my problem is trying to use a SELECT statement and order the top 10 by a certain column. I managed to compile something after searching through lots of forums, however I need to confirm that the timestamp in one field is within the last week. I have gotten this to execute however i’m not sure whether this is correct as I can’t print the value for the where clause:

SELECT itemid, count(itemid) 
FROM Rateddate 
WHERE TO_CHAR(CURRENT_TIMESTAMP - DATE_RATED) < TO_CHAR(7)  
GROUP BY itemid;

TLDR:

TO_CHAR(CURRENT_TIMESTAMP - DATE_RATED) < TO_CHAR(7)

does this make sure the date_rated timestamp is less than a week old?

    It would make more sense to say

    WHERE date_rated > sysdate - interval '7' day

    if you want data from the last 168 hours. You may want

    WHERE date_rated > trunc(sysdate) - interval '7' day

    if you want data from any point in the day 7 days ago rather than caring about what time of day it is currently.
