OUTER JOINS

I am a user of Dicoverer 4.1 and I write queries from the EUL. I need help in writing my query that will return all records in Table A and matching and Null values from Table B. A simple employee roster with all Names(Table A)and all addresses(Table B)including Null addresses. Here is the exact sql statement I get from a simple query that only gives me employees who have addresses (I know there are some who don't have addresses).
SELECT POSITION_EMPLOYEE_SECV.NAME_PERS, ADDRESS_SECV.LOCAL_ADDR_CITY
FROM CSUDB.POSITION_EMPLOYEE_SECV POSITION_EMPLOYEE_SECV, CSUDB.ADDRESS_SECV ADDRESS_SECV
WHERE ( ( POSITION_EMPLOYEE_SECV.SSAN_EMPL_CON_NR = ADDRESS_SECV.SSAN_EMPL_CON_NR ) );
How do I write the outer join that will give me all employees and include the ones with no address?
Thanks.

Change the where clause to-
WHERE ((POSITION_EMPLOYEE_SECV.SSAN_EMPL_CON_NR = ADDRESS_SECV.SSAN_EMPL_CON_NR(+)));
Good luck!

Outer Join logic

The following code is an example of how to perform an outer join, in this case with ReportQuery (thanks Doug):
 ExpressionBuilder eb = new ExpressionBuilder();
 ReportQuery rq = new ReportQuery(Employee.class, eb);
 rq.addAttribute("firstName");
 rq.addAttribute("lastName");
 rq.addAttribute("areaCode", eb.anyOfAllowingNone("phoneNumbers").get("areaCode"));
 List<ReportQueryResult> results = (List<ReportQueryResult>) session.executeQuery(rq);My question is about the logic Toplink uses to generate the outer join statement with the "(+)" in the generated sql.
Does Toplink only generate the join statement if the same attribute is chosen in the select statement (in the above example "areaCode")?
Along the same line of questioning, does it matter which attribute was in the get() call? So, in the above example did it have to be areaCode, or could it have been any other attribute of phoneNumber, and it still would have performed the join?
In my case, because the selection attributes are built up dynamicly, should I add all attributes of my child class (my equivalent PhoneNumber class)?

Thanks for your reply Doug.
One last question, hopefully.
I have a parent table with 2 child tables. When attempting an outer join with both, toplink does not attempt to outer join either. I understand why, sort of - as you get an error when attempting this in sqlplus with "(+)" syntax.
I understand that you can outer join > 1 other table to a parent with ansi sql syntax:
 select dept.*,emp.*
 from dept left outer join emp
 on dept.deptno = emp.deptnoWill toplink allow > 1 child table outer join to a parent table?

And , or in outer join

dear all,
since the column of table can not be boolean value, so why and can be used in join query, why "or" can not? anybody can give some example whether "and", "or" used in outer join is correct or wrong.
thanks,

hai lily...
yes i have tried this example
in outer join,yes it is correct,if we want
srpecific data then we can use these
parameters ....
hope u get it..
bye

Full outer Join:ORA-01790

Hi All,
The issue may be silly, but we cant make it out:
    DB : Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - ProdWe are running the below query with no issues:
select t1.text,t2.text text2,t1.line,decode(upper(t1.text),upper(t2.text),1,0) flg

Thanks,

Not sure what is wrong with your version. It might have to do with row_number not working on an empty row (outer joined).
How about this alternative?
The approach is a bit different, but it uses only one access to the user_source view.
select s.lineNo, min(s.text1) text1, min(s.text2) text2, decode(upper(min(s.text1)), upper(min(s.text2)), 1, 0) flag
from
(select decode(u.name, 'COLL_MVIEW_REFRESH_PROC_LBK', u.text) text1
       ,decode(u.name, 'COLL_MVIEW_REFRESH_PROC'
, u.text) text2
       ,u.name,
        row_number() over (partition by u.name order by u.line) lineNo
from user_source u
where u.name in ('COLL_MVIEW_REFRESH_PROC_LBK','COLL_MVIEW_REFRESH_PROC'
/* and u.TYPE = 'PROCEDURE' */
and replace(trim(u.text),chr(10)) is not null
) s
group by s.lineNo

How do I find missing entries in outer join table?

