Tracking The History Of Changes.

Sep 11, 2006

Hi all,

I have several transaction tables on which I need to track the changes. That is I need to maitain
the history of changes. Only few column values are changed often.

Which is the best way for tracking the changes.

1.Store the whole record after the change ?

Or

2.Store the ColumnName & its respective old & new value ?

Or any other better.

Note : UI part & SP's will take care of the tracking & no plans for triggers.

Thanks in advance,

HHA

Tracking History Using Effective Dating

Apr 4, 2006

Can anyone provide me with some insight on tracking the history of my data using "Effective Dating"? I would like to keep track of an infinite history for many of the tables in my database and am trying to avoid duplicating data structures if possible.
Any advice on this topic would be appreciated, I am most interested in any links to tutorials or support articles on subject that you may know about. I have searched the web and the forums section and have not come across much.
Thanks,

Tracking Change History, By Column...

Jun 17, 2004

This one is giving me quite a bit more difficulty then I ever imagined it would...

Essentially I would like to use one table to store the change history for multiple tables. I would like to use an update trigger to check which fields have changed in each record, and write a single record for each field that changed containing the table name, field name, previous value and new value to a history table.

I can't seem to find a good way to do this.

Transact SQL :: Implementing CDC For History Tracking

Mar 1, 2012

This question is based on both T-SQL as well as SSIS. We have around 120 history tables which would be loaded with the history records from the Main tables. Following is an example of a Main table and its corresponding history table

Main table - Patient
Columns - PatientID (Identity), PatientFirstName, PatientLastName, Suffix, DOB, etc...
History table - PatientHistory
Columns - PatientHistoryID(IDentity), PatientID , PatientFirstName, PatientLastName, Suffix, DOB, etc...

So almost all of the History tables would be having the same columns from the Main table along with the identity field for the history table.

At present we have After triggers for Update which pulls the records from the deleted table and inserts these records into to history table. I have been asked to implement it without triggers.

My question is - Can we implement CDC for this and is it the best option performance wise as well

Tracking Who Is Doing What?

Aug 9, 2006

We are building an inventory management system complete with BOM. It is important to track what employee is updating what tables. Currently all such tables have a Date field that is updated when a change is made, and an EmployeeID field which records the employee making the change. I am wondering if someone knows of a better way to track this information. Any suggestions?

Tracking Searches.

May 10, 2008

Hey everybody,

First thank you for all your help thus far. Now I'm stuck again. I've been doing a lot of reading on triggers and logging information into tables but I've been trying to capture how many times someone enters an item into the search box.

So every time somebody types Gumballs into the search box I want to capture it and the name of the person who is currently logged in. Is there away to do this? Maybe this is something that I should be checking in ASP.NET forums?

Thanks in advanced guys!

Many ofthese databases never seem to have anybody connected to them in thecurrent activity.What I'd like to do is find a way to audit the logins, so everytimesomeone connects to a database it simply logs the clients IP address,what login they used, and maybe what time.

Turning RDA Tracking Off

Nov 28, 2006

I have a device application that simply needs to upload data to a server. The preferred DB server is Oracle but I've made it work using RDA and SQL Server. The problem I'm having is that it just needs to upload data, whichh I send using the RDA.Push() method. The data arrives just fine, the first time. With every subsequent upload all of the previous data is deleted fromt he server. Apparently RDA is tracking the deletion of the previously uploaded data locally and on the next .Push deleting that data from the server.

My question is: Is it possible to prevent RDA from deleting data on SQL Server? I attempted to delete the rows from the __sysDeletedRows/__sysRowTrack tables but got a "Data is read only" error.

RDA Tracking Options

Oct 4, 2007

I hoipe someone can point me in the right direction here.

I have an application with the following requirements (using SQL CE 2 alas)

A set of tables on the server that need to be imported to the handheld. Using rda, I need to get the modifications to these tables from the server (add/edit/delete) but the handheld will never update these tables.

A set of tables on the server that need to be imported to the handheld. The handheld needs to add/edit existing records, and it needs to get any changes from the server.

A set of tables on the server where the handheld needs to import a subset of the records. It needs to add (but not edit) new records, upload the new records to the server, and download any changed (add/edit/delete) records to the handheld.
What tracking options should I use in these 3 cases?

The problem comes in that I need to have some foreign key relationships in the database on the handheld. Since rda munges the names of primary keys (and indexes), I do not know of a good way to add these foreign key constraints. Any suggestions?

Thanks

Tracking Changes Best Practices

Nov 5, 2007

I've got a table that has frequent updates to it. I want 100% change tracking on this table though, so we can rollback to any previous version, or just see any changes people make.

Is there a best practice for things like this? Currently, I'm using a trigger on UPDATE to take the previous values and store them in a history table. This keeps track of who changes what, and when. Plus the most recent data is seperate and more performant to access.

I've also heard about putting an 'IsActive' flag on the main table and any changes that are made just get marked as In-Active and a new record gets added.

Any input?

Thanks!

Tracking Connections

Oct 19, 2007

Hi,

I have a bit of a problem I could do with some help with please...

I am updating an old windows client server app that uses ADO 2.8. Slowly but surely I am migrating the code from VB6 to .NET and this now means the ADO code is going to be replaced with ADO.NET.

As it is a client server the application used to establish an ADO connection and hold on to the connection for the entire duration of the app being alive. When a user signed in it would record the user logon code in a database table along with the current @@SPID value.

When the user does something in the application it typically usees an SP to do the database work. Inside the SP it also audits the work being carried out, of course the audit trail records the user id that did the work. The way it determines who called this SP is to query the logon table using the current @@SPID to get the users logon code (remember this was paired up when the user signed in).

This all worked very nicely as only one connection was ever being used and it was always the same connection that was used. However, when I come to use ADO.NET this is no longer valid. I want to use the connection pool and follow the best practices where my connections are always obtained as late as possible and released as soon as possible.

This leave me with the problem of how to get the current users logon code in to the SPs in order for them to continue writing the audit trail. Currently I am thinking that I am going to have to send the users code in to the SP as a parameter, I just wondered if there was an alternative.

Any help would be great.

Regards

Tracking Down Full Scans

Sep 21, 2001

Hi,

Full scans are bad, and I know this. I am seeing some on my database, and I know that some are unavoidable....but what I would like to do is find out which queries are causing them. I have over 500 users in my DB at any one time, and SQL Profiler doesn't seem to help me.....it shows me what objects are being scanned, but not if the scan is a full-scan or an index scan.

Does anyone have a way to find out what is causing my full scans?

Tracking Stored Procedure Use

Apr 30, 2002

Trying to determine a way to see if stored procedures are being used. I am not sure of a way to see when and if a stored procedure is being called although I have thought of using sp_recompile to set the stored procedure to recompile but I am not sure in which table that flag is set so I can see which ones were not recompiled. Any assistance or guidance would be appreciated. Thanks.
