Am I misunderstanding LINQ to SQL .AsEnumerable()?

Question

Consider this code:

var query = db.Table
              .Where(t => SomeCondition(t))
              .AsEnumerable();

int recordCount = query.Count();
int          


        

Answer 1

Yes. All that AsEnumerable will do is cause the Count, Sum, and Average functions to be executed client-side (in other words, it will bring back the entire result set to the client, then the client will perform those aggregates instead of creating COUNT() SUM() and AVG() statements in SQL).
