Outer join With a constant value

Hi all,
In one of query i have found out that the outer join with a constant value like
to_currency(+)='USD'
to_currency is a column name in a table.can any one please explain this outer join condtn.
Thanks in advance
Senthil

Hallo,
if you write var (+) = constant
var can be equal constant, and also can be null
Compare these 2 queries

  • Outer Join with an 'OR'

    I have a very complicated query to construct that requires the use of 'AND', 'OR', and Outer Joins. Oracle's 9i documentation says you can't use an outer join with an 'OR'.
    Can you suggest how I may return the correct records under the following conditions. There are 3 tables to join. Table A, Table B, and Table C. Tables A & B join with an = to common fields. The problem is with Table C.
    The way the application was designed, it has to track a parent and child relationship. As such, the field to relate may exist in 1 of 2 fields. Let's see if I can draw it out for you.
    Table A - Record 1
    (ID = 1)
    Table B - Record 1
    (ID =1 [this relates to Table A.ID]
    PID = 12345
    CID = 67899
    Site = A)
    Table C - Record 1
    (PID = 12345 [this relates to Table B.PID]
    CID = 67899
    Site = A)
    Table C - Record 2
    (PID = 67899 [This relates to Table B.CID]
    CID = 12345
    Site = A)
    Now, I need to relate Table A to Table B where A.ID = B.ID AND
    ((B.PID = C.PID AND B.CID = C.CID)
    OR
    (B.CID = C.PID AND B.PID = C.CID))
    AND
    B.SITE = C.SITE
    There may or may NOT be related records in Table C. That's the problem. This is where I need the outer join to get the all the records of the 1st two joins and only those that apply from the last join.
    Your help will be greatly appreciated.

    I'd create two queries, a join from b to c in each of those manners and then UNION ALL the results together.
    drop table junk_a;
    create table junk_a (
      id number );
    drop table junk_b;
    create table junk_b (
      id number,
      pid number,
      cid number,
      site varchar2(80) );
    drop table junk_c;
    create table junk_c (
      pid  number,
      cid  number,
      site  varchar2(80) );
    insert into junk_a values (1);
    insert into junk_b values (1, 12345, 67899, 'A');
    insert into junk_c values (12345, 67899, 'A');
    insert into junk_c values (67899, 12345, 'A');
    commit;
    SELECT b.*,
           c.site AS site_c
      FROM junk_b b,
           junk_c c
    WHERE c.pid(+) = b.pid
       AND c.cid(+) = b.cid
    UNION ALL
    SELECT b.*,
           c.site AS site_c
      FROM junk_b b,
           junk_c c
    WHERE c.cid(+) = b.pid
       AND c.pid(+) = b.cid;
    SELECT a.id,
           bc.pid,
           bc.cid,
           bc.site,
           bc.site_c
      FROM junk_a  a,

           c.site AS site_c

  • Outer Join with the query

    I have written the below query, our requirement is, Some employees have "Transport Allowance" but not "Project Allowance". For this, I tried to use OUTER JOIN with this query.

  • Outer join with BETWEEN clause

    Hi All,
    I have 2 tables (A and B) which i need to join. I need all records from table A and matching records from the table B. below is the structure.
    TABLE A (total rows = 10)
    ROW_WID
    GL_DATE
    LOCATION_CODE
    TABLE B (total = 7)
    ROW_WID
    START_DATE
    END_DATE
    LOCATION_CODE
    Initially, we were asked to join based on location_code. In the table B, some of the LOCATION_CODE are missing, which is present in table A.
    We wrote below query
    SELECT A.*, B.START_DATE, B.END_DATE
    FROM A, B
    WHERE A.LOCATION_CODE = B.LOCATION_CODE (+)
    This gives 10 records, where 3 records have START_DATE and END_DATE NULL. because of outer join
    It gave all records from the A table. It worked fine. Now i need to add one more condition where A.GL_DATE between B.START_DATE and B.END_DATE
    If i write this
    SELECT A.*, B.START_DATE, B.END_DATE
    FROM A, B
    WHERE A.LOCATION_CODE = B.LOCATION_CODE (+)
    AND A.GL_DATE BETWEEN B.START_DATE and B.END_DATE
    This gives me only 7 records. IS IT POSSIBLE TO ADD OUTER JOIN with BETWEEN clause.

