Hy, im evaluating how to implement Audit trail in a multi-tier .NET 3.5 Database driven Webapplication based on nettiers and SQL-Server 2008.
I read a lot about the subject, but im still not sure whats the easiest way to do it.
Is it possible at all to implement it (without refactoring everything) with the entity framework if the rest of the application never used the EF?
Or do you guys think, that triggers would do the job just fine?
Ah, and a 2nd question: Do I get this right, that frameworks like log4net are just for logging debug-infos and not for audittrail?
thanx a lot for any input!

Sorry, stopped reading at this point. Anyone who has positive thoughts about triggers needs to be taken out and boiled in oil, shot, drawn and quartered and then made to support the abomination they have created. I hate triggers.
I know they are the "recommended" solution to this problem but I still hate em. I have also never had to implement a really stringent auditing solution. You also need to define the level of auditing you need to do. We usually settle for a log of who changed the record and when, tracking from and to data is whole nother level of nasties.

I worked on a system that had some quite strict auditing requirements and the way we managed it was to lock down the tables in the database so that only DBAs had direct update access to the tables. Any updates to the tables by anyone else had to be via stored procedures. Built in to every stored proc was a bit of code that wrote out the audit history of what was happening (which table, which columns, old data, new data, date and time, user id, etc.).
But it sounds as if you want to keep the impact on your existing system to a minimum, in which case you may end up having to use triggers as the least painful option.
As for log4net, it is a generic logging system that can log pretty much anything you want it to log about the behaviour of your system. You can use it to log debug info, you can also use it to log error conditions for later investigation, you can also use it to log configuration information at system start up, anything you want. I suppose you could use it as part of an audit system in your application, depending on what your requirements were and how strict it needed to be.

we can get an encrypted text by using the below keyword
DBMS_UTILITY.GET_HASH_VALUE in oracle
I need to decript the particular string passed to this keyword
for Eg:
SELECT LTRIM (TO_CHAR ( DBMS_UTILITY.GET_HASH_VALUE ( 'ADMINISTRATOR',2,1048576))) FROM dual;
this will return the encrypted text of 'ADMINISTRATOR' as 121216
But to get the Decryption of that 121216 as 'ADMINISTRATOR'.. is there any keyword used in oracle??
Please help me out..
Thanks in advance..

Hashing is not encryption, hashing is a reduction in size, somewhat like an executive summary; it implies throwing away information, hence a one-way operation.
A common practice is to hash passwords and store the result, not the password itself. To check an incoming password, calculate its hash, and compare against the expected hash. No way to retrieve the password, it isn't there at all.

Hi guys
I have two fields, FirstName and LastName. I am able to concatnate both names but if one of the name is null then I don't get the results. For example, First name is John and there is no last name then upon concatanting both names i get null.
I have set the database "Concatenate Null yeilds Null" to True but still no success. Perhaps, could anyone of you help me.
Thanks

It sounds like this is doing exactly what you told it to. You could:
1) follow i.j.russell's suggestion and use COALESCE, [edit - added]
2) try changing the setting,
3) write code that tests for Null and handles the various cases, or
4) don't allow Null values in these fields.
Looking through the list, i.j.russell's suggestion sounds very good to me.
Please do not read this signature.

For MS SQL Server I use ISNULL like ISNULL(FirstName + ' ', '') + ISNULL(LastName, '') I put a space after the first name but if it is null then the space does not get added.

Hi everOne
I have used switch case statment before but not sure the way I want to use it is implementable or not. If it is then please could you convert the following code into switch Case statement.
create proc Details_GetBYID
(
@Id int,
@TypeId nvarchar(max)
)
AS
IF @TypeId = 'P1'
BEGIN
SELECT motot.Completed,motot.Hours,motot.Subject
FROM MasterT as motot
INNER JOIN PSALevel as psal on psal.Id = motot.Id
WHERE motot.Id = @Id
END
ELSE IF @TypeId = 'P2'
BEGIN
SELECT motot.Completed,motot.Hours,motot.Subject
FROM MasterT as motot
INNER JOIN PSALevel as psal on psal.Id = motot.Id
WHERE motot.Id = @Id
END
ELSE
BEGIN
SELECT motot.Completed,motot.Hours,motot.Subject
FROM MasterT as motot
INNER JOIN PSALevel as psal on psal.Id = motot.Id
WHERE motot.Id = @Id
END
any help would be appriciated.
thanks in adv.

Hello Folks,
I'm using powershell in conjuction with the Outlook Redemption library in an attempt to import messages already present in a folder on the desktop. Although, the code gives no errors, I just don't see the end result of the message being in the inbox. The code being used is as follows:
-----------------------------------------------
$outlook = New-Object -COM Outlook.Application
$routlook = New-Object -COM Redemption.RDOSession
$routlook.Logon
$routlook.MAPIOBJECT = $outlook.Session.MAPIOBJECT
$msg = $routlook.GetDefaultFolder(6).Items.Add(0)
$msg.Import("c:\test.msg", 1024)
$msg.save
$routlook.Logoff
-------------------------------------------------
Any help will be appreciated.
Thanks.

I'm sure that there is a more appropriate forum for this question to be in.

Is there any benefit in setting a primary key in a table variable? Especially if you will perform SELECT and INSERT operations on it?
Like,
DECLARE @Tbl TABLE(Id INT PRIMARY KEY, Name NVARCHAR(36))
