To use "analytic function" at "recursive with clause"
http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_10002.htm#i2077142
The recursive member cannot contain any of the following elements:
・An aggregate function. However, analytic functions are permitted in the select list.
OK I will use analytic function at The recursive member :-)

How to use analytic function with aggregate function
hello
can we use analytic function and aggrgate function in same qurey? i tried to find any example on Net but not get any example how both of these function works together. Any link or example plz share with me
Edited by: Oracle Studnet on Nov 15, 2009 10:29 PMselect
t1.region_name,
t2.division_name,
t3.month,
t3.amount mthly_sales,
max(t3.amount) over (partition by t1.region_name, t2.division_name)
max_mthly_sales
from
region t1,
division t2,
sales t3
where
t1.region_id=t3.region_id
and
t2.division_id=t3.division_id
and
t3.year=2004
Source:http://www.orafusion.com/art_anlytc.htm
Here max (aggregate) and over partition by (analytic) function is in same query. So it means we can use aggregate and analytic function in same query and more than one analytic function in same query also.

i have this table below
CREATE TABLE table1
( cust_name VARCHAR2 (10)
, txn_id NUMBER
, txn_date DATE
, country VARCHAR2 (10)
, flag number
, CONSTRAINT key1 UNIQUE (cust_name, txn_id)
INSERT INTO table1 (cust_name, txn_id, txn_date,country,flag) VALUES ('Peter', 9870,TO_DATE ('15-Jan-2011', 'DD-Mon-YYYY'), 'Iran', 1);
INSERT INTO table1 (cust_name, txn_id, txn_date,country,flag) VALUES ('Peter', 9871,TO_DATE ('16-Jan-2011', 'DD-Mon-YYYY'), 'China', 1);
INSERT INTO table1 (cust_name, txn_id, txn_date,country,flag) VALUES ('Peter', 9872,TO_DATE ('17-Jan-2011', 'DD-Mon-YYYY'), 'China', 1);

INSERT INTO table1 (cust_name, txn_id, txn_date,country,flag) VALUES ('Peter', 9878,TO_DATE ('26-Jan-2011', 'DD-Mon-YYYY'), 'Korea', 0);
INSERT INTO table1 (cust_name, txn_id, txn_date,country,flag) VALUES ('Peter', 9811,TO_DATE ('17-Jan-2011', 'DD-Mon-YYYY'), 'China', 0);
INSERT INTO table1 (cust_name, txn_id, txn_date,country,flag) VALUES ('Peter', 9854,TO_DATE ('13-Jan-2011', 'DD-Mon-YYYY'), 'Taiwan', 0);
The requirement is to create an additional column in the resultset with country name where the customer has done the maximum number of transactions
(with transaction flag 1). In case we have two or more countries tied with the same count, then we need to select the country (among the tied ones)
where the customer has done the last transaction (with transaction flag 1)
e.g. The count is 2 for both 'China' and 'Japan' for transaction flag 1 ,and the latest transaction is for 'Japan'. So the new column should contain 'Japan'
CUST_NAME TXN_ID TXN_DATE COUNTRY FLAG country_1
Peter 9811 17-JAN-11 China 0 Japan
Peter 9854 13-JAN-11 Taiwan 0 Japan
Peter 9870 15-JAN-11 Iran 1 Japan

