Question

The code, with two Linq-to-SQL queries, that I am trying to optimize is below:

        var maxAInstant =             (                 from a in db.As                 select a.Instant             )             .Max();         var maxBInstant =             (                 from b in db.Bs                 select b.instant             )             .Max();         var interval = maxAInstant - maxBInstant;         bool result = interval > new TimeSpan(0, 0, 1); 

Can I obtain the result with a single Linq-to-SQL query?

Answer 1

Try this:

bool result = (db.As.Max(a => a.Instant) - db.Bs.Max(b => b.instant)) > new TimeSpan(0,0,1);
