Oracle Discoverer sub query in join

I wonder if anyone can help me?
I've got two tables (table a and b) that have a number of joins.
I need to add another join between table a and b where a date field (from table a) equals the maximum value for this date field (where the above joins hold).
How do I add this as a join in Oracle Discoverer Administrator?
Basically, how do you add a subquery in a join?
Thanks.

Correlated sub-query/outer join problem

Hi,
I have a problem similar to this one (Outer join with correlated subquery but I'm struggling to find a solution for mine!
The following query works OK unless there is no entry in room_prices, so I need to outer join somehow to that table otherwise it doesn't return any rows.
The main difference between the query in the other thread and mine is that mine has an extra table (bookings b) in the sub-query, which is complicating things a bit.
select b.book_from,
     b.book_to,
     b.flat_rate,
     nvl(c.discount,0),
     p.hourly,
     p.half_day,
     p.daily,
     p.discountable,
     p.surcharge,
     l.evening_start,
     nvl(b.full_day,'N')
from booking.bookings b,
booking.customer c,
booking.room_prices p,
booking.rooms r,
booking.location l
where b.id = 9272
and c.id = b.customer
and b.room = p.room
and b.room = r.id
and r.loc = l.id
and p.from_date =
select max(p2.from_date)
from booking.room_prices p2
where p2.room = p.room
and p2.from_date < b.book_from
Could anyone suggest a way to re-write the query so that it is outer joined to room_prices?
Thanks,
Hazel

Oracle Discoverer 4 query

Hi All,
I need to create a report in Oracle Discoverer. I would like to know if it is possible to create a report with the following logic. If yes, then how do I go about creating a report.
I have a table TBLREPORT with the following structure from which I have to pick up records.
Table: TBLREPORT
dttime DATE
interval VARCHAR2(10) (The field will have values BASE, HOURLY)
rdvalue number (aggregate to be applied in business area is AVG)
Data in table:
Dttime interval rdvalue
20-AUG-2001 9:00 am HOURLY 10
20-AUG-2001 10:00 am HOURLY 20
21-AUG-2001 9:00 am HOURLY 20
21-AUG-2001 10:00 am HOURLY 30
22-AUG-2001 9:00 am HOURLY 10
22-AUG-2001 10:00 am HOURLY 20
23-AUG-2001 9:00 am BASE 10
23-AUG-2001 9:15 am BASE 20
23-AUG-2001 9:30 am BASE 30
23-AUG-2001 9:45 am BASE 40
23-AUG-2001 9:00 am HOURLY 25 (the base data for 23-AUG-2001 from 9:00 am to 9:45 am is rolled up to arrive at HOURLY data e.g. 10+20+30+40 = 100/4 = 25)
23-AUG-2001 10:00 am BASE 50
23-AUG-2001 10:15 am BASE 60
23-AUG-2001 10:30 am BASE 70
23-AUG-2001 10:45 am BASE 80
23-AUG-2001 10:00 am HOURLY 65 (the base data for 23-AUG-2001 from 10:00 am to 10:45 am is rolled up to arrive at HOURLY data e.g. 50+60+70+80 = 260/4 = 65)
24-AUG-2001 9:00 am BASE 10
24-AUG-2001 9:15 am BASE 20
24-AUG-2001 9:30 am BASE 30
24-AUG-2001 9:45 am BASE 40
24-AUG-2001 9:00 am HOURLY 25 (the base data for 24-AUG-2001 from 9:00 am to 9:45 am is rolled up to arrive at HOURLY data e.g. 10+20+30+40 = 100/4 = 25)
24-AUG-2001 10:00 am BASE 50
24-AUG-2001 10:15 am BASE 60
24-AUG-2001 10:30 am BASE 70
24-AUG-2001 10:45 am BASE 80
24-AUG-2001 10:00 am HOURLY 65 (the base data for 24-AUG-2001 from 10:00 am to 10:45 am is rolled up to arrive at HOURLY data e.g. 50+60+70+80 = 260/4 = 65)
From this table I have to pick-up data for week = 20-AUG-2001 to 24-AUG-2001.
(the week start date is entered by the user in the report)
I have to first check if BASE data exists for the week.
If no base data exists then check for HOURLY data.
The following data exists:
No BASE data will be available for 20-AUG-201, 21-AUG-2001 or 22-AUG-2001, since it would have been deleted. HOURLY data is available for these days.
BASE data would be available for 23-AUG-2001 and 24-AUG-2001. HOURLY is available for these days also.
20-AUG-2001 21-AUG-2001 22-AUG-2001 23-AUG-2001 24-AUG-2001
No BASE No BASE No BASE BASE BASE
HOURLY HOURLY HOURLY HOURLY HOURLY
The input to the report is:
Week start date = 20-aug-2001
Hour range = 9:00 am to 10:00 am
Now in order to produce a weekly report,
1) The HOURLY data for 20-AUG-201, 21-AUG-2001 and 22-AUG-2001 should be viewed for the hour ranges the user enters.
2) The BASE data for 23-AUG-2001 and 24-AUG-2001 should be rolled-up to arrive at HOURLY data only for the hour ranges entered by the user, using the logic specified for rollup as given in the data. The HOURLY data present for 23-AUG-2001 and 24-AUG-2001 should not be considered but the BASE data should be considered which should be rolled-up to arrive at HOURLY data.
3) Then the HOURLY data from 20-AUG-201, 21-AUG-2001, 22-AUG-2001, Base data of 23-AUG-2001 and 24-AUG-2001 rolled-up to HOURLY should be used to generate the weekly report, taking into consideration the hour ranges entered by the user.
Any help will be greatly appreciated.
Thanks in advance

