> FROM hierarchy _nxhier
> LEFT JOIN proxies ON proxies.id = _nxhier.id

> proxies.targetid)
> LEFT JOIN dublincore ON hierarchy.id = dublincore.id
> LEFT JOIN misc ON hierarchy.id = misc.id
> WHERE
> hierarchy.primarytype IN ('Workspace')
> AND (misc.lifecyclestate <> 'deleted')
> AND (NOT (NX_IN_TREE(_nxhier.id, '7bdcedfe-3b42-4676-a823-c818396bef58')))
> AND NX_ACCESS_ALLOWED(_nxhier.id, '{members,user5,Everyone}',
