Recursive, hierachical query problem

Hi!
I have a hierachical SQL query using "connect by" that result in the following dataset (simplified to get down to the point):
ID       | Parent |   IsData
A        |        |    N
A1     |   A    |    N
A2     |   A    |    N
    X1   |   A2   |    Y
B        |        |    N
B1     |   B    |    N
    X2   |   B1   |    Y
B2     |   B    |    N
C        |        |    N
C1     |   C    |    N     There are data entries (X1 and X2) and structural (An, Bn, Cn) entries. Some nodes of the structure tree have data entries as childs, some do not.
What I need is a third column that says "this node has a data node below recursively" as shown below:
ID       | Parent |   IsData    | HasRecursiveDataChilds
A        |        |     N       |        Y
A1     |   A    |     N       |        N
A2     |   A    |     N       |        Y
    X1   |   A2   |     Y       |        Y/N (doesn't matter)
B        |        |     N       |        Y
B1     |   B    |     N       |        Y
    X2   |   B1   |     Y       |        Y/N (doesn't matter)
B2     |   B    |     N       |        N
C        |        |     N       |        N
C1     |   C    |     N       |        N I currently do this on the client side, after I got all the data, which involves interating through the complete dataset at least once (if you know the data well). Since the data has to be accessed from another (web) app, I want to move the logic to the server.
I'm wondering if this can be done with a simple SQL statement without using PL/SQL to iterate through the result set "manually". I can use the 10g feature set. Performance is not utterly important, so wild sub-sub-subqueries would be ok.
Thanks for your help,
Marcus

Ok, this is a bit of a fudge..

Recursive Sub-query Factoring vs Hierarchical Query

Experts,
The below are two queries i am executing by using classical approach hierarchical and newest recursive sub-query.Problem is output was different for recursive sub-query factoring, as this is not showing parent-child approach, while connect by prior is showing parent-child fashion.Query 1, i am using hierarchical as it showing correct output parent-child approach, while Query 2 is displaying all the level 1 nodes and then level 2 nodes.I want query 2 output to be same as query 1.Please modify query 2 as required.
Note:The output of the both queries won't be in displayed as it was in sqlplus, or toad.Please copy and use in your command prompts.

Hi,
What's wrong with Query 1? If it's producing the results you want, then why not use it?
One of the nice features of CONNECT BY is that the output is automatically presented in hierachical order. The only way I know of to get the results of a recursive WITH clause in any kind or order is to do it yourself. Here's one way:
WITH       secmain (id, name, mgrid, hierlevel, path)     AS
     SELECT id
     ,     name
     ,     mgrid
     ,     1               AS hierlevel
     ,     RPAD (name, 10)          AS path          -- Assuming name is never longer than 10
     FROM      main
     WHERE      mgrid     IS NULL
    UNION ALL
         SELECT     m.id
     ,     m.name
     ,     m.mgrid
     ,     sm.hierlevel + 1
     ,     sm.path || RPAD (name, 10)
     FROM     main      m
     JOIN     secmain sm ON   (m.mgrid     = sm.id)
     CYCLE     id     -- Why do you need this if CONNECT BY NOCYCLE wasn't needed in Query 1?
     SET      is_cycle     TO 1
     DEFAULT 0
SELECT        lpad ( ' '
            , 2 * (hierlevel - 1)
            ) || name                 AS name
,       hierlevel
FROM        secmain
ORDER BY path

Designing LOV Query Problem

Hello APEX people,
I posted my problem here:
Designing LOV Query Problem
What I have is a sequence like this:
CREATE SEQUENCE
DR_SEQ_FIRST_SCHEDULE_GROUP
MINVALUE 1 MAXVALUE 7 INCREMENT BY 1 START WITH 1
CACHE 6 ORDER CYCLE ;
What I need would be a SQL query returning all possible values oft my sequence like:
1
2
3
4
5
6
7
I want to use it as a source for a LOV...
The reason why I use the cycling sequence is: My app uses it to cycle scheduling priorities every month to groups identified by this number (1-7).
In the Admin Form, I want to restrict the assignment in a user friendly way - a LOV.
Thanks
Johann

Here ist the solution (posted by michales in the PL/SQL forum):
SQL> CREATE SEQUENCE
dr_seq_first_schedule_group
MINVALUE 1 MAXVALUE 7 INCREMENT BY 1 START WITH 1
CACHE 6 ORDER CYCLE
Sequence created.
SQL> SELECT LEVEL sn

Recursive Sub-query Factoring... bug? or my own personal ignorance?

