Hi.
Let Me explain better:

I have to do some calculations or every day in a range of 60 years.
Insert in a table the calculations of 1 day, delete it and pass to the
next day.

I must reiterate it .
One calculation takes 3 seconds.
But after the database reached more than 50 mega SLOWWWWWWWWWWWW DOWN.
too much.

I have done this either in Sp and Delphi, same results, an
inacceptable growing...

Thanks

Arn
