How to delete versions of (permanently) deleted documents

[pibou_Bouvret]

All is in the title.

Through the UI, the nxql query "select * from Document where ecm:uuid = XXX" retrieves the document version, but i can t delete or access it ( "Failed to get head document for" ).

What nxql query would fit my needs ?

This cannot be done by a non-superuser.

Also, NXQL is only for SELECT, there is no DELETE in NXQL.