I was trying to create a list of all dates in the current month using a recursive sub-query factor. (Oracle 11.2)
I know how to do this by other methods; the question is, what's going on with this "WITH" example?
Here's my attempt at generating the list:
with
date_list ( crnt_mnth_date ) as
    ( select cast ( trunc(sysdate,'MM') as date ) from dual
      UNION ALL
      select crnt_mnth_date + interval '1' day
        from date_list
       where to_char(crnt_mnth_date,'MM') = to_char(sysdate,'MM')
select * from date_list ;The recursion should add one day to the previous date and continue while the generated dates are in the same month
as the current-date (sysdate). All I get is the first day of the month. In an attempt to figure this out I added the
sequence "n". To my surprise the recursion is subtracting instead of adding the one day each time.
with
date_list ( n, crnt_mnth_date ) as
    ( select 1, cast ( trunc(sysdate,'MM') as date ) from dual
      UNION ALL
      select n+1, crnt_mnth_date + (interval '1' day) as crnt_mnth_date
        from date_list
       where n < 9
select * from date_list ;And... Changing the "+" to a "-" still subtracts one day each time -- no change.
Obvious BUG? Or am I just confused on how this works?

Hi,
I've heard that the new recursive WITH clause feature is buggy, especially when DATEs are involved.
I get the same (unexpected) results that you do.
A very similar query, using only NUMBERs, does wotk as expected:
with
date_list ( n, crnt_mnth_num ) as
    ( select 1, 20010501   from dual
      UNION ALL
      select n+1, crnt_mnth_num + 1 as crnt_mnth_num
        from date_list
       where n < 9
select * from date_list ;Outptu:
`       N CRNT_MNTH_NUM
        1      20010501
        2      20010502
        3      20010503

Recursive sql-query?

got a question about doing a recursive sql-query:
i've table containing the employee's number pnr and the superior's number vnr, who's also an employee.
my task is to get all numbers of the direct and indirect superior of a certain employee(e.g. pnr=123), meaning the result set should contain the superior's number, the superior's superior's number etc. until the superior's number is NULL.
is it possible to do that in a simple sql query?
starting:
select vnr
from staff
where pnr = 123
i don't want to write a loop using java and jdbc.
thanks in advance.

Is it possible to implement Recursive CTE query in MDX to Cube dataset?

I have data with hierarchical relationship like this:
Release -> Features -> PBI/Bugs -> Tasks/Test Case. I have two datasets Work Item and Work Item Linked to get this hierarchical information.
The data looks like this:
Something like if I pass a Release ID, I need to get all the children and sub-children also. Basically a report like this:
I did this by implementing a recursive CTE query with warehouse tables. But it takes more time to load. SO trying to find the possibility using MDX and querying the cube datasets

Hello,
There is nothing stopping you from querying the cache to see what is in it. However, this will only take into account items that are already in the cache. If you need a query to return items that are potentially not in the cache, you need to query the database, have the query return keys, and then request those keys through Coherence - which will in turn pull the items from the database as needed.

Recursive/Hierarchical Query

Hello,
I am trying to solve a problem that needs the use of recursive queries (more precisely the "connect by" clause). I have the following P table:
P1 P2
a1 a2
a1 a3
a2 a4
a3 a5
a4 a6
The result of my query should be:
P1 P2
a1 a2
a1 a3
a1 a4
a1 a5
a1 a6
a2 a4
a2 a6
As you can see, I am trying to get all the children, grandchildren, etc of every P1, going to the deepest level possible, following the transitivity property (if a1-a2, and a2-a4, then "a1 a4" will be part of the solution). The following query
select distinct P1, P2 from P
connect by P2 = prior P1
order by P1
gives me only the first level of inclusions (a1 a2, a1 a3, a2...), but I need all of them. How can I solve the problem?
Thank you!

