Add to the View definition

There are two things you can do to add to the View definition, external to the Database View dialog:

·To provide a name for the View, select the element on the diagram, press F2 and type the new name
·Either:
·Create a Dependency connector from the View to each Table on which the View depends, or
·Open the Tagged Values window (Ctrl+Shift+6), add the tag parents and type in the Table names (separated by commas) as the tag value

 Double-click on the View to display the Properties dialog; the Tables are now listed in the Dependencies field, in a vertical list

·The View definition and certain other parameters are held as Tagged Values; the View definition is held in the viewdef memo Tagged Value
 
You can select and view the viewdef Tagged Value in the Tagged Values window, and include it in document reports by inserting the valueOf(viewdef) field in the Package::Package Element or Package::Element sections
