Aggregate Function in SQL subquery

Hello,
I am trying to use the following syntax and it is saying I can't use an aggregate function in a subquery. I can't use a GROUP BY in this case because if another field in the project table (such as status) is different, that project will show up twice.
So in this case I am using this syntax to show the most recent quote within the project.
SELECT PROJECT.*, QUOTE.QuoteDate, QUOTE.QuoteCode
FROM PROJECT LEFT JOIN QUOTE ON PROJECT.ProjectID = QUOTE.ProjectID
WHERE QUOTE.QuoteDate=(SELECT Max(Q.QuoteDate) FROM QUOTE Q WHERE Q.ProjectID = PROJECT.ProjectID);
My goal here is to show the most recent quote within each project (there can be multiple revisions of a quote within each project). I want to show other fields such as the status of the quote, but if the status is different between quotes, the GROUP BY on that
field will cause it to be listed more than once. All I want to show is the most recent quote for each project.
Let me know if this isn't clear.
Thanks.

Try the below querySELECT P1.projectID,p1.QuoteDate, Q1.QuoteCode,p1.*
FROM PROJECT P1 inner join (SELECT Q.ProjectID,Max(Q.QuoteDate) QD FROM QUOTE Q group by Q.ProjectID) Q1 on Q1.ProjectID = P1.ProjectID and Q1.QD=P1.QuoteDate-Prashanth

Any difference between distinct and aggregate function in sql query cost???

Hi,
I have executed many sql stmts patterns- such as:
a) using a single table
b) using two tables, using simple joins or outer joins
but i have not noticed any difference in sql stmts in cost and in execution plan....
Anyway, my colleague insists on that using aggregate function is less costly compared to
distinct....(something i have not confirmed, that's why i beleive that they are exactly the same...)
For the above reffered 1st sql pattern.. we could for example use
select distinct deptno
from emp
select count(*), deptno
from emp
group by deptno select distinct owner, object_type from all_objects
select count(*), owner, object_type from all_objects
group by owner, object_typeHave you found any difference between the two ever...????
Note: I use Ora DB 10g v2.
Thank you,
Sim

distinct and aggregate function are for different uses and may give same result but if u r using aggregate function to get distinct records, it will be expensive...

select distinct deptno from scott.dept;

SQL Aggregate Function

I am trying to create a query that will output a single row for each employee. Unfortunately, I can't figure out how to group by the aggregate function itself. Is there a way to do this in SQL Developer? Here is my code at this point:
COL ename FORMAT A25 HEADING Employee|Name
COL salary FORMAT $999,999.99 HEADING Salary
COL comm FORMAT A10 HEADING Commission|Rate
COL earn FORMAT $999,999,999.99 HEADING Sept/2010|Earnings
SELECT DISTINCT e.last_name||', '||e.first_name "ename",salary,
CASE WHEN commission_pct > 0 THEN
commission_pct
ELSE 0
END AS comm,
CASE WHEN commission_pct > 0
AND o.total > 0 THEN
(SUM(o.total)*(commission_pct*.01)+salary)
ELSE salary
END AS earn
FROM (SELECT sales_rep_id,total
FROM s_ord
WHERE date_ordered LIKE '%SEP-10') o
RIGHT OUTER JOIN s_emp e
ON e.id = o.sales_rep_id
GROUP BY e.last_name,e.first_name,e.salary,e.commission_pct,o.total;

PL/SQL : User defined Aggregate Functions ??

Is it possible to create (using whatever language) a user defined aggregate function for transparent usage within sql ?
e.g.
select median(myField) from myTable
or
select empirical_expectation(myField) from myTable
thanx in advance ..

HI,
U can create a stored proc. (PL/SQL) for this and call as any other function.
By using external procedure, U can create shared library in C or C++ and coonect this shared library by using external function/procedure. This will be become user-defined procedure.

