Equal Join and Outer Join in OBIEE

Hello expert,
I think the default join in OBIEE is Outer Join. So no matter what join conditions that I specify on the physical layer, the result that I get in the presentation layer is still outer join.
How to specify the equal join or inner join in Business and Logical layer?

Hello,
Thank you for your reply. However it does not work. I got the following message:
[nQSError: 32005] The object "Fact - Fruit" bc if type 'LOGICAL TABLE SOURCE': is missing a foreign key or a complex join in the join graph.
The situation that I have is:
Fact table: "Fact - Fruit"
List of value table (look up table): "dim_list_of_values"
I am only interested in the type in the "dim_list_of_values" table where equals to "Apple". So I only want to join the "Fact - Fruit" and "dim_list_of_values" with those records with "Apple" type.
It sounds to me that I am unable to define a freign key.

Example
Output a list of all flights from Frankfurt to New York between September 10th and 20th, 2001 that are not sold out:
DATA: DATE   LIKE SFLIGHT-FLDATE,
      CARRID LIKE SFLIGHT-CARRID,
      CONNID LIKE SFLIGHT-CONNID.
SELECT FCARRID FCONNID F~FLDATE
    INTO (CARRID, CONNID, DATE)
    FROM SFLIGHT AS F INNER JOIN SPFLI AS P
           ON FCARRID = PCARRID AND
              FCONNID = PCONNID
    WHERE P~CITYFROM = 'FRANKFURT'
      AND P~CITYTO   = 'NEW YORK'
      AND F~FLDATE BETWEEN '20010910' AND '20010920'
      AND FSEATSOCC < FSEATSMAX.
WRITE: / DATE, CARRID, CONNID.
ENDSELECT.
If there are columns with the same name in both tables, you must distinguish between them by prefixing the field descriptor with the table name or a table alias.
Note
In order to determine the result of a SELECT command where the FROM clause contains a join, the database system first creates a temporary table containing the lines that meet the ON condition. The WHERE condition is then applied to the temporary table. It does not matter in an inner join whether the condition is in the ON or WHEREclause. The following example returns the same solution as the previous one.

DATA: DATE   LIKE SFLIGHT-FLDATE,

      AND FSEATSOCC < FSEATSMAX.
WRITE: / DATE, CARRID, CONNID.
ENDSELECT.
Note
Since not all of the database systems supported by SAP use the standard syntax for ON conditions, the syntax has been restricted. It only allows those joins that produce the same results on all of the supported database systems:
Only a table or view may appear to the right of the JOIN operator, not another join expression.
Only AND is possible in the ON condition as a logical operator.
Each comparison in the ON condition must contain a field from the right-hand table.
If an outer join occurs in the FROM clause, all the ON conditions must contain at least one "real" JOIN condition (a condition that contains a field from tabref1 amd a field from tabref2.
Note
In some cases, '*' may be specified in the SELECT clause, and an internal table or work area is entered into the INTO clause (instead of a list of fields). If so, the fields are written to the target area from left to right in the order in which the tables appear in the FROM clause, according to the structure of each table work area. There can then be gaps between table work areas if you use an Alignment Request. For this reason, you should define the target work area with reference to the types of the database tables, not simply by counting the total number of fields. For an example, see below:
Variant 3
... FROM tabref1 LEFT [OUTER] JOIN tabref2 ON cond
Effect
Selects the data from the transparent database tables and/or views specified in tabref1 and tabref2. tabref1 und tabref2 both have either the same form as in variant 1 or are themselves join expressions. The keyword OUTER can be omitted. The database tables or views specified in tabref1 and tabref2 must be recognized by the ABAP-Dictionary.
In order to determine the result of a SELECT command where the FROM clause contains a left outer join, the database system creates a temporary table containing the lines that meet the ON condition. The remaining fields from the left-hand table (tabref1) are then added to this table, and their corresponding fields from the right-hand table are filled with ZERO values. The system then applies the WHERE condition to the table.
Left outer join between table 1 and table 2 where column D in both tables set the join condition:

Inner join and outer join

Inner join and outer join in infosets

hi everyone,
i have a doubt in infosets...
when and why we use inner and outer joins(right outer join and left outer join) for infoset
please give a real time scenario........
Thanks in advance.
Bye.

