Order child tables.

Hi all,
We've used a GTC to provision to five tables into a database. The connector works fine, but there is a little problem related to manual provision. The four child forms need to be filled in order (tha data into them depends on the previous form), but we can't order them. We've tried to remove them from the parent form and add again in order, but it didn't work. We've also tried to write them in the proper order while creating the GTC without succes.
Is there any way to order them?
Thanks.

Do you mean alphabetical order? If yes, it does not work, OIM doesn't order it in that way

Master Child tables how to get the latest rows from both

Hi,
Need some help with the sql. I have two tables Master & Child. In my Master table I have multiple rows for the same record and in the child table also multiple rows for the same master row how can I get the latest one's from both.
For example Data in my Master table looks like
CONT_ID                  SEQ_NUM        DESCRIPTION
1                         189             Update 2
1                         188             Update 1
1                         187              NewNow in the child table for the same CONT_ID I may have the following rows
CONT_ID                   UPDATED_DATE                                     STATUS
1                        3/16/2010 2:19:01.552700 PM                          P

Here is the query i have but it returns the latest row from the child table only and basically repeats the master table rows as opposed to one row that is latest from both:
Thanks

Hi,
You can use the analytic ROW_NUMKBER function to find the latest row for each cont_id in each table:
WITH     got_m_rnum     AS
     SELECT     cont_id,     seq_num,     description
     ,     ROW_NUMBER () OVER ( PARTITION BY cont_id
                               ORDER BY         seq_num     DESC
                       ) AS m_rnum
     FROM    master_table
--     WHERE     ...     -- any filtering goes here
,     got_c_rnum     AS
     SELECT     cont_id, updated_date,     status
     ,     ROW_NUMBER () OVER ( PARTITION BY cont_id
                               ORDER BY         updated_date     DESC
                       ) AS c_rnum
     FROM    child_table
--     WHERE     ...     -- any filtering goes here
SELECT     m.cont_id,     m.seq_num,     m.description
,     c.updated_date,     c.status
FROM     got_m_rnum     m
JOIN     got_c_rnum     c     ON     m.cont_id     = c.cont_id
                    AND     m.m_rnum     = c.c_rnum
                    AND     m.m_rnum     = 1
;If you'd like to post CREATE TABLE and INSERT statements for the sample data, then I could test this.
If there happens to be a tie for the latest row (say, there are only two rows in the child_table with a certain cont_id, and both have exactly the same updated_date), then this query will arbitrarily choose one of them as the latest.

Selecting Lists/Grids From a Child Table

If I have a parent table "Patient" it has two product tables (Parent Table related 1 <--to--> Many Child Tables) and I make a screen for One Child Table so that it gives me a selection box for the parent table. I can already then
show on the screen properties of the patient from the table I selected. Can I also bring up a List or Grid of the Other Child Table based on the patient I selected?

I don't want to display something in the grid. I want to show all of the entries in that grid for a certain person. I want to grab the grid as a control showing all of the properties in a grid not showing them as individual labels or text etc....
I am not on that entity I am on the orders entity it is already related to the customer to do that to get customer data. The Customer entity/table is related to the allergies entity which is related to Medications to pull up the names of drugs the customer
is allergic too. I want to pull up the whole grid of allergies as a grid I solved this for now by making a single property on the patient table and grabbing all of the rows for a particular patient. then making them one field. I cannot however grab them as
a table and have the advantage of the UI of the grid or list functions.

