Rathish,

What you want to use is ‘D’ instead of ‘day’ like in the following example (which was run today, wednesday.)

SQL> select to_char(sysdate, ‘D’) from dual;

T
-
4

UNIX gurus should be careful since cron starts numbering Sunday as 0 and Oracle starts at 1.

We can get the day as Sunday, Monday etc by using
SELECT to_char(sysdate,’day’) FROM dual

But is it possible to get the day of date as number? That is Sunday as 1, monday as 2 etc….

pls help…..
Rgds,
Rathish.

Sandeep, you have a couple things going wrong here. First, the date you're working with will need to be converted into the Oracle date format with a TO_DATE first like this: TO_DATE('5/5/2006 9:54:33 AM', 'MM/DD/YYYY HH:MI:SS AM') Once you've done that you could just use a to_char to view just the month part like this:

SELECT TO_CHAR(TO_DATE('5/5/2006 9:54:33 AM', 'MM/DD/YYYY HH:MI:SS AM'), 'MM/DD/YYYY') FROM DUAL;

05/05/2006

Now if you want to do this with the TRUNC function you'll want to apply it around the TO_DATE function.

SELECT TO_CHAR(TRUNC(TO_DATE('5/5/2006 9:54:33 AM', 'MM/DD/YYYY HH:MI:SS AM')), 'MM/DD/YYYY HH:MI:SS AM') from dual;

05/05/2006 12:00:00 AM

Here we see that the trunc command doesn't remove the hour/minute/second from the date, but rather it sets them to midnight. Let me know if this helps.

[...] The best way to assure a job will run at a specific time every day is to truncate the date and add a number of hours to it. I have explained this in greater detail in a separate article Getting a Specific Time of Day in Oracle. [...]
