Query with multiple outer joins
I had a doubt with whether the following kind of query is valid with multiple outer-joins. The format of the query is something like this:-
select A.col1, B.col2
from table1 A, table2 B, table3 C where
A.col3=B.col4(+) and B.col5=C.col6(+)
This would mean the follwoing with regard to outer-joins in the query.
1) fetch records with col3 in table A matching or not matching col4 in table B
2) fetch records with col5 in table B matching or not matching col6 in table C
So, this query is valid?
I hope, my question is clear.
Please, help in solving the doubt.
regards
This is valid and it works fine

Query with FULL OUTER JOIN , help pleaseeeeeeeeeeee...
Hi everyone,
I'm trying to write a query for a report in Oracle SQL, but i just can't figure out how to do it.
I'm using Oracle 10g release 1.0 database and i execute my queris in SQL* PLUS ( eventually i'm gonna use them in Oracle Report Builder ) .
here's what i have:
i have four tables that are used for our inventory application. lets call them INCOMMING , INCOMMING_ITEMS , OUTGOING , OUTGOING_ITEMS.
as you may have guessed , INCOMMING_ITEMS is the detail table for INCOMMING ( joined by IID column) and also OUTGOING_ITEMS is the detail table for OUTGOING ( joined by OID column ).
here is the structure of them :
INCOMMING
IID varchar2
CDATE date
INCOMMING_ITEM
IID varchar2
PART_NO number
QTY number
OUTGOING
OID varchar2
CDATE date
OUTGOING_ITEM
OID varchar2
PART_NO number
QTY number
now , the query i want, should return part_no , cdate , sum of OUTGOING qty , sum of INCOMMING qty .
the result of the query should be sth like this :
part_no cdate O_qty I_qty
100 01/05/06 10 0
100 01/05/07 20 60
200 01/06/02 0 50
300 01/06/02 30 40
this means that for some dates and for some parts, i may not have INCOMMING or OUTGOING data, but if at least one of the 2 last columns has a non-zero data, i should show the row ( like the first and third rows of my example result), and if both have data for the same PART_NO and the same CDATE, both should be showed in the same row. ( like the second row in my example result)
i tried so much and came up with several huge and also time consuming queries, but then i read abt FULL OUTER JOIN somewhere and tried using that. here is what i came up with :
SELECT
PART_NO , CDATE , sum(II.QTY) I_QTY , SUM (OI.QTY) O_QTY
FROM
(OUTGOING O INNER JOIN OUTGOING_ITEM OI USING ( OID ) )
FULL OUTER JOIN
(INCOMMING I INNER JOIN INCOMMING_ITEM II USING ( IID ) )
ON ( I.CDATE = O.CDATE AND II.PART_NO = OI.PART_NO)
WHERE
I.CDATE = :PARAMETER1
AND O.CDATE = :PARAMETER1
GROUP BY
PART_NO , CDATE
this query is short and fast , but the results r not what i expected. i mean, although i have used FULL OUTER JOIN in the query , but the results i get r sth like this :
part_no cdate O_qty I_qty
100 01/05/07 20 60
300 01/06/02 30 40
which means only the rows that has both values are returned.
any change i make to this query would make the SQL* PLUS hang , like when i use the cartesian product of two large tables, so i guess my changes wheren't in the right direction.
i think its possible to write this query using FULL OUTER JOIN syntax, but i just can't find it.
Can anybody pleaseeeeeeeeeeeee help me?
thanx in advance,
Maryam.Note: I wrote this on the fly -- hope there is no syntax errors, otherwise forgive me -- but you get the idea..
select
fromUnionAll.cdate, fromUnionAll.part_no,
sum(fromUnionAll.O_qty) O_qty,
sum(fromUnionAll.I_qty) I_qty

from
select
i.cdate, ii.part_no,

no record anywhere for the given CDATE in INCOMMING_item */
sum( ( case when ii.qty is not null then ii.qty else 0 end) ) I_qty
from

where
i.iid = ii.iid (+)

