How to do left outer join in one-one mapping

I tried to do a left outer join between two tables. I specified
kodo.jdbc.DBDictionary: JoinSyntax=sql92 in kodo.properties. I used
ref-join-type="outer" in the package.mapping. However, I still see Kodo is
translating my queries using inner join. How can I force kodo to use outer
join (or maybe even to use left outer join) when translating my queries?
Thanks.

Kodo will automatically use an outer join when eager-fetching a to-one
relation (unless you have set null-value="exception" on the field, in
which case Kodo knows it can use an inner join). There is no need to set
the ref-join type (in fact, that is only for when the foreign key
columns are in a joined table).
When you place criteria on a relation in a query, though, the relation
must exist to satisfy the query. For example, in the filter:
"relation.x == y"
The "relation" field must hold a related object to satisfy the
expression, just as in Java.
If you want the "relation" field to optionally be null, then write your
filter exactly as you would in Java:
"relation == null || relation.x == y"
Kodo will correctly use an outer join in this case because the filter
can be satisfied even when no related object exists.

  • How to use left outer join on more than one table (source)

    Hi all,
    In our project we are converting the Unix shell & SQL scripts into OWB mappings. We are facing problem converting left outer join in OWB. here is one of the example. i have just pasted the FROM and where condition.
    FROM ym_scr t1, branch_finmonth t3
    LEFT OUTER JOIN item_image t2
    ON (t1.branch_no = t2.branch_no
    AND t1.item_no = t2.item_no
    AND t3.to_date between t2.tran_dt and t2.to_dt
    AND t2.to_dt >= '$start_images' ) <<<========= '$start_images' THIS COMES FROM THE UNIX VARAIBLE ,
    We converts the same when we are putting it in OWB join Operator
    INGRP1.branch_no = INGRP2.branch_no(+)
    AND INGRP1.item_no = INGRP2.item_no(+)
    AND INGRP3.to_date between t2.tran_dt and t2.to_dt
    AND INGRP2.to_dt >= INGRP2.start_images
    But as you see in the OWB opreator we can put left join with INGRP1 with INGRP2.
    We can not make same join with INGRP3 & INGRP4 , becoz it failed saying "you cannot left outer join on more than one table/source".
    so overall this OWB code makes incomplete left outer join as per the above ANSI SQL join in Oracle.
    Bcoz of the problem we are getting less number of rows...........
    SO please please help me on this
    Regards
    Ashok

    Hi.
    I know this topic is here for a while now, but I had the same problem today, searched for help and didn´t find anything.
    Later I figured out how to do this.
    You just have to put the (+) one time, and the OWB converts in an LEFT OUTER JOIN statement.
    For this case, all you have to do is:
    ( INGRP1.branch_no = INGRP2.branch_no(+) AND INGRP1.item_no = INGRP2.item_no AND INGRP2.to_dt >= INGRP2.start_images )

  • How to Specify Left Outer Join in OWB

    If I run the query:
    select s.school_id,
    nvl(max(decode(cv.cat_id, 'UCL', cv.long_desc, null)),'Unknown') UCL,
    nvl(max(decode(cv.cat_id, 'REGION', cv.long_desc, null)),'Unknown') REGION,
    nvl(max(decode(cv.cat_id, 'TREASREG', cv.long_desc, null)),'Unknown') TREASREG,

    nvl(max(decode(cv.cat_id, 'PCAP', cv.long_desc, null)),'Unknown') PCAP,
    nvl(max(decode(cv.cat_id, 'ATSIC', cv.long_desc, null)),'Unknown') ATSIC
    from sdw.sdr_schools s
    left outer join
    sdw.sdr_school_category_values scv on s.school_id = scv.school_id
    left outer join
    sdw.sdr_category_values cv on cv.cat_id = scv.cat_id
    and cv.cat_value_id = scv.cat_value_id
    group by s.school_id
    order by s.school_id
    I get 1706 records. In OWB I get 1656 records.
    In OWB I use a JOIN for the three tables, then an expression for the decode lines and sort and then the final table. In the SQL above, if the second left outer join is removed I get 1656 records?
    Ho do you force OWB to produce 1706 records?

    You have to use the (+) notation.
    e.g.
    table1.column1 (+) = table2.column1
    Also, you can do a full-outer-join using table1.column1 (+) = table2.column1 (+) even though this is not legal SQL*Plus syntax.

  • Left outer join (business model and mapping layer)

    hi, experts!
    !http://img693.imageshack.us/img693/9642/joinp.png!
    if there are a dimension table and a fact table, I wanna have a left join from dimension to fact (select * from dimension a left outer join fact b on a.key = b.key;)
    is the selection for cardinality correct?
    And I only change TYPE to "Left Outer" ?
    however, I tested on this setting.
    if I only select the dimension , 15xx records returned.
    if I select the dimension and fact, 14xx records returned.
    any wrong setting ?

