Answer 1

joinは必要ありません。 caseはselectに行く：あなたは条件が機能する場合の後、列名が必要

SELECT . . ., 
     CASE ?? 
      WHEN 'Family Law' then 'FL' 
      WHEN 'Workers Comp' then 'WC' 
      WHEN 'Criminal' then 'CR' 
      WHEN 'Corporate Business' then 'CB' 
      WHEN 'Personal Injury' then 'PI' 
      WHEN 'Litigation' then 'LI' 
      WHEN 'Estate Matters' then 'EM' 
      WHEN 'Miscellaneous' then 'MI' 
      WHEN 'Appeals' then 'AP' 
      WHEN 'Real Estate' then 'RE' 
     END as areaoflaw 
from matters 
order by Clientid;
