Comapring old data and updated data and highlight the updates

Hi Friends,

I was trying to do something fancy and got stuck.

I am pulling data from few excel sheets and those sheets get updated from users on daily basis. They may add data or may update the old data or may delete data. So I used to consolidate all the data together into one sheet.

Is there any way by which I can detect the updates which was done by the user today from the data loaded at the time of previous load?

Any help on this will be really appreciated.

Thanks and Regards

Create qvd daily; compare yesterday's qvd data with the excel data to be loaded today. To do this there has to be a unique identifier of the record i.e. primary key. But here without the timestamp you might not be able to implement effective incremental load(which you possibly are not looking for).
