How do I find the SUM of the following rows in SQL? - sql

Question

I have the following query in SQL :
SELECT LOCATION_CODE AS "Location",
AUTHORIZATION_STATUS AS "Authorization Status",
COUNT(authorization_status) AS "Requisition Lines Count",
imcb.SEGMENT1 AS "CATEGORY"
FROM apps.po_requisition_headers_all prha
JOIN apps.po_requisition_lines_all prla
ON prla.REQUISITION_HEADER_ID = prha.REQUISITION_HEADER_ID
AND (prha.CANCEL_FLAG = 'N' OR prha.CANCEL_FLAG IS NULL )
JOIN INV.MTL_CATEGORIES_B imcb
ON prla.category_id = imcb.category_id
JOIN HR.PER_ALL_PEOPLE_F P
ON P.person_id = prha.preparer_id
JOIN apps.HR_LOCATIONS ahl
ON prla.deliver_to_location_id = ahl.location_id
JOIN apps.FND_USER afu
ON p.person_id = afu.employee_id
WHERE prla.CREATION_DATE >= '13-JUN-14'
AND P.effective_start_date >=
ALL (SELECT p_temp.EFFECTIVE_START_DATE
FROM HR.PER_ALL_PEOPLE_F p_temp
WHERE P.PERSON_ID = p_temp.PERSON_ID)
AND P.current_employee_flag = 'Y'
/* AND AUTHORIZATION_STATUS = 'APPROVED' */
AND ahl.country IN ( 'US', 'CA', 'MX' ) /* countries in NA */
AND imcb.SEGMENT1 = 'NONBOM'
GROUP BY imcb.SEGMENT1 , authorization_status, LOCATION_CODE
ORDER BY Location_code ASC
And it yields the following output :
However, I would like it to have the total Count for a single location, regardless of Authorization Status. So , it should look like so :
Liberty Lake 826
Rather than
Liberty Lake 767
Liberty Lake 29
Liberty Lake 29
etc
How do I generate this result? I tried adding in a SUM like so:
sum(authorization_status),
but this gives me the following error:
ORA-01722: invalid number

Answer 1

Use a group by rollup instead of just group by
You'll get the current summaaries you have now plus rolled up summaries:
GROUP BY imcb.SEGMENT1, LOCATION_CODE, ROLLUP (authorization_status)
If you don't want any of the more detailed summaries, then remove authorization_status from both your select and group by lists.

Answer 2

You're trying to call the aggregate function SUM on a text field, which is why you are getting that error. SUM is for adding numeric values together. COUNT is used to count the occurrences of rows in that grouping scope. What I think you actually want to do is remove Authorization status from your query, so it would actually be:
SELECT LOCATION_CODE AS "Location",
COUNT(authorization_status) AS "Requisition Lines Count",
imcb.SEGMENT1 AS "CATEGORY"
FROM apps.po_requisition_headers_all prha
JOIN apps.po_requisition_lines_all prla
ON prla.REQUISITION_HEADER_ID = prha.REQUISITION_HEADER_ID
AND (prha.CANCEL_FLAG = 'N' OR prha.CANCEL_FLAG IS NULL )
JOIN INV.MTL_CATEGORIES_B imcb
ON prla.category_id = imcb.category_id
JOIN HR.PER_ALL_PEOPLE_F P
ON P.person_id = prha.preparer_id
JOIN apps.HR_LOCATIONS ahl
ON prla.deliver_to_location_id = ahl.location_id
JOIN apps.FND_USER afu
ON p.person_id = afu.employee_id
WHERE prla.CREATION_DATE >= '13-JUN-14'
AND P.effective_start_date >=
ALL (SELECT p_temp.EFFECTIVE_START_DATE
FROM HR.PER_ALL_PEOPLE_F p_temp
WHERE P.PERSON_ID = p_temp.PERSON_ID)
AND P.current_employee_flag = 'Y'
/* AND AUTHORIZATION_STATUS = 'APPROVED' */
AND ahl.country IN ( 'US', 'CA', 'MX' ) /* countries in NA */
AND imcb.SEGMENT1 = 'NONBOM'
GROUP BY imcb.SEGMENT1 , LOCATION_CODE
ORDER BY Location_code ASC
Note that I removed it from both my SELECT list and my GROUP BY clause.
