I have a schema whereby a table is not joined with other tables.
the info on that table can be gotten manually (by doing a query) and then using that info in another query. so is there a way of getting info from that table?
I have the following, simplified, query involving 3 tables:
Table 1
ID---Student
1----Terry
2----Gilbert
3 ---Egbert
4 ---Norris
Table 2
ID--Base_ID--Base_Name
1 --F100 ------St. Vincents
3 --F102 ------AB Junior High
4 --F103 ------CD Middle School
Table 3
ID--Choice_order_ID--Secondary_Base_Choice
1---Co1-------------School A
1---Co2-------------School B
1---Co3-------------School C
2---Co1-------------School B
2---Co2-------------School A
2---Co3-------------(null)
3---Co1-------------School C
3---Co2-------------School A
3---Co3-------------School B
I use the following query:
select table1.student, table2.base_name
from table 1, table2,
where table1.id = table2.id (+)
which returns the student and the base name they attend, i.e.
Student---Base_Name
Terry-----St. Vincents
Gilbert----(null)
However, I need to also list their school Secondary_Base_Choices horizontally, in the following format,
I.e.
Student---Base_Name----Base_Choice_1---Base_Choice_2---Base_Choice_3
Terry-----St. Vincents----School A----------School B-----------School C
Gilbert----(NULL)---------'NO DATA'--------'NO DATA'----------'NO DATA'
Egbert----AB Junior H----School B----------School A-----------'NO DATA'
I use a table taht i call C where the value of a field ("Type") is always a concat of values coming from more than 2 tables (A et C)
select A.Numero, B.date, B.commentaire,C.Libelle
from A, B, C
where A.codeLibelle = C.codeLibelle
and CONCAT(A.Numero, CONCAT(A.DemNumero, C.Libelle)) = B.Type (+)
when i execute this statement, i obtain
ORA-01417: a table may be outer joined to at most one other table
I have another request where it works fine and where i have concat of fields from only a single table:
select A.Numero, B.date, B.commentaire,C.Libelle
from A, B
where CONCAT(A.Numero, A.DemNumero) = B.Type (+)
In the first request Oracle seems to not accept a join with more than 2 tables
SELECT *
FROM EMP E,DEPT D
WHERE D.DEPTNO = CASE WHEN COMM IS NULL THEN E.DEPTNO ELSE E.DEPTNO(+) END;
It is giving error on executing saying
ORA-01417 - a table may be outer joined to at most one other table.
Why it is giving this error,
How can i write such a query, since it my requirement
when i am writing dump from external table, it is accessing records from dump.but when i am trying to access other dumps(create thru expdp) it is giving error.the logic i am following is mentioned below-

i am able to see records.

But in my Insert statement, I am having get one of the column values from another table. How can I write my insert statement in such a way as to insert values contained in ':new' pseudo columns and a select from another table. Below is my insert statement in the trigger :
-------
IF (:old.GROUP_YELLOW <> :new.GROUP_YELLOW) THEN
INSERT INTO TEST.W_THRESHOLD_LOG
(THRESHOLD_LOG_WID, CHANGE_DATE, MEASURE_TYPE_WID, MEASURE_NAME, CUSTOMER_WID, CUSTOMER_NAME, USER_ID, CHANGED_ITEM, PREV_VALUE, NEW_VALUE)

END IF;

In the above code if the hardcoded value 'Customer1' need to be picked from another table,
i.e .

create or replace procedure test_prc as
v_test number(9);
begin
select product_id into v_test
from PRODUCT where rownum=1;

I am having 3 oracle 10.2.0.5 version standard edition databases running on windows platform on 3 different servers. OEM is configured for all the 3 databases and we are able to access these OEM from their respective servers.
As per my knowledge, I should be able to access the OEMs of all 3 databases from my local machine. But Iam facing problem in accessing the OEMs from my local machine.
what changes need to be done so that I can access the OEMs of all 3 databases from one single local machine rather than checking it by logging into their respective servers.
1.As we can create materialized view for accessing data from other schema but same database. will it be effective or it will act as a normal view.
2.Will materialized views can be created in Fast mode for the above scenario?

[ORA-3134: Connections to this server version are no longer supported.]
..using the drivers we used to use in XP and Server2003 to access a legacy Oracle7 db. Connections to this db are needed for typical CRUD functionality by multiple applications, some written in Classic ASP and some in C# .NET 3.5 & 4.0. I have tried ODBC drivers (System.Data.Odbc) and also ODP (Oracle.DataAccess.Client) to no avail.
Any existing driver solution to make this connection without have to resort to a custom HLI interface?
I would think we aren't the only ones needing to access Oracle7 from Server2008.