Hello,
Inner join:
For example, the requirement is to show all sales documents where you have delivery exists. In this case, you join both sales ods and delivery ods in a infoset as inner join. This will match the record against the reference documents and pull only matched records.
Outer Join:
Suppose you want to pull all billing/invoice details along with their FI documents related data in a report. Assume that always there might be a situation that invoice exists but not posted to FI, however, you want to have all billing documents details either it has FI document or not. In this case, you link both Billing data and FI document data in a outer join. This will pull all invoices data either FI document exists or not. Other words, you want to show one side of data always but adding additional details from differenent source if data exists.
Hope, it clarifies your doubt. Let me know if any questions.
Thanks

SYNTAX "INNER JOIN and OUTER JOIN"

Hi Experts,
I think LEFT JOIN,INNER JOIN syntax is in ANSI.
I know that Oracle has got its own alternate(+) operator to serve the purpose.
Please tell me whether INNER JOIN,OUTER JOIN,LEFT JOIN,LEFT OUTER JOIN,RIGHT OUTER JOIN these syntaxes present in ORACLE 8I.
If not in 9i Or highr versions are they existing?
Thanks in advance,
Ananth
null

Hi,
8i has inner join. (+) syntax supports LEFT or RIGHT OUTER JOIN.
FULL OUTER JOIN is supported in 9i, which introduces the JOIN keyword.

Equi Join and Outer join using outer keyword

Hi,
First lets take the create statment for scott schema.
create table scott.emp_details(empno number, bonus_date date);
Insert Into Scott.Emp_Details Values(7369, To_Date('01-jan-2013'));
Insert Into Scott.Emp_Details Values(7499, To_Date('05-jan-2013'));
Insert Into Scott.Emp_Details Values(7521, To_Date('10-jan-2013'));
Insert Into Scott.Emp_Details Values(7566, To_Date('01-feb-2013'));
Insert Into Scott.Emp_Details Values(7654, To_Date('05-feb-2013'));
commit;lets also consider the basic scott.emp and scott.dept tables
Now I would like to equi join emp table deptno col with dept table deptno col and left outer join emp table hiredate with emp_details bonus_date and empno col in emp_details can be joined(Equi Join) with empno col of emp table if needed .The outer join has to be placed using the keyword (left/right)outer join
The select statement can have all the detials of emp table .The requirement may look weird but we have some such requirement.
Please suggest

It's best not to create your own tables in Oracle-supplied schemas, such as SCOTT. Use your own schema for your own tables.
lets also consider the basic scott.emp and scott.dept tablesI see; you're using the standard scott,emp and scott.dept tables, plus the emp_details table you posted above.
Now I would like to equi join emp table deptno col with dept table deptno col and left outer join emp table hiredate with emp_details bonus_date and empno col in emp_details can be joined(Equi Join) with empno col of emp table if needed .The outer join has to be placed using the keyword (left/right)outer join

Joins and Outer joins

Sorry for being a newbie!
I was using JPQL to grab data from one table that requires an outer join to another table.
I thought I could do this:
select a.f1,a.f2,b.f3 from A a LEFT OUTER JOIN B b
where a.id = b.id and
a.match = b.match;
A and B are entities and I need to join with two columns. Can someone please tell me what I'm doing wrong.
Thanks!

Thanks!Generally you do these kind of mappings through the Entities. For example, you can have a OneToMany / ManyToOne mapping between the two entities. Check out the Toplink reference guide for some examples on how to do this:
[http://www.oracle.com/technology/products/ias/toplink/jpa/resources/toplink-jpa-annotations.html#ManyToOne|toplink JPA annotations reference]
Even if you are not using Toplink, this is the same for all persistence providers.

Oute Join and Inner Join

Hi,
I need to join three tables, based on some conditions (EKPO, EKBE and EKKN Note: All PO line items from EKPO will have a movement associated in the EKBE Table. Capture all PO line items where no matches found in the EKPO-EKBE join)
for the above requirement shall I write my query like this?
SELECT ekpo~ebeln

                                           ekpo~ebeln IN s_ebeln.
Shall I use both Outer Join and Inner join in one Query?
Please correcte me.
Thanks

Hi,
You can use both inner join and outer join in the same select statement.
Ensure first all the inner joins between tables are declared and put the left outer join at the end.

Invalid combinations of joins involving outer joins

Hi all, I have the following problem
Scenario: I created 6 custom folders:
Tasks (with measures)
Type
Criticity
Status
Owners
Assignees
The first folder is used to retrieve how many tasks (COUNT(tasks)) have a particular type or status or a combination between them, and the others 5 are dimensions.
I create 6 joins starting always from the dimensions in this way (radio buttons):
Detail item values always exist in master folder (Typical)
Outer join on detail
where the master is always a dimension and the detail is always the custom folder with the measures.
I put the outer join on the custom folder with the measures because I want to show '0' in case I don't have any record on this folder for a specific attribute on a dimension (the join fails).
I saw that if I put the outer join on the master (dimensions), when the join fails I don't see at all the information regarding that particular dimension.
For example
I select 2 folder: Tasks and Assignee
join: Tasks.task_id (+) = Assignee.task_id
Result:
TASK ASSIGNEE
10 Mr. A
20 Mr. B
30 Mr. C
0 Mr. D
Just to make a test, If I change the join on Administrator putting :
Detail item values might not exist in master folder
Outer join on master
...the result is this
TASK ASSIGNEE
10 Mr. A
20 Mr. B
30 Mr. C
...I don't see the last record.
The customer asked to see always the record with task =0 (if exists), so I joined all the custom folders as I expalned above, but when I try to link (on Discoverer Plus) more than two tasks I have the following error:
Invalid combinations of joins involving outer joins
So, my question is this: how can I avoid this error ? Does it exist any trick or another way to link the custom folders (showing always the records with '0' when the join doesn't retrieve nothing ) ?
Thanks in advance
Alex