In a 10g environment you can use the CONNECT_BY_ROOT operatory to get the root node:
WITH P AS (SELECT 'a1' P1,'a2' P2 FROM DUAL
   UNION ALL SELECT 'a1', 'a3' FROM DUAL
   UNION ALL SELECT 'a2', 'a4' FROM DUAL
   UNION ALL SELECT 'a3', 'a5' FROM DUAL
   UNION ALL SELECT 'a4', 'a6' FROM DUAL
SELECT DISTINCT CONNECT_BY_ROOT P1 P1, P2
FROM P CONNECT BY P1 = PRIOR P2
ORDER BY P1,P2
P1 P2
a1 a2
a1 a3
a1 a4
a1 a5
a1 a6
a2 a4
a2 a6
a3 a5
a4 a6

Reg: Query Problem for New Posting Period

Hi Xperts,
While I try to Map the A/P Invoices with their respective Outgoing Payment,
I used the following Query and it's Query Printlayout
SELECT T0.DocNum [Payment#], T0.DocDate [Payment Date],
T0.CardCode, T0.CardName, T1.InvoiceId, T2.DocNum [AP Inv#],
T2.NumatCard [Bill No.], T2.DocDate [Bill Date], T1.selfInv,
T1.SumApplied, T1.WtAppld, T0.NoDocsum
FROM [dbo].[OVPM] T0 INNER JOIN
[dbo].[VPM2] T1 ON T1.[DocNum] = T0.DocNum
INNER JOIN [dbo].[OPCH] T2 ON T2.[DocEntry] = T1.DocEntry
WHERE T0.Cardname='[%0]' and T0.DocDate='[%1]' and
T0.DocNum='[%2]'
I got the above query from our Expert Mr.Sambath only.
Now what is the problem is the query is retrieving the payment details of old Posting Period only and not the current posting period.
In detail, I used 'Primary' Series for FY08-09, Period indicator 'Default'
Now I'm using 'Primary1' Series for FY09-10, Period indicator '0910'
Thanx in adv.
Regards,
Bala

Hi Bala,
Looking at your query, it is not query issue ,it is your data issue.
Please check if you have data in VPM2 table which is bank transfer payment method
Thank you

VIEW Query Problem

Hi Greg,
I had created a view on a table which doesn't have Primary Key, but it has Unique and Not Null constraints on required columns.
I had wrote a procedure to query the data on VIEW. I have experienced strange problem, very first call to procedure will take more time than succeeding requests. For example from second request onwards, it returns data in < 2 Sec, but first transaction is taking 12 Sec to 30 Sec.
I thought that very first time VIEW is taking time to refresh it self. So, I added FORCE keyword in CREATE VIEW stattement. However, that doesn't helped out.
In my further investigation I came to know that base table on which VIEW created, has to be loaded in to memory before querying on VIEW.
So, I had executed a simple select statement on base table, before I execute VIEW query in procedure.
With this change I got results consistently < 2 Sec all the times.
My question is instead of executing the select statement on base table is there a way to load base tables data in memory before querying on VIEW?
Thanks,
Subbarao

Hi,
A view is nothing but parsed SQL statements stored in the database, a view may or may not run faster. If you execute the SQL used to define the view how much time is it taking. If you want try looking at MATERIALIZED VIEW , that may help you.
thanks

Date range query problem in report

Hi all,
I have created a report based on query and i want to put date range selection but query giving problem.
If i am creating select list selection then it is working fine means it will display all records on the particular date.
But what i need is that user will enter date range as creation_date1,creation_date2 and query should return all the records between these date range. i want to pass it by creating items, i created two items and passing creation_date range to display all records but not displaying and if not passing date then should take null as default and display all records