Hi all,
I am using ODI 11g(11.1.1.3.0) and I am trying to make an interface using analytic functions in the column mapping, something like below.
sum(salary) over (partition by .....)
The problem is that when ODI saw sum it assumes this as an aggregate function and puts group by. Is there any way to make ODI understand it is not an aggregate function?
I tried creating an option to specify whether it is analytic or not and updated IKM with no luck.
<%if ( odiRef.getUserExit("ANALYTIC").equals("1") ) { %>
<% } else { %>
<%=odiRef.getGrpBy(i)%>
<%=odiRef.getHaving(i)%>
<% } %>
Thanks in advanceThanks for the reply.
But I think in ODI 11g getFrom() function is behaving differently, that is why it is not working.
When I check out the A.2.18 getFrom() Method from Substitution API Reference document, it says
Allows the retrieval of the SQL string of the FROM in the source SELECT clause for a given dataset. The FROM statement is built from tables and joins (and according to the SQL capabilities of the technologies) that are used in this dataset.
I think getfrom also retrieves group by clause, I create a step in IKM just with *<%=odiRef.getFrom(0)%>* and I can see that even that query generated has a group by clause -
Restrict Query Resultset which uses Analytic Function
Gents,
Problem Definition: Using Analytic Function, get Total sales for the Product P1
and Customer C1 [Total sales for the customer itself] in one line.
I want to restrict the ResultSet of the query to Product P1,
please look at the data below, queries and problems..
Data
Customer Product Qtr Sales
C1 P1 19991 100.00
C1 P1 19992 125.00
C1 P1 19993 175.00
C1 P1 19994 300.00
C1 P2 19991 100.00
C1 P2 19992 125.00
C1 P2 19993 175.00
C1 P2 19994 300.00
C2 P1 19991 100.00
C2 P1 19992 125.00
C2 P1 19993 175.00
C2 P1 19994 300.00
Problem, I want to display....
Customer Product ProdSales CustSales
C1 P1 700 1400
But Without using outer query, i.e. please look below for the query that
returns this reult with two select, I want this result in one query only..
Select * From ----*** want to avoid this... ***----
(Select Customer,Product,
Sum(Sales) ProdSales,
Sum(Sum(Sales)) Over(Partition By Customer) CustSales
From t1
Where customer='C1')
Where
Product='P1' ;
Also, I want to avoid Hard coding of P1 in the select clause....
I mean, I can do it in one shot/select, but look at the query below, it uses
P1 in the select clause, which is No No!! P1 is allowed only in Where or Having ..
Select Customer,Decode(Product, 'P1','P1','P1') Product,
Decode(Product,'P1',Sales,0) ProdSales,
Sum(Sum(Sales)) Over (Partition By Customer ) CustSales
From t1
Where customer='C1' ;
This will get me what I want, but as I said earlier, I want to avoid using P1 in the
Select clause..
Goal is to Avoid using
1-> Two Select/Outer Query/In Line Views
2-> Product 'P1' in the Select clause...
Thanks
-Dhaval RasaniaI don't understand goal number 1 of not using an inline view.
What is the harm? -
Hi all,
I want an help in creating my SQL query to extract the data described below:
I have one table example test containing data like below:
ID Desc Status
1 T1 DEACTIVE
2 T2 ACTIVE
3 T3 SUCCESS
4 T4 DEACTIVE
The thing i want to do is selecting all lines with ACTIVE status in this table but is there is no ACTIVE status, my query will give me the last line with DEACTIVE status.
Can I do this in one query by using analytical function for example, if yes can yiu help me on thaht query.
regards,
RaluceHi, Raluce,
Here's one way to do that:
WITH got_r_num AS
SELECT deptno, ename, job, hiredate
, ROW_NUMBER () OVER ( PARTITION BY deptno
ORDER BY job
, hiredate DESC
) AS r_num
FROM scott.emp
WHERE job IN ('ANALYST', 'CLERK')
SELECT deptno, ename, job, hiredate
FROM got_r_num
WHERE job = 'ANALYST'
OR r_num = 1
ORDER BY deptno
Since I don't have a sample version of your table, I used scott.emp to illustrate.
Output:
DEPTNO ENAME JOB HIREDATE
10 MILLER CLERK 23-JAN-82
20 SCOTT ANALYST 19-APR-87
20 FORD ANALYST 03-DEC-81
30 JAMES CLERK 03-DEC-81
This query finds all ANALYSTs in each department, regardless of how many there are. (Deptno 20 happens to have 2 ANALYSTs.) If there is no ANALYST in a department, then the most recently hired CLERK is included. (Deptnos 10 and 30 don't have any ANALYSTs.)
This "partitions", or sub-divides, the table into separate units, one for each department. In the problem you posted, it looks like you want to operate in the entire table, without sub-dividing it in any way. To do that, just omit the PARTITION BY clause in the analytic ROW_NUMBER function, like this:
WITH got_r_num AS
SELECT deptno, ename, job, hiredate
, ROW_NUMBER () OVER ( -- PARTITION BY deptno
ORDER BY job
, hiredate DESC
) AS r_num
FROM scott.emp
WHERE job IN ('ANALYST', 'CLERK')
SELECT deptno, ename, job, hiredate
FROM got_r_num
WHERE job = 'ANALYST'
OR r_num = 1
ORDER BY deptno -
Using analytical function to calculate concurrency between date range
Folks,
I'm trying to use analytical functions to come up with a query that gives me the
concurrency of jobs executing between a date range.
For example:
JOB100 - started at 9AM - stopped at 11AM
JOB200 - started at 10AM - stopped at 3PM
JOB300 - started at 12PM - stopped at 2PM
The query would tell me that JOB1 ran with a concurrency of 2 because JOB1 and JOB2
were running started and finished within the same time. JOB2 ran with the concurrency
of 3 because all jobs ran within its start and stop time. The output would look like this.
JOB START STOP CONCURRENCY
=== ==== ==== =========
100 9AM 11AM 2
200 10AM 3PM 3
300 12PM 2PM 2
I've been looking at this post, and this one if very similar...