Query of query with left outer join
Hi,
I cannot use joins in query of query, I try the old method using the ( + ) but no luck "Query Of Queries syntax error. Encountered ( + )."
Here is an example of my query code:
select p.part_id, s.supplier_name, s.second_name
from part p, supplier s
where p.supplier_id = s.supplier_id ( + )
and p.second_id = s.second_id ( + );
PART SUPPLIER_NAME SECOND_NAME
P1 Supplier#1 A
P2 Supplier#2
P3
P4
How can I do the same in query of query syntax?
Thanks!I found a solution:
http://www.bealearts.co.uk/blog/2007/06/20/how-to-do-an-outer-join-in-query-of-queries/
I am not sure about my second condition. i create the join query for the empty columns.
select part.part_id, supplier.supplier_name, supplier.second_name
from part, supplier
where part.supplier_id = supplier.supplier_id
and supplier.second_id is null
union
select part.part_id, supplier.supplier_name, supplier.second_name
from part, supplier
where part.supplier_id = supplier.supplier_id
and part.second_id = supplier.second_id
union
select part.part_id, joinQuery.supplier_name, joinQuery.second_name
from part, joinQuery
where part.supplier_id not in (#ValueList(supplier.supplier_id)#)
Can anyone check and let me know if this is correct?
My final result have one less row from parts table.

Select List or Radio Buttons query with multiple tables join
Hello,
I'm having a problem creating a select list or a radio group item.
I need to display the emp_first_name in the select list but have the return value of the order_id in the select list or radio buttons item.
The tables are as follow:
emp_table
emp_id
emp_first_name
emp_last_name
etc...
orders_table
order_id
order_name
emp_id
etc...
I need to display the emp_name from emp_table in the select list but return the order_id from the orders_table as the return value.
How can I do this?
Any help would be greatly appreciated.
Thanks.
Regards,
NJHi NJ,
Try:
select e.emp_first_name d,
o.order_id r
from orders_table o
inner join emp_table e on o.emp_id = e.emp_id
order by 1You may have an issue with an emp_id being used for more than one order and, therefore, the employee's name appearing more than once in the list?

BaseTableName blank when calling GetSchema on a query with multiple tables
I am using ODP.NET 11.2.0.3.0 and when calling GetSchemaTable on a DataReader that contains a join the returned SchemaTable has the BaseTableName and BaseColumnName fields blank - this is different than what I see with the Oracle OLE DB Provider and with how SQL Server's native provider works. I can't find any discussion of this - is this on purpose or is it a bug? why does the available schema information vary so drastically between a single table query and a query with multiple tables joined?
Thanks,
Bryan HintonHi Bryan,
I am also facing the same issue. Did u find any work around or any suggestions will be well appreciated.

Oracle hangs on query with multiple joins
To test the sotftware from the LMS-vendor that are out partners we use virtual machines where we install Windows 2003 servers and Oracle XE
While we were testing the software I've found that a particular query with multiple unions causes the CPU of the virtual machine totally claimed by oracle
The query causes oracle to hang.
I've found that the subcomponents of the query all return 0 rows (and response all immediately) combined into a query with at least 2 unions the query hangs the system
I'm not familiar with with Database Management at all
I've read something about SGA and PGA that could be the issue and tried to increase the target for both but it doesn't seem to do anything

Multiple Outer join in ORACLE 8.1.6
Hi ,
Can anybody suggest me how can i use multiple outer join on one table. I'm using ORACLE 8.1.6.
I know this version of oracle doesnt support this. But is there anmy other wa\y I can achieve this.
Thanks amd Regards
DeependraTricky question - but I went through this about 3 months ago, and found a good thread on here that explains it pretty well.
check out Re: Outer join a table with two diff table
You basically will have to create an inline view with one outer join in there, and then a second outer join on the outside. Read through the posts in that thread and it should help! -
How to have a condition with the outer join
Hi, I'd like to know if, inside a report, there's a way to create a condition which include in some way an outer join.
So, I have 2 custom folders:
Tickets with 2 fields: Ticket_id, Inventory_item_id, category_id and iptv_sumptom
Hierarchy with 4 fields: Symptom, Inv_item_id, Category_id and Group
These 2 folders are joined in this way
Tickets.inventory_item_id = Hierarchy.inv_item_id (+) AND Tickets.category_id = Hierarchy.category_id (+) AND Tickets.iptv_sumptom = Hierarchy.Symptom (+)
Now, from the report I have a parameter based on the field Group to restrict dataset of the tickets.
...but when I choose a group and I run the report, the conditions inside the plsql query generated is like this
WHERE (Tickets.inventory_item_id = Hierarchy.inv_item_id (+) AND Tickets.category_id = Hierarchy.category_id (+) AND Tickets.iptv_sumptom = Hierarchy.Symptom (+)) AND Hierarchy.Group = 'A'
where the last condition is WITHOUT outer join !
I need to have also the outer join on the Hierarchy.Group: AND Hierarchy.Group (+) = 'A', but from the Administrator I don't want to add another join with (+) for the Group. From Plus I didn't find any way to write (+).....
Anybody knows another method or workaround to have also a filter (the condition Hierarchy.Group = 'A') with an outer join ?
Thanks in advance
AlexHi,
A workaround can be either use new objects or modify the existing ones to avoid the outer join.
In order to do that you can add a dummy record to each custom folder and then join by it.
For example if you will add to the
Tickets will be:
select Ticket_id, Inventory_item_id, category_id, iptv_sumptom
from......
union all
select -1,-1,-1,'Some value' from dual
And hierarchy will be:
select Symptom, Inv_item_id, Category_id ,Group
from......
union all
select 'Some value',-1,-1,'Some value' from dual
Now you can create a full join between them without the need to outer join.
Hope it will help

