RE: High values
John, Look at the DECODE statement. You can use it in the ORDER BY clause. I would *never* insert a garbage value into a database column as you are talking about. How do you determine if it is truely garbage? You know of course, if you selected a high values value today, that next month that value would be valid, so you would end up updating the column to something else. An order by using DECODE could look like: ORDER BY DECODE(number_column,null,999,number_column) or ORDER BY DECODE(char_column,null,'',char_column) hope this helps Tom Mercadante Oracle Certified Professional -Original Message- Sent: Friday, September 20, 2002 5:18 AM To: Multiple recipients of list ORACLE-L Basically what I want to do is put a value in a VARCHAR2 column that will ensure it appears as the last row when selected using an ORDER BY on the column John -Original Message- From: DENNIS WILLIAMS [SMTP:[EMAIL PROTECTED]] Sent: 19 September 2002 21:09 To: Multiple recipients of list ORACLE-L Subject: RE: High values John - Since nobody has replied to your question, I discussed it with a fellow COBOL programmer.
