Answer 1

您不需要join。 case位于select：

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;

请注意，在条件工作的情况下，您需要一个列名。这就是??的用途。
