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:
+更新:重复
merge into TBL_FIBER_INV_SIGN_OFF_SHEET DST
using (
-- Source: original query
with mv as (
select * from (
select

ROUTE_APPROVED_BY_CMM as CMM_APPROVED_LENGTH,
row_number()over(partition by SPAN_LINK_ID order by ROUTE_APPROVED_BY_CMM) rn
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
)
where rn=1
)
,pct as (

,case when mv.CMM_APPROVED_LENGTH > pct.NE_LENGTH then 0.8 * pct.UG_length

end as FSA_UG
,case when mv.CMM_APPROVED_LENGTH > pct.NE_LENGTH then 0.2 * pct.AR_LENGTH

end as FSA_AERIAL
from mv, pct
-- end of Source query
) SRC
on ( dst.SPAN_LINK_ID = src.SPAN_LINK_ID )
when matched then update
set FSA_UG = src.FSA_UG
