Question

我可以在一行中显示以下结果吗？

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

结果是否都出现在同一行？

Answer 1

1.分离所有差异列

2.使用所有差异列制作子查询，然后转换为数据透视表

3.再次使用主查询加入

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
)
