Question

I have this SQL query that is just impossible to get going in LINQ.

select * from attribute_value t0
where t0.attribute_value_id in
(
    select t1.attribute_value_id from product_attribute_value t1
    where t1.product_attribute_id in
    (
        select t2.product_attribute_id from product_attribute t2
        where t2.product_id in
        (
            select product_id from product p, manufacturer m
            where p.manufacturer_id = m.manufacturer_id
            and m.name = 'manufacturer name'
        )
        and pa.attribute_id = 1207
    )
)

The where clause also has to be done dynamically later on in the code.

Answer 1

Try to use Linqer. I remember writing some really convoluted things with it.

On a side note, your query isn’t all that complex, you’re just going from product to its attribute values. Just make a lot of joins on keys and you’re done.
