Home -> Community -> Mailing Lists -> Oracle-L -> Re: DECODE HELP
Why use decode. Look up the "greatest" sql function.
select prim_key, greatest(first_date,sec_date,third_date) from your_table.

Please respond to
ORACLE-L
Hello all,
This has probably been discussed here before and I'm sorry if I'm repeating this. But I'd very much appreciate if someone could show me how to use DECODE to select a MAX date where records are like this:
PRIM. KEY FIRST_DATE SEC_DATE THIRD_DATE JO001599O 12/14/2000 03/23/2001 05/21/2001 JO001620L 12/27/2000 05/16/2001
The first_date, sec_date and third_date may or may not exist; either one of the dates will be there. I need to come up with another column LATEST_DATE which will show the latest date of the 3.
Thanks very much in advance!
