Inserting/updating XML output to tables

Hi,
I have a nested XML master details record(2 or 3 table). I want to breaking into different columns and insert/update corresponding table.
How I parsed in XML.
Thanks

You need to use extractValue() sql function

Insert / update data to a table through DBLINK (oracle)

I try to insert / update a table from one instance of oracle database to another one through oracle dblink, get following error:

The same code to insert / update the exact same table in local instance works fine.No any binding problem. So i am pretty sure all ? mark in SQL are set with some value before sending to Oracle.
Someone please advise what is possible problem. Db link is not set correctly? or we can not update remote table by dblink.
By the way i can do insert / update from TOAD to the remote table through DBLINK. Problem happens only in Java code.
thanks!
Gary

dblink links from one database instance to another.
So it is certainly a source of possible problems when it works on one database and not another.
You should start by looking at the dblink and it possible testing it in the database not via java.
Note as well that that error suggests that it is coming from the Oracle database. I believe if you had a bind parameter problem in your java code that the error would come from the driver. But that is a guess on my part.

HOw to improve insert/update/select for nested table.

Hi All,
I think this is my second thread for nested table.
i just want to know what are the different ways available to improve the insert/update/select operation on Nested table.
Thanks in advance.

By not using a nested table for data storage in the first place...

Updating XML thru view table

Given the following view table that i created
CREATE OR REPLACE VIEW PO_DETAIL_VIEW ( PAYLOADID,
ORDERNUMBER, LINENUMBER, SHIPPEDITEMQTY, COST,
ORDEREDITEMQTY, ACTION, UOM, DESCRIPTION,
SKU, STATUS, CURRENCY, PLANNEDRECEIPTDATETIME

          extractvalue(value(i),'/OrderLine/@plannedReceiptDateTime')
from PURCHASEORDER p, table(xmlsequence(extract(value(p),'/OrderMessage/Order/OrderLine'))) i
when i executed the following command:
UPDATE po_detail_view
SET ORDERNUMBER = '500001' where PAYLOADID='1'
I get end of file error which disconnect me from my oracle database.
but when i update my another view table it is fine.
CREATE OR REPLACE VIEW PO_MASTER_VIEW ( VERSION,

extractValue(value(p),'/OrderMessage/Order/Buyer/@Role')
from PURCHASEORDER p
UPDATE po_master_view
SET VERSION = '2.0' where PAYLOADID='1'
i can see that the problem lies with
table(xmlsequence(extract(value(p),'/OrderMessage/Order/OrderLine'))) i
is there any better way or solutions to work ard with it?
Thanks.

Thanks Mark,
That's what i suspected the case, will log the itar later when i am free.
Actually my main issue is that I am using forms 9i to view and edit the view tables that are based on the xml schema. Forms is giving me problem in accessing complicating views.
I think my only solution is to:
1)create a custom table updated by the view table.
2)Create my form block based on custom table.
3)update the xml data using updateXML() from the custom table.

Db adapter insert/update/delete output variable

Hi
How can I know how many records have been updated after an insert/update/delete operation done using the db adapter?
I was looking for an output variable to use in the invoke activity of a partnerlink created using the db adapter wizard (update operation), but seems not possible to associate an outpout variable. the update operation is a one way operation. So, what could I do to know how many records was updated?
thanks bye Paolo

The input variable specifies the records to be updated/inserted. If you count these ones, you know how many have been updated. Otherwise the Invoke will fail.

Insert,update and delete data in a table using webdynpro for abap

Dear All,
I have a requirement to create a table allowing the user to add rows in it and update a row as well as delete a row from that table.To do this I guess I have to make use of ALV.But using ALV I am not able to enter data to a table where as I can make a column editable delete a row etc. please guide me to perform these operations(insert,update and delete) on table.
Thanks,
Reddy.

Hi Sridhar,
By using ALV you can do all insert delete etc things. if you want to edit i mean you can yenter data in ALV.

Using Case statement to insert,update,delete the tables

Hi All,
I have to check the databse ,
if it is developement then
insert/update/delete values in tables;
if it staging then
insert/update/delete values in tables;
if it is production then
insert/update/delete values in tables;
thers is function available to check the current database
For doing the about i am trying to write CASE statement like this
SELECT function,
case
when fun = 'developement' then insert into table1 values ('abcd','1234')
when fun = 'staging' then insert into table1 values ('abcd','1234')
when fun= 'production' then insert into table1 values ('abcd','1234')
else null
from dual
its throughing me an error
please help
Thanks,

Hi,
You can use CASE staement any place where an expression is expected.
For example, in:
UPDATE table_a
SET     col1 = exp1
,       col2 = exp2
WHERE   exp3 = exp4;all the expressions are labled lke expn.
Note that table_a, col1 and col2 are not expressions: you must hard-code these names, or use dynamic SQL.
So it's okay to say:
UPDATE table_a
SET     col1 = CASE
                   WHEN db = 'development' THEN 0
                   WHEN db = 'staging'      THEN 1
               END
,       col2 = CASE
                   WHEN db = 'development' THEN NULL
                   WHEN db = 'staging'      THEN col2
               END
WHERE   db != 'production';In this example:
in the development database, col1 is set to 0 and col2 is set to NULL
in the staging database, col1 is set to 1 and col2 is unchanged (that is, set to what it already was)
in the production database, nothing is changed (the WHERE condition is always FALSE)

Interfaces used for insert/update data in tables

for providing security the procedures are not allowed to directly insert/update the values in tables.some one suggested that use interfaces for this .i want infomation about this interfaces. how this works and how to use

An interface is an intermediate set of procedures/functions that do the job for you.
You haven't explained what it is you're trying to achieve exactly, but here's an example scenario.
We don't want to allow our developers to query, or write to the tables directly so they are set up with certain database users that have no permissions granted on the tables for such things.
Instead they have been granted permission to call procedures and functions belonging to another schema, and it is those procedures and functions that do the required table access and/or pass information/data back or write to the tables.
The developers have to write their applications to call these procedures to do any access to the tables. This means that they are limited to the functionality provided by these interface procedures so, if there is internal auditing or columns of data etc. on the tables then it may be that they can't access this data, but only the "user facing" data.
The interface can also ensure that data meets certain requirements before being written to tables, allowing for business or technical level restrictions to be implemented.

How to get last insert/update/delet row of a table?

I hava a table A and table B which is a copy of A. I want to create a trigger to record the changes of A in B. So every time inserting/updating/deleting A I record the row inserted/updated/deleted in B, But I can't find a effiencial way to get the latest row changed.
So is there any sys_var in oracle table like cur_rowid or something to record the latest inserted/updated/deleted in a table? I don't want to check a index or a table to get the max_seq_id again.

Get the list of table's last Inserted/Updated date from a database

Hi All,
Good afternoon!
Please help me to find the last inserted/updated date from different tables in a database.
Consider I have a database called testDB, which contains 20 tables. Most of these tables will get data inserted/updated daily. But sometimes it may not happen due to some issues . We will not be knowing about this issue until we check in each table
manually. Now, somebody should be daily checking for the issues in this db. So, we have decided to make an alert mail to send this informations to us.
We need to check whether any of the table's in TetsDB has got inserted/updated data in one day difference.
I have tried this..
SELECT OBJECT_NAME(OBJECT_ID) AS Object_, last_user_update,*
FROM sys.dm_db_index_usage_stats
WHERE database_id = DB_ID( 'TestDB')
Thanks,
Julie

The solution depends on the version and edition of your SQL Server.
If you use SQL Server 2000 or SQL Server 2005, please visit these links:
How do I audit changes to SQL Server data?
Table Auditing with SQL Server 2000
If your SQL Server 2008 or above (only on the Enterprise edition), please have a look at this link:
Change Data Capture
If your SQL Server 2008 or above (all editions),
you can use Change Tracking, but Change tracking captures the fact that rows in a table were changed, but does not capture the data that was changed.
more info:
Comparing Change Data Capture and Change Tracking
Saeid Hasani [sqldevelop]
HI,
I've read about change tracking change data capturing now.
We need to track the data daily and we need to know whether any modification happens in those tables.
Will it make any performance issue if I enable change data capturing on multiple tables.. lets say 20+ tables.?

Loading xml into relational tables.

I was wondering if anyone knows of a product/libraries which does the following:
-Read data from a relational Database (multiple tables) and generate XML files based upon an XML Schema or DTD file?
-Read XML files and load data into a relational Database.
-Graphical Interface for performing the maps (perhaps based upon .xslt). ie.... Mapping of the XML Schema to Multiple Database Tables, Performing Joins etc...
-Ability to connect to any type of Relational database (not just Oracle). Which rules out XML DB.

This product does look to be ok, however it is missing a couple features that I would like the product to have.
I would like this product to be able to insert/update data across multiple tables. Being able to do such things as generate foreign key relationships.
It doesn't seem as though the XML being generated can be customized very easily. Some XML formats I deal with are very complex (such as X12/EDI).
I would really like a graphical mapper.
Here is a note from the doc:
Storing XML Data Across Tables
Currently the XML SQL Utility (XSU) can only store data in a single table. It maps a canonical representation of an XML document into any table or view. But there is a way to store XML with XSU across tables. You can do this using XSLT to transform any document into multiple documents and insert them separately. Another way is to define views over multiple tables (using object views if needed) and then do the insertions into the view. If the view is inherently non-updatable (because of complex joins), then you can use INSTEAD OF triggers over the views to do the inserts.
This product looks really good, I was hoping that Oracle had something comparable:

Oracle 11g: Oracle insert/update operation is taking more time.

Hello All,
In Oracle 11g (Windows 2008 32 bit environment) we are facing following issue.
1) We are inserting/updating data on some tables (4-5 tables and we are firing query with very high rate).
2) After sometime (say 15 days with same load) we are feeling that the Oracle operation (insert/update) is taking more time.
Query1: How to find actually oracle is taking more time in insert/updates operation.
Query2: How to rectify the problem.
We are having multithread environment.
Thanks
With Regards

Hi Nicolas,
Just a short explanation:
If you have a table with 1 column (let's say a number). The table is empty and you have an index on the column.
When you insert a row, the value of the column will be inserted to the index. To insert 1 value to an index with 10 values in it will be fast. It will take longer to insert 1 value to an index with 1 million values in it.
My second example was if I take the same table and let's say I insert 10 rows and delete the previous 10 from the table. I always have 10 rows in the table so the index should be small. But this is not correct. If I insert values 1-10 and then delete 1-10 and insert 11-20, then delete 11-20 and insert 21-30 and so on, because the index is sorted, where 1-10 were stored I'll now have empty spots. Oracle will not fill them up. So the index will become larger and larger as I insert more rows (even though I delete the old ones).
The solution here is simply revuild the index once in a while.
Hope it is clear.

[www.orbiumsoftware.com]Hmmm, index space not reused ? Index rebuild once a while ? That was what I understood from your previous post, but nothing is less sure.
This is a misconception of how indexes are working.
I would suggest the reading of the following interasting doc, they are a lot of nice examples (including index space reuse) to understand, and in conclusion :
http://richardfoote.files.wordpress.com/2007/12/index-internals-rebuilding-the-truth.pdf
"+Index Rebuild Summary+
+•*The vast majority of indexes do not require rebuilding*+
+•Oracle B-tree indexes can become “unbalanced” and need to be rebuilt is a myth+
+•*Deleted space in an index is “deadwood” and over time requires the index to be rebuilt is a myth*+
+•If an index reaches “x” number of levels, it becomes inefficient and requires the index to be rebuilt is a myth+
+•If an index has a poor clustering factor, the index needs to be rebuilt is a myth+
+•To improve performance, indexes need to be regularly rebuilt is a myth+"
