Hi Robert,
you are right it works with CONCAT, but, isn't CONCAT inconsistent
here?
This seems to work as desired:
CONCAT( [Vorname], IFNULL( CONCAT( ' & ', [Partnervorname] ), '' ), '
', [Nachname] )
But shouldn't the CONCAT( ' & ', [Partnervorname] ), '' ) actually
return a NULL due to the '' (i.e. not a space, zero length)?
Cheers
Harvey
