Linq to XML query to SQL - sql

Question

UPDATE:
I've turned my xml into a query table in coldfusion, so this may help to solve this.
So my data is:
[id] | [code] | [desc] | [supplier] | [name] | [price]
------------------------------------------------------
1 | ABCDEF | "Tst0" | "XYZ" | "Test" | 123.00
2 | ABCDXY | "Tst1" | "XYZ" | "Test" | 130.00
3 | DCBAZY | "Tst2" | "XYZ" | "Tst2" | 150.00
Now what I need is what the linq to xml query outputs below. Output should be something like (i'll write it in JSON so it's easier for me to type) this:
[{
"code": "ABCD",
"name": "Test",
"products":
{
"id": 1,
"code": "ABCDEF",
"desc": "Tst0",
"price": 123.00
},
{
"id": 2,
"code": "ABCDXY",
"desc": "Tst1",
"price": 130.00
}
},
{
"code": "DCBA",
"name": "Tst2",
"products":
{
"id": 3,
"code": "DCBAZY",
"desc": "Tst2",
"price": 150.00
}
}]
As you can see, Group by the first 4 characters of 'CODE' and 'Supplier' code.
Thanks
How would i convert the following LINQ to XML query to SQL?
from q in query
group q by new { Code = q.code.Substring(0, 4), Supplier = q.supplier } into g
select new
{
code = g.Key.Code,
fullcode = g.FirstOrDefault().code,
supplier = g.Key.Supplier,
name = g.FirstOrDefault().name,
products = g.Select(x => new Product { id = x.id, c = x.code, desc = string.IsNullOrEmpty(x.desc) ? "Description" : x.desc, price = x.price })
}
Best i could come up with:
SELECT c, supplier, n
FROM products
GROUP BY C, supplier, n
Not sure how to get the subquery in there or get the substring of code.
ps: this is for coldfusion, so I guess their version of sql might be different to ms sql..

The easiest way is to attache a profiler to you database and see what query is generate by the linq-to-SQL engine.
