You can also set the Set Range property to retrieve a subset of records from a table by filtering on a range of values of a named index from the table.The following example fetches records from the Products table fetching only those records with a Product ID between 30 and 40.

Sql Server Ce to your Windows® Forms application enables developers for desktop and mobile device applications to take advantage of the improved performance.With a Sql Ce Result Set object, you are working directly against the data that is stored in the database, and you avoid the overhead of reading out of the database, only to cache it in memory in a Data Set object before working with it in your application.The Sql Ce Result Set object makes much more sense on memory-constrained devices.
