Help with outer joins in Oracle!!

so far this is what i've come up with and the code below does not work. Can anyone please help me on how the sytanx of left joins and how to use multiple left joins in a single query in oracle?
SELECT a.*, b.Position_CD, c.Skill_CD, d.Team_Name, d.Team_Country, d.Club, e.Structure_Name
FROM Roster a, Roster_position b, roster_skill c, Team d, Team_Structure e
where (a.Roster_ID = ((b.Roster_ID= c.Roster_Id(+)) b.roster_id(+)).......
I dont' know how to add more left joins!
Here is the query I'm trying to duplicate (which is a query from Ms Access databaase which works fine).
SELECT a.*, b.Position_CD, c.Skill_CD, d.Team_Name, d.Team_Country, d.Club, e.Structure_Name
from ((Roster a LEFT JOIN (Roster_Position b LEFT JOIN Roster_Skill c ON b.Roster_ID=c.Roster_ID) ON a.Roster_ID=b.Roster_ID) LEFT JOIN Team d ON a.Team_CD=d.Team_CD) LEFT JOIN Team_Structure e ON a.Team_Structure_CD=e.Team_Structure_CD
ORDER BY a.Roster_Id;
Any help or comments are greatly appreciated

First,
I am not one of the leading SQL brains here...but I'm taking a stab, nonetheless.
Second,
Here's my best guess - and it seems to me that it should work as there are not two outer joins between any two tables. I hope I decoded your joins correctly - quite a mess that Access syntax!
SELECT a.*, b.position_cd, c.skill_cd, d.team_name, d.team_country, d.club, e.structure_name
FROM ROSTER a, ROSTER_POSITION b, ROSTER_SKILL c, TEAM d, TEAM_STRUCTURE e
WHERE a.roster_id = b.roster_id(+)
AND b.roster_id = c.roster_id(+)
AND a.team_cd = d.team_cd(+)
AND a.team_structure = e.team_structure(+);Third,
As an architect-dude, it seems to me that you have a serious
modeling problem to need so many outer joins in such a basic
grab of data. In any scale other than minute, the performance
of this model will suffer dramatically. Specifically, why can't
ROSTER have an equijoin with TEAM and with TEAM_STRUCTURE - as they
appear to be lookup tables...
Good Luck
(I'm certain you'll get better SQL from the others),

    I want to display data for each entity available in entity table
    What is wrong with this query??
    Select ps.date_time,ps.entity_id,et.entity_id from entity et left outer join PS ps on (et.entity_id = ps.entity_id)
    This query gives me result like
    26-DEC-08     1     1
    26-DEC-08     3     3
    26-DEC-08     6     6
    26-DEC-08     10     10

    27-JAN-09     1     1
    But the unmatching ids are not displaying when i am using the outer join..please help me..

    Almost there.
    In this case you need a partitioned outer join, partitioning by date_time:
    SQL> Select ps.date_time
      2       , ps.entity_id
      3       , et.entity_id
      4    from ps partition by (ps.date_time)
      5         right outer join entity et on (et.entity_id = ps.entity_id)
      6  /
    DATE_TIME                                 ENTITY_ID  ENTITY_ID
    26-12-08 00:00:00,000000                          1          1

  • Need help with outer joins

    I have the following table structure,
    Table - 1_
    ID | Information
    1 | abcadskasasa
    2 | asdasdasdasd
    3 | saeqdfdvsfcsc
    Table - 2_
    ID | PID
    1 | 12
    1 | 13
    2 | 14
    1 | 15
    1 | 16
    2 | 12
    Table - 3_
    ID | PARID
    1 | 12
    2 | 14
    1 | 15
    Now I want to select for each ID in table 1, the count of number of PID from table 2 and count of number of PARID from table 3.
    Desired output:_
    ID | COUNT_PID | COUNT_PARID
    1 | 4 | 2
    2 | 2 | 1
    3 | 0 | 0
    Could anyone please help me out with this. I am trying to make use of outer joins, but as I work mostly on the front end so, not able to come up with a proper solution for the above.
    Thanks in advance,
    Tejas