How to write SQL query and apply aggregate functions on it

Hello experts,
Iu2019ve a task to write SQL query on tree tables and do inner join on them. Iu2019ve accomplish this task by using T-CODE SQVI. However now I need to write a query and apply SQL functions on it i.e. Add, Count, Max and Min etc. Please can someone tell me how I can write SQL query with aggregate functions in SAP?
Thanks a lot in advance

HI Mr. Cool
you can see the below code for using aggregate functions.
where ARTIST and SEATSOCCU are the field names for which you want to perform these functions.
DATA: TOTAL_ENTRIES TYPE I,
      TOTAL_ATT TYPE I,
      MAX_ATT TYPE I,
      AVG_ATT TYPE I.
SELECT COUNT( DISTINCT ARTIST )
       SUM( SEATSOCCU )
       MAX( SEATSOCCU )
       AVG( SEATSOCCU ) FROM YCONCERT INTO (TOTAL_ENTRIES, TOTAL_ATT,
MAX_ATT, AVG_ATT).

How to Perform an Aggregate Function?

Hi,
I'm trying to define in Designer 6.5 an object with the following select: (example)

Can anyboby explain me the problem and above all how to solve it?

Hi,
You cannot mix different aggregations functions in the same SQL expression: this is a SQL limitation for all databases.
You need to use subselect to achieve your requirement.
See the following example that works on SQL Server:
Select sum(a._count) from
(Select count (distinct cust_id) as _count from Club.dbo.Customer) a

Trying to create a Histogram type/object for aggregate functions

Hi,
I am trying to create an aggregate function that will return a histogram
type.
It doesn't have to be an object that is returned, I don't mind returning
a string but I would like to keep the associative array (or something
else indexed by varchar2) as a static variable between iterations.
I started out with the SecondMax example in
http://www.csis.gvsu.edu/GeneralInfo/Oracle/appdev.920/a96595/dci11agg.htm#1004821
But even seems that even a simpler aggregate function like one strCat
below (which works) has problems because I get multiple permutations for
every combination. The natural way to solve this would be to create an
associative array as a static variable as part of the Histogram (see
code below). However, apparently Oracle refuses to accept associate
arrays in this context (PLS-00355 use of pl/sql table not allowed in
this context).
If there is no easy way to do the histogram quickly can we at least get
something like strCat to work in a specific order with a "partition by
... order by clause"? It seems that even with "PARALLEL_ENABLE"
commented out strCat still calls merge for function calls like:
select hr,qtr, count(tzrwy) rwys,
noam.strCat(cnt) rwycnt,
noam.strCat(tzrwy) config,
sum(cnt) cnt, min(minscore) minscore, max(maxscore) maxscore from
ordrwys group by hr,qtr
Not only does this create duplicate entries in the query result like
"A,B,C" and "A,C,B" it seems that the order in rwycnt and config are not
always the same so a user can not match the results based on their
order.
The difference between my functions and functions like sum and the
secondMax demonstrated in the documentation is that secondMax does not
care about the order in which it gets its arguments and does not need to
maintain an ordered set in order to return the correct results. A good
example of a built in oracle function that does care about all its
arguments and probably has to maintain a similar data structure to the
one I want is the PERCTILE_DISC function. If you can find the code for
that function (or something like it) and forward a reference to me that
in itself would be very helpful.
Thanks,
K.Dingle

Should your query be a valid SQL query?
I can't think that the query you have would be valid in a SQL plus window.

A function in a subquery is call too many times.

Dear all,
I'm struggling to understand why a function in a subquery is called too many times.
Let me explain with an example:
create or replace function all_emp (v_deptno in number)
return varchar2
as
v_all_emp varchar2(2000);
begin
    dbms_output.put_line ('function called');
    for i in (select * from emp where deptno = v_deptno) loop
        v_all_emp := v_all_emp || i.ename || '; ';
    end loop;
return v_all_emp;
end;
-- running just the subquery, calls the function all_emp only 4 times (once for each row in table dept)
select
    d.deptno,
    d.dname,
    all_emp(d.deptno) f_all_emp
    from dept d;
-- running the whole query, using regexp to split the value of f_all_emp into separate fields, causes that function all_emp is called 28 times, thus 6 times for each row!!
select tmp.*,
regexp_substr(f_all_emp,'[^;]*',1,1) emp1,
regexp_substr(f_all_emp,'[^;]*',1,3) emp2,
regexp_substr(f_all_emp,'[^;]*',1,5) emp3,
regexp_substr(f_all_emp,'[^;]*',1,7) emp4,
regexp_substr(f_all_emp,'[^;]*',1,9) emp5,
regexp_substr(f_all_emp,'[^;]*',1,11) emp6
from
    (select
    d.deptno,
    d.dname,
    all_emp(d.deptno) f_all_emp
    from dept d) tmp
;I don't understand why Oracle is calling my function 28 times in this example, 4 times should be sufficient.
Is there a way to force that the subquery is materialized first?
Little background:
Above function / query is of course a simple example.
Actually I have pretty complex function, embedding in a subquery.
The subquery is already slow (2 min to run), but when I want to split the result of the funciton in multiple (approx 20) fields it's over an hour due to above described behaviour.

Optimizer merges in-line view and query results in:
select d.deptno,
        d.dname,
        all_emp(d.deptno) f_all_emp
        regexp_substr(all_emp(d.deptno),'[^;]*',1,1) emp1,
        regexp_substr(all_emp(d.deptno),'[^;]*',1,3) emp2,
        regexp_substr(all_emp(d.deptno),'[^;]*',1,5) emp3,
        regexp_substr(all_emp(d.deptno),'[^;]*',1,7) emp4,
        regexp_substr(all_emp(d.deptno),'[^;]*',1,9) emp5,
        regexp_substr(all_emp(d.deptno),'[^;]*',1,11) emp6
from dept d
/That's why function is called 28 times. We can see it from explain plan:
SQL> explain plan for
2 select tmp.*,
3          regexp_substr(f_all_emp,'[^;]*',1,1) emp1,

Issue in pivot while using aggregate functions

when I use this below query in oracle sql developer
------------->select sum(round(8.08/0.54,2)*30) from dual.
i am getting result as 448.8.it is a correct value
but i use this below queries in pivot as same like above query i am getting result of doubled value 914.4.
PIVOT
SUM(round(ROUND(sellout,2)/6,2)) AS LAST_6_MON_SELL_OUT,
SUM(ROUND(inventory,2)) AS INVENTORY_INTINS_1,
Sum(round(ROUND(inventory,2)/round(ROUND(sellout,2)/6,2),2)*30) As Stockperday
FOR PRODUCT IN (56,78)
actually i am getting value for SUM(round(ROUND(sellout,2)/6,2)) is 0.54,*SUM(ROUND(inventory,2))* is 8.08 i the above query ,but i am getting wrong value for this aggregate function Sum(round(ROUND(inventory,2)/round(ROUND(sellout,2)/6,2),2)30)* as 914.4.but actual value is 448.8
why this problem.can anybody explain me.why this problem

Why doesn't PIVOT clause work with COLLECT aggregate function in 11g ?