Hi User....
Here is some date range SQL that my teams uses with some success:
For date columns that do not contain NULL values, try this (note the TRUNC, it might help with your "today" problem).
The hard coded dates allow users to leave the FROM and TO dates blank and still get sensible results (ie a blank TO date field asks for all dates in the future.
AND TRUNC(DATE_IN_DATABASE)
BETWEEN
decode( :P1_DATE_FROM,
TO_DATE('01-JAN-1900'),
:P1_DATE_FROM)
AND
decode( :P1_DATE_TO,
TO_DATE('31-DEC-3000'),:
:P1_DATE_TO)
For date columns that contain NULL values, try this (a little bit trickier):
AND nvl(TRUNC(DATE_IN_DATABASE),
decode( :P1_DATE_FROM,
decode( :P1_DATE_TO,
TO_DATE('30-DEC-3000'),
NULL),
NULL)
BETWEEN
decode( :P1_DATE_FROM,
TO_DATE('01-JAN-1900'),
:P1_DATE_FROM)
AND
decode( :P1_DATE_TO,
TO_DATE('31-DEC-3000'),
:P1_DATE_TO)
Note the 30-DEC-3000 versus 31-DEC-3000. This trick returns the NULL dates when the FROM and TO date range items are both blank.
I hope this helps.
By the way, does anyone have a better way of doing this? The requirement is given a date column in a database and a FROM and a TO date item on a page,
find all of the dates in the database between the FROM and TO dates. If the FROM date is blank, assume the user want all dates in the past (excluding NULL dates). If the TO date is blank, assume that the user wants all of the dates in the future (excluding NULL dates). If both FROM and TO dates are blank, return all of the dates in the databse (including NULL dates).
Cheers,
Patrick

Multiprovider Query Problem

Hi Gurus,
The scenario is that there are 2 inficubes, one with order data and other with delivery data. The cube with order data has the requested delivery date and the delivery cube has the actual delivery date. The problem is that I have a query on a multiprovider (on top of the 2 cubes). So when I output the query data by the sales order number, the result is fine, but when I drill down on any of the dates mentioned above ( they are free characteristics in the query), the result splits up into 2 records. For Eg.
Sales Order     Req Del Date Act Del Date Order Qty Shipped Qty
12345               03/03/08         -                    5                 -
                               -           06/03/08            -                5
What can I do to get the result in one row?
I will reward points for any help.
Thanks

This is the behavior of the multiprovider, since the actual goods issue date is not part of the orders cube, then it will create a second record. There are a couple solutions you could get around to this:
1. You could merge the data in one DSO before you actually load it to the data target. To do this, you could update fields you need to the orders ods from the delivery ods.
2. You could create an infoset between the two cubes if you are in 7.0, otherwise, you could create infoset using the underlying ods and create a query from the infoset: performance wise this is not recommended.
3. If you want to solve the issue report level, there is what is called constant selection and you can make the actual goods issue date as a constant selection and you can get one line.
/people/prakash.darji/blog/2006/09/19/the-hidden-secret-of-constant-selection
I would recommend the last option,
thanks.

Out standing MIS Report query problem.

Hi,
We designed MIS Report for outstanding mis through Crystal report.here we are facing probleme.ex:AR invoice raised on 01 Jan 09 bill amount 1000 and for this client is received full amount against that bill on 04 march09.in this report we provided parameters for from date and to date. When user selected in parameter from date 010109 to 050309 it will show pending amount is 0.but users are asking if they select from date upto 030309 means it will show pending amount should be show 1000.in this query we are retrieving based on document status when open. How we can show report for this requirements. Please guide me.if we give docstatus='O' or docstatus= 'C' it's showing but pending amount =Bill amount - paid amount here it's showing 0 i think here also we need to pass incoming payment docdate.how wen do please guide me.
below this is the query.