    Just to make I'm getting your situation correct, are the following true:
    --you've got a total of 15 records in your dimension table
    --you want to see every dimension record, regardless if there is any fact records that have that dimension
    --if a fact record exists, it must have one of the 15 values in your dimension table.
    --a single dimension record can match to multiple fact records
    If those statements are true, then you want your dimension cardinality set to 1 and your fact cardinality set to N.
    Then you'll want to do the left outer join like you mentioned and you should be set.

  • How to use "left outer join" in SQVI

    Dear ALL ,
    I want to match MARA materials with BOM material table (MAST,STPO)material or Routing material table (MAPL,PLPO) and I want the list of NONMATCHING material codes from SQVI.
    How to get these items which do not match in 2 tables........?
    I have to work with SQVI + EXCEL ( VLOOKUP ) in excel sheet.
    Thanks...

    Kishore,
    After selecting the table join option, In layout mode enter the table names in Joined tables tab. Select the 2 tables using check boxex and select the join type like left inner and click on define condition. This would create a left inner join. Similarly carry out for the next 2 tables.
    Hope it is useful. If so reward your points.

  • Left outer join using anyOfAllowingNone

    Hi,
    I'm trying to join two tables (tableA and tableB) with left outer join using anyOfAllowingNone (One to many relationship) and try to fetch the tableB data with some constraint on it.
    But the sql generated out of the expression builder is not a proper left join, it actually forms a inner join, which brings only table A data which satisfies all the condition. Actually I want all of tableA data and for every record from tableA I want the data from TableB which matches the key from tableA to tableB and some condition applied on tableB data.
    I guess I'm doing some thing wrong, I went through the document and sample but still its not getting me the right data.
    Below is my expression builder:
    exp = builder.get("tableA_K").equal(some value);
    exp = exp.and(builder.get("effectiveIn").toChar("MM/dd/yyyy").lessThanEqual(date));
    exp = exp.and(builder.get("effectiveOut").toChar("MM/dd/yyyy").greaterThanEqual(date));
    exp1 = builder.anyOfAllowingNone("tableBCollectionAttribute").get("effectiveIn").toChar("MM/dd/yyyy").lessThanEqual(date);
    exp1 = exp1.and(builder.anyOfAllowingNone("tableBCollectionAttribute").get("effectiveOut").toChar("MM/dd/yyyy").greaterThanEqual(date));
    return exp.and(exp1);
    Below is the sample query generated:
    select distinct tableA.all data
    where (((((tableA.key = 2219785)
    and (to_char(tableA.EFFECTIVE_IN_S, 'MM/dd/yyyy') <= '03/27/2008'))
    and (to_char(tableA.EFFECTIVE_OUT_S, 'MM/dd/yyyy') >= '03/27/2008'))
    and ((to_char(tableB.EFFECTIVE_IN_S, 'MM/dd/yyyy') <= '03/27/2008')
    and (to_char(tableB.EFFECTIVE_OUT_S, 'MM/dd/yyyy') >= '03/27/2008')))
    and (tableB.key (+) = tableA.tableB_Key))

  • Could any one tell me how to do the left outer join or right outer join?

    Could any one  tell me how to do the left outer join or right outer join in Webi Rich Client? thanks.

    we can do it in two ways
    1.  In  web intelligence level  on the query panel click the sql query and write the statement what ever u want there by modifying the existing statement.
    2.  In universe level select the fields in the two tables that you want to make join and create the join between two tables directly by joining field in table 1 to the field in the table 2 by drawing a line and double click on the line to view the join properties,then on join properties if we check the table 1 outer then it is left outer join if we check on table 2 outer then it will be the right outer join.after exporting the universe to the central sever we are now ready to use in web intelligence with out being changed anything in the sql query.
    endorse me if it is useful.
    thanks & regards

  • How can we make consecutive left outer joins in Composite Provider?

    Hi,
    For the following design:
    Sales order and Delivery DSO's are unions on field Delivery Number.
    Invoice(Billing DSO) is having left outer join and joins with Sales Order DSO's based on the field Sales Order Number.
    Shipment DSO has left outer join, joins with Invoice DSO based on Delivery number.
    My doubt here in this composite provider design, is more than one consecutive left outer joins(in Invoice, shipment dso join) are allowed?
    Since this is possible in SAP ERP through writing abap codes, I came across that this kind of modelling is not possible in BW on  Hana through Composite provide kindly suggest how can we achieve this design in SAP BW On hana.

