t.cmis:contentStreamMimeType, t.cmis:contentStreamLength, t.cmis:objectId, t.cmis:objectTypeId

Remove the order by clause and the select works.

SELECT t.cmis:name, t.cmis:createdBy, t.cmis:creationDate, t.cmis:lastModifiedBy, t.cmis:lastModificationDate,
t.cmis:contentStreamMimeType, t.cmis:contentStreamLength, t.cmis:objectId, t.cmis:objectTypeId
FROM cmis:document t WHERE ((t.cmis:name LIKE 'My%'))
