Viewing the Schema of a Derived View¶
To view the schema of a view, double-click it in the Server Explorer. In addition to the options available for base views (see section Creating Derived Views), we also have:
Tree View: see section Tree View
Data Lineage: see section Data Lineage
Click Edit to open the “Edit view” dialog. The Tool will open the dialog that corresponds to the operation used to create the view (i.e. join, union, etc.). In this dialog, you can do the following:
Rename the view.
Rename the view’s attributes.
Modify its specific parameters. For example, for join views you can change the join conditions, projected fields, etc.
Alternatively, you can replace the view with another one with the same name (see section Editing / Replacing a View for more details about edition/replacement of views).
See Edit the VQL of a Derived View for details about manually editing the VQL statement that creates the view.
