I believe here is what’s missing:

AND (TO_DATE(SUBSTR(TO_CHAR(FIRST_TIME, ‘MM/DD/RR HH:MI:SS’), 1, 8),
‘MM/DD/RR’) < = TO_DATE(&END_DATE, ‘DD-MM-YYYY’))

Just make sure you put code between <pre> and </pre> because if you don’t, and you do not escape special html characters, you will get unexpected results.

I think this form cut the end. So replace end with this: FROM V$LOG_HISTORY A WHERE (TO_DATE(SUBSTR(TO_CHAR(FIRST_TIME, 'MM/DD/RR HH:MI:SS'), 1, 8), 'MM/DD/RR') >= TO_DATE(&BEGIN_DATE, 'DD-MM-YYYY')) AND (TO_DATE(SUBSTR(TO_CHAR(FIRST_TIME, 'MM/DD/RR HH:MI:SS'), 1, 8), 'MM/DD/RR') Sorry that is it. I think this form cut the end. So replace end with this:

FROM V$LOG_HISTORY A
WHERE (TO_DATE(SUBSTR(TO_CHAR(FIRST_TIME, ‘MM/DD/RR HH:MI:SS’), 1, 8),

AND (TO_DATE(SUBSTR(TO_CHAR(FIRST_TIME, ‘MM/DD/RR HH:MI:SS’), 1, 8),