    Hi, Tejas,
    You might have been doing the outer join correctly.
    There's another problem here: joining table_1 to two other tables with which it has a one-to-many relationship.
    If you were joining table_1 to just one other table, you could say:
    SELECT       t1.id
    ,       COUNT (t2.pid)     AS count_pid
    FROM              table_1     t1
    LEFT OUTER JOIN  table_2     t2     ON     t1.id     = t2.id
    GROUP BY  t1.id
    ORDER BY  t1.id;You could have done the exact same thing with table_3 instead of table_2.
    But you can't do the same thing with both table_2 and table_3 at the same time: that would be like cross-joining table_2 and table_3. Instead of showing id=1 having count_pid=4 and count_parid=2, you would get cout_pid=8 and count_parid=8 (since 8 = 4 * 2).
    You can do a separate GROUP BY on (at least) one of the tables.
    This gets the right results. In the main query, there is only one one-to-many relationship.
    WITH  t3_summary     AS
         SELECT    id
         ,       COUNT (parid)     AS count_parid
         FROM       table_3
         GROUP BY  id
    SELECT       t1.id
    ,       COUNT (t2.pid)     AS count_pid
    ,       MAX (t3.count_parid)     AS count_parid
    FROM              table_1     t1
    LEFT OUTER JOIN  table_2     t2     ON     t1.id     = t2.id
    LEFT OUTER JOIN      t3_summary     t3     ON     t1.id     = t3.id
    GROUP BY  t1.id
    ORDER BY  t1.id;

  • Help with outer joins? NVL?

    HI,
    I have two reports I am creating, one for October and one for november.
    The query is below so you can see what I am trying to do. There is a difference of about two hundred accounts, I want to see which accounts were in October and not in November. How can I view the different accounts and list them along side the november accounts or if this can't be done, how can I at least see the accounts which differ between the months? I am thinking that I need to build one report as an inline-view in the from clause, and then do an outerjoin on that aliased table, but am not sure on the syntax. Also, how can I use the NVL function to put in a value for the NULL columns?

    Can any one please give me help in getting this done
    Thanks

    Hi,
    As SB pointed out, you'd better provide tables and data in order to be helped more efficiently.
    Anyway, you may want to investigate the use of NVL and/or DECODE so that you can translate NULL into valid values so they are returned to your select statement.
    HTH,

  • How to use OUTER JOIN in Oracle Answers Filters?

    Hi, I need to have a filter on an 'Oracle Answers' report.
    The query from the NQQuery.log appears as below. (I have simplified the SELECT clause here for easy reading)
    SELECT t692.enquiry_business_route AS c1,
    t692.enquiry_id AS c11, t913.YEAR AS c12,
    t913.full_date AS c13, t666.surname AS c14,
    t666.post_code AS c15, t855.company_name AS c16,
    t983.notes AS c30
    FROM
    mkt_dw_enev_enhi_dim t983,
    mkt_dw_key_partner_dim t855,
    mkt_dw_event_type_dim t821,
    mkt_dw_customer_dim t666,
    mkt_dw_time_dim t913,
    mkt_dw_enquiry_event_fact t692
    WHERE (
    t692.enquiry_id = t983.enqu_id
    AND t666.customer_dim_key = t692.customer_dim_key
    AND t692.event_date_time_key = t913.time_dim_key
    AND TRUNC(t983.event_date)= t913.FULL_DATE
    AND t692.event_type = t821.event_type_dim_key
    AND t692.key_partner_dim_key = t855.key_partner_dim_key
    AND t821.event_type_category = 'RECEIVE_FEE'
    AND t913.YEAR = 2009
    and t692.enquiry_id = 535986
    For the following two lines I would like to have the OUTER JOIN.
    AND t692.event_type = t821.event_type_dim_key(+)
    AND t821.event_type_category(+) = 'RECEIVE_FEE' (THIS IS THE FILTER CONDITION, AT THE MOMENT IT DOESN'T WORK WITH OUTER JOIN SYMBOL)
    Please could you let me know the best way of achieving the above.
    Thanks
    Srikanth

    In the BMM layer in the join condition you will be able to specify the join to be (left, right or full outer join).
    You can even add the required table in the LTS(logical table source) and also specify a left, right or full outer join there as well.
    There is an interesting work around as mentioned in the below blog to get to the Outer join results with out changing anything in rpd but in Answers.

