Oracle SQL：在一行上返回结果

Question

我可以使以下结果显示在一行上吗？

当前，CASE_COMPONENT_PART，CASE_DESCRIPTION和CASE_PROD与TRAY_COMPONENT_PART，TRAY_DESCRIPTION和TRAY_PROD位于不同的行。

结果可以全部显示在同一行吗？

Answer 1

1.分隔所有差异列

2.使所有差异列的子查询然后转换为数据透视

3.再次加入主查询

SELECT CASE_COMPONENT_PART
     , CASE_DESCRIPTION
     ,CASE_PROD

FROM table_a

LEFT JOIN (

    SELECT id [PK_for_join_first_query]
         ,TRAY_COMPONENT_PART
         ,TRAY_DESCRIPTION,TRAY_PROD

    FROM table_b -- Pivot this Query
)
