SQL split totals - sql

Question

Currently I have the following result in SQL:
qty
description
volume
weight
4
Flowers
3,4
4
This is in an XML format. So what I want to do, and I think I need to user "FOR XML PATH" in a certain way, but I am not sure how to achieve the following result:
qty
description
volume
weight
1
Flowers
0,85
1
1
Flowers
0,85
1
1
Flowers
0,85
1
1
Flowers
0,85
1
So I need to divide the XML path based on the total qty (4). For each (4) products, I need to create a new row. Then divide the volume and the weight (/qty).
Can anyone help me to push me into the right direction?
Edit:
The first result, qty of 4, is a result in a temp table.
I extract the data from the temp table into XML format. Here is a snippet
(SELECT "qty" = value('(#col24)[1]', 'varchar(50)'), "weight" = value('(#col28)[1]', 'varchar(50)'), "volume" = value('(#col26)[1]', 'decimal(16,2)') FOR XML PATH('product'), ROOT('products'), TYPE)
The qty, weight and volume represents the totals.
This is what I want to devide to create a "product" for each "qty".

You can use a recursive CTE to split the rows (you might need to up the recursion limit if your quantity can be higher than 100).
declare #Test table (qty int, [description] varchar(64), volume decimal(9,2), [weight] decimal(9,2))
insert into #Test (qty, [description], volume, [weight]) values (4, 'Flowers', 3.4, 4);
with cte as (
select qty, [description], volume, [weight], 1 as rn
from #Test
union all
select qty, [description], volume, [weight], rn + 1
from cte
where rn < qty
)
select 1 qty, [description], cast(volume / qty as decimal(9,2)) volume, cast([weight] / qty as decimal(9,2)) [weight]
from cte
for xml path('product'), root('products'), type;
-- option (maxrecursion 200); -- If you need to increase it above the default of 100
Note: If you setup the DDL+DML, as I shown, in your questions you make it much easier for people to reply.

One way is by recursive CTE:
WITH cte AS (
SELECT *, qty AS cc, 1 org FROM #sale
UNION ALL
SELECT cte.qty /qty
, cte.description
, cte.volume /qty
, cte.weight /qty
, cte.cc - 1 AS cc
, 0 org
FROM cte
WHERE cc > 1
)
SELECT * FROM cte
where org = 0
FOR XML path
However if you have a tally table it will faster and simpler:
SELECT qty /qty
, description
, volume /qty
, weight /qty
FROM table
JOIN numbertables < -- number tables from 1 to max
on numbertables.values < qty
FOR XML path
