obiee如何合并两个表？

Question

我的物理层有两个表（由于某种原因）虽然我知道最好是两个联合两个表。表 A 和表 B 具有相同的结构。我的目标是实现一个类似的 sql：

select F1，F2 
     from (select *
           from tableA
           union
           select *
           from tableB)
tableMix

只需合并两个因子表...我如何在管理工具中做到这一点？

现在是这样的 nqquery

WITH SAWITH0 AS
    ((select T3580.AMOUNT as c1, T30887.YEAR_DESC as c2, T30887.YEAR_WID as c3
      from DW_DAY_D T30887 /* A_Dim_DW_TQ_DAY_D */, DW_TQ_PRODUCT_F T3580 /*                    A_Fact_DW_TQ_PRODUCT_F */
      where (T3580.DAY_ID = T30887.DAY_WID)
      union all
      select T120596.AMOUNT   as c1,
      T30887.YEAR_DESC as c2,
      T30887.YEAR_WID  as c3
      from DW_DAY_D T30887 /* A_Dim_DW_TQ_DAY_D */, DW_MHG_PRODUCT_F T120596 /*      A_Fact_DW_MHG_PRODUCT_F */
      where (T30887.DAY_WID = T120596.DAY_ID))),
      SAWITH1 AS
     (select distinct D3.c1 as c1, D3.c2 as c2, D3.c3 as c3 from SAWITH0 D3)
     select distinct 0 as c1, D2.c2 as c2, D2.c1 as c3, D2.c3 as c4
     from SAWITH1 D2
     order by c4, c3

但我无法将聚合规则设置为“金额”上的“总和”。

选项 1： 您可以在物理层中创建一个不透明的视图。该视图将是您在帖子中提到的查询。

选项 2： 在 BMM 层中，创建一个逻辑表（tableMix），其中包含两个逻辑表源（tableA 和 tableB）。
