Does ADO.NET Entity Data Model Framework take advantage of indexed columns at the time of search over a table?

Suppose you have a table "Person" with an indexed column "Age"

Is the code below faster than itself if no indexed columns exists in table "Person"?

var query = from p in context.People
            where p.Age == 20
            select p;

Hello Arpoarpo,

The where clause part of the code you gave is integrated into the SQL that gets sent to the DBMS by the "Entity Framwork". So yes, if there is an index on column "Age" it should be faster in returning data than
when the column is not indexed. If this is measureable depends on the amount of data in your table.

I hope that answers your question. If you have any doubt check back with me.

Cheers

Manfred
