Thanks Tom

I couldn't figure out how to do the JOIN part of that statement. Using your
instruction all I had left to do was drop the qualification off the SET column
and it worked. :-) Thanks again.

UPDATE tbl_line_item
SET reviewed = TRUE
FROM tbl_item
WHERE tbl_line_item.item_id = tbl_item.id
AND item_type = 'DIR';

Kind Regards,
