Sqlite: subtotals in own row aka "rollup"

Question 1

Here is a way that works to emulate rollup under sqlite. I stumbled upon an answer from 2007 on a database forum asking about subtotals and grand totals. I'll summarize here with my simplified case.

I have a table stocks which contains Ticker_Symbol(Text), Underlying(Text), and Quantity(Integer) among other fields. Those suffice for this example.

Rollup can be emulated by using the following call from sqlite:

select Ticker_Symbol,Underlying,Quantity from (
select '1' orderCol, Ticker_Symbol,Underlying,Quantity from stocks 
union  
select '2' orderCol, Ticker_Symbol, 'Subtotal' as Underlying, Sum(Quantity) as Quantity from stocks 
group by Ticker_Symbol 
union 
select '99' orderCol, '_' as Ticker_Symbol, 'GrandTotal' as Underlying, sum(Quantity) as Quantity from stocks) 
as t1  order by case  when orderCol=99 then 1 else 0 end, Ticker_Symbol, orderCol;

This produces output similar to below:

|Ticker_Symbol      |Underlying|Quantity|
|-------------------|----------|--------|
AAPL                 AAPL         500
AAPL                 AAPL        1000
AAPL                 AAPL        2000
AAPL                 Subtotal    3500
AAPL140222P00500000  AAPL          10
AAPL140222P00500000  Subtotal      10
IBM140322C00180000   IBM           25
IBM140322C00180000   Subtotal      25
R140222C00067500     R             10
R140222C00067500     Subtotal      10
VLCCF                VLCCF        300
VLCCF                VLCCF       2000
VLCCF                Subtotal    2300
_                    GrandTotal  5845

Unfortunately, I could not find a way to avoid using the Ticker_Symbol. Ideally, it would be nice to just replace the current Ticker_Symbol with 'Subtotal' (or GrandTotal) but that does not work. Also note the use of the "_" to assure that GrandTotal does indeed show up on the last row.

I hope this helps others and if anyone out there has a way of making it better, please add.

Question 2

Had a same problem myself - emulating subtotals in SQLite3, and here`s, what I came to:

with counter(numm)as(select 1 union all select numm+1 from counter where numm<34),
str(par,node)as(select 1, numm from counter where numm in(2,5,8,11)union 
select 11, numm from counter where numm in(12)union 
select 12, numm from counter where numm in(13,17,20)union 
select 13, numm from counter where numm in(14,15,16)union 
select 17, numm from counter where numm in(18,19)union 
select 2, numm from counter where numm in(3,4)union 
select 20, numm from counter where numm in(21)union 
select 21, numm from counter where numm in(22,23)union 
select 5, numm from counter where numm in(6,7)union 
select 8, numm from counter where numm in(9,10)union 
select null, numm from counter where numm in(1)),
struct(par,node,clevel)as(select par,node,0 from str where par is null union all select c.par,c.node,s.clevel+1 from str c join struct s on s.node=c.par)/*struct*/,
namez(namee,node)as(select 'Grandtotal', numm from counter where numm in(1)union
select 'Subtotal1', numm from counter where numm in(2)union
select 'Subtotal2', numm from counter where numm in(5)union
select 'Subtotal3', numm from counter where numm in(8)union
select 'Subtotal4', numm from counter where numm in(11)union
select 'Subtotal5', numm from counter where numm in(12)union
select 'Subtotal6', numm from counter where numm in(13)union
select 'Subtotal7', numm from counter where numm in(17)union
select 'Subtotal8', numm from counter where numm in(20)union
select 'Subtotal9', numm from counter where numm in(21)union
select 'value10', numm from counter where numm in(18)union
select 'value11', numm from counter where numm in(19)union
select 'value12', numm from counter where numm in(22)union
select 'value2', numm from counter where numm in(4)union
select 'value3', numm from counter where numm in(6)union
select 'value4', numm from counter where numm in(7)union
select 'value5', numm from counter where numm in(9)union
select 'value6', numm from counter where numm in(10)union
select 'value7', numm from counter where numm in(14)union
select 'value8', numm from counter where numm in(15)union
select 'value9', numm from counter where numm in(16)union
select 'valueN', numm from counter where numm in(23)union
select 'vaule1', numm from counter where numm in(3)),
some_random_values(node,val)as(
select node,
case node 
  when 3 then 10 when 4 then 33 when 6 then 123 when 7 then 2 
  when 9 then 321 when 10 then 202 when 14 then 2 when 15 then 88 
  when 16 then 56 when 18 then 17 when 19 then 345 when 22 then 99 when 23 then 9 
  else 0 
end from str),
sval(par,node,val)as(select s.par,s.node,a.val from str s join some_random_values a on a.node=s.node),
recur(par,node,val)as(
select * from sval where par in(select par from str group by par having(node)>1)
union all
select b.pAR,b.node,a.val+b.val
from recur a join sval b on b.node = a.par)
select s.par,s.node,substr('                            ',1,s.clevel*5)||n.namee name,v.val
from struct s join namez n on n.node=s.node
join(select par,node,sum(val)val from recur group by 1,2)v on v.node=s.node
order by s.node

Example might look a bit complicated. Main part starts with recur(par,node,val).

Runs fine on SQLite 3.9.1.

Question 3

I used it following way with reference from TrustNoOne's Answer .

    select securityname,bal,Total from (
select 1 orderCol,sectorname, '#' || COALESCE (sectorname,'') as securityname ,'' bal ,'' as Total from tablename 
group by sectorname  --Title
union 
select 2 orderCol,sectorname, securityname,bal,'' from tablename --Items
union  
select 3 orderCol,sectorname, sectorname || '- Subtotal :' as securityname ,'',Sum(bal) as Total from tablename 
group by sectorname --SubTotal
union 
select 99 orderCol,'_' sectorname, 'Grand Total :' as securityname ,'', sum(bal) as Total from tablename
group by 1,2,3 --GrandTotal
)

Securityname	Quantity	Total
#Group1 :
Item1	50.0
Item2	30.0
Group1- Subtotal		80
#Group2 :
Item1	10.0
Group2- Subtotal		10
Grand Total		90
