Pass parameters to oracle plsql function - oracle

Question

I have written two queries.
query 1:
select stock_id from_id,
nvl(lead(stock_id, 1, null) over (order by stock_date),stock_id) to_id
from STOCK
where stock_time not like 'NEW_STOCK';
The above query returns result like below:
FROM_ID TO_ID
331 341
341 351
351 361
361 371
371 391
391 401
401 421
421 441
441 451
451 461
461 321
321 323
323 491
491 501
501 501
My second query is
select max(m.material_thikness) ||
' mm' || ' | ' ||
m.material_guage ||
' g' guage,
sum(util.find_usage_from_stock(MATERIAL_THIKNESS,P_FROM_ID,P_TO_ID)) -
sum(util.find_sheets_sold(MATERIAL_THIKNESS,P_FROM_ID,P_TO_ID)) diff
from material m
where m.active like 'Y'
group by m.material_guage
order by m.material_guage;
The above query returns results like below:
GUAGE DIFF
6 mm | 11 g 0
4 mm | 12 g -0.32
3 mm | 13 g 0.51
2 mm | 14 g 0.85
1.5 mm | 16 g -0.41
1.2 mm | 18 g 0.35
1 mm | 19 g 1.67
.8 mm | 20 g 0
I need to add FROM_ID and TO_ID return from my first query into P_FROM_ID and P_TO_ID in my second query and I need to modify my second query to get results like below.
RANGE DIFF
331-341 0
341-351 0.35
351-361 0.45
.......
441-451 1.25
451-461 -0.75
461-321 1.67
How could I do that ?

Answer 1

If you want to get values for every material_thikness for all the p_id intervals then:
select s.from_id || '-' ||s.to_id range,
sum(util.find_usage_from_stock(MATERIAL_THIKNESS,s.from_id,s.to_id)) -
sum(util.find_sheets_sold(MATERIAL_THIKNESS,s.from_id,s.to_id)) diff
from material m, (select stock_id from_id,
lead(stock_id, 1, stock_id)
over (order by stock_date) to_id
from STOCK
where stock_time not like 'NEW_STOCK') s
where m.active like 'Y'
group by s.from_id,s.to_id
order by s.from_id;

Answer 2

Are you looking for something like this:
select max(m.material_thikness) ||
' mm' || ' | ' ||
m.material_guage ||
' g' guage,
sum(util.find_usage_from_stock(MATERIAL_THIKNESS,P_FROM_ID,P_TO_ID)) -
sum(util.find_sheets_sold(MATERIAL_THIKNESS,P_FROM_ID,P_TO_ID)) diff
from material m
where m.active like 'Y'
and (m.p_from_id,m.p_to_id) in(select stock_id from_id,
nvl(lead(stock_id, 1, null)
over (order by stock_date),stock_id) to_id
from STOCK
where stock_time not like 'NEW_STOCK')
group by m.material_guage
order by m.material_guage;
Will that do it?
