View source for HowTo:Use a Query in a View

A [[QUERY|Query]] object can be shown within a [[VIEW|View]] hierarchy similar to any other object, once the query is placed either as root object of the view or a child of another object shown in the view.
{{Hint|Be aware that a corresponding [[VIEWITEMS|View Item]] is necessary for a query as well.}}

=== Place query among root objects ===
# Navigate to the [[MetaClass]] [[VIEW]] in the ''[[Class Browser]]''.<br/>[[File:UI_Use_Query_View_01.PNG|220 px|border|alt=Unit|Unit]]
# To see now the entire structure in the ''View Test Environment'', locate an existing ''View'', nor the required Root objects must be added to view with the ''Relation Editor''.<br/>[[File:UI_Use_Query_View_02.PNG|330 px|border|alt=Unit|Unit]]

# Connect a View object to the {{Relation Editor}} 
# The query object needs to be added to the list of root objects, there are two different ways to achieve that:
:*Individual objects can be added directly to the [[SYSREL_VIEWROOT|Root object relation]] of the ''View'' using the [[Relation Editor#Drag & Drop|Relation Editor]].
:*To add multiple query objects, another ''Query'' has to be created and added to the [[SYSREL_VIEWROOTQUERY|Root query relation]] in the ''View''.<br/>[[File:UI_Use_Query_View_02.PNG|330 px|border|alt=Unit|Unit]]
# Save the changes with {{key press|Ctrl|S}} or the save command

{{Attention|Only the objects which are located directly underneath the Infrastructure relation will be part of the infrastructure. Their child objects will NOT be included (automatically).}}