Set READ UNCOMMITED for a query with a table join (Ver 12.5. and 15.5)
Hi all,
this is an example of how to set the READ UNCOMMITED isolation level for a simple query:
select col_a from mytable at isolation 0
What about a query with an equi-join?
Is it:
select col_a
from mytable t1, mytable t2
at isolation 0
I am sorry for the simple question, I did not find a auitable example in the documentation.
Best Regards
ArthurYeah, the docs aren't very good at providing a robust set of examples so you've gotta:
1 - review the command syntax and then
2 - try a few examples until you find the format that works
1 - From the ASE 15.5 Commands reference manual we find the following syntax:
=========================
select ::=
select [all | distinct]
[top unsigned_integer]
select_list
[into_clause]
[from_clause]
[where_clause]
[group_by_clause]
[having_clause]
[order_by_clause]
[compute_clause]
[read_only_clause]
[isolation_clause]
[browse_clause]
[plan_clause]
=========================
This shows us that the isolation clause is attached at the 'end' of the query as a query-level specifier (along with the 'group by', 'order by' and 'having' clauses).
From this syntax I'd say your proposed query looks correct so ...
2 - Try running your example to see if you get a syntax error ("When in doubt, try it out!"), eg:
=========================
select s.name,c.name
from sysobjects s, syscolumns c
where s.id = c.id
at isolation 0
go
name
sysobjects
sysobjects
sysobjects
... snip ...

Update Statement with left outer join
hi,
i have to update a column in table "a" from table "b" and both of them joined with left outer join
How can I do this
Thanks in AdvancePlease consider the following when you post a question. This would help us help you better
1. New features keep coming in every oracle version so please provide Your Oracle DB Version to get the best possible answer.
You can use the following query and do a copy past of the output.
select * from v$version 2. This forum has a very good Search Feature. Please use that before posting your question. Because for most of the questions
that are asked the answer is already there.
3. We dont know your DB structure or How your Data is. So you need to let us know. The best way would be to give some sample data like this.
I have the following table called sales
with sales
as
select 1 sales_id, 1 prod_id, 1001 inv_num, 120 qty from dual
union all
select 2 sales_id, 1 prod_id, 1002 inv_num, 25 qty from dual
select *
from sales 4. Rather than telling what you want in words its more easier when you give your expected output.
For example in the above sales table, I want to know the total quantity and number of invoice for each product.
The output should look like this
Prod_id sum_qty count_inv
1 145 2 5. When ever you get an error message post the entire error message. With the Error Number, The message and the Line number.
6. Next thing is a very important thing to remember. Please post only well formatted code. Unformatted code is very hard to read.
Your code format gets lost when you post it in the Oracle Forum. So in order to preserve it you need to
use the {noformat}{noformat} tags.
The usage of the tag is like this.
<place your code here>\
7. If you are posting a *Performance Related Question*. Please read
{thread:id=501834} and {thread:id=863295}.
Following those guide will be very helpful.
8. Please keep in mind that this is a public forum. Here No question is URGENT.
So use of words like *URGENT* or *ASAP* (As Soon As Possible) are considered to be rude. -
Doubt in Firing Query with multiple opportunities UUID/IDs
HI Folks!
I might have simple doubt but please help me on this!
1. I have a custom BO with association to opportunities.
[DeploymentUnit(CustomerRelationshipManagement)] businessobject Sy_Trade {
[AlternativeKey] [Label("Trade Id")] element tradeid : BusinessTransactionDocumentID;
node RelatedOpportunities [0,n]{
element BusinessTransactionDocumentReference : BusinessTransactionDocumentReference;
element BusinessTransactionDocumentRelationshipRoleCode : BusinessTransactionDocumentRelationshipRoleCode;
association RelatedOpportunity[0,1] to Opportunity;
2. I have success fully used association and i am able to view create all the opportunities related to my custom Bo.
ISSUE : I want a facet where i just want DISPLAY the activities and sales document assigned in the RELATED OPPORTUNITIES ( N opportunities )
How do i query with Multiple opportunities ID and fetch the activities against it?
Btw I want to use query in UI Designer... I have created an advanced list pane and there i want the result list
I hope i am clear!
Thanks in adavance...
Regards
DhruvinHi Ludger,
I have successfully displayed Related Opportunities associated with trade.( i am able to create , delete also )
Issue : I am not able to "Display" ( i don't need to edit or create ) all the activities created against all the opportunities in a different tab.
I tried to approaches :
1: Query : Created a Query on Activity BO and tried to pass multiple related opportunities ( but seems not possible , please tell me any possibility to pass range of opportunity via transformation or anything? )
2 : binding : I have a Node Related Opportunity so just tried to bind it with BO model but problem is it is displaying all the activities of first opportunity of the list...
i think why because :
In Data model I have created a table bind with Related Opportunities...
now that node is 1 to N , association to opportunity 0 to 1 , hence i think it fetches only 1 opportunities activity
should i create like below ( Or is it possible)
Node Reltdoppts[0,1]
association [0,N] to opportunity BO ?
Although i strongly feel SAP should provied us two things :
1. We need to pass range of opportunities in a query.
2. We need to just write some absl code where i can fill the table and display it
and also is there any possibility to create a report or something to display activities as we just want to display the activities!
P.S : I have been getting a lot of bashing from client because some of the product restriction in cloud! i hope and wish SAP give developers free hand to develop right now its like our hands are tied to many things -
Web service with multiple out parameters
Hi Developers,
I have been playing around with som web services in the developer studio.
I can create a webservice from a normal ejb.
But i can only get one out parameter, which is the return parameter of the ejb.
I tried to make an object to use as return parameter, but then i couldn't use the method for the web service.
Can anyone tell me how to make a web service with multiple out parameters?
Br RasmusHi Developers,
I have the same question, is it possible to have multiple outgoing parameters?
When not, does SAP Netweaver knows a IN-OUT parameter? Because I found on the internet that it is possible to have a IN-OUT parameter. But that was with the BEA Weblogic 8.x.
When not, is then the only solution to return a object? With in this object all the parameters you want.
Or otherwise is there a other workaround?
Thanks in advance,