Accessibility: Reading order of tables and anchored frames

I am creating accessible, tagged (section 508 compliant) PDFs in FrameMaker 9. The reading order for tables and frames is not correct.
When I view the PDF reading order using Adobe Acrobat Professional or another screen reader, anchored items such as tables and anchored frames are placed last in the reading order, regardless of where they appear in the document flow or page layout. The reading order skips over all tables and frames, reading all paragraphs on a page first, then reading the tables and frames as the last objects on the page. This logically doesn't make sense to skip over tables/frames as they generally apply to the content that preceeds it.
For example, the following document structure:
<Paragraph 1>
<Table 1>
<Paragraph 2>
<Anchored Frame 1>
<Paragraph 3>
<Anchor Frame 2>
<Paragraph 4>
is being read by assistive technology as:
<Paragraph 1>
<Paragraph 2>
<Paragraph 3>
<Paragraph 4>
<Table 1>
<Anchored Frame 1>
<Anchor Frame 2>
I want the document structure to be read correctly as intended.
In otherwords, the PDFs generated by FrameMaker 9 are not completely accessible because of incorrect reading order output by default. This information is not listed in the VPAT for FrameMaker 9.
I want to avoid any post processing using Acrobat's Touch Up Reading Order tool. Is there a way to automate updates to reading order?
Can FrameMaker 9 logically place tables and anchored frames into the correct reading order? How do I adjust these settings?
Thanks in advance!

As mentioned above, tables and anchored frames are inserted into thier own paragraph style "Frame". The paragraph style "Frame" is tagged. To my knowledge, there are no options for tagging or not tagging tables or anchored frames.
Regardless of which paragraph type the table or anchor frame is inserted into, and what that paragraphs tagging settings are, it is still last in the reading order.
I've tried a variety of options: tagging the "Frame" paragraph style as a sibling, child, and parent of my other paragraphs; I've even tried omitting it from the reading order. None of these options present anchored frames (and tables) in the logical reading order.
Even images that are inline (within a paragraph; not in thier own paragraph) are not being read as part of the paragraph. Inline images get skipped over by screen readers and get read at the end of the page, which makes no sense whatsoever.
All tables and images end up at the end of the reading order (after ALL paragraphs) regardless of the tagging settings.
Refer to my previous screenshot for a clear diagram of what is happening to the reading order. Each of those anchors is in it's own paragraph style. I want tables and anchored frames to be sequential in the reading order along with paragraphs. (1,2,3,4,5,6 not 1,4,2,5,3,6.)
I'm using the Tags tab of the "PDF Setup" dialog to adjust these settings. Is there somewhere else I should be making changes to the reading order?
This is a bit disturbing because FrameMaker touts creating accessible documents and this severe reading order issue impares my ability to do so. I would not consider documents that jump around the page in an illlogical, fixed order, to be accessible. I'm very suprised that no one else has encountered this issue (at least that I can find...)

Loading to Parent -Child Tables simultaneously

I have a requirement to populate parent-child tables in a single interface simultaneoulsy. I couldnt find anyway to add multiple targets and am wondering why this key feature is absent in ODI. The same thing is easily achievable in BPEL.
Could some one please advice a work around for this.
Your help is much appreaciated

ODI 11g does come with a new IKM 'IKM Oracle Multi Table Insert'. This does allow multi table inserts, but will require more than one interface.
Oracle Multi-Table Inserts
A new Integration KM for Oracle allows populating several target tables from a single source, reading the data only once. It uses the INSERT ALL statement.
COMPONENT NAME: IKM Oracle Multi Table Insert
COMPONENT VERSION: 11.1.2.4
AUTHOR: Oracle
COMPATIBILITY: ODI 11.1.1.3 and above
DESCRIPTION:
     - Integrates data from one source into one to many Oracle target tables in append mode, using a multi-table insert statement (MTI).
REQUIREMENTS:
     - Oracle Database 9iR1 or above
     - See BASIC CONFIGURATION section
BASIC CONFIGURATION
     - This IKM must be used in integration interfaces that are sequenced in a Package:
          - The first interface of the Package must have a temporary target and the KM option DEFINE_QUERY set to YES.
          This first interface defines the structure of the SELECT clause of the multi-table insert statement (that is the source flow).
          - Subsequent integration interfaces must source from this temporary datastore and have the KM option IS_TARGET_TABLE set to YES.
          - The last interface of the Package must have the KM option EXECUTE set to YES in order to run the multi-table insert statement.
          - Do not set "Use Temporary Interface as Derived Table(Sub-Select)" set to true on any of the interfaces.
     - If large amounts of data are appended, consider to set the KM option OPTIMIZER_HINT to /*+ APPEND */.
OPTIONS (Refer to the Option descriptions for more information on each option)
     - DEFINE_QUERY: Set to Yes if this interface describes the source query (SELECT clause of the statement). This interface must have a temporary target.
     - IS_TARGET_TABLE: Set to Yes this interface using the source query to load one of the target tables. This interface must source from an interface with a temporary target using this IKM and having the KM option DEFINE_QUERY set to YES.
     - EXECUTE: Set to Yes for the last interface in the Package. This interface will run the multi-table insert statement.
     - COMMIT: Commit transaction. This applies only to the last interface in the Package.
     - TRUNCATE: Set to Yes to truncate this interface target table.
     - CREATE_TARG_TABLE: Create target table? May only be used on target interfaces, but not on source interfaces (defining the source data).
     - OPTIMIZER_HINT: Hint for the multi-table insert statement.
RESTRICTIONS:
     - This KM can only be used in integration interfaces that are part of a Package.
     - All source and target datastores need to reside on same data server.
     - Journalized source data is not supported.
     - Temporary indexes are not supported.
     - Flow/static control is not supported.
     - The TRUNCATE option cannot work, if the target table is referenced by another table (foreign key).

