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.

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:rbase-l@googlegroups.com] Sent: Tuesday, February 14, 2017 3:38 PM To: rbase-l@googlegroups.com; RBASE-L <rbas...@rbase.com>; RBASE-L <rbase-l+nore...@googlegroups.com> 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.
