需要帮助以实现所需的输出

Question

我需要将某些表格中的数据转换为特定格式。 您能帮我实现所需的输出吗？

以下链接包含一个 Excel 附件，其中包含以下信息： Google Drive Link

1. Tab : Input-Output --> 包含源表和目标表的结构
2. 选项卡：创建脚本 --> 创建脚本以创建所有表
3. 选项卡：插入脚本 --> 插入脚本以将数据插入到源表中

我尝试过的编辑（代码）：

TYPE subline_col_c_rectype IS RECORD
   (
ID_C    VARCHAR(75), 
Col_C1  VARCHAR(75), 
Col_C2 VARCHAR(75)

   );

   TYPE subline_col_c_tabtype IS TABLE OF subline_col_c_rectype
      INDEX BY BINARY_INTEGER;   


   TYPE line_rectype IS RECORD
   (

   ID_A VARCHAR(75), 
   Col_A1    VARCHAR(75), 
   Col_A2    VARCHAR(75), 
   Col_A3    VARCHAR(75), 
   Col_A4    VARCHAR(75), 
   Col_A5    VARCHAR(75), 
   ID_B  VARCHAR(75), 
   Col_B1    VARCHAR(75), 
   Col_B2    VARCHAR(75), 
   Col_B3    VARCHAR(75), 
   Col_B4    VARCHAR(75), 
    Col_B5 VARCHAR(75), 
    Col_C    subline_col_c_tabtype,
        Col_D    subline_col_c_tabtype
);

   TYPE line_tabtype IS TABLE OF line_rectype
      INDEX BY BINARY_INTEGER;

能够将记录存储在关联数组 line_tabtype 中，但不确定如何展开子记录并将其存储在目标表中。

ORDER BY NVL (ID_A, ID_Y), NVL (rn_a, rn_y)

insert into poc_Target_C 
select id_A, col_A1, col_A2, col_A3, col_A4, col_A5, isnull(id_B,'') as id_b, isnull(col_B1,'') as col_B1, isnull(col_B2,'') as col_B2, 
isnull(col_B3,'') as col_B3, isnull(col_B4,'') as col_B4, isnull(col_B5,'') as col_B5, isnull(id_C,'') as id_C, isnull(col_C1,'') as col_C1, 
isnull(col_C2,'') as col_C2, isnull(id_D,'') as id_D, isnull(col_D1,'') as col_D1, isnull(col_D2,'') as col_D2 
from poc_source_A left outer join poc_source_B on poc_source_A.id_A=poc_source_B.id_B left outer join 
(poc_source_C left outer join poc_source_D on poc_source_C.id_C=poc_source_D.id_d 
and poc_source_C.col_C1=('C'+substring(poc_source_D.col_D1,2,len(poc_source_D.col_D1)))) on poc_source_A.id_A=poc_source_C.id_C;

这可能会帮助您以所需格式插入数据。
