Query/right join/

query/right join/
Ultimately we are trying to find the ZZOMTAB.STAFF
I know the value exist because I have queried this by
K_NO
By this query
Select
ZZOMTAB.STAFF
from
ZZOMTAB
where
K_NO = 146735
so it is there
but what I am supplied with is app_no=79219
I have tried this query and it does not work ( no value in the ZZOMTAB.STAFF)
SELECT
     ZZOMTAB.STAFF
FROM TKASERTAB
          RIGHT JOIN ZZOMTAB
          ON TKASERTAB.K_NO = ZZOMTAB.K_NO
          RIGHT JOIN APPTAB
          ON TKASERTAB.app_no= APPTAB.app_no
          where
          APPTAB.app_no=79219
the value that I am trying to get is in ZZOMTAB.STAFF
and I am given with app_no=79219
the tables are
tables are
TKASERTAB with columns K_NO and APPNO
APPTAB with column APPNO
and
ZZOMTAB with K_NO
I am trying to get the value of ZZOMTAB.STAFF
Can someone help??
Thanks in adv

SQL statement that includes LEFT & RIGHT JOIN in the same statement??? Help

Hi,
How an I write an SQL statement with a GROUP BY that will both (a) include the NULL value from the left hand table, but also (b) include ALL columns from the right hand table. It's like I need a LEFT JOIN and a RIGHT JOIN in the query at the same time.
Here's an example of the 2 tables I have and the result I'm after. As you can see I want the NULL's from Expenses Table summed, as well as include all categories from the right hand table (i.e. even if there are no expenses against them)
Table = Expenses
Amount Category
$10 1
$20 2
$30 1
$40 NULL {i.e. not yet categorised}
Table = Categories
ID Title
1 Food
2 Entertainment
3 Travel
4 Personal
REQUIRED RESULT
Category Total
Food 40
Entertainment 20
Travel 0
Personal 0
NULL 40
Thanks

Why Left and Right Joins if only one of them can serve the same purpose?

I understand that left join is used to display all the records from left table whereas the right join is used to display all the records from right table in a join.
However, if we switch the positions of the join tables and perform left join we can get all the records of the left table.
A left join B -> will give all records from A
A right join B ->will give all records from B
B left join A -> will again give all records from B.
The order in which the data is displayed(ie the field order) can also be maintained in the SELECT clause.
So, Why do we have left and right joins separately in existance, when only one of them can serve the same purpose?

Hi,
I think it's because it is sometime more natural to outer join on left or right.
In your data model (or the query you are writing), there is some kind of hierarchy between tables : I feel more natural to have the table with lowest hierarchical level (the root table) on the left. So I sometimes prefer to right outer join...
This is a very personal feeling, I must admit.
To me what is strange is to have chosen left and right as they refer to a "latin" reading direction => forward join and backward join would be more meaningful for people that read from right to left.
+And I prefer the new joining syntax that doesn't us the {noformat}(+){noformat} sign...+

How to do inner join ,outer join, left join ,right join by using infoset

how to do inner join ,outer join, left join ,right join by using infoset

Hi
If you want to make join ,outer join, left join ,right join then its possible if you are using ODS or direct infoobject (In BW3.5) and if you are using BI7.0 then you also make join ,outer join, left join ,right join with Cube also.
For making join ,outer join, left join ,right join in infosets you just select your info provider then right click on your infoarea from context menu select info set after doing this one pop-up opens here u define your infoset technical name and give either ODS object name of infoobject name.
After doing this next screen opens in right hand side your selectes ODS or infoobject shows in graphical format .
and left hand side it shows one menu bar here you can select another ODS or infoobject for making join ,outer join, left join ,right join .just click on ODS button in menu bar and select ODS drag your selected ODS from Left to right after doing this your selected ODS shown in right hand side window in graphical format you just now after doing this you are able to make join ,outer join, left join ,right join for this first you select field from one ods and drag a line from 1 ods to second ods after doing this one arrow is created from one ods to another ods just right click on arrow and make join ,outer join, left join ,right join in to your ODS.

