Question

我有传入表交易

表名：WA_II_TBL_TR_EQUIPMENT

TRANSACTION_EQUIPMENTID | DESCRIPTION | SUPPLIERID_FK | PART_NO | QUANTITY
TE201708000002          | fg          | 62551         | GSDFGSG | 2
TE201709000003          | fg          | 62551         | PA000535| 7
TE201709000002          | fg          | 62551         | GSDFGSG | 9
TE201708000004          | fg          | 62551         | GSDFGSG | 10
TE201708000003          | fg          | 62551         | GSDFGSG | 2
TE201709000001          | Test        | 48544         | Test    | 8

在上表中我们可以看到3 PART_NO

现在我需要先获得TRANSACTION_EQUIPMENTID并根据SUM(QUANTITY)分组以获得PART_NO：

TRANSACTION_EQUIPMENTID | PART_NO | QUANTITY
TE201708000002          | GSDFGSG | 23
TE201709000003          | PA000535| 7
TE201709000001          | Test    | 8

查询：

SELECT
   MIN(TRANSACTION_EQUIPMENTID),
   PART_NO,
   SUM(T.QUANTITY) AS TOTAL
FROM
   WA_II_TBL_TR_EQUIPMENT T
WHERE
   T.SUPPLIERID_FK = '62551'
GROUP BY
   T.PART_NO

正如您现在所见，我可以先获得TRANSACTION_EQUIPMENTID，即TE201708000002

现在我有外出表交易

表名：WA_II_TBL_TR_OUT_EQUIPMENT

TRANSACTION_OUT_EQUIPMENTID | TRANSACTION_EQUIPMENTID_FK | QUANTITY <--QUANTITY OUT
TOE201709000001             | TE201708000002             | 3

假设我有PART_NO = GSDFGSG的外向交易，数量输出= 3.（已插入第一个ID：TE201708000002。）

现在我希望在查询时根据表TRANSACTION_EQUIPMENTID在表WA_II_TBL_TR_EQUIPMENT上获得第一个WA_II_TBL_TR_OUT_EQUIPMENT。

TRANSACTION_EQUIPMENTID TE201708000002已经消耗了数量输出3.现在它应该是下一个TRANSACTION_EQUIPMENTID TE201708000003，因为它仍然有这些ID的数量休息1。

如何根据消耗的TRANSACTION_EQUIPMENTID获得第一个WA_II_TBL_TR_OUT_EQUIPMENT？

在这种情况下应该是这样的：

TRANSACTION_EQUIPMENTID | PART_NO | QUANTITY
TE201708000003          | GSDFGSG | 20 (Rest Quantity, before 23)
TE201709000003          | PA000535| 7

以下新案例

在表格WA_II_TBL_TR_OUT_EQUIPMENT上，我有以下数据：

TRANSACTION_EQUIPMENTID_FK | QUANTITY
TE201708000002             | 3
TE201708000003             | 1

当我查询代码时

ID             | PART_NO | SEI_NO   | REST
TE201708000003 | GSDFGSG | SDGDFGSD | 1 <-- it should be 0

查询：

select id, part_no, sei_no, sq2 - nvl(oq2, 0) rest
from (
select tr.*, row_number() over (partition by part_no, sei_no order by id) rnk
  from (select i.transaction_equipmentid id, part_no, sei_no, i.quantity iq, 
               sum(i.quantity) over (partition by part_no,sei_no
                                         order by i.transaction_equipmentid) sq1,
               sum(i.quantity) over (partition by part_no, sei_no) sq2,
               o.quantity oq1,
               max(o.quantity) over (partition by part_no, sei_no) oq2
               from wa_ii_tbl_tr_equipment  i 
          left join wa_ii_tbl_tr_out_equipment o 
            on o.transaction_equipmentid_fk = i.transaction_equipmentid
          where i.supplierid_fk = 62551 ) tr
  where sq1 >= oq2 or oq2 is null )
 where rnk = 1;

Answer 1

select id, part_no, sq2-oq2 rest
  from (
    select tr.*, row_number() over (partition by part_no order by id) rnk
      from (select i.transaction_equipmentid id, part_no, i.quantity iq, 
                   sum(i.quantity) over (partition by part_no 
                                             order by i.transaction_equipmentid) sq1,
                   sum(i.quantity) over (partition by part_no) sq2,
                   o.quantity oq1,
                   max(o.quantity) over (partition by part_no) oq2
                   from wa_ii_tbl_tr_equipment  i 
              left join wa_ii_tbl_tr_out_equipment o 
                on o.transaction_equipmentid_fk = i.transaction_equipmentid
              where i.supplierid_fk = 62551 ) tr
      where sq1 >= oq2 or oq2 is null )
  where rnk = 1

我加入输入和输出，然后使用分析函数sum()和max()我准备所有需要的信息，最重要的是累积和。您可以看到它单独运行最内部查询，别名为tr。

下一步只是添加row_number()来查找输入大于输出的第一行，并显示此行和剩余的差异。

此条件：还需要or oq2 is null来显示其他部分（此处为PA000535）。

请阅读有关分析功能的内容，网上有很多教程。

测试数据：

create table WA_II_TBL_TR_EQUIPMENT(
    TRANSACTION_EQUIPMENTID varchar2(15), DESCRIPTION varchar2(10), 
    SUPPLIERID_FK number(6), PART_NO varchar2(10), QUANTITY number(6));

insert into WA_II_TBL_TR_EQUIPMENT values ('TE201708000002', 'fg',   62551, 'GSDFGSG',  2);
insert into WA_II_TBL_TR_EQUIPMENT values ('TE201709000003', 'fg',   62551, 'PA000535', 7);
insert into WA_II_TBL_TR_EQUIPMENT values ('TE201709000002', 'fg',   62551, 'GSDFGSG',  9);
insert into WA_II_TBL_TR_EQUIPMENT values ('TE201708000004', 'fg',   62551, 'GSDFGSG', 10);
insert into WA_II_TBL_TR_EQUIPMENT values ('TE201708000003', 'fg',   62551, 'GSDFGSG',  2);
insert into WA_II_TBL_TR_EQUIPMENT values ('TE201709000001', 'Test', 48544, 'Test',     8);

create table WA_II_TBL_TR_OUT_EQUIPMENT(
    TRANSACTION_OUT_EQUIPMENTID varchar2(15), 
    TRANSACTION_EQUIPMENTID_FK varchar2(15), 
    QUANTITY number(6));

insert into WA_II_TBL_TR_OUT_EQUIPMENT values('TOE201709000001', 'TE201708000002', 3);

输出：

ID              PART_NO          REST
--------------- ---------- ----------
TE201708000003  GSDFGSG            20
TE201709000003  PA000535
