Inner join-select -primary key in table issue

Hi ,
Iam using FEBKO(header) and FEBEP(item) in inner join select .But the datas fetching by this selct in not correct.The analysis is the is no common primary fields in the both table.
Question 1-> Can i use inner join without common primary key in the both tables, weather it possible to make a select without common primary key in both table. Please kindly let me know.
Question 2-> What is the other possible way to give the selct for both table(better performance)
Regards,
Veera

Hi,
When you use INNER JOIN in this case, link your tables based on KUKEY and ESNUM fields, bcoz there can be many items under a single header. So this will work for you, even from the performance point of view.
Hope this is helpful to you. If you need further information, revert back.
Reward all the helpful answers.

Something like the statement below? (It works in a simple select statement but not in an inner join)
SELECT *
 INTO CORRESPONDING FIELDS OF <t_itab>
 FROM <Dynamic table name> INNER JOIN pa0050 ON
 ( <Dynamic table name>pernr = pa0050pernr )
 WHERE <Dynamic table name>~pernr = it_pernr-l_pernr
 AND pa0050~bdegr = f_bdegr.
Any help would be apprecited very much.

ORA-02266: unique/primary keys in table referenced by enabled foreign keys

Hi,
I am trying to delete data from a table by dropping a partition. I have identified all the child tables by running the following command.
select 'select count(*) from '||table_name||' where employee_id = 100;'
from dba_constraints
where constraint_type='R'
and r_constraint_name in
(select constraint_name from dba_constraints
where constraint_type in ('P','U') and table_name='EMPLOYEE);
'SELECTCOUNT(*)FROM'||TABLE_NAME||'WHEREEMPLOYEE_ID_ID=100;'
select count(*) from PT_ORDERS where employee_id = 100;
select count(*) from PT_DEP where employee_id = 100;
select count(*) from PT_SKILLSET where employee_id = 100;
I dropped the partition for employee_id 100 in all of the child tables. The select count(*) returns 0 rows for each of the above.
When I try to run the below command on the EMPLOYEE table, I get 'ORA-02266: unique/primary keys in table referenced by enabled foreign keys'.
alter table EMPLOYEE drop partition EMP_ID_100;
I cant see why I am unable to drop this partition now as there is now child data in any of the referenced tables. Any suggestions or help on this would be greatly appreciated.
Thanks.

Rob

You should disable foreign key constraints first and drop partition. Deletion of rows or dropping partitions in childs don't work in this case
as you have the global dependency:

I guess you should consider such option as Referencial partitioning (with some restrictions).

Add a primary key to table.

Hello everybody,
I want to add a primary key to a table but it doesn't work.
select count(*), count(id) from tableA;
COUNT(*) COUNT(ID)
830447 830447
You see: The number of ids is equal to the number of rows. The ID is not marked as unique but it should be unique. I try to set id as the primary key:
alter table tableA add constraint "pk_constraint" PRIMARY KEY (id);
But I a get an error message: ORA-02437: cannot validate (pk_constraint) - primary key violated.
What is the problem?
I use Oracle 11g.

Populate choice component with 2 primary key in table

There are 2 primary key in table. When I create my uix with jheadstart, the UIXs don't populate choice component. How can I create automatically populate choice component, with 2 PK in table?

A choice component can only have one value attribute. So if you have a composite primary key in the table you use to populate the choice, it will not work correctly, because based on this single attribute the choice cannot render the correct row as selected.

Issues while changing primary key in table

Hi
I have one table. In that two fields are primary key. I want to change the second PK as FK only. But when i am changing this field as FK. Its showing one error 'Primary Key Change not permitted for value Table ZCAUSECATMASTER' . How to avoid this error.
Please help me.

Hi.....
Remove that primary key for the second field and assign your foregin key..table to that filed.....
So when you give entries in that second filed it will be validated with its foregin key table......its nothing but check table...
what all values in the foregin table only can given.....

Inner Join Select query

hello all,
Below is a inner join query
    SELECT aebeln aebelp apackno bzekkn b~ps_psp_pnr
                 FROM ( ( ekpo AS a INNER JOIN ekkn AS b
                          ON aebeln = bebeln
                          AND aebelp = bebelp )
                         INNER JOIN prps AS c
                          ON bps_psp_pnr = cpspnr )
                 INTO TABLE t_wbspo
                  WHERE a~ebeln IN s_ebeln
                   AND c~psphi IN s_psphi
                   AND stufe = c_task.
I want to modify this select and put one more join on ekkn-aufnr
and aufk-afunr .
Now for this i write the below code
SELECT aebeln aebelp apackno bzekkn bps_psp_pnr baufnr
           FROM ( ( ( ekpo AS a INNER JOIN ekkn AS b
                    ON aebeln = bebeln
                    AND aebelp = bebelp )
                   INNER JOIN prps AS c
                    ON bps_psp_pnr = cpspnr )
                    INNER JOIN aufk AS d
                    ON baufnr = daufnr )
           INTO TABLE t_wbspo
            WHERE a~ebeln IN s_ebeln
             AND c~psphi IN s_psphi
             AND d~aufnr IN s_aufnr
    AND stufe = c_task.
By the above way does it puts a join on ekkn-aufnr and aufk-aufnr ?
Is the above way the right way to do it ?
Please confirm

How to create tabular form whithout primary key in table

Hi All,
I have requirement to create a tabular form but the problem is, the table which I am using in the application don't have any Primary key, I am using only one table can't change any thing in table.(i.e can't add any row in table,no change in data model)
How can I create tabular form when primary key is not available.
looking forward for all of your quick responce.
Thanks in advance.
Dikshit Kumar Nidhi

You can create a view like
select a.rowid id, a.*
from table a
and create a tabular form on this view. You can use
the new column ID as Primary key.Did you try to actually do this? I did at
http://htmldb.oracle.com/pls/otn/f?p=24317:159
And when I change something and click Submit, I get an error
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-01733: virtual column not allowed here, update "VIKASA"."NO_PK_VW" set "ID" = :b1, "I" = :b2, "J" = :b3 where "ID" = :p_pk_col

Inner join select

I had my data declaration as below.
DATA :BEGIN OF t_plaf OCCURS 0,
 normt LIKE mara-normt,
 matnr LIKE plaf-matnr,
 pwwrk LIKE plaf-pwwrk,
 paart LIKE plaf-paart,
 verid LIKE plaf-verid,
 auffx LIKE plaf-auffx,
 psttr LIKE plaf-psttr,
 gsmng LIKE plaf-gsmng,
 END OF t_plaf.
corresponding inner join statement
SELECT maranormt plafmatnr
 plafpwwrk plafpaart plaf~verid
 plafauffx plafpsttr plaf~gsmng
 INTO TABLE t_plaf
 FROM plaf
 INNER JOIN mara
 ON plafmatnr EQ maramatnr
 WHERE plaf~paart = 'LA'.
Now I have changed the declaration as below
DATA : BEGIN OF t_plaf OCCURS 0,
 normt LIKE mara-normt.
 INCLUDE STRUCTURE plaf.
DATA : END OF t_plaf.
now i have changed the data declaration as mentioned above and need a inner join statement for the data declaration i have specified.
Any suggestions,
MAdhu

Hi Madhu,
USE INTO CORRESPONDING option instead of INTO TABLE.
SELECT maranormt plafmatnr
plafpwwrk plafpaart plaf~verid
plafauffx plafpsttr plaf~gsmng
INTO CORRESPONDING FIELDS OF TABLE t_plaf
FROM plaf
INNER JOIN mara
ON plafmatnr EQ maramatnr
WHERE plaf~paart = 'LA'.

How to add primary key for table with existing data?

The table is occupied data already. There was no primary key before, so for every column, there are some duplicate values.
I want to add a new column, which should be of the datatype integer, and can automatically increment, starting from 001. I tried this in Oracle SQL Developer, but it says "ORA-01758: table must be empty to add mandatory (NOT NULL) column". How can I do it? Thanks!

Hello, don't call the column ID, that could be an ID relating to anything. Perhaps be a little more specific like emp_id .
Then to update it:
UPDATE Employee emp
SET emp_id = (
SELECT row_num
 FROM (
SELECT ROWID,
 ROW_NUMBER() OVER (ORDER BY ROWID) row_num
 FROM Employee emp2) emp2
WHERE emp.ROWID = emp2.ROWID);That will assign a new EMP_ID for each, beginning at 1.
Then:
ALTER TABLE Employee MODIFY emp_id NOT NULL;
ALTER TABLE Employee ADD CONSTRAINT EMP_PK PRIMARY KEY (EMP_ID);Then create a sequence for future population of the Employee table:
CREATE SEQUENCE emp_seq START WITH <maximum value of emp_id + 1>;

Primary key for table

I have a table Gr_order which was populated ages ago and now it need to be populated
with some more look up data.
"Orderid" is primary key for the table but question is how do I insert "orderid" in insert statement in procedure. I could not find any sequence name. There are 1230
records which need to be inserted.
Desc Gr_order
Orderid Number Primary key
Desc Varchar2
INSERT INTO gr_order (orderid,desc)
VALUES (???, upper(each_pom.desc);Thanks
sandy

You find the code that inserts into the table and see if it uses the sequence ;-) . A sequence is not "attached" to a particular table - it is up to the inserting statement to decide if a sequence is to be used.
You might want to check if the table has a trigger - some developers like to emulate MS-sql server behaviour by having a trigger on the table that selects from a sequence. If it has such a trigger, then you just do your inserts without specifying order_id. But if the table does not have such a trigger, then you cannot know if the table was originally populated using a sequence or not (unless you can find the insert statements somewhere.)

How to use inner joins for 4 0r 5 tables

Hai Experts,
plz check my code, n plz help to inner join all the tables
TYPES : BEGIN OF ITAB,

and i got stucked here:

SELECT EKKO~EBELN

 INNER JOIN EKPO LFA1 T001W MAKT
 ON EKKOEBELN = EKPOEBELN
 EKKO~EBELN
 WHERE EKKO~EBELN IN S_EBELN.

hi Rajesh,
you have to join the tables one by one:
SELECT ekko~ebeln
 ekko~aedat
 ekpo~bprme
 ekpo~menge
 ekpo~werks
 ekpo~brtwr
 lfa1~lifnr
 lfa1~stras
 lfa1~name1
 lfa1~ort01
 lfa1~land1
 lfa1~pstlz
 makt~maktx
INTO TABLE itab
FROM ekko AS ekko
INNER JOIN ekpo AS ekpo
ON ekkoebeln EQ ekpoebeln
INNER JOIN lfa1 AS lfa1
ON ekkolifnr EQ lfa1lifnr
INNER JOIN t001w AS t001w
ON ekpowerks EQ t001wwerks
INNER JOIN makt AS makt
ON ekpomatnr EQ MAKTmatnr
WHERE ekko~ebeln IN s_ebeln.
This is the complete SELECT. BUT! The performance will be much better if you take out T001W and MAKT from the INNER JOIN. Do select on these tables in separate steps and merge the internal tables afterwards.
hope this helps