  • Update with Outer Join, round 2

    Thanks for those of you who helped me out on the first one (I never thought that you could use a one-row SELECT like that).
    However, here is a new version of my problem:
    I have three tables.
    Table_1 has a column that needs to be updated based on values in Table_2 and Table_3.
    Both Table_1 and Table_2 have values used to determine which Table_3 row to use.
    However, not every Table_1 row has a corresponding Table_3 row, in which case the Table_3 value to use is assumed to be 1.
    The tables and corresponding columns are:
    TABLE_1
    value_1 - the value to be updated
    key_2 - a pointer to TABLE_2
    key_3a - a pointer to TABLE_3, or a dummy value if there is no corresponding TABLE_3 record
    TABLE_2
    key_2 - the primary key
    key_3b - a secondary pointer to TABLE_3
    value_2 - a value to be used in calculating TABLE_1.value_1
    TABLE_3
    key_3a - the first part of the unique key
    ley_3b - the second part of the unique key
    value_3 - a value to be used in calculating TABLE_1.value_1
    If there is a row in table_3 that matches the table_1.key_3a and table_2.key_3b values (where table_2.key_2 = table_1.key_2):
    set table_1.value_1 = table_2.value_2 * table_3.value_3
    If there is no such row in table_3:
    set table_1.value_1 = table_2.value_2
    I want to do something like this:
    UPDATE table_1 t1
    SET value_1 =
    SELECT t2.value_2 * NVL(t3.value_3, 1)
    FROM table_2 t2
    LEFT JOIN table_3 t3
    ON (t3.key_3b = t2.key_3b and t3.key_3a = t1.key_3a)
    WHERE t2.key_2 = t1.key_2
    However, Oracle does not allow t1 to be referenced in the ON clause of the outer join.
    (Assume that every key_2 value in table_1 is in table_2 as well - it is only the key_3 value that can be a dummy.)
    If I move "t3.key_3 = t1.key_3" to the WHERE clause, then t1.value_1 is null for rows without the corresponding table_3 value.
    I can do it with a clone of table_1 using ROWIDs:
    UPDATE table_1 t1
    SET value_1 =
    SELECT t2.value_2 * NVL(t3.value_3, 1)
    FROM table_1 t1a
    JOIN table_2 t2
    ON t2.key_2 = t1a.key_2
    LEFT JOIN table_3 t3
    ON (t3.key_3b = t2.key_3b and t3.key_3a = t1a.key_3a)
    WHERE t1a.row_id = t1.row_id
    However, is there an easier way to do this using ANSI joins (i.e. without (+) syntax)?
    I have this feeling I am missing something reasonably obvious here.

    I have this feeling I am missing something reasonably obvious here.You might want to refer to my post in your original thread how to use join views in updates. You can use ANSI join syntax there, too:
    Re: Update with Outer Join
    You would end up with something like this (note: untested):
    UPDATE
      SELECT t1.value_1, t2.value_2 * NVL(t3.value_3, 1) as new_val
      FROM table_1 t1
      INNER JOIN table_2 t2 ON (t2.key_2 = t1.key_2)
      LEFT JOIN table_3 t3
      ON (t3.key_3b = t2.key_3b and t3.key_3a = t1.key_3a)
    SET value_1 = new_val;And again the same restrictions regarding key-preserved tables apply as described in the post referred to.

