MS SQL to Oracle Integration.

Hi,
I want to load data from MS SQL to Oracle using interface. Can anybody tell me what are the steps to do this using ODI tool ?
Which LKM,IKM I should use for this ?
Thanks in advance,

It depends on what you want to do and the size of the data you are moving from SQL (MySQL or MSSQL) to Oracle. But take a look at the variables "Array Fetch Size" and "Batch Update Size" in topology manager for both target and source data servers. These values makes ETL faster or slower.
If you want to do a truncate&load, you need to use SQL to Oracle Knowledge Modules which comes out of the box.
If you want a Incremental Update or Slowly Changing Dimensions mechanism you can load data to Oracle (with method upside) then write a second interface for the mechanism.
I had the same issue but I've written my own Knowledge Modules (without using any staging tables) that I call "SQL to Oracle directload" which loads data on-the-fly mode and it supports SCD and Incremental Update as well.
Cheers.

About SQL and Oracle

Hello, I was using a MySQL database and i will soon use Oracle8. I was wandering if Oracle authorize something like mysql_result... I'm looking too for simple documentation about connecting to an Oracle database from a php file using Sql. Do u know books or sites ? Tks

Does Oracle support T-SQL ? Why would Oracle support a proprietary macro-based language implementation from a competitor?
If it is not supported in Oracle, what is the major grammer difference between T-SQL and Oracle supported SQL ? Oracle has two languages. SQL. PL/SQL.
PL/SQL is formal declarative procedural language with object orientation programming features. It is based on the Ada language (close relative of the Pascal language).
SQL is fully integrated with PL/SQL. Which means that you can write and mix SQL source code with PL/SQL source code and the PL/SQL compiler will figure out which is which and where to make calls to the SQL engine for executing SQL code.
Is there any efficient way for programmer to complete T-SQL transition to Oracle SQL ? Yes. Unfortunately not the answer that you are likely hoping for.
Forget EVERYTHING you did with T-SQL.
There is no real comparison between the two. And not only many differences, but some fundamental and conceptual differences too.

Can we use Dynamic SQL in Oracle Reports ?

Hi ,
Can we use Dynamic SQL in Oracle Reports ?
If yes please give some examples .
Thanx

I believe the built-in package SRW.Do_Sql is what you are looking for
Example from the document:
/* Suppose you want to create a "table of contents" by getting the
** first character of a columns value, and page number on which its
** field fires to print. Assume that you want to put the "table of
contents"
** into a table named SHIP. You could write the following construct:
DECLARE
PAGE_NO NUMBER;
PAGE_FOR INDEX NUMBER;
SORT_CHAR CHAR(1);
CMD_LINE CHAR(200);
BEGIN
SORT_CHAR := :SORT_NAME ;
IF :CALLED = Y THEN
     SRW.GET_PAGE_NUM(PAGE_FOR_INDEX);
     SRW.USER_EXIT(RWECOP PAGE_FOR_INDEX
     P_START_PAGENO);
     SRW.MESSAGE(2,TO_CHAR(:P_START_PAGENO));
END IF;
SRW.GET_PAGE_NUM(PAGE_NO);
CMD_LINE := INSERT INTO SHIP VALUES
                      (||SORT_CHAR||,||TO_CHAR(PAGE_NO)||);
SRW.MESSAGE(2,CMD_LINE);
SRW.DO_SQL(CMD_LINE);
COMMIT;
EXCEPTION
WHEN DUP_VAL_ON_INDEX THEN
        NULL;
WHEN SRW.DO_SQL_FAILURE THEN
        SRW.MESSAGE(1,FAILED TO INSERT ROW INTO SHIP TABLE);
WHEN OTHERS THEN
       COMMIT;

SQL Server Oracle If else differences

I have a query in SQL Server 2008 that uses an if statement to determine how the SQL is returned. It is fairly complex but here it is in its basic form.
declare @granularity varchar(20);
begin
set @granularity = 'Month';
if (@granularity = 'Month')
begin
select count(*) as DisplayCount, yearstep, monthstep
from MyTable
group by yearstep, monthstep
order by yearstep, monthstep
end
else
if (@granularity = 'Year')
begin
select count(*) as DisplayCount, yearstep
from MyTable
group by yearstep
order by yearstep
end
end
Originally I thought the conversion would be as easy as changing the @ to :, adding a then and an end if. Not so....
Can anyone show what the Oracle equivalent would be?
Edited by: user497094 on Aug 20, 2010 12:51 PM

If you use SQL Developer tool, you have a translator to translate T-SQL to Oracle PL/SQL language.
For your example, you should get:
BEGIN
v_granularity := 'Month' ;
IF ( v_granularity = 'Month' ) THEN
BEGIN
SELECT COUNT(*) DisplayCount,
yearstep,
monthstep
FROM MyTable
GROUP BY yearstep,monthstep
ORDER BY yearstep,
monthstep;
END;
ELSE
IF ( v_granularity = 'Year' ) THEN
BEGIN
SELECT COUNT(*) DisplayCount,
yearstep
FROM MyTable
GROUP BY yearstep
ORDER BY yearstep;
END;
END IF;
END IF;
END;
I hope it helps youi

       )Can someone help me...maybe point out what I'm doing wrong.
Note: I also tried creating this query in Microsoft Query (the simple way) and when I first create it...it works...But then if I go back in to edit the query, and refresh the query or try to Return data to Excel, it gives me a ORA-00936 error message.
Why it works when I first create the query in Excel, I don't know. But I have to validate the queries I'm creating (SQL or not) and I can't validate it if every time I go into edit the query (which may have to happen; that's why I have to fix this before I can submit my validation).
Anyway, any help would be greatly appreciated.

Okay, I know I'm replying to my own threads here...but I want to add a little bit more information again.
I was successful in figuring out that changing the :criteria to a ? worked.
I tested this on 1 criteria at a time. Adding one more scenario ? at at time.
It only worked up until about 3 scenarios of each criteria.
Then when I refreshed the query in Microsoft Excel Query, I got an "out of memory" error, and then it ended up just erasing the SQL I had been using.
Here's the SQL I had where it gave me this error. Am I possibly just making Excel work too hard? It just doesn't make sense because Toad for Oracle handled it in like 4 seconds. Which brings me back to an intial question I had. Can Excel use Toad for Oracle somehow?
Here's the code:
SELECT a_compl_summary.incident_number, a_compl_summary.case_number,
       a_compl_summary.part_sequence, a_compl_summary.part_number,

Oracle Integration Adapter for SAP R/3

I am working with a customer implementing Oracle EBS Release 12.2.
The customer has implemented SAP for financial modules and the oracle solution considers an EBS - SAP Integration for Receivables. Does anyone have any experience integrating Oracle EBS Receivables with SAP? Can you give us some guidance regarding EBS - SAP Integration best practices?
We have found a paper regarding Oracle Integration Adapter for SAP R3. We would like to have some information about what are the Oracle products we can integrate with SAP using Oracle Integration Adapter for SAP R3.
In case Oracle EBS can integrate with SAP using Oracle Integration Adapter, we would like to know if anyone has experience integrating Oracle EBS Receivables with SAP using Oracle Integration Adapter for SAP R3 for AR transactions and Receipts?
Any help would be very much appreciated.

Thank you veyr much Manoj for your reply. I just tried it now buit no fruits.
I wonder if it can really be due to privileges given to my account, which allows to connect thru SAP Front-end but does not allow to connect by any other means. I can not think of any other possible reason.

SQL to Oracle Migraton - Unable to create source model in Migration Workben

We are trying to use Oracle Migration Workbench utility to transfer data from SQL to Oracle. when we start creating the source model we get the following error :-
failed to load source model ora-01401 inserted value too large for column.. this is the error at the ss2k_syslogins table. this is a logical model creation from sql server db.
In case if this is a data issue with the syslogins table/view, is there any way to overcome this or whether we can do any settings at Workbench Level to overcome this..
Thanks in advance,
John.

I think I figured it out.
1 - I used the Migration Work Bench that came with the 9.2.0.1 client - BAD IDEA.
2 - I down loaded the OMWB (10.x) - GOOD IDEA. I also downloaded the plugins so that the versions would match each other. Get rid of any existance of the 'old' OMWB directory under the OracleHome, so as not to get confused.
3 - I realized that you just extract the OMWB.zip file to the C: drive like some third world DOS application, so it won't show up in under your start menu.**
**I find this kinda cheesy that the Oracle installer is not involved here to add it to the Oracle Configuration and Migration menu in start up. I suppose you can copy the unzipped struture over top of the existing clint directory structure, but still dumb.
3 - The other odd piece, you down load the plugin as a zip (and not a jar), BUT DON'T UNZIP IT!! Rather place it in the ..\plugins directory, underneath wherever you unzipped the OMWB, and RENAME IT with a .JAR extension (again don't unzip).
4 - Make a shortcut on your desktop to the omwb.bat file (from where ever you unzipped the OMWB product)
5 - Fire up that icon and the product will look at the new .JAR in the plugin folder and 'tada', you have OMWB with your specific database plugin available.
The new product didn't hang for me. Now I just need to figure out how port this into a shema name OF MY CHOSING, and not the generic OMWB_Login1 that it created.
I f anyone has info on that, let me know.... I think its in the destination creation (step two of the whole process).

thanks for your answer, but I asked to use sql loader instead of the external table, which so my question is why can not the epochtime converted to datetime, if there is no way to convert a datetime epochtime using sql loader, so I'm required to use the external table. thank you.
This is my error log:

How to validate XML Digital Signature with XML DB (o PL/SQL) in Oracle 11g

Hi,
Do you know if there is possibility to validate XML Digital Signature using XML DB (or PL/SQL) in Oracle 11g?
Let say I have CLOB/XMLType containing Digitally Signed XML, and I want to validate, that thsi is proper signature. I also have public key of signer (I could store it in CLOB or file or Oracle wallet).
Is it possible to do?
If there is need to install additional component - then which one?
Regards,
Paweł

Hi,
this is what i got from someone...
but the links he gave are not opening up...
u have to place a picture there and have to load the digital signatures as Jpegs on to the server to OA top

Oracle.integration.platform.blocks.sdox.WLSSDODynamicStubHelper

Hi All,
I have developed an ADF-BC Service and created service interface in it. And trying to deploy in Admin server but getting the following error:
[01:44:28 PM] Weblogic Server Exception: weblogic.application.WrappedDeploymentException: oracle.integration.platform.blocks.sdox.WLSSDODynamicStubHelper
[01:44:28 PM] See server logs or server console for more details.
[01:44:28 PM] weblogic.application.WrappedDeploymentException: oracle.integration.platform.blocks.sdox.WLSSDODynamicStubHelper
Do we need SOA server for this to deploy or can deploy on Admin Server also? Please help me
Regards,
Ramesh.

I am using FusionOrderDemo_R1PS4 for FOD, but I am trying to build it on SOA_11.1.1.6.0_GENERIC_111217.1257. I know that there could be some mismatch, but I want to fix them.
Any way to fix this without using SOA earlier version?

Embedded SQL against Oracle Question

Software: Forte 3.0.J.
Server Platform: HPUX 10.2
Database: Oracle
Problem Description: During the course of development, I ran into a
problem using multiple columns in an sql UPDATE/SET statement. I was trying
to update a.COLUMN_1 and a.COLUMN_2, which constitute part of the primary
key of associative TABLE_A (a). In order for me to make the update, I
needed to use the existing value of a.COLUMN_1 to lookup the new b.COLUMN_1
in TABLE_B (b). Where a.COLUMN_1 = b.RELATED_COLUMN_1, I am able to find
each b.COLUMN_2 that correspond to each a.COLUMN_2.
I was able to resolve the issue by separating the two columns so
that each had it's own select statement. Theoretically, it appears that
this shouldn't work, because the SET statement for a.COLUMN_1 would cause
the a.COLUMN_1 reference in the select statement of a.COLUMN_2 to be
overwritten.
In spite of this, I tried it, and it worked. I would like to
understand why the sql works, and how sql actually executes the statement.
Here is the sql:
UPDATE TABLE_A a
SET a.COLUMN_1 =
(SELECT DISTINCT b1.COLUMN_1
FROM TABLE_B b1
WHERE b1.RELATED_CASE_ID =
a.COLUMN_1 AND
b1.RELATED_COLUMN_TYPE_CD = 'NEPHI'),
a.COLUMN_2=
(SELECT DISTINCT b2.COLUMN_2
FROM TABLE_B b2
WHERE b2.RELATED_COLUMN_1=
a.COLUMN_1 AND
b2.RELATED_COLUMN_TYPE_CD = 'NEPHI' AND
b2.RELATED_COLUMN_2= a.COLUMN_2)
WHERE a.COLUMN_1 = 100
The table structure is as follows:
TABLE_A: (primary keys are bolded) This is an associative table.
Column_1 and Column_2 comprise the pk of one table; Column_3 and Column_4
comprise the pk of another table. Assume that the Column_1 and Column_2
values replacing the original values already exist in the parent table of
which they form the pk).
COLUMN_1
COLUMN_2
COLUMN_3
COLUMN_4
COLUMN_5
TABLE_B: (primary keys are bolded) This is a reference table.
COLUMN_1
COLUMN_2
RELATED_COLUMN_1
RELATED_COLUMN_2
RELATED_COLUMN_TYPE_CD

If you do an explain plan or set autotrace on against this update statement,
you'll find that the select operations are actually executed first by Oracle
- I believe because of the nature of the transaction. Thus, no problem.

Learning PL/SQL in Oracle 10G XE

Successfully installed Oracle 10G XE on my desktop. I'm a newbie Oracle user who wants to learn PL/SQL through Oracle 10G XE.
Is this possible? Hope you can give me tips and advice on how I would start with this?
Thanks!

Certainly possible. I would suggest you crack open the PL/SQL Users Guide. DO you have previous programming experience? If so, looks at the examples.

MS SQL to Oracle Integration.
