case when(c.salutation = 'dhr.' or c.salutation = 'dhr.')          'meneer'+' '+isnull(c.middlename+' ','')+c.lastname     when(c.salutation = 'mw.' or c.salutation = 'mw.')          'mevrouw'+' '+isnull(c.middlename+' ','')+c.lastname     else 'meneer/mevrouw '+isnull(c.middlename+' ','')+isnull(c.lastname,'') end 'k5'
