Results of SQL grouping not as intended - sql

Question

Intro Details:
I have an issue with a query for Oracle SQL Developer using client 12c. I've researched several other questions on SO as well as searched Google for an answer to this, but ultimately the answers to all have been to include all columns without aggregate functions in the GROUP BY clause.
What I want is to get a single result for each category (PG.CAT) per year, week, and day (FD.YEAR, FD.WEEK, and FD.DT respectively). I want to sum the units, hours, errors (GE.QTY), and total hours. I also perform multiplication and division on two columns and join up to four other tables.
Query:
`SELECT
FD.YEAR,
FD.WEEK,
PG.DT,
PG.CAT,
SUM(PG.UNITS) AS UNITS,
SUM(PG.HOURS) AS HOURS,
PM.MTM,
PM.MTM * PG.HOURS AS ADJ_MTM,
(PG.UNITS / (PM.MTM * PG.HOURS)) AS PERC_STANDARD,
SUM(CASE WHEN GE.QTY IS NULL THEN 0 ELSE GE.QTY END) AS QTY,
SUM(WH.TOTALHOURS) AS TOTALHOURS
FROM
PROD_GUNS PG
INNER JOIN PROD_MTM PM
ON PG.CAT = PM.CATEGORY
AND PM.DEPTNO = '018'
AND PG.DT BETWEEN PM.START_DT AND PM.END_DT
INNER JOIN FISCAL_DATES_DAYS FD
ON PG.DT = FD.DT
LEFT OUTER JOIN PROD_GUNS_ERRORS GE
ON PG.EID = GE.EID
AND PG.DT = GE.DT
INNER JOIN WEEKLY_HOURS WH
ON FD.WEEK = WH.DT_WEEK
AND FD.YEAR = WH.DT_YEAR
AND PG.EID = WH.EEXX31
GROUP BY
FD.YEAR,
FD.WEEK,
PG.DT,
PG.CAT,
PM.MTM,
PM.MTM * PG.HOURS,
(PG.UNITS / ( PM.MTM * PG.HOURS))
HAVING
FD.YEAR = '2015'
AND FD.WEEK = '1'
AND PG.DT = '29-DEC-14'
AND PG.CAT = 'Picking'
ORDER BY
PG.DT;`
Actual Result:
2015 1 29-DEC-14 Picking 46 0.5 68 34 1.35294117647058823529411764705882352941 0 32.21
2015 1 29-DEC-14 Picking 831 7.72 68 524.96 1.58297775068576653459311185614142029869 0 29.35
Intended Result:
2015 1 20-Dec-14 Picking 877 8.22 68 558.96 1.21654501216545 0 61.59
Question:
With the aggregates and grouping that I have above, why would this not be giving me the intended result? Thank you all in advance for any guidance provided.

Answer 1

Try to SUM/AVG (depending on what you need) PM.MTM * PG.HOURS AS ADJ_MTM and (PG.UNITS / (PM.MTM * PG.HOURS)) AS PERC_STANDARD, not group by them:
SELECT
FD.YEAR,
FD.WEEK,
PG.DT,
PG.CAT,
SUM(PG.UNITS) AS UNITS,
SUM(PG.HOURS) AS HOURS,
PM.MTM,
SUM(PM.MTM * PG.HOURS )AS ADJ_MTM,
SUM((PG.UNITS / (PM.MTM * PG.HOURS))) AS PERC_STANDARD,
SUM(CASE WHEN GE.QTY IS NULL THEN 0 ELSE GE.QTY END) AS QTY,
SUM(WH.TOTALHOURS) AS TOTALHOURS
FROM
PROD_GUNS PG
INNER JOIN PROD_MTM PM
ON PG.CAT = PM.CATEGORY
AND PM.DEPTNO = '018'
AND PG.DT BETWEEN PM.START_DT AND PM.END_DT
INNER JOIN FISCAL_DATES_DAYS FD
ON PG.DT = FD.DT
LEFT OUTER JOIN PROD_GUNS_ERRORS GE
ON PG.EID = GE.EID
AND PG.DT = GE.DT
INNER JOIN WEEKLY_HOURS WH
ON FD.WEEK = WH.DT_WEEK
AND FD.YEAR = WH.DT_YEAR
AND PG.EID = WH.EEXX31
GROUP BY
FD.YEAR,
FD.WEEK,
PG.DT,
PG.CAT,
PM.MTM
HAVING
FD.YEAR = '2015'
AND FD.WEEK = '1'
AND PG.DT = '29-DEC-14'
AND PG.CAT = 'Picking'
ORDER BY
PG.DT;