    The problem that you described is simple. The outer join duplicates all the rows from the parent table (complaint). If you want to sum a column from the parent table, then this sum includes all the duplicated rows.
    There are several solutions for this problem.
    A) One had been shown already by Cenutil. Instead of doing an outer join, you can do a subquery in the select clause that delivers the additional information from the detail table.
    SQL> select reason,
       sum(total),
       sum((select count(*) from complaintroll cr where c.cno=cr.cno)) cnt_rolls
    from complaint c
    group by c.reason;
    REASON          SUM(TOTAL)  CNT_ROLLS
    crea                   400          0
    brst                   300          0
    edge                   500          5b) sum in two steps. First sum and count including the join criteria, then use this information to calculate the correct total sum.
    SQL> select reason, sum(stotal), sum(stotal/scount), sum(scount), sum(cnt_rolls)
      2  from (select reason, sum(total) stotal, count(*) scount, count(cr.cno) cnt_rolls
      3         from complaint c
      4         left join complaintroll cr on c.cno=cr.cno
      5         group by reason, c.cno
      6         )
      7   group by reason;
    REASON          SUM(STOTAL) SUM(STOTAL/SCOUNT) SUM(SCOUNT) SUM(CNT_ROLLS)
    crea                    400                400           1              0
    brst                    300                300           1              0
    edge                   1250                500           5              5
    sql> c) another option is to do the left join, but do the aggregation only one time for the parent table. Analytic functions are helpful for that. However since analytic fuinctions can't be used inside an aggregation function, we would again need an inline view.

  • How to use common object from two tables with out join.

    HI,
    I have two tables called A & B In A table i have the following objects
    1.weekend
    2.S1(measure)
    3.S2(measure)
    4.S3(measure)
    5.S4(measure)
    And In B table i have followning columns
    1.week end
    2.p1(measure)
    3.p2(measure)
    4.p3(measure)
    5.p4(measure)
    Now in universe i created all the measure objects i.e.s1,s2,s3,s4,p1,p2,p3,p4 A.weekend,B.weekend.
    instead of using week end two times i wnt to use only once because this is common in both table.
    if i use join between these tables i am getting values fine
    But With out join is there any thing to do in universe level to create common objects to use from both the tables..I tried using aggregate awareness but while reporting it is taking as two SQL.which is not synchronized.
    Please help me on this ...

    hi,
    Although  Weekend column is present in both tables, by creating a single Object in Universe, Universe can identify relationship with only table referenced in Object Creation.
    So, there will be no identification of relationship with other table measures.
    Obviously, you need to create 2 Weekend objects in Universe (in two classes).
    Case 1: You need not join these two tables in Universe. When you create 2 Queries in WEBI, automatcially Weekend objects are synchronized (if both are of same datatype)
    Case 2: If you join these two tables in Universe, Obviously,
    your SQL may contain Weekend from Table1, measures from Table 2
    or
    your SQL may contain Weekend from Table2, measures from Table 1
    Finally, You need to create 2 objects in Universe. But your query may contain a single Object based on Case 2.

    The previous query gives 4 records less.
    Does Oracle support outer joins with out subquerys in the from clause or i am doing some thing wrong here(I mean syntax error)
    DO I need to write subqueries for every outer join to get the correct record.
    If I do outer joins with one or two tables with out subqueries.....I do not have any problem
    Thanks

    There are two issues. First Oracle supports outer joins against one table. This means you can do this:
    where a.col1 = b.col1(+)
    and a.col2 = c.col2(+)
    and a.col3 = d.col3(+)
    but you can't do this:
    where a.col1 = b.col1(+)
    and b.col2 = c.col2(+)
    because this outer joins to more than one table.
    The second issue is that you must outer join to all columns of a table. So you can't do this:
    where a.col1 = b.col1(+)
    and b.col2 is null
    but you can do this:
    where a.col1 = b.col1(+)
    and 'X' = nvl( b.col2(+), 'X' )
    null

  • How to poll a blob using db adapter, with outer joins condition

    Hi All,
    We are trying to poll tables which contain column types as long and blob, we are using relationships in adapter and kept outer joins. by this we got select distinct t1.document .....etc
    distinct keyword cannot be used for blobs.
    is there any way to poll these tables having blob column types with outer joins.
    thanks a lot in advance,
    RR