How to build a query to join on two tables without mapping

I did Automatic mapping by the workbench Directofield mapping with the table and java object.
Wanted to build a simple join query by joining on the same field on both the tables.Not the sql query through the toplink using expression builder.
Please help.............
Spent one full day for this................

Thanks Don for the reply,sorry to bug you,but i need help.....
SELECT A.AGNCY_C,
     A.TYPE_C,
     A.RESN_C,
     A.S_TYPE_C,
     A.SUB_ID_C,
     A.RY_C
FROM RATING A, REF B
WHERE A.ID_C = B._ID_C
AND A.ALPHA_C = B.ALPHA_C
AND A.EFF_D >= B.MATURITY_D
This is the real query i was talking about.I did mapping automatically through the workbench,generated java classes also throught the workbench.
Now they don't want to execute the raw sql.They wanted to get all the RATING objects with the where condition.
So how to build a query by using toplink.
tried your example
ExpressionBuilder builder = new ExpressionBuilder();
Expression creditRating = builder.getTable("RATING").getField("ID_C");
Expression issue_ref = builder.getTable("REF").getField("ID_C");
Expression join = creditRating.equal(issue_ref);
I am getting java.lang.OutOfMemoryError
error.
I selected the option generate classes and descriptors
from the tables (RATING,REF).,so it created the classes and dscriptors automatically.
In Database script for the table RATING like this
ALTER TABLE RATING ADD (
CONSTRAINT RATING_F1 FOREIGN KEY (ID_C, ALPHA_C)
REFERENCES REF (ID_C,ALPHA_C));
I think when i generate descriptor automatically it is keeping this association.
Please help me.........

Query to join 2 tables by interval of value

Hi all
I need your help in creating a query to join 2 tables by interval of values.
The thing i want to d ois like this: i have 2 tables the first one containing list of serial number and the secon is containing interval of serial number (startnumber and end number) and other information like the user creating the serial number.
I want to list all serial numbers from the first table and the user creating each serial number from the second one if the serial number is between each interval of the second table.
here is an example>
SQL> create table test1 (code varchar2(1), serial number);
Table created.
SQL> create table test2 (requester varchar2(10),startno number, endno number);
Table created.
SQL> insert into test1 values('A',1);
1 row created.
SQL> insert into test1 values('B',3);
1 row created.
SQL> insert into test1 values('C',8);
1 row created.
SQL> insert into test1 values('D',12);
1 row created.
SQL> insert into test1 values('E',20);
1 row created.
SQL> commit;
Commit complete.
SQL> insert into test2 values('TATA',1,5);
1 row created.
SQL> insert into test2 values('TOTO',6,10);
1 row created.

B          TATA
C          TOTO

select code,
        requester
from test1,
        test2
where serial between startno(+) and endno(+)
order by code
C REQUESTER
A TATA

SQL query -- self-join question?

10065 10006 18302650166 16416609306
looking at the above query, i am just performing a simple select from one of my tables. Now i require the carriername for both originator and destination columns, and the names for these are found on another table carrier.
so, i am re-write the above query as: (join with carrier table)
SQL>
SQL> select originator,destination,oaddress,daddress,carriername from (select * from activity,carrier where originator=carrier_code and rownum<=3);

Now, i got the carrier name for my originator, how would i find the carriername for my destination also (in the same query). One way of doing it is joining the carrier table twice, but is there any other better approach.
Hope i am clear, any help will be greatly appreciated. Thanks.

