Trong SQL * Plus , bản trình diễn của tôi nằm giữa các ngày '2012-01-01' và '2012-02-20' :
SQL> def date_start = '2012-01-01'
SQL> def date_end = '2012-02-20'
SQL>
SQL> WITH DATA AS
2 (SELECT to_date('&date_start', 'YYYY-MM-DD') date1,
3 to_date('&date_end', 'YYYY-MM-DD') date2
4 FROM dual
5 )
6 SELECT TO_CHAR(date1+LEVEL-1, 'fmMonth') month_name,
7 TO_CHAR(date1+LEVEL-1, 'fmDay') day_name,
8 TO_CHAR(date1+LEVEL-1, 'IW') the_week,
9 TO_CHAR(date1+level-1, 'D') the_day
10 FROM data
11 CONNECT BY LEVEL <= date2-date1+1
12 /
old 2: (SELECT to_date('&date_start', 'YYYY-MM-DD') date1,
new 2: (SELECT to_date('2012-01-01', 'YYYY-MM-DD') date1,
