Hi, I need to write some T-SQL scripts to perform a database audit of several SQL Server 2000 databases that tracks all superuser logins and access to tables. I can do this in Oracle but I am lost with MS SQL Server. Can anyone point me in the right direction? Thanks!
View 6 Replieshas anybody investigated the cost of turning on AUDITING for the SQL servers? I am talking about enabling the entire C2 Security Audit mode. How much impact the auditing has on the database performance?
Is auditing for SQL 2005 any better, meaning less impact on performance?
Any sample, test, and/or numbers to support the arguments?
Please share any findings that you have or know. Thanks
On the other database types, there is an audit capability in that yourecord such items asfailed login attemptsattemtped access to tables user is not authroized tochanges to databse schemachanges to permissionschanges to logins (add, delete, lock, unlock, passwrod reset)All I can find in the SQLServer documentation is the reference totracking failed logins when you set up a database, plus the Profiler'sactivities.Yes, I'm taking voer my first SQLServer database and have been asked tomake sure that this database is closely monitored for inappripriateactivity.Questions:1) Does SQLServer have this capability? (Sybase has this, which iswhere I'm coming from)2) Does SQLServer do this automatically or do I have to set up theevents to be tracked as happens with Sybase?3) What commands are there for setting up these events to be tracked?Thanks in advance!

Does 2005 have some kind of new feature that audits/monitors changes to a database kind of like an antivirus or something.
Reason for question:
1) inserting records into database, 1000 records takes about 2 minutes.
2) reading those 1000 records takes about 45 seconds
3) updating those 1000 records takes about 15 minutes
4) yes we are using ntwdblib.dll and a 4gl language
i was running a test program to add, read, update, delete 1000 records and that is when i noticed that insert, update, delete took a performance hit whereas reading didnt. i ran my test program on a control server (in house) and then at the clients side(matching OS, MSSQL 2005 SP2). Results from test program: The UPDATE process on client side took about 4x longer, INSERT about 2x longer, DELETE about 1.5x longer, READ was actually faster on the clients system.
so this made me wonder if their was some kind of database monitoring/auditing going on.
Hi
I am building a pretty simple intranet application where we need to be able to track changes to tables. The tracking feature do not need to be very advanced, we just need to see who changed something and what it was. Therefore I decided just to use a trigger based solution, but need some input/advice since my SQL skills is somewhat lacking.
Consider the following (mock-up) schema:
-- My content table
CREATE TABLE [Content](
[ContentGuid] [uniqueidentifier] NOT NULL PRIMARY KEY DEFAULT (newid()),
[Data] [nvarchar](4000) NOT NULL,
[ChangedBy] [nchar](10) NOT NULL,
[MaybeNull] [int] NULL
)
-- My history table
CREATE TABLE [History](
[ChangedTable] [nvarchar](50) NOT NULL,
[ReferenceGuid] [uniqueidentifier] NOT NULL,
[ChangedBy] [nchar](10) NOT NULL,
[ChangedOn] [datetime] NOT NULL DEFAULT (getutcdate()),
[IsDelete] [bit] NOT NULL DEFAULT ((0)),
[Changes] [xml] NOT NULL
) ON [PRIMARY]
-- My insert/update trigger
CREATE TRIGGER [RecordChangeOnInsertUpdate]
ON [Content]
AFTER INSERT,UPDATE
AS
BEGIN
SET NOCOUNT ON;
DECLARE @Changes xml
SET @Changes = (select * from [inserted] for xml raw ('Content'), elements xsinil)
INSERT INTO [History]
([ChangedTable]
,[ReferenceGuid]
,[ChangedBy]
,[ChangedOn]
,[IsDelete]
,[Changes])
SELECT 'Content', ContentGuid, ChangedBy, getutcdate(), 0, @Changes
FROM [inserted]
END
-- My delete trigger
CREATE TRIGGER [RecordChangeOnDelete]
ON [Content]
AFTER DELETE
AS
BEGIN
SET NOCOUNT ON;
DECLARE @Changes xml
SET @Changes = (select * from [deleted] for xml raw ('Content'), elements xsinil)
INSERT INTO [History]
([ChangedTable]
,[ReferenceGuid]
,[ChangedBy]
,[ChangedOn]
,[IsDelete]
,[Changes])
SELECT 'Content', ContentGuid, ChangedBy, getutcdate(), 1, @Changes
FROM [deleted]
END
I have decided to use the "one history table for all table changes" method. The changes for a row is stored in a xml column which obviously limits the total size of columns in a table being tracked, but that is not a problem in my application. In general I like this set up, since I will be able to change the schema continuously without having to change the triggers, and since the application will probably evolve a lot over the coming months this is pretty important to me.
EDIT: I should add that all the tables I will be tracking have a uniqueidentifier column. This makes it possible to related table rows in the different tables being tracked with their history.
A few concerns with the above SQL:
- Can the inserted/deleted table change between "SET @Changes = (select * ..." and the "INSERT INTO ..." statement, such that the data is not valid? If so, how to work around that?
- If I were to (hypothetically) perform a "UPDATE [Content] SET [Data] = 'something'", not only is my update trigger called once for each row updated, but the XML added to the inserted row in the history table ([History].[Changes]) represent all the rows updated in the batch update. How do I get around this?
Are there any other issues I should be aware of?
Regards, Egil.
I am setting up SQL audit on sql servers in my environment based on requirement. I want to create database specifications ASAP database created. I tried DDL trigger but Audit doesn't support triggers. So I created audit specifications on model database. the only problem with this is every specification created on new database with same name.database specification name includes newly created database name or other methods to create database specifications on newly created databases.
View 6 Replies View RelatedIn SSMS, I connect Object Explorer to a partially contained database using a contained user login with password. This user has a database role of dbdatareader. When I try to expand the Tables in the database, I get the error:

I had created 2 Sql server instance in 2 servers created using VMware. From the primary server I log shipped the required databases into the secondary. Both the servers were in the same domain whose active directory was also in another server in the same virtual lab environment. My question can we have the primary sql server in one domain and the secondary sql server to which the logs are shipped in another domain by including a router also between the 2 networks for connectivity?
View 6 Replies View RelatedI have installed new SQLServer2012 instance and my domain user have sysadmin privileges on this instance. I have a restore procedure and it will execute WITH EXECUTE AS 'domainmy username', for all the developers have exec permissions to this procedure. But newly installed server this procedure was failing with the following message. But the same procedure executing fine on other servers.