Translate JOIN syntax from LEFT JOIN, RIGHT JOIN to (+)

I have looked through a lot of documentation, but have yet to see some concreate examples of how to code a JOIN when you are used to LEFT, RIGHT JOIN, etc.
Could someone translate these, removing the LEFT OUTER JOIN, etc. and replace with the (+). I am fairly new to Oracle and have been using the others all along?
SELECT *
FROM LOCATION L
LEFT OUTER JOIN DEPT D
ON (L.LocationID = D.LocationID)
LEFT OUTER JOIN EMPLOYEE E
ON (D.DeptID = E.DeptID);
SELECT *
FROM EMPLOYEE E
RIGHT OUTER JOIN DEPT D
ON (D.DeptID = E.DeptID)
RIGHT OUTER JOIN LOCATION L
ON (L.LocationID = D.LocationID);
SELECT *
FROM LOCATION L
FULL JOIN DEPT D
ON (L.LocationID = D.LocationID)
FULL JOIN EMPLOYEE E
ON (D.DeptID = E.DeptID);
Thank you.

right outer join table_b b
on                b.user_id = a.user_idI'm not sure about the full join.
Edit:
Ah, yes, I remember. The only way to do a full outer join with Oracle syntax (that I'm aware of) is to use UNION:
select b.*
from    table_a a
,       table_b b
where   a.user_id(+) = b.userid;
union
select b.*
from    table_a a
,       table_b b
where   a.user_id = b.userid(+);

2 right joins - how to add another right join to this statement?

Hi all,
I had to upgrade my sql statement and add another column. my previuos sql was:
          SELECT TR.ID, TA.Name, TR.idTarget, TR.Controller_Status, TR.previuosYear, TR.deduction, TR.idProduction, SUM(CSV.cur_amount) AS Accumulated,    PD.Name AS PName, PD.type_2, CL.ToRange AS growth
          FROM agent AS TA, production_name AS PD, calculation AS CL, target AS TR
          RIGHT JOIN csv_production AS CSV ON CSV.ID=TR.ID AND CSV.Production_Date BETWEEN '2006-10-01' AND '2006-12-31'
          WHERE TA.ID=TR.ID
          AND PD.idProduction = TR.idProduction
          AND CL.idCalculation = ANY (SELECT MIN(idCalculation) FROM calculation GROUP BY idProduction)
          AND TR.idProduction=CL.idProduction
          AND TR.startDate= '2006-10-01' AND TR.endDate='2006-12-31'
          GROUP BY CSV.IDI had to add this line:
RIGHT JOIN csv_net_production AS CSV_net ON CSV_net.IATA=TR.IATA AND CSV_net.Production_Date BETWEEN '2006-10-01' AND '2006-12-31' my end result looks like this:
          SELECT TR.ID, TA.Name, TR.idTarget, TR.Controller_Status, TR.previuosYear, TR.deduction, TR.idProduction, SUM(CSV.cur_amount) AS Accumulated, SUM(CSV_net.cur_amount) AS net_Accumulated, PD.Name AS PName, PD.type_2, CL.ToRange AS growth
          FROM agent AS TA, production_name AS PD, calculation AS CL, target AS TR
          RIGHT JOIN csv_production AS CSV ON CSV.ID=TR.ID AND CSV.Production_Date BETWEEN '2006-10-01' AND '2006-12-31'
                           RIGHT JOIN csv_net_production AS CSV_net ON CSV_net.ID=TR.ID AND CSV_net.Production_Date BETWEEN '2006-10-01' AND '2006-12-31'
          WHERE TA.ID=TR.ID
          AND PD.idProduction = TR.idProduction
          AND CL.idCalculation = ANY (SELECT MIN(idCalculation) FROM calculation GROUP BY idProduction)
          AND TR.idProduction=CL.idProduction
          AND TR.startDate= '2006-10-01' AND TR.endDate='2006-12-31'
          GROUP BY CSV.IDBUT!!! the accumulated (Accumulated, net_Accumulated,) is multiplied by 3, which means that I must add another WHERE statement (i think?!)
thanks for any pointers

how do u relate csv_production ,csv_net_production ?
the one comparison i viewed is TR.ID against the IDs of these 2 tables
I mean
is there any relationship between these 2 tables?
specifically
is there any referencial integrity or like constraint exists between these 2 tables?
if so u can write a where condition csv_production.ID=csv_net_production.ID