... Kindly note, I am still learning how to use analytic functions.That doesn't matter; analytic functions won't help in this problem. The aggregate SUM function is all you need.
But what do you need to GROUP BY? What is each row of the result set going to represent? A placeid? Yes, each row will represent only one placedid, but it's going to be divided further. You want a separate row of output for every placeid and week, so you'll want to GROUP BY placeid and week. You don't want to GROUP BY the raw issuedate; that would put March 3 and March 4 into separate groups. And you don't want to GROUP BY failures; that would mean a row with 3 failures could never be in the same group as a row with 9 failures.
This gets the output you posted from the sample data you posted:
SELECT placeid
, TO_CHAR ( TRUNC (issuedate, 'IW')
, 'MM/DD/YYYY'
) || ' - '|| TO_CHAR ( TRUNC (issuedate, 'IW') + 6
, 'MM/DD/YYY'
) AS issueperiod
, SUM (failures) AS sumfailures
FROM temp_one
GROUP BY placeid
, TRUNC (issuedate, 'IW')
;You could use a sub-query to compute TRUNC (issuedate, 'IW') once. The code would be about as complicated, efficiency probably won't improve noticeably, and the the results would be the same. -
Using analytic function in a view
Hello to all
Sorry If I use this thread
sql not merge using analytic functions
for my question,
From example you write and from Tom explain is not possible create a view on analytic function?
Thanks and sorry againI think what you'll discover is that if you apply the function over the result set, the initial SQL might be quicker,
for example, this is a test I did with a large dictionary view:
select tp.Table_Name
,tp.Partition_Name
from
select tbl.Table_Name as Table_Name
,tbl.Partition_Date as dt
,row_number() over (partition by dtp.table_Name order by dtp.Partition_Name desc) rn
from (
select /*+ all_rows */
dtp.Table_Name
,dtp.Partition_name
from dba_tab_partitions dtp
where dtp.Partition_Name like 'Y____\_Q_\_M__\_D__' escape '\'
and dtp.Table_Owner = 'APPS'
and dtp.Table_name not like '%$%'
and dtp.Table_Name like '%'
) tbl
) tp
where tp.rn = 1
select Table_Name
,Partition_Name
from (
select /*+ all_rows */
dtp.Table_Name
,row_number() over (partition by tbl.table_Name order by tbl.Partition_Name desc) rn
from dba_tab_partitions dtp
where dtp.Partition_Name like 'Y____\_Q_\_M__\_D__' escape '\'
and dtp.Table_Owner = 'APPS'
and dtp.Table_name not like '%$%'
and dtp.Table_Name '%'
) tbl
where rn = 1I found the former to be quicker.
I think ask tom was saying a lot more, but included something similar,

