根据 Oracle 中的百分比计算更新多列 [英] Update multiple columns based on percentage wise calculation in Oracle

问题描述

注意:使用示例数据和输出更新总问题.

NOTE: Updating total question with sample data and output.

我需要通过与另一个表进行比较来更新一些列，并以百分比方式更新列.所以我走了.

I need to update some columns by comparing from another table and update the columns percentage wise. So here I go.

首先，获得CMM批准长度的查询在下面还有我需要的其他列

first of all , the query to get CMM approved length is below with other columns which I need

select CIRCLE,regexp_substr(MP,'[^/]+',1,1)MPNAME,regexp_substr(MP,'[^/]+',1,2)MPCODE,
 SPAN_TYPE,SPAN_LINK_ID,NE_LENGTH AS NE_LEN,
 ROUTE_APPROVED_BY_CMM as CMM_APPROVED_LENGTH from 
 TBL_FIBER_INV_CMP_REPORT_MV
 where CMM_APPROVED_DATE IS NOT NULL OR ROUTE_APPROVED_BY_CMM > 0 OR 
 JOB_PROGRESS_FLAG = 1;

上面查询的输出如下图所示

and the output of above query looks like this below image

现在是第二部分，即百分比的计算

CASE 1:如果上图中 CMM 批准的长度是 70km 并且从 (NE,UG, AR len from NE.MV_SPAN@DB_LINK_NE_VIEWER) 出来的 NE 长度为 100Km 然后划分 (UG=80Km 和 AR=20Km)

CASE 1: If The CMM approved length in above image is 70km and NE length from (NE,UG, AR len from NE.MV_SPAN@DB_LINK_NE_VIEWER)comes out to be 100Km then divide (UG=80Km and AR=20Km)

那么分叉的百分比将是 80% UG_length 和 20% AR_length.因此，针对 CMM 批准的 70 公里公里，TBL_FIBER_INV_SIGN_OFF_SHEET 应将列更新为 UG = 56Km 和 AR = 14Km.分叉应在下表中更新TBL_FIBER_INV_SIGN_OFF_SHEET

Then percentage of bifurcation would be 80% UG_length and 20% AR_length. So, against 70km of CMM approved kilometer, TBL_FIBER_INV_SIGN_OFF_SHEET should update the column as UG = 56Km and AR = 14Km. the bifurcation should be updated in below table TBL_FIBER_INV_SIGN_OFF_SHEET

表示例数据如下所示:-

and the table sample data looks like below:-

CASE 2: 如果CMM 批准长度 和NE 长度 相同.例如:70km(UG = 60 Km 和 AR=10Km)然后在 TBL_FIBER_INV_SIGN_OFF_SHEET 表中应该更新 UG = 60Km and AR = 10Km.

CASE 2: IF CMM approved length and NE length is same. for ex: 70km (UG = 60 Km and AR=10Km) then in TBL_FIBER_INV_SIGN_OFF_SHEET table should update UG = 60Km and AR = 10Km.

以下是两个表的表描述.

Below are the table description of both the tables.

CREATE OR REPLACE PROCEDURE UPD_UG_AR_BY_CMM AS 
   BEGIN


    for cur_r in (
    select circle, 
                   regexp_substr(MP,'[^/]+',1,1)MAINTENANCE_ZONE_NAME,
                   regexp_substr(MP,'[^/]+',1,2)MAINTENANCE_ZONE_CODE,
                   SPAN_TYPE,
                   SPAN_LINK_ID,
                   NE_LENGTH,
                   ROUTE_APPROVED_BY_CMM
                   from TBL_FIBER_INV_CMP_REPORT_MV    
                  where CMM_APPROVED_DATE IS NOT NULL 
                  OR ROUTE_APPROVED_BY_CMM > 0 
                  OR JOB_PROGRESS_FLAG = 1
        )
        
  LOOP

        IF cur_r.ROUTE_APPROVED_BY_CMM >  SELECT ROUND(SUM(NVL(CALCULATED_LENGTH,0)/1000),4) AS NE_LENGTH,
                                           ROUND(SUM(CASE WHEN RJ_CONSTRUCTION_METHODOLOGY NOT LIKE '%AERIAL%' OR RJ_CONSTRUCTION_METHODOLOGY IS  NULL THEN NVL(CALCULATED_LENGTH,0) ELSE 0 END)/1000,4) AS UG_LENGTH
                                           ,ROUND(SUM(CASE WHEN RJ_CONSTRUCTION_METHODOLOGY LIKE '%AERIAL%' THEN NVL(CALCULATED_LENGTH,0) ELSE 0 END)/1000,4) AS AR_LENGTH
                                           FROM NE.MV_SPAN@DB_LINK_NE_VIEWER
        THEN
        
          BEGIN
              UPDATE TBL_FIBER_INV_SIGN_OFF_SHEET 
              SET  FSA_UG = UG_LENGTH,  --- divide 80% of NE_LENGTH
                   FSA_AERIAL = AR_LENGTH    --- divide 20% of NE_LENGTH
              WHERE CUR_R.SPAN_LINK_ID =  RJ_SPAN_ID
                
          END
        
        

    NULL;
  END UPD_UG_AR_BY_CMM;

但我一直在计算百分比明智的比率.

but iam stuck at calculation of percentage wise ratio.

推荐答案

ok，所以最后经过大量的澄清，看起来应该是:

ok, so finally after tons of clarifications, looks like it should be:
