halfway down a set order

Hi Foxgang

I am going round the bend with this. Situation. I have a file with dates in

(datetime). The dates are not in order, and have a couple of idiots inputs

including a year 2210 one plus a jan 2013 when it should be jan 2014.

Anyway most are good and in a range.

So what I want to do is set the order to the date (actually a datetime

fields) ok no problem.

Now I want to see what's halfway down. But....

Goto recount()/2 takes me to halfway down the original order which could be

an early date (and is in the file I am trying to sort out). So the question

is how do I find the halfway point in an ordered table. In other words in

this case, halfway down the datetime field. No good looking at min and max

as due to the idiot input of 2210 it turns out to be 2107. I cannot assume

dates as these files are ongoing.

I've got over it with this by select distinct (datetime) order by (datetime)

and going halfway but I am curious how halfway down an ordered table can be

achieved

Al
