根据 Oracle 中的百分比明智计算更新多个列

Question

注意：使用示例数据和输出更新总问题。

我需要通过与另一个 table 比较来更新一些列，并按百分比更新列。那我走了。

首先，获取 CMM 批准的长度 的查询在下方，其中包含我需要的其他列

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;

上述查询的输出如下图所示

现在是第二部分，计算百分比

案例 1：如果上图中的 CMM 批准长度为 70km，NE 长度（NE，UG，AR len from NE.MV_SPAN@DB_LINK_NE_VIEWER）得出 100Km 则除以 (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。分叉应该在下面更新 table TBL_FIBER_INV_SIGN_OFF_SHEET

和 table 示例数据如下所示：-

案例 2：如果 CMM approved length 和 NE length 相同。例如：70km（UG = 60 Km 和 AR=10Km）然后在 TBL_FIBER_INV_SIGN_OFF_SHEET table 应该更新 UG = 60Km and AR = 10Km.

下面是 table 对 table 的描述。

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;

但我一直卡在百分比计算上。

好的，经过大量的澄清，最终看起来应该是：

when matched then update
   set FSA_UG = src.FSA_UG

Answer 2

根据您的问题解释，更新应该是

update TBL_FIBER_INV_CMP_REPORT_MV 
set UG =  CASE WHEN ROUTE_APPROVED_BY_CMM > 70 AND  NE_LENGTH >= 100 
        THEN NE_LENGTH*0.8 
      WHEN ROUTE_APPROVED_BY_CMM =  NE_LENGTH 
    THEN NE_LENGTH*(60/70)  
    ELSE 0 END

 , AR = CASE WHEN ROUTE_APPROVED_BY_CMM > 70 AND  NE_LENGTH >= 100 
        THEN NE_LENGTH*0.2 
      WHEN ROUTE_APPROVED_BY_CMM =  NE_LENGTH 
    THEN NE_LENGTH*(60/10) 
    ELSE 0 END
