Fw: Clipping values

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In response to a private email from someone else on this list, I thought I should send the following clarification.

I have a table with four values which are constantly lowered by user action. These four values must rise over time, in five minute intervals.  The core of the function, in pseudo-code, would look something like this:

  FOREACH row IN SELECT * FROM some_table WHERE some_percentages are less than 1
  LOOP
      new_percentage = num_intervals * .1 > 1 
          ? 1 
          : num_intervals * .1;
      UPDATE some_table SET some_percentages = new_percentage WHERE id = row.id
  END LOOP

But, of course, doing that for four percentages (with at least one having a different increment value than .1)

Cheers,
Ovid
