OCLOperators ExecutePS

From MDrivenWiki

selfVM.ExecutePS() is enabled to use the power and speed of the database to find a subset of objects of a certain type in a ViewModel.

In the example below, ExecutePS is used to look up License objects with PS (avoiding traversing all existing in memory).

The PS-evaluated expression (translated to SQL and executed in DB) is defined in a ViewModelColumn of its own that is not referenced by any UI.

ExecutePS will look for MaxFetch taggedvalue on the root level column and limit returned values.
