How can we achieve last month record in oracle

I am new to oracle and I am writing a query where I have to fetch last month My query:

 select to_char(sysdate,'MON') from dual

But it is giving me
AUG which is current month.
I want the output as JUL which is last month

How can we achieve last month record.

Solution 
  • select to_char(ADD_MONTHS (SYSDATE, -1),'MON') from dual 

--Move ahead one month: 
ADD_MONTHS (SYSDATE, 1);

--Move backward 1 month: 
ADD_MONTHS (SYSDATE, -1);

    Oracle Database offers several built-in functions for shifting a date by the requested amount or finding a date: 

     ADD_MONTHS—adds the specified number of months to or subtracts it from a date (or a timestamp) 
NEXT_DAY—returns the date of the first weekday named in the call to the function 
LAST_DAY—returns the date of the last day of the month of the specified date