    Hi,
    Procedure will be an explicit Invoke not Polling. If you can alter you design such that your BPEL process instead of polling gets triggered by some external entity (Java, PL/SQL, Scheduler, another BPEL etc.), you can put the data fetching logic in the procedure and call this procedure from your BPEL process to get the data. And your BPEL process is called periodically at an interval by an external entity.
    Also see if you can restrict the duplicate records at the database level itself. Polling, AFAIK, is limited in terms of customization and wouldn't be easy to customize. However, would like to learn a way if someone has.

  • Generate a where clause with outer join criteria condition: (+)=

    Hi,
    In my search page, I use Auto Customization Criteria mode, and I build where clause by using get Criteria():
    public void initSrpQuery(Dictionary[] dic, String userName) {
    int dicSize = dic.length;
    StringBuffer whereClause = new StringBuffer(100);
    Vector parameters = new Vector(5);
    int clauseCount = 0;
    int bindCount = 1;
    for(int i=0; i < dicSize; i++){
    String itemName = (String)(dic.get(OAViewObject.CRITERIA_ITEM_NAME));
    Object value = dic[i].get(OAViewObject.CRITERIA_VALUE);
    String joinCondition = (String)dic[i].get(OAViewObject.CRITERIA_JOIN_CONDITION);
    String criteriaCondition = (String)dic[i].get(OAViewObject.CRITERIA_CONDITION);
    String criteriaDataType = (String)dic[i].get(OAViewObject.CRITERIA_DATATYPE);
    String viewAttributename = (String)dic[i].get(OAViewObject.CRITERIA_VIEW_ATTRIBUTE_NAME);
    String columnName = findAttributeDef(viewAttributename).getColumnNameForQuery();
    if((value != null) /*&& (!("".equals((String).trim())))*/){
    if(clauseCount > 0){
    whereClause.append(" AND ");
    whereClause.append(columnName + " " + criteriaCondition + " :");
    whereClause.append(++bindCount);
    parameters.addElement(value);
    clauseCount++;
    If I want to generate following where clause:
    select
    ,emp.name
    ,emp.email
    ,emp.salesrep_number
    ,comp.name
    ,gs.srp_goal_header_id
    ,gs.status_code
    ,gs.start_date
    ,gs.end_date
    from g2c_goal_shr_emp_assignments_v emp
    ,jtf_rs_salesreps rs
    ,xxg2c_srp_goal_headers_all gs
    ,cn_comp_plans_all comp
    where 1 = 1
    and rs.salesrep_id = gs.salesrep_id (+)
    and gs.comp_plan_id = comp.comp_plan_id (+)
    and gs.period_year (+) = :1 -- :1 p_fiscal_year
    How can I generate a where clause with outer join : gs.period_year (+) = :1 ? Will I get '(+)=' from get(OAViewObject.CRITERIA_CONDITION)?
    thanks
    Lei

    If you are using SQL-Plus or Reports you can use lexical parameters like:
    SELECT * FROM emp &condition;
    When you run the query it will ask for value of condition and you can enter what every you want. Here is a really fun query:
    SELECT &columns FROM &tables &condition;
    But if you are using Forms. Then you have to change the condition by SET_BLOCK_PROPERTY.
    Best of luck!

  • Oracle.jbo.RowAlreadyDeletedException with outer join

    Hi,
    I have created a VO, based on an EO, with an outer join present.
    The first time I query my data (search) everything goes well, but when I perform a search the second time, I receive the error message: "oracle.apps.fnd.framework.OAException: oracle.jbo.RowAlreadyDeletedException: JBO-25019: Entiteitsrij van sleutel oracle.jbo.Key[202 53162 ] not found in XxpostMmpParametersEO."
    The reason why is because of the outer join there is no 1 to 1 relationship between the EO and the VO. However for the first time , it works fine.
    Does someone have an idea how I can avoid the error for my second search action?
    Thanks in advance!
