Patti, Buddy beat me to it but sometimes when we are using an older database,
we actually saved a space for a null so you may need to check to see if you
actually have nulls. Jan

Patti You might want to try something like this depending on how you want
to hand null dates. It my example I’m saying if date is null then make it
12/31/2999 or whatever date you want. …. OldestDate =
(LMAX((IFNULL(DATE1,12/31/2999,DATE1)),(IFNULL(DATE2,12/31/2999,DATE2)),(IFNULL(DATE3,12/31/2999,DATE3))))
I didn’t test this so make sure to test on a copy of database Buddy

Subject: [RBASE-L] - problem with null values Hello, I'm using Rbase 10.
I'm trying to update one date column in my table to be the oldest of 3 other
date columns. My command is: update Table1 set OldestDate = (LMAX(date1,
date2, date3)) But it only works if all three dates have values. I have
zero set on. I tried setting on Eqnull. But I only get a blank if one of the
dates is null. Is there another setting to turn on? Thanks, Patti --
