Sql Cleanse to one row - sql

Question

I am struggling with the solution to a query and any help would be greatly appreciated, I end up tying myself In knots with temptables and I'm sure there must be an easier way.
I have a database currently producing the below results - this is as it comes with no joins or production prior.
Acc No | prod No | Product Type | product Cost
12345678 1 Red Toy £100
12345678 2 Blue Toy £150
12345678 3 White Toy £300
12398654 1 White Toy £300
12398765 1 Red Toy £100
I only want one row per account number but don't want to lose the information. I would also like some sums. The below should hopefully show what I mean though there would be more columns:
Acc No | Prod total | cost | Prod1type | Prod1cost |prod2typ
12345678 3 £550 Red Toy £100 BlueToy
12398654 1 £300 White Toy £300 Null
I hope this explains it. I'm aware I would end up with many more columns but it would make my life so much easier.
Any help would be hugely appreciated,
Thanks in advance,

Answer 1

With out considering adding ProdType you could use this query.
Assume also there is only 1 product per line in table.
select acc_no, count(*) as prod_total, sum(cost) as total_cost
from table
group by acc_no
order by acc_no asc
to get all ProdType for a coresponding acc_no you could use
select distinct prodtype
from table
where acc_no='exact_number'

Answer 2

You can use multiple case statements to get your expected output.
Create sample data:
select 12345678 as Accno , 1 as prodno, 'Red Toy' as Producttype , 100 as Cost into #temp union all
select 12345678 as Accno , 2 as prodno, 'Blue Toy' as Producttype , 150 as Cost union all
select 12345678 as Accno , 3 as prodno, 'White Toy' as Producttype , 300 as Cost union all
select 12398654 as Accno , 1 as prodno, 'White Toy' as Producttype , 300 as Cost union all
select 12398765 as Accno , 1 as prodno, 'Red Toy' as Producttype , 100 as Cost
Query:
select accno, count(distinct prodno) Prodtotal, sum(cost) totalCost, max(case when prodno = 1 then Producttype end ) Product1type,
sum (case when prodno = 1 then cost end) Product1cost, max(case when prodno = 2 then Producttype end ) Product2type,
sum (case when prodno = 2 then cost end) Product2cost,max(case when prodno = 3 then Producttype end ) Product3type,
sum (case when prodno = 3 then cost end) Product3cost from #temp
group by accno
Output:
Formatting might be little bit different, but I assume this is your expected output.
accno Prodtotal totalCost Product1type Product1cost Product2type Product2cost Product3type Product3cost
12345678 3 550 Red Toy 100 Blue Toy 150 White Toy 300
12398654 1 300 White Toy 300 NULL NULL NULL NULL
12398765 1 100 Red Toy 100 NULL NULL NULL NULL