APD using Query with multiple structures as a data source
All,
I want to set up an automatic process which executes a query and exports it to a shared drive as a csv file. I have tried various options , when I try to use APD to set up the extract, I get an error and this is because the query that I am trying to use has Strucutres in both rows and columns. Hence, I am unable to use this option. I tried RSCRM_BAPI, It works well, but there is an issue with scheduling this in Process chain. I created an event and scheduled this as a job to trigger after "event" as per SAP instructions, but the job does not exist and it is not possible to trigger it through the Process chain unless the variables are hard coded in the query which I do not want to do.
Can any one tell me if there is a way to deal with APD using Query with multiple structures?
Would really appreciate if some one can give me the right solution...
ThanksHi Tanu ,
APD is an option but its not very good with large amount of data or hiearachies or if you have attributes in you query structure .
One more option for this requirement is use of report program using function module RRW3_GET_QUERY_VIEW_DATA .
This will work fine with multiple structure etc .
There are some overheads with this FM ex: if amount of data is too much then program will give dump .Solution for that is we call the FM in LOOP by diving amount of data need to be fetched .ex: we can read data quarter wise.
For using this function module what you can do is write an ABAP program (At SE38 ) .which will call this FM and then write the output into a flat file which you can save at application server (AL11) .From there other system can read it .
To automate this whole process you can further add all the report programs into a process chain (RSPC) which can be schedule as per requirement .
To pass input parameters you can use variants that will pass the values to the report .
Check thi link for sample code :

Hope this will be helpful .

Sql query with multiple joins to same table
I have to write a query for a client to display business officers' names and title along with the business name
The table looks like this
AcctNumber
OfficerTitle
OfficerName
RecKey
90% of the businesses have exactly 4 officer records, although some have less and some have more.
There is a separate table that has the AcctNumber, BusinessName about 30 other fields that I don’t need
An individual account can have 30 or 40 records on the other table.
The client wants to display 1 record per account.
Initially I wrote a query to join the table to itself:
Select A.OfficerTtitle, A.OfficerName, B.OfficerTitle, B.OfficerName, C.OfficerTtitle, C.OfficerName, D.OfficerTitle, D.OfficerName where A.AcctNumber = B.AcctNumber and A.AcctNumber = C.AcctNumber and A.AcctNumber = D.AcctNumber
This returned tons of duplicate rows for each account ( number of records * number of records, I think)
So added
And A.RecKey > B.RecKey and B.RecKey > C. RecKey and C.RecKey . D.RecKey
This works when there are exactly 4 records per account. If there are less than 4 records on the account it skips the account and if there are more than 4 records, it returns multiple rows.
But when I try to l join this to the other table to get the business name, I get a row for every record on the other table
I tried select distinct on the other table and the query runs for ever and never returns anything
I tried outer joins and subqueries, but no luck so far. I was thinking maybe a subquery - if exists - because I don't know how many records there are on an account, but don't know how to structure that
Any suggestions would be appreciatedWelcome to the forum!

