XSU insert into join view

I've looked through a lot of the discussions here, and seen the
same question I have:
How do you use XSU to insert XML into master-detail structure?
And the answer seems to be, "insert into a view".
Could you give me example SQL for the type of view you mean?
And how the XML might look?
(is it like...
<ROWSET>
<ROW>
<MASTER_KEY>KEYVALUE</MASTER_KEY>
<MASTER_ATTR>SOME MASTER ATTRIBUTE</MASTER_ATTR>
<MASTER_ATTR2>ANOTHER ATTRIBUTE</MASTER_ATTR2>
</ROW>
<ROW>
<DETAIL_FK>KEYVALUE</DETAIL_FK>
<DETAIL_ATTR>DETAIL ROW ATTRIBUTE</DETAIL_ATTR>
</ROW>
<ROW>
<DETAIL_FK>KEYVALUE</DETAIL_FK>
<DETAIL_ATTR>ANOTHER DETAIL ROW</DETAIL_ATTR>
</ROW>
</ROWSET>
null

I do not have TOAD, but I tried your posted example from PL/SQL Developer and it seems to work as expected. Can you post some more detail as to how you are doing it from TOAD and what the issue is, with errors, if any:

Inserting into XMLType View

I have created an XMLType view with an INSTEAD OF trigger to insert data into the underlying tables. I used your example on XMLType view of Relational Content
It works great if I have no attributes defined in the root element of the XML document (i.e. xmlns, schemaLocation, etc.). However, if my document contains any of those attributes, it will not load. I have tried creating the view with and without the xml attributes, as well as making sure that the schemaLocation is identical to the one in the document (copied and pasted just to make sure).
Is there anything that you can point to right away that I'm missing?
If needed, I can post code for you.
Thanks!

Here is the code I used to generate the tables, view, and triggers:

Problem Inserting into object view with OracleXmlSave

Gurus,
I'm trying to insert into an object view with
multiple collections of objects representing a master/detail relationship and a CLOB column, but I've this error:
oracle.xml.sql.OracleXMLSQLException: Error Interno
at oracle.xml.sql.dml.OracleXMLSave.saveXML(OracleXMLSave.java:1967)
at oracle.xml.sql.dml.OracleXMLSave.insertXML(OracleXMLSave.java:1060)
at onix.interface_isbn.OnixXmlLoader.doInsert(OnixXmlLoader.java:165)

at onix.interface_isbn.OnixXmlLoader.<init>(OnixXmlLoader.java:23)
at onix.interface_isbn.correrLoader.main(correrLoader.java:77)
I'm using OracleXmlSave with insertXML method to do this.
Is There any limitations to do that? (example
number of tables into the view, columns datatype).
I'd appreciate any comments
Thank

No known limitations. Please post the sample DDL to create your object types and object view, along with an example of the example XML document you're trying to insert.

How can I insert into a view cache???

I have a problem in JClient like that:
A form that have 3 JTable:
- Table1 get data from UserTable in DB
- Table2 get data from GroupTable in DB
- Table3 get data from GroupTable in DB
and 2 buttons: btnAdd, btnRemove.
When I select a row in Table1, Table2 will get all records in GroupTable that row in Table1 belonging to and Table3 will get all records in GroupTable that row in Table1 not belonging to.
I want that when I select some rows in Table3 and click btnAdd then those rows in Table3 will be insert into Table2 and remove those rows from Table3. And when I select some rows in Table2 and click btnRemove then those rows in Table2 will be insert into Table3 and remove those rows from Table2.
Can you show me how to show that problem.
Thanks.

Hi,
When do you get this error? Is it while running or while creating the form.
Here is a sample code which inserts a non-database column dummy into a table called dummy. This is done in successful procedure.
declare
l_dummy varchar2(1000);
begin
l_dummy := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT',
p_attribute_name=>'A_DUMMY');
insert into sjayaram903_1g.dummy values(l_dummy);commit;
end;
Please check in your case if the size of the local variable is enough to hold the values being returned.
Thanks,
Sharmila

BULK INSERT into View w/ Instead Of Trigger - DML ERROR LOGGING Issue

Oracle 10.2.0.4
I cannot figure out why I cannot get bulk insert errors to aggregate and allow the insert to continue when bulk inserting into a view with an Instead of Trigger. Whether I use LOG ERRORS clause or I use SQL%BULK_EXCEPTIONS, the insert works until it hits the first exception and then exits.
Here's what I'm doing:
1. I'm bulk inserting into a view with an Instead of Trigger on it that performs the actual updating on the underlying table. This table is a child table with a foreign key constraint to a reference table containing the primary key. In the Instead of Trigger, it attempts to insert a record into the child table and I get the following exception: +5:37:55 ORA-02291: integrity constraint (FK_TEST_TABLE) violated - parent key not found+, which is expected, but the error should be logged in the table and the rest of the inserts should complete. Instead the bulk insert exits.
2. If I change this to bulk insert into the underlying table directly, it works, all errors get put into the error logging table and the insert completes all non-exception records.
Here's the "test" procedure I created to test my scenario:
View: V_TEST_TABLE
Underlying Table: TEST_TABLE
PROCEDURE BulkTest
IS
TYPE remDataType IS TABLE of v_TEST_TABLE%ROWTYPE INDEX BY BINARY_INTEGER;
varRemData remDataType;
begin
select /*+ DRIVING_SITE(r)*/ *
BULK COLLECT INTO varRemData
from TEST_TABLE@REMOTE_LINK
where effectiveday < to_date('06/16/2012 04','mm/dd/yyyy hh24')
and terminationday > to_date('06/14/2012 04','mm/dd/yyyy hh24');
BEGIN
FORALL idx IN varRemData.FIRST .. varRemData.LAST
INSERT INTO v_TEST_TABLE VALUES varRemData(idx) LOG ERRORS INTO dbcompare.ERR$_TEST_TABLE ('INSERT') REJECT LIMIT UNLIMITED;
EXCEPTION WHEN others THEN
DBMS_OUTPUT.put_line('ErrorCode: '||SQLCODE);
END;
COMMIT;
end;
I've reviewed Oracle's documentation on both DML logging tools and neither has any restrictions (at least that I can see) that would prevent this from working correctly.
Any help would be appreciated....
Thanks,
Steve

Thanks, obviously this is my first post, I'm desperate to figure out why this won't work....
This code I sent is only a test proc to try and troubleshoot the issue, the others with the debug statement is only to capture the insert failing and not aggregating the errors, that won't be in the real proc.....
Thanks,
Steve

How to putXML on a joined View?

Hi
I would like to insert an XML document into two tables (some
elements into table 1 and some into table 2). I have created a
joined view of the two tables and have tried to insert into the
view with:
java OracleXML putXML -user %USER_PASSWORD% -filename myfile.xml
myView
But I get the error "cannot modify a column which maps to a non
key-preserved table". PLEASE GIVE A SPECIFIC EXAMPLE OF AN
UPDATABLE 'VIEW' WHERE AN INSERT CAN MODIFY MORE THAN ONE
UNDERLYING TABLE. Is it possible?
Any example will do. But here is what I tried to do. I tried
to map the first few ROW child elements of an XML document (shown
at the bottom) into columns of the EMP table and the remaining
child
elements into another table called RELATIVE (this is a table
containing next-of-kin contact information for each employee). I
created a RELATIVE table with:
CREATE TABLE RELATIVE (
IDREL NUMBER(15) PRIMARY KEY,
EMPNUM NUMBER(4) CONSTRAINT FK_REL REFERENCES SCOTT.EMP(EMPNO),
RNAME VARCHAR2(20) NOT NULL,
TEL NUMBER(14),
STREET VARCHAR2(30),
CITY VARCHAR2(20),
STATE VARCHAR2(10),
ZIP VARCHAR2(12),
COUNTRY VARCHAR2(20)
I added a EMPNO_DUP column to the EMP table that is a copy of
the
EMPNO primary key (I did this so as to use EMPNO_DUP for the two
table join, rather than the EMPNO primary key. My first attempts
to make the joined view with EMPNO also gave the same error). I
wrote a PL/SQL trigger than would make sure that EMPNO_DUP and
EMPNO remain in synch if EMPNO is updated or if there is an
INSERT on EMP. Then I created a joined view of EMP and RELATIVE
with:
CREATE OR REPLACE VIEW EMPREL
(EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO, EMPNO_DUP
IDREL, EMPNUM, RNAME, TEL, STREET, CITY, STATE, ZIP, COUNTRY)
AS SELECT
E.EMPNO, E.ENAME, E.JOB, E.MGR, E.HIREDATE, E.SAL, E.COMM,
E.DEPTNO,E.EMPNO_DUP,
R.IDREL, R.EMPNUM, R.RNAME, R.TEL, R.STREET, R.CITY, R.STATE,
R.ZIP, R.COUNTRY
FROM EMP E, RELATIVE R WHERE E.EMPNO_dup=R.EMPNUM;
I tried to insert the XML document shown at the bottom with:
java OracleXML putXML -user %USER_PASSWORD% -filename myfile.xml
myView
I also tried the direct SQL command:
INSERT INTO EMPREL
(EMPNO, ENAME, JOB, MGR, HIREDATE, SAL, COMM, DEPTNO,EMPNO_DUP,
IDREL, EMPNUM, RNAME, TEL, STREET, CITY, STATE, ZIP, COUNTRY)
VALUES
(7944, 'WIZARD', 'CLERK', 7782, '25-JUL-82', 1325, 0, 10, 7944,
1, 7944, 'SUE', 4087200111, '200 MAIN ST.', 'PALO ALTO', 'CA',
'94043', 'USA')
Both attempts resulted in this error message:
"cannot modify a column which maps to a non key-preserved table"
I would really appreciate an example of how to create an
updatable view where two or more underlying tables can be
modified. Thanks.
Regards
Mehran Moshfeghi
Here is the sample XML file. I want the first set of elements to
map to EMP table columns and the second set of elements (after
the blank line) to map to the RELATIVE table columns.

Hi Mehran,
This is a classic view update problem where the database cannot
figure out automatically which table(s) to update given a join
view. Any update/insert/delete cannot act on more than one
table.So if you are updating a column in a join-view, then that
column must map to a particular column of a single table
unambigously. You should look at the documentation on updatable
join views.
One of the easiest solutions to your problem is to create
INSTEAD-OF trigger on those views. INSTEAD-OF triggers are
triggers that can be created over non-updatable views to make
them updatable. Here in the trigger body you specify the
appropriate insert statements into the base tables. So your view
can be as complicated as possible and yet updatable using these
triggers.

About insert into MDSYS.SDO_GEOM_METADATA_TABLE

Hi all,
I'm newbie with Oracle Spatial.
I would like to know what values can I define to columns SDO_LB and SDO_UB
for the dim element for SRID 8292 when I insert into table
MDSYS.SDO_GEOM_METADATA_TABLE.
I found the following example:
INSERT INTO MDSYS.SDO_GEOM_METADATA_TABLE
       SDO_OWNER, SDO_TABLE_NAME, SDO_COLUMN_NAME,
       SDO_DIMINFO,
       SDO_SRID)
VALUES('PROJUSER', 'LOCAL', 'CD_LOCAL',
MDSYS.SDO_DIM_ARRAY(MDSYS.SDO_DIM_ELEMENT('X', 500000, 600000, 0.05),
                    MDSYS.SDO_DIM_ELEMENT('Y', 7000000, 7020000, 0.05)),
8292);But I don't know if this insert is correct and the spatial index
is valid for SRID 8292.
Thank you very much!!!
[]´s

Hi,
8292 is a Geographic system, so this is the correct entry for metadata:
insert into user_sdo_geom_metadata values ( ...,
SDO_DIM_ARRAY(SDO_DIM_ELEMENT('X', -180, 180, .05),
SDO_DIM_ELEMENT('Y', -90, 90, .05)), 8292);
And you should never insert directly into the MDSYS.SDO_GEOM_METADATA_TABLE table.
You should always insert into USER_SDO_GEOM_METADATA view.

Insert order by records into a view with a instead of trigger

Hi all,
I have this DML query:
INSERT INTO table_view t (a,
                          b,
                          c,
                          d,
                          e)
      SELECT   a,
               b,
               c,
               d,
               e
        FROM   table_name
    ORDER BY   dtable_view is a view with an INSTEAD OF trigger and table_name is a table with my records to be inserted.
I need the ORDER BY clause because in my trigger i call a procedure who treat each record and insert into a table, used in the view. I need to garantee these order.
If i put an other SELECT statement outside, like this:
INSERT INTO table_view t (a,
                          b,
                          c,
                          d,
                          e)
      SELECT   a,
               b,
               c,
               d,
               e
        FROM   table_name
    ORDER BY   dIt works. But I can put these new SELECT because these query is created automatic by Oracle Data Integrator.
What I'm asking you is if there any solution to this problem without changing anything in the Oracle Data Integrator. Or, in other words, if there is any simple solution other than to add a new SELECT statement.
Thanks in advance,
Regards.

Sorry... copy+paste error :)
INSERT INTO table_view t (a,
                          b,

                  FROM   table_name
              ORDER BY   d)I need to insert him by a D column order, because my trigger needs to validate each record and insert him. I have some restrictions. For example, my records are:
2     1     2006     M
1     2     2007 M
1     3     2007     S 2007
1     2     2007     S 2007
2     1     2009     S
2     1     2009     S
I want to insert the 'M' records first and then the 'S' records because the 'S' records only makes sense in target table is exists 'M' records

Insert into multiple table view

I have a view with multiple table query and and INSTEAD OF trigger on the view that inserts into multiple tables. When I attempt to do a commit out of a ADF Creation Form, I get the following error: ORA-01779: cannot modify a column which maps to a non key-preserved table ORA-06512: at line 1.
Has anyone had success inserting into multiple tables via a view that has more than one table?
Thanks,
Lisa

Lisa,
Sounds like your instead-of trigger may not be being called and you are trying to insert directly into the view.
I did write a [url http://stegemanoracle.wordpress.com/2006/03/15/using-updatable-views-with-adf/]blog entry about using a view with instead-of triggers last year.

Need code for dynamic insertion of a MIME object(image) into WebDynpro View

Hi experts,
I am attempting to insert an image into a view at runtime, using lines of code.
I know that this code must be present in the WDDOMODIFYVIEW method of that particular view.
However I am not sure about the lines of code which can do this. Can anyone please help me out with this........
Thanks in advance,
Adithya.

Hi.,
Yes you can add MIME at runtime ., Check this.,
[MIME at run in WDA |Can mime object be created at run-time?;
also ., [Display logo at runtime in WDA|Mime logo not displaying;
hope this helps u.,

Inserting into a doubly nested table through an object view

Can anyone give me an example of an INSTEAD OF trigger that will mediate an INSERT into a doubly nested table of an Object View? Is there syntax that will allow it?

Problem inserting XML into object view

Hi all,
My environment is :
Windows NT 4.0
Oracle 8i 8.1.5
(NLS_CHARACTERSET = EL8MSWIN1253)
Apache 1.3.11 Web Server
Apache JServ 1.1
XSQL v 0.9.9.1 and XML parser for Java v2,
XMLSQL that come with it
I've created an object view as following :
create table schedules (
schedule_id varchar2(20),
description varchar2(100),
constraint pk_schedule_id primary key (schedule_id)
create table schedule_details (
schedule_id varchar2(20),
starting_time date,
duration number,
constraint pk_schedule_dtls primary key (schedule_id, starting_time),
constraint fk_schedule_id foreign key (schedule_id) references schedules (schedule_id)
create or replace type schedule_detail_t as object (
starting_time varchar2(20),
duration number
create or replace type schedule_detail_list as table of schedule_detail_t;
create or replace type schedule_details_t as object (
schedule_id varchar2(20),
description varchar2(100),
details schedule_detail_list
create or replace view schedule_details_view of schedule_details_t
with object OID (schedule_id)
as select schedule_id, description,
cast(multiset(select schedule_detail_t (to_char(starting_time, 'hh24:mi'), duration) as Detail
from schedule_details
where schedule_details.schedule_id = schedules.schedule_id
) as schedule_detail_list )
from schedules;
And I'm trying to insert using putXML this
<?xml version = "1.0" encoding = "ISO-8859-1"?>
<ROWSET>
<ROW>
<SCHEDULE_ID>S1112</SCHEDULE_ID>
<DESCRIPTION>Working 08:00 to 20:00</DESCRIPTION>
<DETAILS>
<DETAILS_ITEM>
<STARTING_TIME>08:00</STARTING_TIME>
<DURATION>12</DURATION>
</DETAILS_ITEM>
</DETAILS>
</ROW>
</ROWSET>
The error I get is
oracle.xml.sql.OracleSQLXMLException:
non supported oracle-character-set-174
Note: no rows have been inserted
at oracle.xml.sql.dml.OracleXMLSave.insertXML
When I'm posting using XSQL the XML doesn't get inserted with no error message.
But when I try this for a change
<?xml version = "1.0" encoding = "ISO-8859-1"?>
<ROWSET>
<ROW>
<SCHEDULE_ID>S1111</SCHEDULE_ID>
<DESCRIPTION>Working 08:00 to 20:00</DESCRIPTION>
</ROW>
</ROWSET>
Trying to insert into table (this time) "schedules" using putXML it works ...
It works on tables and it doesn't work on object views.
Any piece of advice will be highly appreciated.
Nick

No known limitations. Please post the sample DDL to create your object types and object view, along with an example of the example XML document you're trying to insert.

Inserting into views

Hi everybody.
I have a question regarding inserting data through views.
One can insert and delete rows through a view only if the view definition doesn't have the following:1. Distint clause
2. Group By clause
3. Start With clause
4. Connect By clause
5. ROWNUM clause
6. Subquery in the select clause
7. Set operators
Can you please tell me why is this restriction placed?

For the same reason we can't do DML with views that are joins of more than one table: a row in the view does not, cannot map to a single row in the underlying table (or, in the case of ROWNUM, to a column in that table).
If you have a need to do this sort of thing you need to investigate INSTEAD OF triggers. But approach with caution.
Cheers, APC
