                                              throws StandardException

Description copied from class: StatementPermission

Get the PermissionsDescriptor for the passed authorization id for this object. This method gets called during the execution phase of create view/constraint/trigger. The return value of this method is saved in dependency system to keep track of views/constraints/triggers dependencies on required permissions. This happens in execution phase after it has been established that passed authorization id has all the permissions it needs to create that view/constraint/trigger. Which means that we can only get to writing into dependency system once all the required privileges are confirmed.

Specified by:

getPermissionDescriptor in class StatementPermission

Parameters:

authid - AuthorizationId

dd - DataDictionary

Returns:

PermissionsDescriptor The PermissionsDescriptor for the passed authorization id on this object

Throws:

StandardException
