID` (`CURRENCYID`),INDEX `indxSTOCKID` (`STOCKID`));The new re-structure means that PRICELEVELID will include a unique referenceto the HD, RRP, standard prices (plus 3 others that I'm going to create).I know this probably very simple data architecture to you guys, but I'm sureyou can appreciate why I need to change the structure to this method so thatI'm not creating redundant data fields if the user only enters a standardprice I won't be storing nothing for the 2 x HD and 2 x RRP price fields.I don't think I've got a problem renaming the old one and re-creating thenew one, but how do I get the data from one to another?My problem is that I have:code, currency, hdnet, hdtax, rrpnet, rrptax, net, taxIVP GBP 2.00 0.35 200.00 35.00 100.00 17.50etc...and I need to get it into the format:code, currency, pricelevelid, net, taxIVP GBP hd 2.00 0.35IVP GBP rrp 200.00 35.00IVP GBP standard 100.00 17.50etc...Any ideas?RgdsLaphan

I have a column defined as smalldatetime. Default length (4), and "allow NULLS" is checked.In the Enterprise Manager UI, when i enter data into that table row, if i just tab past that column, all is well, and the value is represented in the UI as <NULL>.The problem comes once i ever enter a date into that column. Say i have entered a date (all is well), and now i want to remove that entry and go back to NULL (after the date value has been committed, different entry session, say).How is that done?It seems to me, once a date has ever been entered into that column, now, if i try to remove it, i get the error "The value you entered is not consistant with the data type or length of the column, or over grid buffer limit". I have tried deleting the value, entering spaces, entering the string NULL or the string <NULL>; maybe some other tries as well, but none works, i always get that error message and am not allowed to proceed past that cell until i restore a date value to it. I want to get back to <NULL>.Anybody know?Thank you.Tom
