SQL*Plus Spool Oracle ( Subquery /With Clause Issue) - oracle

Question

Can you please help me ?
when I execute the .sql file below in Toad, it gives me the expected results.
with
a as(select extract(year from sysdate)var_year,to_char(sysdate,'mm-dd')var_day from dual),
b as(select case when var_day between '10-01'and '12-31'
then to_date(var_year||'-10-01','yyyy-mm-dd')
else to_date(var_year-1||'-10-01','yyyy-mm-dd')end d1,
case when var_day between'10-01'and'12-31'
then to_date(var_year+1||'-09-30','yyyy-mm-dd')
else to_date(var_year||'-09-30','yyyy-mm-dd')end d2
from a)
select * from b,SCHEMA.TABLE1
where SCHEMA.TABLE1.DATE_FRAIS between b.d1 and b.d2;
But when I Try to launch it using a .cmd job adding a spool function, the console opens but nothing happens and the console stay open. The .csv file is generated but nothing inside.
Please find below Script not working (spool succeeded but without content):
SET FEEDBACK OFF
set heading on
SET PAGESIZE 0
SET LINESIZE 8000
set pagesize 50000
SET COLSEP ";"
COLUMN dcol new_value mydate noprint
select to_char(sysdate,'YYYY_MM_DD') dcol from dual;
SPOOL test.csv;
with
a as(select extract(year from sysdate)var_year,to_char(sysdate,'mm-dd')var_day from dual),
b as(select case when var_day between '10-01'and '12-31'
then to_date(var_year||'-10-01','yyyy-mm-dd')
else to_date(var_year-1||'-10-01','yyyy-mm-dd')end d1,
case when var_day between'10-01'and'12-31'
then to_date(var_year+1||'-09-30','yyyy-mm-dd')
else to_date(var_year||'-09-30','yyyy-mm-dd')end d2
from a)
select * from b,SCHEMA.TABLE1
where SCHEMA.TABLE1.DATE_FRAIS between b.d1 and b.d2;
SPOOL OFF
Whereas, when I launch a "simple" .SQL file by a .cmd job adding a spool function, it works (maybe because I removed "CASE" ?).The .csv file is generated and there is content inside
Please find below an example of Script working (spool succedeed with content) :
SET FEEDBACK OFF
set heading on
SET PAGESIZE 0
SET LINESIZE 8000
set pagesize 50000
SET COLSEP ";"
COLUMN dcol new_value mydate noprint
select to_char(sysdate,'YYYY_MM_DD') dcol from dual;
SPOOL test.csv;
with
a as (select extract(year from sysdate) var_year1, extract(year from sysdate) var_year2, to_char(sysdate) var_day from dual)
select * from a;
SPOOL OFF

Answer 1

I suspect that (a) you've run this as sqlplus -s user/pass #script and don't have an exit at the end of your script, which will cause the command window to stay open; and (b) you don't have any committed data in your table for this year's date range. You would see that effect if you added data in your Toad session and ran your query there, but did not commit those changes - the newly-inserted data would not be visible to any other session in that case, so your SQL*Plus query wouldn't see it. And since you have feedback off, you wouldn't even see 'no rows selected`.
#boneist's simplification is cleaner and simpler than mine, but I'll leave this to show the CTE and non-CTE, and the between and >=/< variations.
Incidentally, you can simplify your date calculation quite a bit, to something like:
with b as (
select add_months(trunc(sysdate, 'YYYY'),
case when extract(month from sysdate) < 10 then -3 else 9 end) d1,
last_day(add_months(trunc(sysdate, 'YYYY'),
case when extract(month from sysdate) < 10 then 8 else 20 end)) d2
from dual
)
select *
from b
join table1 on table1.date_frais between b.d1 and b.d2;
You can see the start and end dates the CTE would generate for various dates with this demo. I think that's what you're after, if I've interpreted your current query properly. (And here is the same query with #boneist's simplification).
Or if you don't really want to show the date range as well as the actual data from table1, move the calculation into the filter:
select * -- but still better to list the columns
from table1
where date_frais >= add_months(trunc(sysdate, 'YYYY'),
case when extract(month from sysdate) < 10 then -3 else 9 end)
and date_frais < add_months(trunc(sysdate, 'YYYY'),
case when extract(month from sysdate) < 10 then 9 else 21 end);
I've also changed this version from between to use >= and <, and pushed the end-date out by a day; that will include any values on the last day of the final month which have a time after midnight (which I see #boneist also commented on). If your dates are all midnight then between would work, but I still prefer this explicit pattern, and it makes the month adjust calculation a little more obvious too I think.

Answer 2

Could it be simply that your query takes a long time to retrieve all the results, and you haven't left it long enough? You might see results in Toad, but have you tried going to the end of the resultset, rather than just getting the first 500 rows (or however many you have set Toad to retrieve per fetch).
I doubt the issue is anything to do with the WITH clause. In any case, there is no need for it; you can simply manipulate sysdate like so, in order to get your results:
select *
from SCHEMA.TABLE1 t1
where t1.DATE_FRAIS between add_months(trunc(add_months(sysdate, 3), 'yyyy'), -3)
and add_months(trunc(add_months(sysdate, 3), 'yyyy'), 9) -1;
N.B. I hope your DATE_FRAIS column has no time elements to it, otherwise you'll be missing anything that's after midnight on the 30th September of each year.
