// Refresh the materialized views every Saturday at 23:00
refreshView is hScheduleMaterializedView
refreshView.Description = "View data recalculation"

// Characteristics of the scheduling
refreshView.Scheduling.Month = "*"
refreshView.Scheduling.DayOfWeek = "Saturday"
refreshView.Scheduling.Hour = "23"
refreshView.Scheduling.Minute = "0"

// Add the materialized view to refresh

// Syntax 1:
// Refreshes all the materialized views of "MyDatabase"
refreshView.View[1] = "MyDatabase"

// Syntax 2:
// Refreshes "MyView" of "MyDatabase"