Well I will take a stab at answering this. The problem is not knowing what is in your custom folders. Also not knowing the specifics on your Discoverer Join definitions. On something like this you may be better going to Oracle support, since they can start a Web Conference and see exactly what you see, and can check out the various possibilities. All we here can do is make guesses, and the guesses could be wrong.
You do have to be careful in your join definitions in Discoverer. You have to pick the correct table as the Master table, and the correct table as the Detail table. Mess that up and you can mess yourself up. So my first though is check your join definition. Sounds like you want assigned to be the master table. Then tasks would be the detail table.
Then you want to pick the option that detail items might not exist in master. Which it looks like you have done.
Then for the other options, Oracle, in my mind, does the opposite of what I would think to pick. If you pick OUTER JOIN ON DETAIL, that will include the Master items with no detail items. So that is what you need to pick.
Looks like you did the OUTER JOIN ON MASTER, which means will include detail items with no master. Since you had a master with no detail, it will not show, and that is why the Mr. D does not show.
I always have to do the help on this because it is opposite of what I would expect - my mind thinks outer join on master should include all masters. Nope, it has to be the outer join on detail to do that.
The master with no detail will probably show a NULL value in the column for the detail, instead of 0. You could convert the null value to display as a 0.
Hope this helps a bit. Just remember that I am guessing/speculating on a possible cause.

Why Inner join or Outer join is not used for Pool or Cluster tables ?

Hi SAP-ABAP Experts .
With Due Regards .
May u explain me why Inner join or Outer join is not useful for Pool or Cluster tables ?
because peoples advised not use Joins for Pool and Cluster tables , What harm will take place , If we do this ?
Best Regards to all : Rajneesh

Both Pooled and Cluster Tables are stored as tables within the database. Only the structures of the two table types which represent a single logical view of the data are defined within the ABAP/4 Data Dictionary. The data is actually stored in bulk storage in a different structure. These tables are commonly loaded into memory (i.e., 'buffered') due to the fact they are typically used for storing internal control information and other types of data with little or no external (business) relevance.
Pooled and cluster tables are usually used only by SAP and not used by customers, probably because of the proprietary format of these tables within the database and because of technical restrictions placed upon their use within ABAP/4 programs. On a pooled or cluster table:
Secondary indexes cannot be created.
You cannot use the ABAP/4 constructs select distinct or group by.
You cannot use native SQL.
You cannot specify field names after the order by clause. order by primary key is the only permitted variation.
I hope it helps.

Difference between physical join and logical join

Hi Gurus,
Can anyone tell me what is the difference between physical join and logical join
Thanks,
Chandra

Hi,
A physical join is at the physical layer and defines the join between two physical tables. Logical joins live at the BMM (logical) layer and define a join between two logical tables.
The important differentiation is that at the BMM layer you do not tell the OBIEE server how to do the join, you just tell it that there is a relationship between these two logical entities. When the server comes to this logical join it will use the information in the physical joins and decides how the two logical tables are joined together.
In BMM you use complex joins to establish which logical tables are joined which another, the OBI EE server will go to the physical level to search the physical join to make the query. You can also use physical joins in the BMM to override the join in the physical layer but only in very specific conditions.
If you also set complex join in the physical layer OBI EE won't be able to construct the physical query.
Hope this answers your question.
Award points if helpful.
Thanks,

Inner join Vs Outer join with ABAP code...?

Inner join Vs Outer join with ABAP code...?

Inner Join means, it will not select that recor at all, unless there is a matching entry in the second table.
suppose table VBAK INNER join table VBAP on VBAKVBELN = VBAPVBELN.
In this case, if there are no entries in VBAP, the header entry also will not show up.
But in case of OUTER JOIN, even if there is no items, it will show the header entry(VBAK) with blank columns for fields from item table.(VBAP)
here is one sample for inner join.
SELECT   A~EBELN
           A~EKORG
           A~EKGRP
           A~BSART
           A~LPONR
           A~LOEKZ
           A~LIFNR
           A~RESWK
           B~AEDAT
           B~WERKS
           B~MATNR
           B~MENGE
           B~EBELP
           B~ELIKZ
           B~PLIFZ
           B~PSTYP
           B~KNTTP
           B~MATKL
           B~ZZD_PLANT
           FROM EKKO AS A INNER JOIN EKPO AS B
           ON
           AEBELN = BEBELN
           INTO CORRESPONDING FIELDS OF TABLE T_DATA
           FOR ALL ENTRIES IN T_EKET
           WHERE
           A~EBELN EQ T_EKET-EBELN AND
