RE: To_Char Problem

In your query, use and a.updated_date = (select max(updated_date) ... b) If you absolutely want to create two character strings from a date, and then compare the strings, this is the format to use: to_char (date1, 'S/MM/DD HH24:MI:SS') to_char (date2, 'S/MM/DD HH24:MI:SS') or to_char (date1, 'SMMDDHH24MISS') to_char (date2, 'SMMDDHH24MISS') -Original Message- From: karthikeyan S [mailto:[EMAIL PROTECTED]] I am using the to_char function in the following query.

RE: To_Char Problem
Why do you need the to_char? But wouldn't it work anyway with to_char(a.updated_date,'dd/mm/ hh24:mi:ss') = ( select to_char(max(updated_date),'dd/mm/ hh24:mi:ss')) which will also use the 24 hour clock instead of to_char(a.updated_date,'dd/mm/ hh:mi:ss') = ( select max(to_char(updated_date,'dd/mm/ hh:mi:ss')) Iain Nicoll -Original Message- Sent: Wednesday, August 14, 2002 5:54 PM To: Multiple recipients of list ORACLE-L Hi All, I am using the to_char function in the following query.

Re: To_Char Problem
Why would you want to do that - convert two dates into a char and then compare them ? This is not a problem but it is how char comparisions work. They are compared char by char to see which one is greater on the ASCII chart.

Re: To_Char Problem
because it is. its not a problem with oracle, its a problem with the way the query is written. make the date mask /MM/DD HH24:MI:SS instead. last i checked in math101, a number(or character string) 8 digits long, that starts with a 31 is larger than an 8 digit number starting with 01. joe karthikeyan S wrote: Hi All, I am using the to_char function in the following query.