Query problem with accumulated key figures

Hi BI Gurus!
I have a report problem that I hope you can help me with!
In my report I have 2 key figures. One for accumulated revenue previous year (KF1) and one for accumulated revenue current year (KF2). Both key figures should be presented in a graph in monthly buckets.
January figures from both the key figures shoule be presented in the same bucket. Therfore I can't use 0CALYEAR since we have the "year" information in there. Instead I'm using 0CALMONTH2 which is only two digits, 01 for January. That way I can map figures from both previous year and current year in the same bucket.
I need the figures to be accumulated and this is what I have problem with. When I run the report today in February 2010 it looks like this:
Month   KF1   KF2
01        10     15
02        10     20
03        15
04        10
05        20
06        10
07        10
08        15
09        15
10        20
11        20
12        10
This is how I would like the report to look like:
Month   KF1   KF2
01        10     15
02        20     35
03        35
04        45
05        65
06        75
07        85
08        100
09        115
10        135
11        155
12        165
I have tried to use the setting "accumulated" for the key figures but then I get this result:
Month   KF1   KF2
01        10     15
02        20     35
03        35     35
04        45     35
05        65     35
06        75     35
07        85     35
08        100   35
09        115   35
10        135   35
11        155   35
12        165   35
Since the KF2 is revenue for current year and I run the report in February I don't want any figures to be displayed in Mars...
I have tried to restrict the key figures by 0CALMONTH2 and 0CALYEAR. The KF1 is havein a restriction to only show values for 0CALYEAR - 1 and an interval for 0CALMONTH2 from JAN - DEC.
The KF2 is having a restriction to only show values in the interval "first month in year - current month" (in this example JAN - FEB) for 0CALMONTH2. And current year for 0CALYEAR.
Despite my restrictions for KF2 the numpers repeats itself for every month...
Any suggestion how I can resolve this?
Best regards
Anders Florin

Hi Khaled and thank you for trying to help me!
I agree with you and think the users should accept the report as it is. But they are claiming that top management will not accept this and they would really want this to be fixed the whay that they want. I have tried to push back on this and said that I'm not sure that it can be resoleved and that it could cost them a lot of money if I try.
But I will try to resolve it for them if I have spare time in the end of the project. I have not promised them anything but it would really be nice if I could fix it.
So when you say I need to use a structure and a calculated key figure. How should the calculated key figure and the structure be configured?
If I use a structure in the rows I guess I can't use same object in calc.key.figure right? Like if I use 0CALMONTH2 in the structure I'm not able to restrict the key figure with the same object? If that is correct I also have a ZMONTH object, different story why I have that... , that I can use in the same way as 0CALMONTH2. Or is this only a problem when I use "local" formulas within the query and not using a "global" calculated key figure? Cause I have only used the "loacal" formula calculated key figure in this report....

Abap select query problem

This report will take delivery document number and delivery date from user and fetches details from delivery table and fetches
corresponding sales order details and billing details and displays sales order details with ALV list.
<< Please only post the relevant portions of your code >>
i just want to know that is this way of fetching the data into internal table okay ?are there any better ways of fetching the data into the internal table ? why is it looping in work area of lips, why not in likp?
(plz dont use field-symbols or oo abap or macros) I WANT TO USE PLAIN AND SIMPLE ABAP STATEMENTS LIKE ABOVE..
By using "vbeln type lips-vbeln" are we refering to the field or data element? plz suggest.
P.S.           [my approach was to inner join likp and lips into itab(my internal table).
select data from kna1, vbak,vbap,vbrp into respective internal tables like it_kna1,it_vbak etc.
then using individual loops into the tables, i would use read table to insert data into itab(my final internal table) plz suggest which method wud be more efficient? ]
Edited by: Rob Burbank on Jun 8, 2009 11:54 AM

ok i am posting the select queries once again.
i want to know why are we looping in t_lips and why not t_likp? bcoz tlikp is the header table, if we loop thru it and then read the rest tables then what will be the problem? plz clarify with examples._
[my idea was to loop at t_likp then read t_lips.append the lips data into t_order(main internal table).then do read table on t_kna1,t_vbap etc indexing t_order. so plz suggest whether my approach was write or wrong?if wrong why?plz site any other ways of doing this query.
types: begin of ty_vbap,
       vbeln type vbap-vbeln,
       posnr type vbap-posnr, .....
does the declaration statement in types refer to tables or data elements? what is the difference if we declare it like:
