List the base tables of a view

Hi All,
I have a view but I do not have any information about the base tables and the query that was used to set up this view. Is there a way to atleast list the base tables on which the view was created!
Thanks in advance!
~

SQL> desc user_source
Name Null?
Type
NAME
ARCHAR2(30) - > Name of the View.
TYPE
ARCHAR2(12)
LINE
NUMBER
VARCHAR2(4000) -> will give you the text to
create the View.-----------------------------------------------------------------------------------------------------------------------
For some reason the view I have is not listed in the NAME ..

How to update view without modifying the base table ?

Hi Experts , I need help in two qurstions
1. How to update a view without modifying the base table ?
2. How to write a file unix operating system in pl/sql ? is there any built in procedure is there ?
Thank you

Hi,
I'm not sure what you're asking in either question. It would help if you gave a specific example of what you want to do.

Views don't contain any data; they just query base tables.
You can change the definition of a view (CREATE OR REPLACE VIEW ...) so that it appears that the base table(s) have changed; that won't change the base tables.
2. How to write a file unix operating system in pl/sql ? is there any built in procedure is there ?The package utl_file has routines for working with files.

Updating base table with Materialized View's data

Hi,
In order to update base table with MVs data, I am trying real time data transfer between two databases. One is Oracle 8i and other is Oracle 9i. I have created an updatable MV in 9i on a base table using database link. The base table is in 8i. Materialized View log is created in 8i on base table. MV has to be associated to some replication group, but I am not able to create replication group in 9i to which MV has to be associated. The required packages are not installed.
Replication packages are to be used to create replication group are :
/*Create Materialized View replication group*/
BEGIN
DBMS_REPCAT.CREATE_MVIEW_REPGROUP (
gname => 'TEST_MV_GRP',
master => 'TEST_DATA_LINK',
propagation_mode => 'ASYNCHRONOUS');
END;
But above block is giving error.
Can anyone suggest how to resolve this, or are there any other approaches (by not using replication packages) to update base table with MVs data ?
Thanks,
Shailesh

Yes, I created link between two databases and was able to update tables on 8i from 9i database using that link.
The error I am getting while creating replication group is :
ORA-06550
PLS-00201 : identifier 'SYS.DBMS_REPCAT_UTL2@'TEST_DATA_LINK' must be declared
ORA-06550
PLS-00201 : identifier 'SYS.DBMS_REPCAT_UNTRUSTED@'TEST_DATA_LINK' must be declared
ORA-06512 : at "SYS.DBMS_REPCAT_UTL", line 2394

ORA-06512 : at "SYS.DBMS_REPCAT_SNA", line 64
ORA-06512 : at "SYS.DBMS_REPCAT", line 1262
Is there any other approach which can be used to update base table with MVs data instead of using replication packages ?
Thanks,

Updating a Base Table through a View having UNPIVOT function.

Hi,
I have a requirement of updating a Base Table through a View.
This View has the query using a UNPIVOT function for displaying the columns of the Base tables in rows.
I need to update/insert into/delete the Base Table by accessing the View (The user doesn't have an access to the Base Table, hence the DML's on the View).
Following is the table I've created:-
CREATE TABLE PERSON_DETAILS
PID            VARCHAR2(10 BYTE),
FIRSTNAME      VARCHAR2(1000 BYTE),
LASTNAME       VARCHAR2(1000 BYTE),
PHONENUMBER    VARCHAR2(1000 BYTE),
ADDRESS1       VARCHAR2(1000 BYTE),
ADDRESS2       VARCHAR2(1000 BYTE),
COUNTRY_CODE   VARCHAR2(1000 BYTE),
LANGUAGE_CODE VARCHAR2(1000 BYTE),
EMAIL          VARCHAR2(1000 BYTE)
)The sample values are inserted in this table through the below script:-
insert into person_details values ('1','XYZ','ABC','1234567890','India','Asia','IN','EN','[email protected]');
insert into person_details values ('2','XYZ2','ABC2','1234567890','India','Asia','IN','EN','[email protected]');The code for the view is as below:-
CREATE OR REPLACE FORCE VIEW PERSON_DETAILS_VIEW
   PID,
   CD_NAME,
   CD_VALUE
AS
   SELECT "PID", "CD_NAME", "CD_VALUE"
     FROM person_details UNPIVOT INCLUDE NULLS (cd_value
                         FOR cd_name
                         IN (firstname AS 'First Name',
                             lastname AS 'Last Name',
                             phonenumber AS 'Phonenumber',
                             address1 AS 'address1',
                             address2 AS 'address2',
                             country_code AS 'Country Code',
                             language_code AS 'Language Code',
                             email AS 'Email') );Below are the values from the view:-
PID CD_NAME         CD_VALUE
1    First Name       XYZ
1    Last Name       ABC
1    Phonenumber 1234567890
1    address1         India
1    address2         Asia
1    Country Code   IN
1    Language Code EN
1    Email               [email protected]
2    First Name       XYZ2
2    Last Name       ABC2
2    Phonenumber 1234567890
2    address1         India
2    address2         Asia
2    Country Code   IN
2    Language Code EN
2    Email               [email protected] user would fire some statement like below:-
update person_details_view
set cd_value = 'US' where CD_NAME = 'IN'The above statement should update the base table PERSON_DETAILS.
I understand I can write an INSTEAD OF trigger but I do not know what logic to write in the trigger so that the requirement gets fulfilled.
My Oracle Version
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
PL/SQL Release 11.1.0.7.0 - Production
CORE    11.1.0.7.0    Production

Thank You,

it is definitively possible with an instead of trigger.
for Example:
create or replace
TRIGGER ioft_person
INSTEAD OF UPDATE
ON person_details_view
FOR EACH ROW
declare
firstname1 person_details.firstname%type;
BEGIN
              SELECT firstname_new into firstname1
              FROM   (SELECT pid, cd_name, cd_value

                                                        'Phonenumber' as phonenumber,
                                                        'address1' as address1,
                                                        'address2' AS address2,
                                                        'Country Code' as country_code,

              ) where pid = :old.pid;
UPDATE person_details
SET firstname = firstname1
WHERE pid = :old.pid;
END ioft_role_perm;and than run
update person_details_view
set cd_value = 'X|X' where cd_name = 'First Name' and pid=1The logic is: you must convert back the view through pivoting

In 10g ( 10.1.4.3)OID, what are the base tables

Hi ,I need to clean the users and groups from the OID manually ( i have deleted them using bulkload but oid tree is inconsistent stage)
so now i have to clean them from the base tables,
anyone faced this situation before, appreciate your help.

Check the ORACLE_HOME/ldap/log directory and the contents of oidmon.log and oidldapd01.log
I found a similar error after the 10.1.4.3 upgrade and needed to rerun the root.sh script.
It is helpful to shut everything down, cleanout the log files and file up OPMN (start) and the OID (using startproc).
Good luck!

Need to know the base tables for the QM datasources

Hello SAP Experts,
I want to know the base tables for the below mentioned datasources which stores the transaction data.
1. 2LIS_05_QE1: Inspection Characterstics Results
2. 2LIS_05_QE2: Inspection Characterstics Results (Quan)
3. 2LIS_05_QVUDN: Usage decision for Inspection
Need your inputs.
Thanks,
Lasya.

Hi Lasya,
You can use help.sap.com for this.
If you do not find this data source there...then
You can go to LBWE t-code in R/3 and then infront of the data source...you have maintenance option.
Click on that ...and go inside it in the display mode.
Here you can see a generic pool of fields on the left side which can be included in the data source........ field present in the data sources in the right side of the pool.
For every field you have a tructure name infront of it like MCXXXX where XXXX is the table name.
So the field is being from that particular table.
Even I would the same thing to reply to your thread.
You can follow the same procedure to find the table for any LO data source.
This is accurate in 99% cases...only in very few cases like purchasing...we get one or two fields from different tables.
Hope it helps.
Thanks

Problems when trying to replace the base table of an own Business Object

Dear experts,
some time ago we created two own (not inherited) Business Ojects for use
in workflow scenarios. Now we came into the situation that for organizational
reasons we wanted to exchange the base tables of both the objects.
The fields and keys in the new tables are all the same than in the old ones,
basically just the table names have changed.
The frustrating result of trying to do so are two inconsitent Business objects
that cannot be activated/generated any more with several errors that I cannot
get rid off.
Does anybody have experience with this kind of change in a BO ?
Am I trying that in vain ? Do I have to create them both entirely new?
Please help.
Thanks in advance
Andreas Flügel

Hi Mike,
thanks for the prompt answer.
The first error is a syntax error concerning the unexpected end of a statement
with "LIKE". It occurred in the following generated sourcecode-section after
the generation and it is generated this way again and again (I already tried
to complete it manually according to the way it was before):
BEGIN_DATA OBJECT. " Do not change.. DATA is generated
" end of private,
BEGIN OF KEY,
JOURNALNUMBER LIKE /HOAG/P_DATJOURN-JOURNALNR,
END OF KEY,
_ LIKE.
END_DATA OBJECT. " Do not change.. DATA is generated
The second error points to the table name in the statement
get_table_property /hoag/p_datjourn.
saying "The table name /hoag/p_datjourn is implemented but not defined".
The third error comes up with a popup (again and again and again) saying
"The table is not implemented yet. Do you want a sourcecode sample to be
created for the missing part?". I've alread answered that with "Yes" for a
couple of times without anything being changed.
Thanks
Andreas
P.S.: the messages may actually read a bit different in english because I just
translated them myself from german but I hope you know them well enough to
know what the system wants from me.

I tried to create a materized view but I got this error:
SQL> CREATE MATERIALIZED VIEW TABLE1_MV REFRESH FAST
START WITH
to_date('04-25-2009 03:00:13','MM-dd-yyyy hh24:mi:ss')
NEXT
sysdate + 1
AS
select * from TABLE1@remote_db
SQL> /
CREATE MATERIALIZED VIEW TABLE1_MV REFRESH FAST
ERROR at line 1:
ORA-12014: table 'TABLE1' does not contain a primary key constraint.
TABLE1 in remote_db doesn't have a primary key constraint. Is there anyway that I can create a materized view on a base table which doesn't have a primary key constraint?
Thanks
Liz

Hi,
Thanks for your helpful info. I created a materialized view in the source db with rowid:
SQL> CREATE MATERIALIZED VIEW log on TABLE1 with rowid;
Materialized view log created.
Then I created a MV on the target DB:
CREATE MATERIALIZED VIEW my_schema.TABLE1_MV
REFRESH FAST
with rowid
START WITH
to_date('04-25-2009 03:00:13','MM-dd-yyyy hh24:mi:ss')
NEXT
sysdate + 1
AS
select * from TABLE1@remote_db
SQL> /
CREATE MATERIALIZED VIEW my_schema.TABLE1_MV
ERROR at line 1:
ORA-12018: following error encountered during code generation for
"my_schema"."TABLE1_MV"
ORA-00942: table or view does not exist
TABLE1 exists in remote_db:
SQL> select count(*) from TABLE1@remote_db;
COUNT(*)
9034459
Any clue what is wrong?
Thanks
Liz