The client wants to display 1 record per account.As someone has already mentioned, you should post CREATE TABLE and INSERT statements for both tables (relevant columns only). You don't have to post a lot of sample data. For example, you need to pick 1 out of 30 or 40 rows (max) for the same account, but it's almost certainly enough if you post only 3 or 4 rows (max) for an account.
Also, post the results you want from the sample data that you post, and explain how you get those resutls from that data.
Always say which version of Oracle you're using. This sounds like a PIVOT problem, and a new SELECT .... PIVOT feature was introduced in Oracle 11.1. If you're using Oracle 11, you don't want to have to learn the old way to do pivots. On the other hand, if you have Oracle 10, a solution that uses a new feature that you don't have won't help you.
Whenever you have a question, please post CREATE TABLE and INSERT statements for some sample data, the results you want from that data, an explanation, and your Oracle version.
Initially I wrote a query to join the table to itself:
Select A.OfficerTtitle, A.OfficerName, B.OfficerTitle, B.OfficerName, C.OfficerTtitle, C.OfficerName, D.OfficerTitle, D.OfficerName where A.AcctNumber = B.AcctNumber and A.AcctNumber = C.AcctNumber and A.AcctNumber = D.AcctNumber Be careful, and post the exact code that you're running. The statement above can't be what you ran, because it doesn't have a FROM clause.
This returned tons of duplicate rows for each account ( number of records * number of records, I think)
So added
And A.RecKey > B.RecKey and B.RecKey > C. RecKey and C.RecKey . D.RecKey
This works when there are exactly 4 records per account. If there are less than 4 records on the account it skips the account and if there are more than 4 records, it returns multiple rows.

I tried outer joins and subqueries, but no luck so far. I was thinking maybe a subquery - if exists - because I don't know how many records there are on an account, but don't know how to structure that
Any suggestions would be appreciatedDisplaying 1 column from n rows as n columns on 1 row is called Pivoting . See the following link fro several ways to do pivots:
SQL and PL/SQL FAQ
Pivoting requires that you know exactly how many columns will be in the result set. If that number depends on the data in the table, then you might prefer to use String Aggregation , where the output consists of a huge string column, that contains the concatenation of the data from n rows. This big string can be formatted so that it looks like multiple columns. For different string aggregation techniques, see:
http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php
The following thread discusses some options for pivoting a variable number of columns:

Is there a way , where i can simplify the joins with tbloption and tblLabelDetail and get my o/p in optimal time.
RegardsI have headed towards another approach ie. using unpivot and then pivot.
First i am converting option1-option9 into column , then doing PIVOT to get back the same record . But issue is that when i am doing pivoting i am getting NULL values.
My query is :
select * into #t1 from
select ID
, option1
, option2
, option3
, option4
, option5
, option6
, option7
, option8
, option9
from vCustomConsumer
where sid=105
and sessionYM = 1412
) SourceTable
UNPIVOT
optionID FOR Col IN
(option1
,option2
,option3
,option4
,option5
,option6
,option7
,option8
,option9 )
) AS unpvt
select t.ID,t.optionID,t.col,cast(ld.text as varchar(max)) as text into #t2
from #t1 t
left outer join tbloption o on o.ID = t.optionID
left outer join tblLabelDetail ld on ld.labelID = o.labelID and ld.langID=1
order by ID,col
select ID,option1
,option2
,[option3]
,option4
,option5
,option6
,option7
,option8
,option9
from
select ID,optionID,col,text
from #t2
)up
pivot
min(text)for col in
(option1
,option2
,[option3]
,option4
,option5
,option6
,option7
,option8
,option9
)as pvt
In my last query where i am using pivot, i am getting NULL values. When i check the data in temp table #t2 , it exists perfectly . But when pivoting i dont understand why it is returning most of the NULL values. I am getting data for only one column in single
row.
Below are some rows from result set finally obtained after pivoting :
ID
option1
option2
option3
option4
option5
option6
option7
option8
option9