How to create index on XMLTYPE ordered collection table?

I am using Oracle 11.2.0.2.
Essentially, my XML documents have a 3-level hierarchy:
event
+---action [1:n]
         +---- param   [1:n]
I am trying to create indexes on ordered collection tables, but can not get the syntax right...
I have created a table with an object-relational XMLType column:
CREATE TABLE T_C_RMP_MNTRNG_XML_FULL_IL4 (

How can I create an index on these ordered collection tables in order to improve performance?
I found the example at http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_rewrite.htm#ADXDB5859 but am not able to apply it to this particular case...
Thank you in advance...

If the schema is not annotated then xs:integer and xs:string are mapped to NUMBER and VARCHAR2(4000) datatypes, so you have to use those in your query in order to avoid unnecessary typecasting operations.
You should also use chained XMLTABLEs when accessing a parent/child relationship instead of a FLWOR expression, otherwise the CBO may not rewrite the XQuery correctly (maybe it's fixed in the latest release).
If you make those changes, the plan should show cleaner predicates :
SQL> SELECT EVENT_ID, ACTION_SUB_ID, MESSAGE_ID, ACTION_TYPE, ACTION_TIMESTAMP
2 FROM test_table,
3 XMLTABLE('/monitoring'
4    PASSING XML_CONTENT COLUMNS
5      EVENT_ID         VARCHAR2(4000) PATH 'eventId',
6      actions          XMLTYPE        PATH 'action'
7    ) T1,
8 XMLTABLE('/action'
9    PASSING actions COLUMNS
10      ACTION_SUB_ID    NUMBER PATH 'actionSubId',
11      ACTION_TYPE      VARCHAR2(4000) PATH 'type',
12      ACTION_TIMESTAMP NUMBER PATH 'time'
13 ) T2
14 WHERE EVENT_ID IS NOT NULL
15 AND ACTION_SUB_ID IS NOT NULL

XML Query filtering by child table column

Hello,
If anyone can help with this one... it would be nice. I need to make the output of an query to be in the format of XML, but the problem is that the initial filtering needs to be done in the child table.
Example:
CREATE TABLE PRIMARY(
ID NUMBER(19,0),
CODE_PRIMARY VARCHAR2(32));
CREATE TABLE SECONDARY(
ID NUMBER(19,0),
IDPRIMARY(19,0),
CODE_SECONDARY VARCHAR2(32));
INSERT INTO PRIMARY(ID,CODE_PRIMARY)
VALUES (1,'A');
INSERT INTO PRIMARY(ID,CODE_PRIMARY)
VALUES (2,'B');
INSERT INTO SECONDARY(ID,IDPRIMARY,CODE_SECONDARY)
VALUES (1,1,'C');
INSERT INTO SECONDARY(ID,IDPRIMARY,CODE_SECONDARY)
VALUES (2,1,'D');
INSERT INTO SECONDARY(ID,IDPRIMARY,CODE_SECONDARY)
VALUES (3,2,'E');
Now what we need is to build an XML tree like the following, INNER JOINING PRIMARY and SECONDARY tables with this condition in the where clause -> WHERE SECONDARY.CODE IN ('C','D')
<result>
<record>
<id>1</id>
<code>A</code>
<childs>
<child>
<id>1</id>
<idprimary>1</idprimary>
<codesecondary>C</codesecondary>
</child>
<child>
<id>2</id>
<idprimary>1</idprimary>
<codesecondary>D</codesecondary>
</child>
</childs>
</record>
</result>
In this example only one record is returned since we only have one record in PRIMARY table that has a child having codesecondary=C or D. The ideia is to get many records... but I think that this is enough for the sake of the example. And the solution is the same.
Thanks in advance!

Found the answer. Used distinct keyword instead of grouping the output table columns. This way XMLAgg didn't broke up the result:
SELECT
XMLElement("Processos",
XmlAgg(XMLElement("Processo",
XMLForest(T.ID as "Id",T.CODIGO as "Codigo",T.DESCRICAO as "Descricao"),
XMLElement("Funcionalidades",
SELECT
XMLAgg(
XMLElement("Funcionalidade",F2.ID)
FROM TWBASEDB.LISTA_UNICA_FUNCIONALIDADE F2
WHERE F2.ID_processo=T.ID
and f2.ACTIVIDADE IN ('1_ACTC1','1_ACTC2','1_ACTC3','2_ACTC1')
from
select distinct P.ID,P.CODIGO,p.DESCRICAO
FROM TWBASEDB.LISTA_UNICA_PROCESSOS P
INNER JOIN TWBASEDB.LISTA_UNICA_FUNCIONALIDADE F ON P.ID=F.ID_PROCESSO
WHERE ACTIVIDADE IN ('1_ACTC1','1_ACTC2','1_ACTC3','2_ACTC1')
order by p.id

How to find out master tables and concern child tables

Hi,
my schema contains 219 tables. I got this result by using query "selct count(*) from user_tables".
Now i need to know about master tables and concern child tables from these 219 tables.
please guide me.
Thanks and Regards,

Why is the child table inserting first in a composite association?

Guys and Gals,
Studio Edition Version 11.1.1.3.0.
This one has gotten me all day. I have a child table which is inserting before its master table, even though the relationship is defined as a composite relationship.
Process:
1) User adds a part with a purchase price into the Part table.
2) Via Part-PartHistories View Link, part is inserted into PartHistories.
3) Via BPL-BPLRows View Link, part is inserted into BPLRows along with its purchase price. The part number is part of a composite primary key (BPL,PartNumber) and is a foreign key to the Part table.
4) Via BPL-PL View Link, and then Via PL-PLRows View Link, part is inserted into PLRows along with its purchase price. The part number is part of a composite primary key (PL,PartNumber) and is a foreign key to the Part table.
It is #4 which gives me an integrity constraint (PCS.PRICE_BUCKETS_PARTS_FK1) violated - parent key not found error. JDev is trying to insert in the order 4,1,2,3 when it should be 1,2,3,4. The kicker is that there is a composite association between #1 and #4 which should guarantee that 1 is inserted first. If I remove #4's process, steps 1-3 run fine. If I remove the composite association, JDev inserts correctly steps 1,2,3,4.
Why is JDev trying to insert #4 first? I do a CreateInsert on the Parts table first so the creation order is correct. Furthermore, there is a composite association defined between Parts - PLRows.
Something is indeed fishy in Denmark.

LovettWB,
You talk about VOs, but composite relationships need to be defined at the EO level. If you have indeed defined the proper composite associations, this sounds like a perfect test case to submit to Oracle Support to evaluate.
If you do have the proper associations set up and things don't work, you could try [url http://download.oracle.com/docs/cd/E17904_01/web.1111/b31974/bcadveo.htm#CEGECADE]this technique as a workaround.

11g child table update locking

Hi,
I'm posting this question after searching on multiple places and trying to understand 11g locking mechanism.
I've a table TXN1 transaction and has FKs to 3 different tables Account, customer, country and currency. ALL FKs are indexed (bitmap). I am updating TXN1 of amount column about 10,000 rows. (SID 1) As expected, it has taken lock type 3 SX on TXN1. But it has taken on lock type 4 (share) on Account, customer and country. Committing every 10k rows.
At the same time sid 2 is inserting into another TXN2 table which has FK to the same dimensions account, customer and currency. Only FK on ac_id is bitmap indexed. The inserts have taken SX lock(type 3) on tXN2 table (expected). But it is trying to take SX type 3 lock on account, customer, currency tables. typ3 lock taken on CCY but waiting on CST. But It is blocked by sid 1. It has resulted into Enque-TM contention and resulted into anywhere 60-300 secs wait time..
I understand update/delete in parent table results into locking of SX of child tables and need the FKs to be indexed to avoid etc. I didn't understand the following and appreciate if someone can help me.
1. Why is SID1 taking shared lock on the parent tables Account,customer,country and currency tables? The update statement is not updating any of those FK columns nor referring them in where clause(if it matters!). Is it to ensure that the parent rows are not deleted?
2. Why is SID2 taking SX lock on the dimension tables? Why is it not taking RS lock type 2 on parent rows? Why is SID1 taking shared lock type 4, but not 2?
Thanks
Ram

How to find out child tables given a parent table /parent's constraint_nam

Hi
I need to disable a primary key but is not able to becoz of referential constraint
select child_constraint.table_name, child_constraint.constraint_name, child_detail.column_name
from user_cons_columns child_detail
join user_constraints child_constraint
on child_detail.constraint_name = child_detail.constraint_name
and child_detail.owner = child_detail.owner
and child_detail.table_name= child_detail.table_name
where child_constraint.constraint_type='R'
and child_constraint.status='ENABLED'
and child_constraint.r_constraint_name='SUBSCRIBER_PK';
and child_detail.table_name='ADDRESS_BOOK_GROUP';
Given a table name how would I know all the child tables and the child tables' columns referencing the parent keys?
thanks

thanks for the reply
while the first query is correct
select child_constraints.table_name child_table_name, child_detail.constraint_name child_constraint_name
, child_detail.column_name child_column_name, child_constraints.constraint_type child_constraint_type
, child_constraints.status, parent_constraints.table_name parent_table_name, parent_detail.column_name parent_column_name

and child_constraints.constraint_type='R'
and parent_constraints.constraint_type='P'
--and child_constraints.status='ENABLED'
order by child_constraints.table_name
, child_detail.position
the second query return a lots of garbage why is this so?
select child_constraints.table_name child_table_name, child_detail.constraint_name child_constraint_name
, child_detail.column_name child_column_name, child_constraints.constraint_type child_constraint_type

Creation order fo tables

I Generate Database from Server Model but the DDL statements which create the tables, are generated in a bad order. For example, first create a child table and later the father table.
How can I specify the cration order for the tables?

I don't think it makes any difference as all the generated objects go into separate files. Therefore your constraints are added after every table has been created.

Retrieving all FK from child table in a resultset

I have a parent and its child table.In child table there are many records containing the same PK of the parent as a foreign key(one to many relationship).Now how can I get all those values (in a resultset) of child table containing the same FK .The code i produced can fetch the first record of the same PK of the parent.But how can I get all with a single SQl statement and iterate through them as necessary.
String sql1="SELECT * FROM ChildTableName WHERE id= ' 100 ' ; //100 is the PK of Parent table // there are many records in Child Table having 100 as foreign key resultset = statement.executeQuery(sql1); resultset .next();      try{          System.out.println("Data> "+resultset.getString(1));         System.out.println("Data> "+resultset.getString(2));         System.out.println("Data> "+resultset.getString(3));   }catch(SQLException sqle){System.out.println("ERROR REFRESH : " + sqle); }{code} Edited by: Tanvir007 on Apr 17, 2008 4:35 AM Edited by: Tanvir007 on Apr 17, 2008 4:37 AM Edited by: Tanvir007 on Apr 17, 2008 4:40 AM

However brother many thanks for an attempt to help me.I think I have solved the problem-
try{

                    }catch(SQLException sqle){ sqle.printStackTrace();           }But the problem is, The fields in my DB are in this serial- rent_id,flat_name,flat_rent,elec_reading,elec_bill,total_rent,status
But as you can see from the code that I get the Flat name in 1,Rent in 2 and bill in 3 which should be 2,3,5 respectively.Can you tell me why it is so?
