                .Where(p => object.Equals(p.VCU_VEH_ID, null));

it is creating the below query.

{SELECT
NULL AS "C1",
NULL AS "C2",
NULL AS "C3",
NULL AS "C4",
NULL AS "C5",
NULL AS "C6",
NULL AS "C7",
NULL AS "C8"

Shouldn't be: Where(p => p.VCU_VEH_ID==null)?

Solution 1

It looks like it has decided your query can never return anything so it is creating a query that simply returns an empty row. Probably due to your object.Equals statement. Google "linq select where null" and you'll find the correct syntax for selecting where something is null.