Hi all,
I am trying to find records in table1 that are missing in table2. This is a simple process in SQL, but ABAP is giving me trouble. I want to do this using an outer join.
Example:
Select table1~docnumber
From table1
Left Outer Join table2
On table1docnumber = table2docnumber
Where table2~docnumber IS NULL. (the record is missing in table2)
Note: ABAP gives an error and wants me to use the Having Clause, which is ok, but then ABAP wants me to use Group By, which ok, but then I still get the same syntex error.
Any thoughts on doing this with the outer join and is null options. I do not want to select into two internal tables and compare them.

All,
I am not trying to do a subquery. Just a simple outer join where I know some records are missing in the second table.
Here is the code:
select eban~banfn
into table i_delay_banfn
from eban
left outer join zsmt_prdelay_upd
on eban~banfn = zsmt_prdelay_upd~banfn
where zsmt_prdelay_upd~banfn IS NULL.
Here is the error message:
No fields from the right-hand table of a LEFT OUTER JOIN may appear in
the WHERE condition: "ZSMT_PRDELAY_UPD~BANFN".
select eban~banfn
into table i_delay_banfn
from eban
left outer join zsmt_prdelay_upd
on eban~banfn = zsmt_prdelay_upd~banfn
having zsmt_prdelay_upd~banfn IS NULL.
Please use code tags

BI 7.0 Infoset - Infocube - Left outer join - query

Hi Expert,
A infoset contain Infocube and ODS, linked with left outer join, common fields are PO,PO item. PO account assignment ODS have three keyfields: PO Doc.,Item,account Assignment .
 PO Infocube PO Account Assignment ODS
PO PO item AmtPO Doc. Item AccAssignment Cost object
1000 10 230 1000 10 1 CC1
1001 10 250 1002 10 1 CC1
1002 10 150 1002 10 2 CC2
in BEx result are like this:

1001 10 250 # #
1002 10 150 1 CC1
1002 10 150 2 CC2 ( amount only duplicated)
The issue was that amount gets duplicated. It only occurs if PO has more than one account assignment.
In report, we want show like this

BI Infoset left outer join (NW04s)

I created an Infoset using a left outer join for infoproviders:
- 0FIGL_O10 (GL transaction figures - DSO )
- 0CCA_C03 (CCA Statistical key figures - CUBE)
DSO 0FIGL_O10 is the left table with joins on:
- 0COSTCENTER
- 0FISCPER
The data set returned by Infoset appears to be based on a SQL using an
inner join.
This appears to be a bug.
We are on BI 700 SP 15.

Hi Raynald - I did a demo with few records and it works fine for me. We are on 7, SP14.

FULL OUTER JOIN In InfoSet

Hi, all
Is it possible to make FULL OUTER JOIN in BI InfoSet?
If no, another question - is it possible to switch base InfoProvider? I have an InfoSet with InfoCube1 and DSO1 which I can outer join. I want to outer join InfoCube1 , not DSO1 that's why I need to switch them in the InfoSet.

Hi,
In BI 7.0 Infoset has given chance to include an Info cube also,maximum you can include 2 info Cubes only in a infoset.
check the below link which helps you in understanding of the join conditions so that you can apply to your scenario.

Left Outer Join Not working in BI 7.0 Infoset

Hi All,
I am working on BI 7.0. I have to create a report where I have to display the Target values from a target DSO against the transactional data (Operational data).
I have a DSO where for a subteam value target has been set up on different KPIs.
In the Info Cube, I have transactional data on daily basis per subteam. I have to show the actual and target values.
I have created an Info Set using Target DSO and Daily operational cube, so that I should able to compare the target and actual values of KPIs, for all the subteam values (From DSO, irrespective of whether the data is available in cube for those sub team).
I have used Outer Left Join in the Info set (DSO on left side), but I am unable to see the desired results. It is working just like an inner join.
Any Idea why the Outer Left Join is not working? The DSO has only one fey field called subteam on which I have set outer left join.

Amit

Issues with using Outer join in Data Template

Hi all,
this is my data in two tables .
Table Ronny1
colA colB
1 u
2 v
3 x
Table Ronny2
colC colD
1 q
2 r
This is my data template
<dataTemplate name="MGF" dataSourceRef="Source1">
 <dataQuery>
 <sqlStatement name="Q1" dataSourceRef="Source1">
 <![CDATA[select C, D from Ronny2]]>
 </sqlStatement>
 <sqlStatement name="Q2" dataSourceRef="Source2">
 <![CDATA[select A , B from lokesh1 where A = :C]]>
 </sqlStatement>
 </dataQuery>
 <dataStructure>
 <group name="G1" source="Q1">
 <group name="G2" source="Q2">
 <element name="A" value="A"/>
 <element name="B" value="B"/>
 </group>
 </group>
 </dataStructure>
</dataTemplate>
Now this would give me result as
A B
1 u
2 v
however my requirement is this
A B
1 u
2 v
3 x
that is, i want to display all the rows of table Ronny1 and matching rows from table Ronny2. I tried modifiying my second sql as
<![CDATA[select A , B from lokesh1 where A = :C (+)]]> ( using a outer join)
but this does give me correct data and comes back with the cartesion product.
Can anyone please answer this for me that how can we use the outer join in data templaes.
Thanks
Ronny

