Question

What is the correct eSQL syntax to compare dates?

The equivalent LINQ-to-Entities expression would look something like this:

var lastYearsShipments = from p in MyDataServiceContext.Products                          where p.ShipDate.Value.Year == DateTime.Now.Year - 1                          select p; 

Answer 1

They say it’s acceptable to answer your own question, so here goes …

var predicate = string.Format(     'Year(it.ShipDate) == Year(cast('{0}' as System.DateTime)) -1',     System.DateTime.Now);  var lastYearsShipments =      myQuery.Products.Where(predicate); // myQuery is type ObjectQuery<T>
