在where子句中使用sum函数

Question

I'm working with oracle fusion and one of the apps I'm working with (value-sets) does not allow me to use functions in the select statement and the from section has a 200 character limit.

This query gives me what I want but I cant use the sum with the select-

SELECT SUM(d.ABS_UNITS) from PER_ALL_PEOPLE_F b, ANC_ABSENCE_PLANS_F_TL c, 
ANC_PER_ABS_PLAN_ENTRIES d
WHERE 
d.PERSON_ID = b.PERSON_ID
AND c.ABSENCE_PLAN_ID = d.ABSENCE_PLAN_ID
AND c.name = 'FMLA LWOP'
and d.start_date between '2017-04-02' and '2017-04-15'
AND b.PERSON_NUMBER = p_num

I also tried this but had the character limit issue -

Select aa.bb from
(SELECT SUM(d.ABS_UNITS) as bb from PER_ALL_PEOPLE_F b, 
ANC_ABSENCE_PLANS_F_TL c, ANC_PER_ABS_PLAN_ENTRIES d
WHERE 
d.PERSON_ID = b.PERSON_ID
AND c.ABSENCE_PLAN_ID = d.ABSENCE_PLAN_ID
AND c.name = 'FMLA LWOP'
and d.start_date between '2017-04-02' and '2017-04-15'
AND b.PERSON_NUMBER = p_num
) aa

This approach is what I've been trying to work with putting the sum in the where clause but it's not returning anything.

Select
d.ABS_UNITS
FROM
PER_ALL_PEOPLE_F b, ANC_ABSENCE_PLANS_F_TL c, ANC_PER_ABS_PLAN_ENTRIES d
WHERE 
d.PERSON_ID = b.PERSON_ID
AND c.ABSENCE_PLAN_ID = d.ABSENCE_PLAN_ID
AND c.name = 'FMLA LWOP'
AND b.PERSON_NUMBER = pnum
and d.start_date between '2017-04-02' and '2017-04-15'
AND d.ABS_UNITS = (SELECT SUM(d.ABS_UNITS) from PER_ALL_PEOPLE_F b, 
ANC_ABSENCE_PLANS_F_TL c, ANC_PER_ABS_PLAN_ENTRIES d
WHERE 
d.PERSON_ID = b.PERSON_ID
AND c.ABSENCE_PLAN_ID = d.ABSENCE_PLAN_ID
AND c.name = 'FMLA LWOP'
and d.start_date between '2017-04-02' and '2017-04-15'
AND b.PERSON_NUMBER = pnum
)

Any input and advice would be greatly appreciated.

Answer 1

I have not work with fusion apps.
If I don't understand wrong you have limits for character limit and functions in select.

Your 'where' clause is long considering your character limit. You can shorten it using ALIAS for columns and tables in database level. Then customize your query.

Thanks for all the input I really appreciate it. I found a work around, Oracle Fusion has hidden functions in the script language I was working with that are not documented but can be found through sql. Very frustrating, but thanks for all the feed back

You can't use aggregate functions (such as SUM ) in WHERE clause, because WHERE limits rows physically. You shall aggregate in GROUP BY clause to logically limit output.