    Hi All,
    I'm in a similar situation,
    I have a complex query, everything is working fine, except this part (I will simplify everything, removing other stuffs because I need help only on the following condition)
    SELECT *
    from transaction t, card c
    where c.card_id = t.card_id (+)
    and t.trn_date between to_date ('01/01/2012','dd/mm/yy') and ('01/01/2013,'dd/mm/yy')
    How could i OUTER JOIN the between condition?
    I tried with
    and t.trn_date between to_date ('01/01/2012','dd/mm/yy') (+) and ('01/01/2013','dd/mm/yy') (+)
    but returns a "missing expression" error.
    Surely I'm missing some stupid thing about it, could you help me on this? (probably because I'm talking about parameters and I cannot put the outer join on a value)
    How can I rewrite the condition in order to satisfy what I'm trying to accomplish?
    Thanks in Advance,
    Alex

  • 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

  • Outer Join with Where Clause in LTS

    HI all,
    I have a requirement like this in ANSI SQL:
    select p1.product_id, p1.product_name, p2.product_group
    from product p1 left outer join product_group p2 on p1.product_id = p2.product_id
    and p2.product_group = 'NEW'
    In Regular SQL:
    select p1.product_id, p1.product_name, p2.product_group
    from product p1, product_group p2
    WHERE p1.product_id *= p2.product_id and p2.product_group = 'NEW'
    In OBIEE, I am using a left outer join between these two in Logical table Source, and also, Gave
    p2.product_group = 'NEW' in WHERE clause of LTS.
    This doesn't seem to solve purpose.
    Do you have any idea how to convert WHERE clause in physical query that OBIEE is generating to something like
    product p1 left outer join product_group p2 on p1.product_id = p2.product_id AND p2.product_group = 'NEW'
    I am using Version 10.1.3.4.1
    Creating an Opaque view would be my last option though.

    Hello
    I have read your post and the responses as well. and I understand that you have issues with the Outer Join with where Clause in LTS.
    Try this solution which worked for me (using your example ) -
    1. In the Physical Layer created a Complex join between PRODUCT and PRODUCT_GROUP tables and use this join relationship :
    PRODUCT.PROD_ID = PRODUCT_GROUP.PROD_ID  AND  PRODUCT_GROUP.GROUP_NAME = 'MECHANICAL' 
    2. In the General Tab of PRODUCT table LTS add PRODUCT_GROUP  table and select Join Type as Left Outer Join.
    3. Check Consistency and make sure there are no errors .
    when you run a request you should see the following query generated -
    select distinct T26908.PROD_ID as c1,
         T26908.PROD_NAME as c2,
         T26912.GROUP_NAME as c3
    from
         PRODUCT T26908 left outer join PRODUCT_GROUP T26912 On T26908.PROD_ID = T26912.PROD_ID and T26912.GROUP_NAME = 'MECHANICAL'
    order by c1, c2, c3
    Hope this works for you. If it does please mark this response as 'Correct' .
    Good Luck.

