问题
NOTE: Updating total question with sample data and output.
I need to update some columns by comparing from another table and update the columns percentage wise. So here I go.
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;
and the output of above query looks like this below image
Now comes the second part which is calculation of the percentage wise ratio
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)
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
and the table sample data looks like below:-
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.
Below are the table description of both the tables.

SPAN_TYPE NVARCHAR2(20)
NE_LENGTH NUMBER
HOTOOFFERDATE DATE
FSA_UG NUMBER
FSA_AERIAL NUMBER Please help me to achieve this procedure of what ever will be easy
UPDATE To get UG_length and AR_length from NE.MV_SPAN@DB_LINK_NE_VIEWER here is the logic
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)
Also some common columns from all the tables are
SPAN_LINK_ID from TBL_FIBER_INV_SIGN_OFF_SHEET table
SPAN_LINK_ID from TBL_FIBER_INV_CMP_REPORT_MV table
AND
RJ_LINK_ID, RJ_SPAN_ID, CALCULATED_LENGTH, RJ_CONSTRUCTION_METHODOLOGY FROM NE.MV_SPAN@DB_LINK_NE_VIEWER table
THE LOGIC WHICH I TRIED TILL NOW
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;but iam stuck at calculation of percentage wise ratio.
回答1:
ok, so finally after tons of clarifications, looks like it should be:
+update: duplicates
merge into TBL_FIBER_INV_SIGN_OFF_SHEET DST
using (
-- Source: original query
with mv as (
select * from (
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, -- ? NE_LENGTH - 1
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 (
SELECT
ROUND(SUM(NVL(CALCULATED_LENGTH,0)/1000),4) AS NE_LENGTH -- ? NE_LENGTH - 2
,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
)
select
mv.*
--,cpt.*
,case when mv.CMM_APPROVED_LENGTH > pct.NE_LENGTH then 0.8 * pct.UG_length
when mv.CMM_APPROVED_LENGTH = pct.NE_LENGTH then 0.9 * pct.UG_length
end as FSA_UG
,case when mv.CMM_APPROVED_LENGTH > pct.NE_LENGTH then 0.2 * pct.AR_LENGTH
when mv.CMM_APPROVED_LENGTH = pct.NE_LENGTH then 0.1 * 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
,FSA_AERIAL = src.FSA_AERIAL;
回答2:
Based on your question explanation the update should be
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