    HI Suresh,
    If the infoset is based on left outer join , you see the respective table shaded in a dirrerent colour and also displays
    that it is a left outer join in the connection
    refer the below link for the details on left outer join , you can make a join as left outer from the context menu of the

  • Left Outer Joining multiple tables to one source table FAILS with VLD-1511

    Hi all,
    Is it me, or is OWB unable to handle left outer joining 1 source table to multiple other tables?
    I want to load a fact table so I have 1 source table with measures. This table must be outer joined to some dimensions that have their FK in the fact table.
    The SQL statement would look like this (and is perfectly valid):
    select ...
    from input, dim1, dim2
    where input.c1 = dim1.c1(+)
    and input.c2 = dim2.c2(+);
    I put the where clause in the joiner operator and validate, but that gives me message VLD-1511: A table may be outer joined to at most one other table.
    Even splitting this up into one outer join per joiner still gives this message.
    A search and look around on the forum and on metalink shows there are related issues (like bug 3334035). Seemingly creating a view is the work-around to use.....? (ie downgrading owb to a simple gui tool) }-;
    Have other people experienced this problem of not being able to outer join one input table to multiple other tables?
    Thanks,
    Ed

    I have had some feedback from Oracle. It turns out this has to do with 2 issues. Below I have pasted the text that Support gave me:
    <---------- START QUOTE ---------->
    RESEARCH
    =========
    Bug 3437036 KEY LOOKUP DOES NOT DETECT ORA-1417 IN VALIDATE/GENERATE STEP
    Unpublished Bug 4211684 FORWARD PORT OF BUG 3437036
    shows:
    Some more development has been completed when this bug is fixed in Paris.
    The following are the details:
    1. If the join condition contains a full outer join such as
    tab1.c (+) = tab2.c (+) and tab2.c (+) = tab3.c
    then the new validations implemented for this bug do not apply since
    in OWB, full outer join triggers generation of joins in ANSI syntax.
    ANSI syntax does not have the original problem the base bug of this
    bug reported.
    2. If the join condition does not contain any full outer join condition,
    then the join is generated in Oracle join syntax, which is subject two
    several restrictions. The fix to this bug check two of the restrictions.
    3. The first restriction in Oracle syntax is that the outer join operator
    "(+)" can only directly be attached to a column name. If you attach it
    to an expression, such as the following:
    (tab1.c + 1) (+) = tab2.c
    Then there will be an ORA-936 error at the time of mapping deployment.
    For this case, I have added a validation message VLD-1512 to error out
    this situation.
    4. The second restriction in Oracle syntax is that a table can only be
    outer joined to exactly one other table.
    For example, this is an invalid join in Oracle syntax:
    tab1.c (+) = tab2.c and tab1.d (+) = tab3.d
    because tab1 is left outer joined to tab2 and tab3.
    But note that the following is still valid in Oracle syntax:
    tab1.c (+) = tab2.c and tab1.d = tab3.d (+)
    because tab1 is left outer joined to tab2 and right outer joined to tab3.
    So this latter case does not violate the restriction that "same oj" to
    more than 1 table is not allowed.
    If same oj to more than 1 table is specified in a join condition,
    VLD-1511 will be issued, and the map is made invalid.
    <---------- END QUOTE ---------->
    OWB does a partial validation, ie not all access paths are (can be) checked. A full check is only done by the database itself. So some scenarios (like checking whether multiple tables are outer joined the correct way) are not checked, and in this case are flagged with an error (even though it is actually a correct scenario).
    Seemingly this was not flagged with an error in earlier versions of OWB, so beware, OWB behaviour may change when upgrading...
    Alternative solutions are (1) using key lookups, (2) using a view with all outer joins in there, (3) using intermediate result tables between the joins.
    Hope this info helps some people prevent spending too much time on a false error message,
    Ed

  • How can I crate a view with tables which require "Left outer join"?

    Hi guys,
    how can I define a view with tables which require "Left outer join"?. In SE11 "View",->tab "Join condition", it seems that it valid only for "Inner Join".

    Hi
    Inner Join and Outer Join 
    The data that can be selected with a view depends primarily on whether the view implements an inner join or an outer join.
    With an inner join, you only get the records of the cross-product for which there is an entry in all tables used in the view.
    With an outer join, records are also selected for which there is no entry in some of the tables used in the view. (ABAP allows left outer join.)
    The data that can be selected with a view depends primarily on whether the view implements an inner join or an outer join.

  • How to change to a left outer join an Infoset that is already created?

    Hi! I need HELP please!!!
    I created a data model based on an Infoset, but at the time to report on WEBI, there is a field that is recognized as a text instead of a date. I've been trying to modify everything i think of but nothing worked!!!!!! So now i want to change my infoset to a left outer join but i can't find where.
    Could anyone help me, please!?
