Compare changes in a datasource after a certain time

Compare changes in a datasource after a certain time

How I can compare changes in my datasource after a certain while?

 

Let's say there is a table with 3 columns like in this small example.

At time=t0 we have this result:

11-06-_2019_16-01-59.png

 

 

After a while at time=t1 some values have changed (in this case amount and price).

11-06-_2019_16-05-21.png

 

I think I need a temporry table where I can store a status or sth like that.

But which components do I have to use to compare the changes?

 

In the output I only need the rows which were changed.

 

Thanks for any advice.

Re: Compare changes in a datasource after a certain time

did you have a key?
can you set trigger to log changes?
what is compare changes for you?
do you want to store data?
did you have update time?
there is a lot of questions…..
