SortedEntityClass [class,prop]
represents an entity class derived from class by sorting according to the values of the property prop.
SortedEntityClass [class,prop"order"]
sorts according to prop in the order specified.
SortedEntityClass [class,{prop1,prop2,…}]
breaks ties by successively using the values of the property specifications propi.
SortedEntityClass [class,sortspec,n]
represents the first n entities of class when sorted by sortspec.
SortedEntityClass [class,sortspec,{m,n}]
represents the entities m through n of class when sorted by sortspec.

SortedEntityClass [class,prop]

SortedEntityClass [class,sortspec,n]
represents the first n entities of class when sorted by sortspec.
SortedEntityClass [class,sortspec,{m,n}]
represents the entities m through n of class when sorted by sortspec.
Details
- In SortedEntityClass [class,sortspec,n], when class contains fewer than n entities, all entities are used.
- In SortedEntityClass [class,{prop1,prop2,…}], propi can be given as EntityProperty , EntityFunction or string.
- SortedEntityClass [class,prop,-n] is effectively equivalent to SortedEntityClass [class,prop->"Descending",n].

Use SortedEntityClass to sort a class of entities:
Change the direction of the order:
Take only the first 10 entities:
Sort by multiple criteria:
When used with relational-database-backed entities, SortedEntityClass is equivalent to an ORDER BY statement:

The same class can be more simply expressed by using SortedEntityClass with three arguments:
