I don't know a way to edit 2 tables in 1 SQL statement. If you have 2
sql statements then the performance should be almost the same with the
function and maybe slightly worse with a trigger.

Hi Julius Tuskenis,
Many thanks for helping me. These are good solutions. But I have some
doubts
Look below

I would suggest you 2 solutions:
1. to use a function to edit these fields. That way you will be sure
that you will not forget to update both tables.
2. use a trigger on master table. If I understand you - the history
table could be filled using trigger, when data in master table changes.
That way you could change only master table in your application.
I think having triggers would bring performance down. So instead can
we have single
sql update statement to update all four fields of two tables? Just a
crazy idea.
Good luck!
Thanks for the wish.
These wishes needed to implement smart solution to above problem :)