  • Outer join with effective date in peoplesoft query

    Hi,
    I'm trying to join two tables using outer join. Both tables are effective dated:
    Dept_Tbl: dept_id, status, effdt
    Tips_Tbl: dept_id, tips_id, effdt
    Not all records in Dept_Tbl are in Tips_Tbl. I need to get all active depts and their most recent tips_id if they have one.
    select a.dept_id, b.tips_id
    from dept_tbl a, tips_tbl b
    where a.status = 'Active'
    and a.effdt =
    (select max(a_ed.effdt) from dept_tbl a_ed
    where a.dept_id = a_ed.dept_id
    and a_ed.effdt <= SYSDATE)
    and b.dept_id(+) = a.dept_id
    and b.effdt =
    (select max(b_ed.effdt) from tips_tbl b_ed
    where b.dept_id = b_ed.dept_id
    and b.tips_id = b_ed.tips_id
    and b_ed.effdt <= SYSDATE)
    The query only returns records that are in both tables.
    Is there a way for outer join to work with effective dates?
    Thanks in advance,
    Reg

    Here is an example of one solution. Note the use of NVL on both sides of the equal sign since both sides could be NULL in the case of the outer join
    with dept_tbl as (select 1 dept_id, SYSDATE effdt FROM DUAL),
         tips_tbl as (select 1 dept_id, NULL effdt FROM DUAL)
    select a.effdt
      from dept_tbl a,
           tips_tbl b
    where b.dept_id(+) = a.dept_id
       and NVL(b.effdt, SYSDATE) = NVL((select max(b_ed.effdt)
                                          from tips_tbl b_ed
                                         where b.dept_id = b_ed.dept_id

  • Case statement resulting into Left outer join with other tables

    Hi All ,
    I am facing a stuation where a Case statement on one of the logical columns in Answers is resulting into a left outer join with a table in the query.
    If we remove the case stmt, the table is not being acessed.
    The case stmt is a simple one and no other logical column is being accessed in the case stmt.
    Please advice .
    Thanks.

    Hi Sai,
    No ..we dont have any left outer join ...its just that I am selecting measure from F1 which has a confimred dimension D1 with F2.Now when I dont have case stmt on measure from F1(Case stmt is something like : CASE WHEN "- P table"."P Column" = 'Y' THEN 'Right' ELSE 'Wrong' END), then it doesnt query F2.
    However as soon as I introduce the case stmt ,the query creates a left outer join with F2.
    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

  • Outer join with where clause in the universe

    Hi,
    I have two tables such as:
    Patient Table (P)                          Territory Table (T)
    P. Alignment ID --------------------------   T.Alignment ID
    P. Patient ID                                    T. Region
    Two tables are joined on alignment ID, follow is how the data looks like
    When i run the query only on Patient Table  i get the following
    e.g.
    Select P.Patient ID, P.Alignment ID
    from Patient Table (P)
    Where P.Data_date=P.Latest data date
    ----Note that there is a Where clause here always & i get the following result
    P.Patient ID         P.Alignment ID      
        1                            1a
        2                             2a
        3                            3a
        4                            Null
        5                            Null
    Now when i join two tables on Alignment ID
    e.g.
    Select P.Patient ID, P.Alignment ID,T.Region
    from Patient Table (P)
    LEFT OUTER  JOIN Territory Table (T)
    ON P. Alignment ID =  T.Alignment ID
    Where P.Data_date=P.Latest data date
    AND T.Data_date=T.Latest data date
    Following is the result:
    P.Patient ID         P.Alignment ID      
        1                            1a
        2                            2a
        3                            3a
    Even with the left outer join it is not brining in the Null values , it seems that because of the WHERE clause the LEFT OUTER is working as a INNER join.
    How can i get the Null rows with my join to the territory table ?
    Please Advise,
    Thanks,
    Sheikh

    its not letting me atatched the excel extract but the data is simple as i shown above e.g.