Hi,
When users are removed from the system their privileges in EUL4_ACCESS_PRIVS are not removed. However, when the privileges are exported and imported only the privileges of valid users are imported into the EUL. Therefore it could be that the missing privileges relate to users that are no longer on the system. You would have to check in the original EUL4_ACCESS_PRIVS to confirm that.

Oracle Discoverer Plus - sub query

Hi,
Quick question do you know if the sub query is available in Disco Plus yet?
If so which version and/or what configuration is required.
I know you can still do this in the desktop and then run it in plus but this means users can't do it.
Regards,
Paul.

Thanks for this I know it can't be done in the current version. I was hoping that it was something being addressed.
Its a pain to be able to do it in the desktop client and not the web version.
Its a work around when links are not present to the folders.
Cheers,
Paul

Hi! Everyone, I have some problems with JOIN and Sub-query; Could you help me, Please?

Dear Sir/Madam
I'm a student who is interested in Oracle Database and
I have some problems with JOIN and Sub-query.
I hope so many of you could help me.
if i use JOIN without sub-query, may it be faster or not?
SELECT field1, field2 FROM tableA INNER JOIN tableB
if i use JOIN with sub-query, may it be faster or not?
SELECT field1,field2,field3 FROM tableA INNER JOIN (SELECT field1,field2 FROM tableB)
Thanks in advance!

As the others have said, the execution plan will give you a better idea about which is faster.
If you're trying to see how using (or not using) a sub-query affects performance, make the rest of the queries as similar as possible. For example, include field3 in both queries, or ignore field3 in both queries.
In this particular case, I guess the optimizer would do the same thing either way, but that's just a guess. I can't see your execution plans.
In general, simpler code is faster, and better in other ways, too. In this case
tableB
is simpler than
(SELECT field1, field2 FROM tableB)
Why do you want a sub-query in this example?

Outter-Join with requirement for sub-query

I am working on a view that needs to return 1 record per payment date within the primary payment table.
Part of the information that is to be returned in this row comes from a date-controlled table containing superannuation information. This data may or may not be present, requiring an outer-join. The final problem is that there may be multiple rows in this superannuation table requiring me to retrieve the record with the most recent start date, prior to the payment date. This is where I'm breaking down currently as I cannot outer-join to a sub-query.
I had an idea that I could create an inline view of the superannuation table with 1 row for each of the last 365 days (The reports that will be built off the view are always run within 1-2 months of the payment date), with the date and either the required information or blanks if it did not exist. This would avoid me requiring an outer-join as I could just join on the payment date to the date in the inline query and return whatever data was there.
I'm pretty sure I should be able to do this with analytics rather than creating a date table, by restricting the rows to 365, then havign a column that is effectively the previous column - 1. Unfortunately I'm fairly new to analytics and find the Oracle documentation hard to decipher.
Can anyone help with this or perhaps suggest an alternate solution?

please don't do that. that's the most pathetic way generate rows. all_objects is a very nasty view, and oracle reserves the right to merge the view into the rest of your query, making performance less than you had hoped for. how about this instead:
select ...
from (
select trunc(sysdate-rownum+1) super_date
from dual
connect by level < = 365 ) dates,
your_table_here
where dates.super_date = your_column (+)
...

Sub-query problem on Oracle 10g

The following query works on Oracle 10.2.0.1.0 on windows,but doesn't work on Oracle 10.2.0.2.0 on Linux.
Error report: SQL Error: ORA-00904: "T"."AUDIT_USECS": invalid identifier 00904. 00000 - "%s: invalid identifier"
It works after i remove the sub-query. I found that if use fields of T in sub-query,then error occurs. Is it saying that sub-query can't access the fields in main query?
What's the problem?
Is there any grammar erros?If so,what's the right likes?
Thanks!

