G'day,
I've just been alerted to a strange problem with a sql script that's
been in use for years here. It contains the following statement:
SQL> l
1 select to_char(hrs_start,'DD/MM, Day') day,
2 round(Sum(nvl(hrs_end,sysdate)-hrs_start)*24,2) hours
3 FROM ACTIVITIES a,
4 hours h,
5 activity_persons p,
6 personnel per
7 WHERE a.JOB_ID = p.ACT_JOB_ID
8 AND a.ID = p.ACT_ID
9 AND h.ACT_ID = a.ID
10 AND h.ACT_JOB_ID = a.JOB_ID
11 AND h.PRS_CODE = p.PRS_CODE
12 AND h.hrs_start >= to_date (nvl(:startdate, '1-1-1900') ,
'DD-MM-YYYY' )
13 AND h.hrs_end <= nvl(to_date( :enddate, 'DD-MM-YYYY' ), sysdate)
14 AND ((per.ORAUSER=user) AND (p.PRS_CODE=per.code))
15 GROUP BY to_char(hrs_start,'DD/MM, Day')
16* ORDER BY to_date ( to_char(hrs_start,'DD/MM, Day'), 'DD/MM, Day' )
It produces a nice sorted list of the hours worked on the various days
in the given period (between :startdate and :enddate). The strange ORDER
BY clause is necessary because of the GROUP BY on to_char(..). It's
always worked nicely, for current dates as well as for previous years.
This is the expected output:
SQL> exec :startdate := '1-1-2007';
SQL> exec :enddate := '31-1-2007';
SQL> /
DAY HOURS
---------------- ----------
02/01, Tuesday 9.53
03/01, Wednesday 9.9
04/01, Thursday 7.97
05/01, Friday 8.52
08/01, Monday 8.42
09/01, Tuesday 8.52
10/01, Wednesday 8.95
11/01, Thursday .57
In the past year we migrated from 9.2x to 10.1.0.4 and the following
errors now show up when we try and produce a list for any previous year:
SQL> exec :startdate := '1-12-2006';
SQL> /
GROUP BY to_char(hrs_start,'DD/MM, Day')
*
ERROR at line 15:
ORA-01835: day of week conflicts with Julian date
SQL> exec :enddate := '31-12-2006' ;
SQL> /
GROUP BY to_char(hrs_start,'DD/MM, Day')
*
ERROR at line 15:
ORA-01835: day of week conflicts with Julian date
And julian dates aren't even asked for! Has anyone seen this before?