I have a script that automates some db drop/restore operations and bringing the database to single user mode is part of it: ALTER DATABASE ... SET SINGLE_USER WITH ROLLBACK IMMEDIATE...I want this to executes under a login, that has restricted privileges, so I've created a login and granted it a dbcreator role + ALTER ANY DATABASE privileges.
Problem: When I run the script against a database with an active/sleeping connection:It fails when using the restricted login: "Msg 5061...ALTER DATA BASE failed because a lock could not be placed on database ..."It completes successfully when using a sysadmin login According to stackoverflow.com the solution is to kill the active/sleeping connections to the database, before ALTER-ing it, which works fine, but the question is....
Questions: Why the "ALTER DATABASE..." statement works under the sysadmin login, but not under a dbcreator one?Does this mean the sysadmin login kills the connections to the target database in the background?Is it possible to grant additional privileges to the restricted login, so the "ALTER DATABASE..." statement won't need preventive killing of the connections?
Can I know about this ? I prefer to apply locks on database level and also to row level.
Is it possible or advicable ?
i have a development database that has updates and changes to a production database. rather than go through individually and alter all relevant tables and stored procedures, id like to back up the database on the development side and restore it on the production side as the production database. is there a way to restore the database on the production server but preserve all the security settings (ie logins and such)? i noticed on our development server, that if i try to restore the database with my development database, it overwrites the users and/or if the user is the same on both, it removes the login name for that user.
View 3 Replies View RelatedIt seems to me there are two common strategies for doing DB audit trails via a trigger:
1. On an update to a row, duplicate that row in another table with
identical rows, except for perhaps the extra columns which represent
change date and changed by. Eg. When there is an update to the Customer
table, record the changes in Customer_Audit.
2. On an update to a row, check which fields were updated. Then in a
common audit table record the table, row ID, field, previous value and
new value of the field.
I'm wondering about the pros and cons of each. More specifically, do
the pros and cons change if you are using an O/R mapper (I'm using
NHibernate.)
Some thoughts on method 1 . It seems nice for an O/R mapper, since you
could have, say, a CustomerAudit Object inherit from your Customer
object and just add the properties change date and changed by. A
problem with this is you're going to add a whole lot of objects - one
for each object which you want to audit. Another drawback is that it
could be difficult to generate a history for a particular property
which was updated. Let's say I want to see the history of changes to
the customer's status. I have to load a collection of CustomerAudit
objects (which could be costly). Then I have to iterate through them
and compare the status properties to generate a history of statuses.
This is a pretty labor instensive method if you compare it to method 2,
where the change is recorded by field, not row.
Some thoughts on method 2. It's nice since the changes are by field,
not row, which (as above) makes generating a history easy. On the other
hand, you can never have a snapshot of a particular object at a
particular point in time. Moreover, I'm not sure how foreign keys would
be handled elegantly. I record that customer.statusID changes from 3 to
6. I'd have to do a seperate join to the customerstatus table to get
meaning for 3 and 6 (which method 1 would do automatically).
Thoughts? Any preferred way to do this with an O/R mapper?
Thanks

Guys,
We looking to audit tables in the database. In the tables auditing needs to be done only on few columns not all the columns. Is there any 3rd party tool available to do it can it auditing be done on columns only with sql server 2005. Trigger doesnt work in this scenario as it works per row it does not say which column in the row was updated/inserted/deleted.
For example in the below employee table, I want to audit(history) only ssn and dob columns - all the updates/inserts/deletes made to this column should be audited.

Hi folks. I am a new DBA and working on taking over several existing MSSQL 6.5 applications.
My company needs to be able to audit the following actions on MSSQL.
login
logout
insert into specific tables
update in specific tables
delete from specific tables
I am looking for a 3rd party product that provides these services for SQL 6.5. I have found Braintree products and they have really nice auditing but for Oracle and not MSSQL. I have also looking into using triggers to build an audit log for me but the applications we are using require periodic updates that would force me to rebuild the triggers. This may cause too much administrativia.
Any Ideas?
Thanks, Aaron

Hello
I am more of a reporting person, recently I was asked to create stored procedure for an upcoming ASP.NET
application.
We have a problem that we are facing and any suggestion would be very helpfull.
The problem is that we have like 8 differtent tables each with 10 to 15 columns in it.
The front end application has pages with save , update , delete button which are insert,update,delete
for each of the 8 tables
i.e they save , update , delete these 8 tables
They want to a way to Update , this audit table which stores information
like ---
Date
User
Table
Column name
Previous column name
new column name
So for each row that was updated in those 8 tables , each column will have the above fields updated as a row of data
Initially we thought about triggers but it will be like 60 triggers ...Is there a better or other way of handling this?
Any help is appreciated
Thanks
I want to log all changes made to a table (only updates, since there will be no deletes or inserts).

What is best practise to achieve this?
