SQL Aggregate function and Subquery issues

Question

Hello,
I'm trying to create an SQL statement that gives the rate of all Urgent surgeries Grouped by sector (i.e Surgery, Radiology), and Fiscal year
To do this I need to divide the sum of surgeries with a state "Urgent" by the total surgeries
In order to pull all the Total surgeries I would need to exclude the surgeries with the state "Cancelled", AND make sure to get rid of duplicates a single surgery may have.
So this is what I came up with, but I'm not able to apply the following formula in SQL for the rate of Urgent surgeries:
TOTAL OF URGENT SURGERIES / TOTAL SURGERIES
Note that the Select statement within the WITH CLAUSE runs successfully when running it separately
With T1 As(
SELECT                          
b."etat",                         
c."secteur",                    
d.annee_fiscale_full,                         
d.periode,
SUM(Count(distinct b."Cle_requete")) OVER (PARTITION BY b."etat", c."secteur", d.annee_fiscale_full, d.periode) AS TOTAL_SURGERIES
FROM vsRequete a,                         
vsEtats b,                         
vsOperation c,                         
periode_financiere d,                         
vstemps_operatoires e                         
WHERE b."etat" <> 'Cancelled'
AND (b."Cle_requete" = a."Cle_vsRequete")                         
AND (c."Cle_requete" = a."Cle_vsRequete")                         
AND (b."Cle_requete" = c."Cle_requete")                         
AND (a."Cle_vsRequete" = e."Cle_requete")                         
AND c."date_operation" = d.per_fina_date                         
GROUP BY                          
b."etat",                         
c."secteur",
--a."type_visite",
d.annee_fiscale_full,                         
d.periode )
SELECT
---- ***NOTE***: SHOULD I BE USING THE FOLLOWING ANALYTIC FUNCTION FOR THE RATE OF URGENT SURGERIES
---- RATIO_TO_REPORT(T1.TOTAL_SURGERIES) OVER () As URGENT_SURGERY_RATE,
T1."secteur",                    
--a."type_visite",
T1.annee_fiscale_full,                         
T1.periode
FROM T1
Where T1."etat" = 'Urgent'
ORDER BY
T1.annee_fiscale_full,                         
T1.periode,                    
T1."secteur";
Thanks for your help

Answer 1

Hi,
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Always say which version of Oracle you're using (for example, 11.2.0.2.0).
See the forum FAQ {message:id=9360002}

If so, how is that counted? Include an example or two in your sample data and results.
FROM vsRequete a,

periode_financiere d,                         
vstemps_operatoires e                         
WHERE b."etat" <> 'Cancelled'This site doesn't like to display the &lt;&gt; inequality operator. Always use the other (equivalent) inequality operator, !=, when posting here.
AND (b."Cle_requete" = a."Cle_vsRequete")                         
AND (c."Cle_requete" = a."Cle_vsRequete")                         
AND (b."Cle_requete" = c."Cle_requete")

Select
----- ***NOTE***: SHOULD I BE USING THE FOLLOWING ANALYTIC FUNCTION FOR THE RATE OF URGENT SURGERIES
------ RATIO_TO_REPORT(T1.TOTAL_SURGERIES) OVER () As URGENT_SURGERY_RATE,That depends on your data, and your desired results. Based on what you've said so far, I think not. It's more likely that you'll want to use a CASE expression to get a count of the 'Urgent' surgeries.
T1."secteur",                    
--a."type_visite",
T1.annee_fiscale_full,                         
T1.periode
FROM T1
Where T1."etat" = 'Urgent'
ORDER BY
T1.annee_fiscale_full,                         
T1.periode,                    
T1."secteur";The forum FAQ {message:id=9360002} explains how to use \ tags to preserve spacing when you post formatted text, such as your query.
It sounds like your problem is similar to this one:
"What percentage of the employees (not counting SALESMEN)  in each department of the scott.emp table are CLERKS?"
Here's one way you might answer that:WITH     got_cnts     AS
     SELECT     deptno
     ,     COUNT ( DISTINCT CASE
                         WHEN job = 'CLERK'
                         THEN ename
                    END
               )               AS clerk_cnt
     ,     COUNT (DISTINCT ename)     AS total_cnt
     FROM     scott.emp
     WHERE     job     != 'SALESMAN'
     GROUP BY deptno
SELECT     deptno
,     clerk_cnt
,     total_cnt
,     100 * clerk_cnt
     / total_cnt     AS clerk_pct
FROM     got_cnts
ORDER BY deptno
Output:DEPTNO CLERK_CNT TOTAL_CNT CLERK_PCT
10 1 3 33.33
20 2 5 40.00
30 1 2 50.00
