hScheduleMaterializedView (Type of variable)

In french: hPlanificationVueMatérialisée

The hScheduleMaterializedView type is used to manage a task for re-calculating the data of a scheduled materialized view on a HFSQL server by programming.
The characteristics of this task can be defined and modified by several WLanguage properties.

Remarks:

For more details on materialized views, see Materialized view.
See Declaring a variable for more details on the declaration of this type of variable and the use of WLanguage properties.

Example

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

// 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"
refreshView.View[1] = "MyDatabase/MyView"

HAddScheduling(cnt, refreshView)
