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 From: 'Patti Jakusz' via RBASE-L [mailto:[email protected]] Sent: Tuesday, February 14, 2017 3:38 PM To: [email protected]; RBASE-L <[email protected]>; RBASE-L <[email protected]> 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 -- You received this message because you are subscribed to the Google Groups "RBASE-L" group.
