Class CreateViewConstantAction

  • All Implemented Interfaces:
    ConstantAction
    class CreateViewConstantAction
extends DDLConstantAction
    This class describes actions that are ALWAYS performed for a CREATE VIEW Statement at Execution time. A view is represented as:
    • TableDescriptor with the name of the view and type VIEW_TYPE
    • Set of ColumnDescriptor's for the column names and types
    • ViewDescriptor describing the SQL query that makes up the view.
    Dependencies are created as:
    • ViewDescriptor depends on the Providers that its compiled query depends on.
    • ViewDescriptor depends on the privileges required to execute the view.
    Note there are no dependencies created between the ViewDescriptor, TableDecriptor and the ColumnDescriptor's.