    P. Patient ID                                    T. Region
    Two tables are joined on alignment ID, follow is how the data looks like
    When i run the query only on Patient Table  i get the following
    e.g.
    Select P.Patient ID, P.Alignment ID
    from Patient Table (P)
    Where P.Data_date='01-OCT-2014'
    ----Note that there is a Where clause here always & i get the following result
    P.Patient ID         P.Alignment ID      
        1                            1a
        2                             2a
        3                            3a
        4                            Null
        5                            Null
    Now when i join two tables on Alignment ID
    e.g.
    Select P.Patient ID, P.Alignment ID,T.Region
    from Patient Table (P)
    LEFT OUTER  JOIN Territory Table (T)
    ON P. Alignment ID =  T.Alignment ID
    Where P.Data_date='01-OCT-2014'

    Following is the result:
    P.Patient ID         P.Alignment ID      
        1                            1a
        2                            2a
        3                            3a
    Now the whole issue is that the condition in the WHERE clause is making it act like a inner join and iw ant the NULL rows to appear

  • Query Question: Combine outer join with max() statement

    Hi Folks,
    I have been banging my head on this for a while now and am asking from some advice.
    I have a Project Completion Report that pulls information from a number of tables:
    1) Program (PK: ID)
    2) Project (PK: ID, FK: Program_ID constrained to Program.ID)
    3) Project_Monthly (PK: ID, FK: Project_ID constrained to Project.ID)
    4) Status_Report (PK: ID, FK: Project_ID constrained to Project.ID)
    The Status_Report table has a Record_Date field and holds a BLOB with the status reports for all the projects. In the best of all possible worlds, every project would have a status report, but, obviously, some have no status reports.
    I have been asked to extend the Project Completion Report. It currently shows:
    1) Program Number (Program.Program_Number)
    2) Program Name (Program.Program_Name)
    3) Project (Project.Project_Name)
    4) Projected Completion Date (Project_Monthly.Current_Date_Production)
    We would like to add the latest status report. So I started with something that works in another report, which is to get the ID from the Status_Report table for the record that has the maximum date value in the Record_date that matches the Project in the current Program. But this other query is looking at one program at a time. The Project Completion Report is showing all programs with projects that complete within a certain time frame.
    The requirement is to show all projects that will complete within a time frame and to display the ID of the most recent status report (I use javascript to turn this into a downloadable link). However, whenever I try something like:
    AND Status_Report.Record_Date =
    (select MAX(Status_Report.record_date) from Status_Report
    where Status_Report.ID = Project.ID)I loose all projects that have no status reports associated with them.
    How can I keep all the projects that fulfill the criteria of completing within a specified time frame and add the ID, if it exists, of the most recent status report?
    I thank you for your time and assistance. Please let me know how I can clarify the problem more clearly.
    Yours,
    Petie

    I had thought I finally solved it. Alas, it wasn't yet to be.
    I created a view with the following select statement:
    select p.program_number, p.program_name,
    pj.id as pj_id, pj.project_name, pjm.in_prod_current, pjm.record_date as pjm_record_date,
    prs.id as prs_ID, prs.record_date as prs_record_date
    from program p, project pj, project_monthly pjm,
    project_status_report prs
    where p.id = pj.program_id
    and pj.id = pjm.project_id
    and pj.id = prs.project_id (+);Then, I selected from the view and the project_status_report table, performed an outer join on those (filtered to only the current month's project records) and filtered by the maximum date for each project.
    Here is the resulting query:
    select pc.program_number, pc.pj_id, pc.project_name, pc.in_prod_current,
    pc.pjm_record_date, pc.prs_id
    from project_completion pc,
    project_status_report prs
    where trunc(pjm_record_date, 'mon') = trunc(sysdate,'mon')
    and prs.id = pc.prs_id (+)
    and pc.prs_record_date =
    (select max(mprs.record_date)
    from project_status_report mprs
    where mprs.project_id = pc.pj_id)However, I am still not getting the projects for which there are no status reports.
    Verflixt und zugenaeht!
    It seems that I want to compare based upon the record_date of the status report, but get the ID back. Can I use DECODE for that? Can I get the MAX(prs.record_date), but return only the prs.ID? Because if I include the ID in the select statement, I get too many matches, but if I don't then I don't have the ID, which is needed.
    Any suggestions?
    Thanks, Petie
