Question

Querying a Nested Set Model table, here’s the SQL… how can this be written in LINQ?

SELECT parent.name
FROM nested_category AS node, nested_category AS parent
WHERE node.lft BETWEEN parent.lft AND parent.rgt
AND node.name = 'FLASH'
ORDER BY parent.lft;

particularly, the FROM part… never tried to do anything like that in LINQ.

Answer 1

Perhaps something like:

var query = from node in nested_category
            from parentNode in nested_category
            where node.lft >= parentNode.lft && node.rgt <= parentNode.rgt
                 && node.name == "FLASH"
            orderby parent.left
            select parent.name;
