Progress DB的复合案例

Question

我试图在OpenEdge SQL-92查询中执行一个case语句，该查询可以有两列定义输出。

SELECT 
  "PERSON"."First",
  "PERSON"."Last",
  "PERSON"."EmpCode" as EmployeeCode,
  CASE "PERSON"."Building"
     WHEN '111' then 'HQ'
     WHEN '222' then 'OPS'
     WHEN '111' AND "PERSON"."EmpCode" = 'CCLASS' then 'MGMT'
  END as Location
FROM ....

复合大小写在运行查询时抛出语法错误。我知道我可以在MSSQL中做到这一点......我想我也可以用于OpenEdge吗？

有关如何使用OpenEdge SQL实现这一点的想法吗？

根据没有名字的马提议：

  CASE 
     WHEN "PERSON"."Building" = '111' then 'HQ'
     WHEN "PERSON"."Building" = '222' then 'OPS'
     WHEN "PERSON"."Building" = '111' AND "PERSON"."EmpCode" = 'CCLASS' then 'MGMT'
  END as Location