Hello all !
I am really puzzled as to what is considered an aggregate function in the context of the PIVOT clause in 11g.
I have been toying with quite a few things related to collections lately and this arose as an aside :
CREATE TABLE TEST_COLL
   NODE_ID    VARCHAR2(15 CHAR) NOT NULL,
   NODE_VALUE VARCHAR2(45 CHAR) NOT NULL,
   NODE_LEVEL NUMBER(1)         NOT NULL
CREATE OR REPLACE TYPE TREE_NODE AS OBJECT
   NODE_KEY VARCHAR2( 15 CHAR),
   NODE_NAME VARCHAR2(127 CHAR)
CREATE OR REPLACE TYPE TREE_NODES AS TABLE OF TREE_NODE NOT NULL;At this stage I am sure we all agree that the query
SELECT NODE_LEVEL,
       CAST(COLLECT(TREE_NODE(NODE_ID, NODE_VALUE)) AS TREE_NODES) AS NODES
FROM TEST_COLL
GROUP BY NODE_LEVEL;is perfectly valid as the COLLECT function is an aggregate function according to the [Official Documentation|http://docs.oracle.com/cd/E11882_01/server.112/e10592/functions031.htm#i1271564]
But then, one of the following two queries should work
SELECT CAST(REGION_NODES     AS TREE_NODES) AS REGIONS,
       CAST(DEPARTMENT_NODES AS TREE_NODES) AS DEPARTMENTS,
       CAST(AREA_NODES       AS TREE_NODES) AS AREAS,
       CAST(CENTRE_NODES     AS TREE_NODES) AS CENTRES
FROM (SELECT NODE_LEVEL, TREE_NODE(NODE_ID, NODE_VALUE) AS NODE
          FROM TREE_COLL
PIVOT (COLLECT(NODE) FOR NODE_LEVEL IN (1 AS REGION_NODES,
                                         2 AS DEPARTMENT_NODES,
                                         3 AS AREA_NODES,
                                         4 AS CENTRE_NODES
or (better)
SELECT REGION_NODES     AS REGIONS,
       DEPARTMENT_NODES AS DEPARTMENTS,
       AREA_NODES       AS AREAS,
       CENTRE_NODES     AS CENTRES
FROM (SELECT NODE_LEVEL, TREE_NODE(NODE_ID, NODE_VALUE) AS NODE
          FROM TREE_COLL
PIVOT (CAST(COLLECT(NODE) AS TREE_NODES) FOR NODE_LEVEL IN (1 AS REGION_NODES,
                                                             2 AS DEPARTMENT_NODES,
                                                             3 AS AREA_NODES,
                                                             4 AS CENTRE_NODES
       );yet, both fail with
ORA-56902: expect aggregate function inside pivot operationInvestigating further, I found the same behaviour when using XMLAGG as the aggregate function in the PIVOT clause.
Is this normal ? And if it is, is there any other way to achieve the result I was anticipating ?

Most likely a bug. But you can bypass it by using any other aggregate making sure group consists of a single row and apply collect to a pivoted value. Yes, the cost is double aggregation. And also there is another cost - you would need to create MAP member function otherwise aggreations like MAX/MIN, etc. will not work:
CREATE OR REPLACE TYPE TREE_NODE AS OBJECT
   NODE_KEY VARCHAR2( 15 CHAR),
   NODE_NAME VARCHAR2(127 CHAR),
   map member function f return varchar2
Type created.
CREATE OR REPLACE TYPE BODY TREE_NODE AS
map member function f return varchar2 is
begin
     return NODE_NAME;
end f;
end;
Type body created.
CREATE OR REPLACE TYPE TREE_NODES AS TABLE OF TREE_NODE NOT NULL
Type created.

How can I use User-Defined Aggregate Functions in Timesten 11? such as ODCI

Hi
we are using Timesten 11 version and as per the documentation, it doesn't support User-Defined Aggregate Functions.
So we are looking for alternatives to do it. Could you please provide your expert voice on this.
Thanks a lot.
As the following:
create or replace type strcat_type as object (
cat_string varchar2(32767),
static function ODCIAggregateInitialize(cs_ctx In Out strcat_type) return number,
member function ODCIAggregateIterate(self In Out strcat_type,value in varchar2) return number,
member function ODCIAggregateMerge(self In Out strcat_type,ctx2 In Out strcat_type) return number,
member function ODCIAggregateTerminate(self In Out strcat_type,returnValue Out varchar2,flags in number) return
number
How can I use User-Defined Aggregate Functions in Timesten 11? such as ODCIAggregateInitialize ?

Dear user6258915,
You absolutely right, TimesTen doesnt support object types (http://docs.oracle.com/cd/E13085_01/doc/timesten.1121/e13076/plsqldiffs.htm) and User-Defined Aggregate Functions.
Is it crucial for your application? Could you rewrite this functionality by using standart SQL or PL/SQL?
Best regards,
Gennady