hey vetsrini,
sorry for the confusion here,
actually i want to display all the rows from table Ronny1 and i am also pulling in the matching rows from table Ronny2 and my data structure looks as ( pulling in column D from table Ronny2)
<dataStructure>
<group name="G1" source="Q1">
<group name="G2" source="Q2">
<element name="A" value="A"/>
<element name="B" value="B"/>
<element name="D" value="D"/>
</group>
</group>
</dataStructure>
and this is what i want the output to be
A B D
1 u q
2 v r
3 x
Hence the row where A <> C the data in the D column will be null, same as in the case of outer join.
any suggestions
Thx
Ronny

Problem with outer join

Tables
Normal EMP TABLE and dept TABLE
query
SELECT e.deptno,d.dname
FROM emp e , dept d
WHERE E.DEPTNO(+)=D.DEPTNO
AND (e.deptno=20 or e.job='CLERK')
question
When i use the above query i cannot get the extra records from dept table( 40 , OPERATIONS) due to a condition
as long as it is "OR" we cannot use outer joins.
Regardless of that condition i need to get that record(40,OPERATION)
Please reply me it is very urgent for my work now..
regards
Boopathi

select e.deptno,d.dname
FROM emp e , dept d
WHERE E.DEPTNO(+)=D.DEPTNO
AND (e.deptno=20 or e.job='CLERK')
This will only fetch the record for 20, IF you want for deptno 40 then you should remove your AND clause (AND (e.deptno=20 or e.job='CLERK'))
select * from dept
===========
DNAME     DEPTNO

Problem with outer join/insert

I created a test case in scott schema that describes my problem. I use emp table, and I want to have one more table - emp_info - that will store some additional info about employees. Not every employee will have additional info. I can't add a field to emp table - this has to be in an additional table.
I want to display all the emp's in a swing table, and an info if it exists - of course, using outer join. Further more, I want users to be able to enter info in this same table. If info already exists in the emp_info it will be updated, if not a new record is created.
I hope you get the picture.
So, emp_info table is:
create table emp_info(empno number(4), info varchar2(10))
ALTER TABLE "SCOTT"."EMP_INFO"
ADD (CONSTRAINT "PK_EMP_INFO" PRIMARY KEY("EMPNO"))
ALTER TABLE "SCOTT"."EMP_INFO"
ADD (CONSTRAINT "FK_EMP_INFO_EMP" FOREIGN KEY("EMPNO")
REFERENCES "SCOTT"."EMP"("EMPNO"))
In Jdev I create entitiy objects for emp and emp_info, and create View object 'ViewOuter' using these two entities. emp is updatable and empinfo is updatable and reference.
SQL query for the view object is:
SELECT Emp.EMPNO, Emp.ENAME, Emp.JOB, Emp.MGR, Emp.HIREDATE,
Emp.SAL, Emp.COMM, Emp.DEPTNO, EmpInfo.EMPNO AS EMPNO1,
EmpInfo.INFO
FROM EMP Emp, EMP_INFO EmpInfo
WHERE Emp.EMPNO = EmpInfo.EMPNO(+)
I changed View row class of the ViewOuter view:
public void setInfo(String value) {
if (getEmpno1()==null) {
setEmpno1(getEmpno());
setAttributeInternal(INFO, value);
Now I create the table in swing. It works fine - if a user changes info, new record is created or existing updated etc. There is only one problem:
If I change info on an employee, and then requery the view without commiting to the database, I don't see this info. If I try to change it, I get error
(oracle.jbo.TooManyObjectsException) JBO-25013: Too many objects match the primary key oracle.jbo.Key[7499 ].
It seams that the new info is cached, but requerying the view didn't pick it up. And when it creates new row for info PK is violated.
How can I avoid this?

