Hi Paul,
This seems to do the trick for me:

Hi Katrin -- and for me :=) Found one more "floating RLIN" in the 600$a fields and also ran it for all other 6xx without further errors showing up.

Many thanks for a great start to my day.

Paul


SELECT
  biblionumber
FROM
  biblioitems
WHERE
  ExtractValue(marcxml,'//datafield[@tag="600"]/subfield[@code="a"]') = ""
AND ExtractValue(marcxml,'count(//datafield[@tag="600"]/subfield[@code="a"])') = 1

Found the solution here: http://dev.mysql.com/doc/refman/5.1/en/xml-functions.html#function_extractvalue
