How to compare difference between two date time stamp in Oracle SQL?

Question

I have 02 columns, TradeDate and TradeExecDate with format in dd-MMM-yy HH.mm.ss.00000000 AM/PM How do I get to find the difference between the date timestamp is greater than 01.

That is the TradeDate and TradeExecDate are different, not same date but different date.

Answer 1

As you have timestamps, the difference is an interval datatype :

SELECT *
FROM   your_table
WHERE  TradeExecDate - TradeDate > interval '1' day
