Question

这是我正在使用的表格的ddl。

CREATE TABLE "BISAMPLE"."SUMLEDGER" 
   (    "FUND" VARCHAR2(6 BYTE), 
    "ORG" VARCHAR2(6 BYTE), 
    "ACCT" VARCHAR2(6 BYTE), 
    "PROG" VARCHAR2(6 BYTE), 
    "YEAR" NUMBER, 
    "S01_BUDGET" NUMBER, 
    "S01_BUDGET_ADJ" NUMBER, 
    "S01_YTD_ACTV" NUMBER, 
    "S01_ENCUMB" NUMBER, 
    "S02_BUDGET" NUMBER, 
    "S02_BUDGET_ADJ" NUMBER, 
    "S02_YTD_ACTV" NUMBER, 
    "S02_ENCUMB" NUMBER
   )

以下是示例数据的插入。

REM INSERTING into SUMLEDGER
SET DEFINE OFF;
Insert into SUMLEDGER (FUND,ORG,ACCT,PROG,YEAR,S01_BUDGET,S01_BUDGET_ADJ,S01_YTD_ACTV,S01_ENCUMB,S02_BUDGET,S02_BUDGET_ADJ,S02_YTD_ACTV,S02_ENCUMB) values ('100001','3999','3220','06',6,20,30,15,15,10,20,10,40);
Insert into SUMLEDGER (FUND,ORG,ACCT,PROG,YEAR,S01_BUDGET,S01_BUDGET_ADJ,S01_YTD_ACTV,S01_ENCUMB,S02_BUDGET,S02_BUDGET_ADJ,S02_YTD_ACTV,S02_ENCUMB) values ('100001','3999','3220','06',7,20,30,15,15,10,20,30,40);
Insert into SUMLEDGER (FUND,ORG,ACCT,PROG,YEAR,S01_BUDGET,S01_BUDGET_ADJ,S01_YTD_ACTV,S01_ENCUMB,S02_BUDGET,S02_BUDGET_ADJ,S02_YTD_ACTV,S02_ENCUMB) values ('100001','3999','3460','06',6,25,30,20,20,20,20,30,40);
Insert into SUMLEDGER (FUND,ORG,ACCT,PROG,YEAR,S01_BUDGET,S01_BUDGET_ADJ,S01_YTD_ACTV,S01_ENCUMB,S02_BUDGET,S02_BUDGET_ADJ,S02_YTD_ACTV,S02_ENCUMB) values ('100001','3999','3220','06',8,20,35,25,30,30,22,15,30);

这是将在此查询中使用的第二个表。

CREATE TABLE "BISAMPLE"."FUNDING" 
   (    "FUNDING_START_DATE" DATE, 
    "FUNDING_NUMBER" VARCHAR2(6 BYTE)
   )

这是表格插页。

REM INSERTING into FUNDING
SET DEFINE OFF;
Insert into FUNDING (FUNDING_START_DATE,FUNDING_NUMBER) values (to_date('21-JAN-2017 03:47:42','DD-MON-RRRR HH24:MI:SS'),'100001');

我正在尝试使用unpivot函数将列转换为行。但是我现在很不成功。但是，我可以使用以下查询来完成相同的输出。

有人可以帮我用unpivot函数重写吗？使用上述方法需要我至少联合14次，因为有14个可能的句点/列这个表的一个快速抬头包含大约98列我已经将这里的示例简化为少数几列以更好地解释而不是压倒。< / p>

这是我想要复制的输出

Answer 1

预期结果中的speriod不正确。你最后四行应该有02个。

试试这个：

select
  s.fund,
  s.org,
  s.acct,
  s.prog,
  s.year,
  s.budget + s.budget_adj budg,
  s.year_to_date,
  s.encumbrance,
  s.s_period,
  to_number(to_char(add_months(f.funding_start_date, s_period - 1), 'MM')) s_month,
  decode(to_char(f.funding_start_date,'MM'),'12',year + s_period - 1, year) s_year
from (
  select *
  from sumledger
  unpivot ( 
    (budget, budget_adj, year_to_date, encumbrance) 
    for s_period in (
      (s01_budget,s01_budget_adj,s01_ytd_actv,s01_encumb) as 1,
      (s02_budget,s02_budget_adj,s02_ytd_actv,s02_encumb) as 2)
  )
) s inner join funding f on s.fund = f.funding_number;