     Select single VbrkBukrs VbrkKunrg    Vbrk~Vbeln
                   VbrkFkdat VbrkBstnk_Vf Vbrk~Zterm
                   Tvzbt~Vtext
                   VbakVbeln VbakBstdk
                   LikpVbeln Likplfdat    Likp~Lfuhr
       into w_vbrk
       from vbrk
      inner join       Tvzbt on TvzbtZterm        = VbrkZterm      and
                                Tvzbt~Spras        = sy-langu
      Inner join       Vbfa as SalesLnk
                             on SalesLnk~vbeln     = pu_vbeln        and
                                SalesLnk~vbtyp_v   = c_order
            inner join Vbak on VbakVbeln           = SalesLnkVbelv
      Inner join       Vbfa as DeliveryLnk
                             on DeliveryLnk~vbeln   = pu_vbeln       and
                                DeliveryLnk~vbtyp_v = c_Delivery
            inner join Likp on LikpVbeln          = DeliveryLnkVbelv
      where vbrk~vbeln = pu_Vbeln.
This code locates sales, delivery and payment terms info from a billing document number.
or
Here, this one also works fine :
select zfpcdcadivi zfpcdproforma zfpcdfactura zfpcdaniofactura
zfpcdmontousd zfpcdmontoap zfpcdebeln zfpcdinco1
zfpcdlifnr lfa1name1 zcdvsstatus zfpcdconint
into it_lista
from zfpcd inner join zcdvs
on zfpcdebeln = zcdvsebeln
and zfpcdproforma = zcdvsproforma
and zfpcdlifnr = zcdvslifnr
inner join lfa1
on zfpcdlifnr = lfa1lifnr
where zcdvs~status = '04'.
Also Here is another solution that just uses inner joins:
SELECT vbakvbeln vbfaerdat INTO (itab-vbeln, itab-wadat)
FROM ( vbak INNER JOIN vbap
ON vbapvbeln = vbakvbeln )
INNER JOIN vbfa ON vbakvbeln = vbfavbelv
WHERE vbak~kunnr = m_wm AND
vbak~vbtyp = 'C' AND
vbfa~erdat IN s_date AND
vbap~matnr = 'MZ1807F' AND
vbfaposnv = vbapposnr AND
vbfa~vbtyp_n = 'J'.

Who to query and join nested elements

I have a table that contains a XMLTYPE Field. How do I query and join nested elements. For example I have a schema that has a PerstrenList element that holds one or more Perstren nodes. The Perstren node will contain a RemarksList node that can contain one or more Remarks nodes. My goal is to query all of the Remarks and join them with the information in it's parent node. Without the parent node information the remark is meaningless. Following is a example document and desire result set. I know how to query the Perstren or the Remarks I just can not figure out how to marry the two. The query should only return the remarks joined with the parent information.
<RasDataSet>
   <PerstrenList>
        <Perstren>
           <TPERS>A</TPERS>
           <DEPLY>B</DEPLY>
           <STRUC>5</STRUC>
           <RemarksList>
               <REMARK>
                    <LABEL>ABC</LABEL>
                    <GENTEXT>Hello world</GENTEXT>
               </REMARK>
               <REMARK>
                    <LABEL>XYZ</LABEL>
                    <GENTEXT>Oracle XML</GENTEXT>
               </REMARK>
           <RemarksList>
        </Perstren>
        <Perstren>
       <TPERS>C</TPERS>
       <DEPLY>D</DEPLY>
       <STRUC>4</STRUC>
       <RemarksList>
           <REMARK>
                <LABEL>EFG</LABEL>
                <GENTEXT>Database</GENTEXT>
           </REMARK>
       <RemarksList>
        </Perstren>
        <Perstren>
       <TPERS>E</TPERS>