Let us discussion "non recursive with clause" usage
I think there are 3 "non recursive with clause" usage.
My question is do you know more "non recursive with clause" usage ?Another option is to use it to materialize remote data on the fly. Especially in combination with the materialize hint.
I think I used this tecnique once, but can't find the proper example anymore. Very simplified it could looked like this:
with fetchData as (Select /*+materialize */ * from myremoteTable@databaselink where status = 'CURRENT')
select *
from fetchdata r
full outer join localData l on r.id = r.id
where l.status = 'CURRENT'
;From 11g onwards: use the with clause to create better column names in larger select from dual combinations.
Not sure with that results in a suitable use case.
So instead of
with orders as
(select 1 id , 173 order#, 'John' customer, 'America' region from dual union all
select 2 id , 170 order#, 'Paul' customer, 'UK' region from dual union all
select 3 id , 240 order#, 'Hans' customer, 'Europe' region from dual union all
select 4 id , 241 order#, 'Francois' customer, 'Europe' region from dual )
select * from orders;you can now write
with
orders (id, order#, customer,region) as
(select 1 , 173 , 'John' , 'America' from dual union all
select 2 , 170 , 'Paul' , 'UK' from dual union all
select 3 , 240 , 'Hans' , 'Europe' from dual union all
select 4 , 241 , 'Francois' , 'Europe' from dual )
select * from orders;THis makes it a little easier to create tase data useing some excel sheet I guess. -
Hi All,
I am using oracle 11.2.0.4
I m using this for learning purpose
Below is my table and insert statement
CREATE TABLE NUMBERS(NUM NUMBER);
INSERT INTO NUMBERS VALUES(1);
INSERT INTO NUMBERS VALUES(2);
INSERT INTO NUMBERS VALUES(3);
INSERT INTO NUMBERS VALUES(4);
WITH RSFC(ITERATION,RUNNING_FACTORIAL) AS
(SELECT NUM AS ITERATION,
1 AS RUNNING_FACTORIAL
FROM NUMBERS
WHERE NUM=1
UNION ALL
SELECT R.ITERATION+1,
R.RUNNING_FACTORIAL * B.NUM
FROM RSFC R INNER JOIN NUMBERS B
ON (R.ITERATION+1) + B.NUM
SELECT ITERATION,RUNNING_FACTORIAL
FROM RSFC
I am learning recursive with clause
when I am trying to execute the query I am getting
ORA-00920 : invalid realtional operator
what is wrong in this query,please help me
Thanks and Regrds,

The error actually has nothing to do with the WITH clause.
Join conditions (that is, the conditions following the ON keyword) must be expressions that evaluate to TRUE or FALSE. The join condition you posted, however
(R.ITERATION+1) + B.NUM
evaluates to a NUMBER. The following would be a valid join condition:
(R.ITERATION+1) = B.NUM
but I have no idea if that's what you wanted or not. -
Should I use Analytic functions ?
Hello,
I have a table rci_dates with the following structure (rci_id,visit_id,rci_name,rci_date).
A sample of data in this table is as given below.
1,101,'FIRST VISIT', '2010-MAY-01',
2,101,'FIRST VISIT', '2010-MAY-01'
3,101,'FIRST VISIT', '2010-MAY-01'
4,101,'FIRST VISIT', '2010-MAY-01'
5,102,'SECOND VISIT', '2010-JUN-01',
6,102,'SECOND VISIT', '2010-JUN-01'
7,102,'SECOND VISIT', '2010-JUN-01'
8,102,'SECOND VISIT', '2010-JUL-01'
I want to write a query which returns me the records which are similar to the record with rc_id =8 since the rci_date is different within the visit_id 102. Where as in Visit_id 101 the rci_dates are all same so it should not be displayed in the output returned by my query.
How can I do this ? Should I be using analytic functions. Can someone please let me know.
Thanksok i have created the table and inserted the data. but it appears that the data are the output you are expecting, they all the same visit_id.
