How to get delete/Update row + SQL

Mycroft Holmes

As Eddy has said, you need to address your requirements first! Attempting to retain every change, both from and to via the .ldf is not going to work. Eddies suggestion that you make copies of records instead of updating is valid (I have used this under duress), marking deleted records as Disabled is also a recognised solution. Go back to your requirements and reassess them in the light of what you have learned over the last few weeks trying to use the wrong design to achieve a desired result.

Never underestimate the power of human stupidity RAH

I get Old Value and New Value u can see the red color part:OldName,OldFamily--->UpdatedName,UpdatedFamily via this trace :

As stated you are going at it from the wrong direction. Other solutions include: - using the OUTPUT Clause[^] - using trigger[^] both can track the data. If the code cannot be changed the trigger would be the way to go.

What does the trigger-solution provide, besides extra trouble in maintainability? We're not synchronizing on every record, and he merely needs a duplicate. Changing the command being executed would be a tad more efficient than adding triggers here to copy each and every reveived value to another table (with the same structure).

Since you can put logic in a trigger to only pull what you want this could create the table of updated columns. I did say that trigger might be better if the main code could not be changed.

Lost User

I know that it's possible, the question was whether it would be a good idea :) ..but agreed, if they can't change the application-code, then one would have to make a change in the database-server.

If you run it manually, you'll see the text as sent to the server. A trace is meant to "trace" what commands are being executed. AFAIK, it wouldn't even remotely interested in the "current" values. Repeating the question will not change the answer.

May I offer a possible solution, if all of the database actions are being "called" by a front end application then another method to maintain an audit trail is to simply append and database change details to a ascii log file (simple text file). :) For example where I work if anybody makes a change to any database field the action is recorded also to the log file. Then if we need to access who made the changes and what changes were made on any particular date in time, even years ago it's a simple matter to check the log file. When it get's too big archive it and start a new one. :cool:

jojoba2011

Thanks all for Reply. Can u give me a small example on how to do that? I exactly wanna this.

jojoba2011

thanks for you reply for both C# and Database pages. But isnt it possible to have when running update SP. Its very important to do that . if possible then its end of story. Q2)is it possible to have the OLD trace if the user delete the .trc file from SQL.

JohnPayton

Sure, this is a snippet from a routine in VB6, but it would be easy to convert it to VB.Net. In this instance I'm recording the method of payment and amounts from each transaction. If the log.txt file does not exist then create it, otherwise append to it. You will notice this particular log file is called LogReturns.txt and it's in the root directory of the program executable. Hope this is what you are looking for.

On Error Resume Next
Dim fso As New Scripting.FileSystemObject
Dim mFile As String
Dim txtfile As Object
mFile = "/LogReturns.txt"
If fso.FileExists(App.Path & mFile) Then
Set fso = CreateObject("Scripting.FileSystemObject")
Set txtfile = fso.OpenTextFile(App.Path & "/LogReturns.txt", ForAppending)
Else
Set fso = CreateObject("Scripting.FileSystemObject")
Set txtfile = fso.CreateTextFile(App.Path & "/LogReturns.txt", True)
End If
Dim mVar As Integer
txtfile.WriteLine (" ")
txtfile.WriteLine ("Receipt Number : " & recReceipt.Fields("ReceiptNum"))
txtfile.WriteLine ("Member Number : " & recReceipt.Fields("MembNum"))
For mVar = 0 To intMoviesReturnCount - 1
txtfile.WriteLine ("Movie Number(s): " & arrMoviesReturned(mVar))
Next mVar
txtfile.WriteLine ("Rec Date & Time: " & recReceipt.Fields("ReceiptDateTime"))
txtfile.WriteLine ("Amount Payable : " & Format(recReceipt.Fields("Amount"), "$0.00"))
' v1.0.159 : 26-Jul-2006 : JPG : Added CashNett value to report
txtfile.WriteLine ("Cash Nett : " & Format(recReceipt.Fields("CashNett"), "$0.00"))
txtfile.WriteLine ("Cash Tendered : " & Format(recReceipt.Fields("CashTendered"), "$0.00"))
txtfile.WriteLine ("Eftpos Selected: " & Format(recReceipt.Fields("Eftpos"), "$0.00"))
txtfile.WriteLine ("Cheque Provided: " & Format(recReceipt.Fields("Cheque"), "$0.00"))
txtfile.WriteLine ("Credit Card : " & Format(recReceipt.Fields("CreditCard"), "$0.00"))
txtfile.WriteLine ("GiftCard Used : " & Format(recReceipt.Fields("GiftCardUsed"), "$0.00"))
txtfile.WriteLine ("Discount : " & Format(recReceipt.Fields("Discount"), "$0.00"))
txtfile.WriteLine ("Transfer : " & Format(recReceipt.Fields("DebitMemberBalance"), "$0.00"))

txtfile.WriteLine (" ")
txtfile.WriteLine ("\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*")
txtfile.Close
Set fso = Nothing

thanks for ans. But i wanna to get the info from my SQL database . i wanna to have every thing the user changed,Updated,Inserted,Deleted. So i can trace that.

JohnPayton

Hi jojoba2011, You get the values you need to save from the front end application, what I mean to say is the values you are using in the database insert or update query are also used for the text report audit trail. In the case of the original values that are being replaced, they are stored as a variable when the update/insert page is first populated. Do you understand what I'm saying?

jojoba2011

first of all thanks for your attention! Sorry i cant understand! I think that u add values to txt when inserting them to Database. Correct? But i wanna to get it from DB.even if the text file deleted i can get info back.

No, not possible.

Yes, as I already suggested when I answered the post; embed a trace-file as an embedded resource. That way it will be compiled "into" your executable. ..but no, unless you're the administrator and have more rights on my machine than I do, I'll not only change the trace-file, I'll even make sure that there's fake data entered for your amusement.

jojoba2011

thanks, your really active one. can you give me an example that how can i embed a trace-file as an embedded resource in C# in my app.???

Lost User

I could, but it's your work. There are enough examples on the internet, and they don't take more than a few lines of code. Good luck :)

Bastard Programmer from Hell :suss:

JohnPayton

Yes that's right, you keep the values you are inserting/updating/deleting then call a routine to record the changes in the ascii text audit file. :) Re Getting data from the DB, I'm sorry but I don't know how to retrieve data from SQLServer from past transactions, I'm sure it's possible from the transaction log. But in my circumstances it's been easier to just store the old values and new values when they happen to variables then send to the ascii log file.

jojoba2011

thanks! but i wanna to have that .how to retrieve data from SQLServer from past transactions

jojoba2011

Hi,Thanks i wanna to have something like "ApexSQL Log" but not that much big.
