sql - Using entity framework and MSSQL AVG() function -


i have line of code (using mssql):

double avg = db.mytable.where(x => x.recorddate < today).select(z => z.value).average();

i wonder if translated sql avg() function or average() run on client side ?

this table contains 50,000 records per day , prefer let database calculate average , pass single value.

and, how can see sql query sent database ?

if don't enumerate queryable, yes, average done on db side.

you can simplify code. select not needed, there's overload average taking expression<func<t, double>> (or decimal, int...) parameter.

double avg = db.mytable.where(x => x.recorddate < today).average(z => z.value);

and quite many ways see sql generated, can google sql generated linq, or take here, example