Joining with sub query not working

Hi
I am new with these complex queries. I am trying to join a sub query to a query as below;
SELECT Events1.InvoiceBatch AS BatchNo, Events1.InvoiceBatchDate AS BatchDate, tblClients.Company, tblClients.ID AS ClientID, COUNT(Events1.ID) AS Invoices,
COUNT(*) - COUNT(Events1.InvoicePrintDate) AS E, Events1.InvoiceBatchFromDate AS BatchFrom, Events1.InvoiceBatchToDate AS BatchTo, (SELECT EventID, SUM(Total) FROM tblStaffBookings AS StaffBookings WHERE StaffBookings.EventID = Events1.ID GROUP BY EventID) AS Total
FROM tblEvents AS Events1 LEFT OUTER JOIN
tblClients ON Events1.ClientID = tblClients.ID
WHERE (Events1.FactoringExportDate IS NULL) OR (Events1.AccountsExportDate IS NULL) OR (Events1.InvoiceSentDate IS NULL)
GROUP BY Events1.InvoiceBatch, Events1.InvoiceBatchDate, tblClients.Company, tblClients.ID, Events1.InvoiceBatchFromDate, Events1.InvoiceBatchToDate
HAVING (Events1.InvoiceBatch = 5212)
ORDER BY tblClients.Company
I am getting these two errors;
Msg 8120, Level 16, State 1, Line 2
Column 'tblEvents.ID' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
Msg 116, Level 16, State 1, Line 2
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
What am I missing?
Thanks

Best way to outer join a table that is doing a sub query

RDBMS : 11.1.0.7.0
Hello,
What is the best way to outer join a table that is doing a sub query? This is a common scenario in EBS for the date tracked tables.
SELECT papf.full_name, fu.description
FROM fnd_user fu
      ,per_all_people_f papf
WHERE fu.user_id = 1772
   AND fu.employee_id = papf.person_id(+)
   AND papf.effective_start_date = (SELECT MAX( per1.effective_start_date )

I think RANK suits the requirements better than ROW_NUMBER:
WITH    all_matches     AS
     SELECT papf.full_name
     ,      fu.description
     ,     RANK () OVER ( PARTITION BY papf.person_id
                           ORDER BY          papf.effective_start_date     DESC
                    )           AS r_num
     FROM             fnd_user             fu
     LEFT OUTER JOIN      per_all_people_f papf ON fu.employee_id = papf.person_id
     WHERE   fu.user_id = 1772
SELECT     full_name
,     description
FROM     all_matches
WHERE     r_num     = 1
Johnnie: I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.

Issue with join condition while using in the corelated sub query

Bees,
I am not able to use the below query since i have used a join condition in the corelated sub qery inline view.But i have a requirement like this . Please help me on this
select * from dept d
where exists (select 1 from (
select deptno
from emp where deptno= d.deptno)
Thank you
Boooo

Hi,
I've never seen a general solution for how to reference columns from main query a from sub-query c, where c is is sub-query of b, which is a sub-query of a.
Whenever I've wanted to, I've been able to get the desired results with a different approach.
In this case, you seem to want
SELECT     *
FROM     dept     d
WHERE     EXISTS     (
          SELECT     1
          FROM     emp
          WHERE     deptno     = d.deptno
          );I'm guessing at your data and desired output.

Oracle Discoverer Plus - Don't run query automatically

I have, in the Options tab in Oracle Discoverer Plus, a check mark next to not run a query automatically. This is not working when I have several worksheets in my report. After I run one worksheet and click on the next (tab) worksheet it automatically runs that report with the old parameter values thereby providing ambiguous results.

Hi,
Try editing the parameter and selecting "Allow a different value in each sheet".

Can i join a list in sub-site using Join query?

Hi all,
I'm newbie and i have tried to join a list in parent site with a list in sub-site using Join query but i always get the error. How can i do this action? Thanks!

You could try using SPSiteDataQuery or a DataTable.

Correlation in Oracle Discoverer

Hi,
I know how to calculate correlation in Oracle discoverer plus using calculations but is there a way for us to give the users the ability to drag drop the variable they want to see the correlation between in viewer. So for example if the user wanted to see the correlation between SAT scores and age they could just select the variables somehow and see the correlation between them.
Thanks

There is no straight forward way but one possible solution:
1.
Create a folder in the eul that contains two columns
1) a dummy column
2) a LOV column
I usually do this with a query SELECT 'dummy' as joiner, 'LOV ITEM' as lov_item from dual union....;
2.
create a LOV on the LOV Item column
3.
create a join between the new table and another table in the workbook
4.
create 2 parameters based on the lov item column (do not create a condition with the parameter)
5. create a calculation that calculation that well correlate two items based on the values of the parameters
6. remove the new table from the workbook. The new table will not affect how many rows are returned but the parameters still look at the LOV table.

Oracle date parameter query not working?

http://stackoverflow.com/questions/14539489/oracle-date-parameter-query-not-working
Trying to run the below query, but always fails even though the parameter values matches. I'm thinking there is a precision issue for :xRowVersion_prev parameter. I want too keep as much precision as possible.
Delete
from CONCURRENCYTESTITEMS
where ITEMID = :xItemId
and ROWVERSION = :xRowVersion_prev
The Oracle Rowversion is a TimestampLTZ and so is the oracle parameter type.
The same code & query works in Sql Server, but not Oracle.