I set up the primari key for emp_info like this:
public void setInfo(String value) {
if (getEmpno1()==null) {
setEmpno1(getEmpno());
setAttributeInternal(INFO, value);
It's set when the user enters info.
What is the difference between transaction.commit and transaction.postChanges?
Posting changes looks like good temp solution. How can I change view object, so it calls postchanges before executing query? Since I can do requery on multiple places in application, this should be handled by the view itself.
Is there any better way?

Problem with outer join with filter on join column

Hi,
In physical layer I have one dimension and two facts, and there's an outer join between the facts.
dim_DATE ,
fact_1 ,
fact_2
Joins:
dim_DATE inner join fact_1 on dim_DATE.DATE = fact_1.DATE
fact_1 left outer join fact_2 on fact_1.DATE = fact_2.DATE and fact_1.SOME_ID = fact_2.SOME_ID
When I run a report with a date as a filter, OBIEE executes "optimized" physical SQL:
select fact1.X, fact2.Y
from
Fact_1 left outer join on fact_1.DATE = fact_2.DATE and fact_1.SOME_ID = fact_2.SOME_ID
where Fact_1.DATE = TO_DATE('2009-05-28' , 'YYYY-MM-DD' )
and Fact_2.DATE = TO_DATE('2009-05-28' , 'YYYY-MM-DD')
The filter on Fact_2.DATE effectively replaces outer join with inner.
Is there a way to disable this "optimization", which is actually very good for inner joins, but doesn't allow outer joins?
Thanks in advance,
Alex
Edited by: AM_1 on Aug 11, 2009 8:20 AM

If you want to perform a Fact-based partitioning with OBIEE (two fact with the same dimension), you have to :
* create in your physical layer for each fact table the joins with the dimension
* create in the Business Model layer ONE star schema with ONE logical fact table containing the columns of your two physical fact table
In this way when you choose minimal one column of your fact1 and one column of your fact2, OBIEE will perform two query against each fact table/dimension, join them with an OUTER JOIN and your problem will disappear.
Cheers
Nico

Problem with outer joins and the class indicator/discriminator

Hello,
I am having a problem defining a query in toplink (10.1.3.3).
In the workbench, I have created a parent and 2 child descriptors. The parent is "AbstractValue", the children are "DefaultValue", classified by the discriminator 'DEF', and "OverrideValue", classified by 'OVR', both located in the same table.
Another descriptor (containing a one-on-one mapping to both a "DefaultValue", and a "OverrideValue") needs to be queried for its 'value'.
The way the query should act is: If an override value (row) exists, this one applies for that object. If an override doesn't exist, return the default value.
The query then comes down to (as I have it now):
builder.getAllowingNull("OverrideValue").getAllowingNull("value").ifNull(builder.get("DefaultValue").get("value")).equal(builder.getParameter(VALUE_PARAM));
The problem is that toplink adds the distinction for the different kind of "values" in the where clause WITHOUT checking for null values e.g. it performs an outer join, but then still checks for the discriminator value thus
....t1.ovr_id = t2.id(+) AND t2.discriminator = 'OVR' AND ...
instead of
... LEFT JOIN values t2 ON (t1.ovr_id = t2.id AND t2.discriminator = 'OVR') ...
This leads to the behaviour that the query returns ONLY the objects that have override and default values.
An overview of the queries (simplified)
Toplink, at the moment, returns only results if both override and default values exists:
SELECT t1.id
t1.def_id,
t1.ovr_id
FROM values t2,
parameter t1,
values t0
WHERE nvl(t2.value, t0.value) = 15 AND
t1.ovr_id = t2.id(+) AND t2.discriminator = 'OVR' AND
t1.def_id = t0.id AND t0.discriminator = 'DEF'
Situation Wanted:
SELECT t1.id
t1.def_id,
t1.ovr_id
FROM parameter t1
LEFT JOIN values t2 ON (t1.ovr_id = t2.id AND t2.discriminator = 'OVR')
JOIN values t0 ON (t1.def_id = t0.id AND t0.discriminator = 'DEF')
WHERE nvl(t2.value, t0.value) = 15
Anyone know if there is some statement I am missing to allow an actual outer join on descriptors containing class indicators/discriminators? A possible rewrite?
Thanks in advance,
Rudy

This is a bug in TopLink's outer join support for Oracle. Currently the outer join is put in the where clause, instead of the from clause, as we do on other platforms. You might be able to fix it by changing your OraclePlatform to return false for shouldPrintOuterJoinInWhereClause().
Please log this bug on EclipseLink, or through Oracle technial support.
There is a workaround using,
descriptor.getInhertiancePolicy().setAlwaysUseOuterJoinForClassType(true);
