Sender JDBC Adapter with Mutiple SQL Database Tables.

Hi All,
My requirement is SQL->PI7.0->BI.
I have a plan to go with the senario like this : JDBC sender->SAPPI->ABAP Proxy.
And also I need fetch the data from more than 10 data tables with different database tables with key fields.
Could you please suggest me, How to extract all tables data to SAP PI System. Either need to go with Stored procedures or Any Join conditions or each table like as one Interface.
Please provide me your suggestions.
Regards,
Chandra

Hi ,
Chandra ,
Best way is Database Views
Involve a Database guy in your scenario : Tell DBA the fields required , tell DBA the PrimaryKey and ForeignKey Relation Between All your 10 Tables.
DBA will create a View for you on 10 Tables.
So in Ur SELECT Query . you can write simply
Select * from <ViewName>;
And One more thing to Tell DBA to create a UPDATABLE VIEW not only READ-ONLY View.
By this way you can way you can Update VIEW also in UPDATE QUERY of sender Adapter...

Sender JDBC Adapter : Fetch records from multiple tables

Hi Friends,
I am using sender JDBC adapter to select few records from DB2 database table.
This scenario is working fine.
Now my requirement is to fetch records from 3 tables. These table are independent to each other. There is no primary key or foreign key.
Please let me know how to write the sql in sender JDBC adapter to fetch records from these 3 tables.
Thanks,
Sandeep Maurya

hi sandeep...
if the tables are completely independent and do not share any primary / foreign key relation ship...
why dont u think towards creating a seperate interface for each of them..
or if u still want to select from multiple table at once..the best way would be to write a stored procedure on the sender side which do all the fetching n processing and pass the final resultset to PI
or u can think towards fetching the data from 1 table and then in UDF do lookup from other tables..which again is tricky and performace intensive

Sender JDBC adapter : Update SQL Statement : stored procedure

Hi,
Can we use a stored procedure in the sender jdbc adapter in 'Update SQL Statement'.
The problem i am facing is like, we are selecting data from two tables in 'SQL statement for query' and then in 'Update SQL Statement' , we need to delete that data from these two tables.
Please let me know if it is possible.
Thanks,
Rohit

you can use a Stored procedure in the
Query SQL Statement
You have the following options:
· Specify a valid SQL SELECT statement to select the data to be sent from the specified database.
· Specify an SQL EXECUTE statement to execute a stored procedure, which contains exactly one SELECT statement.
The expression must correspond to the SQL variant supported by the relevant JDBC driver. It can also contain table JOINs.
so have your whole select and update as part of this single Stored procedure

Sender JDBC adapter donot want to update database..

Hi,
We have JDBC to RFC scenario. In This we need to read only database table , we should not update it. As in sender JDBC adapter configuration Update SQL Statement is mandatory, so what needs to be done in this case?

Hi,
In place of the SQL statement, you can also enter <TEST>. Once the data determined from Query SQL Statement has been successfully sent, the data in the database remains unaltered.
This is recommended if the data has not only been read, but also changed by a stored procedure entered under Query SQL Statement.

Sender JDBC Adapter - Stored procedure

Hello all, I just read a lot of topics in this forum about this subject.
I found two indications in contracdictions in the documentation :<a href="http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/frameset.htm">Configuring the Sender JDBC Adapter</a>
1. Concerning Query SQL Statement
You have the following options:
● Specify a valid SQL SELECT statement to select the data to be sent from the specified database.
● Specify an SQL EXECUTE statement to execute a stored procedure, which contains exactly one SELECT statement.
2. Concerning Update SQL Statement :
This is recommended if the data has not only been read, but also changed by a stored procedure entered under Query SQL Statement.
It is ambigous, isn't it ?
My question is simple :
Does somebody already use Sender JDBC Adapter with Stored procedure as Select statement including many steps :
- update actions on database
- select query to return data to XI adapter
(Update statement stay empty or with value <TEST>.
To provide more information, I have a reference table to read. But this reference table must be updated by a stored procedure before being able to be read accordingly.
So As I can't do both process with Sender Adapter (call a procedure and execute a select statement) => I want to include both actions (updates and select) in an alone stored procedure.
Could I get wanted data as a resultset ?

Hi,
>>Update statement stay empty or with value <TEST>.
It should be <TEST> if you do not want an Update to happen.
Regarding Sender JDBC adapter with stored procedures, which DB are you trying to access. Sender JDBC adapter does not support Oracle Stored Procedures as they return Cursors and Sender JDBC adapter can deal with only Resultset.
As for executing both Update and Select in the SP, though I havent tried, this should surely be possible.

Sender JDBC adapter SELECT / UPDATE issue - updates more rows than selected

Hi,
We have configured a Sender JDBC Adapter to poll records from an Oracle table based on a flag field and then update the flag for the selected records. When tested in DEV and QA environments (where test data comes in intermittently and not in huge volumes), itu2019s working fine.
Both SELECT and UPDATE queries written in the Sender JDBC adapter are getting properly executed and are changing the status of the flag for the selected records from Y to N once read from the database.
select * from <table> where flag = 'N'.
update <table> set flag = 'Y' where flag = 'N'.
But in the PROD environment (with records getting updated in the database every second), after XI executes the SELECT query and just before the UPDATE query is executed, new records come into the Oracle table with status flag 'N". So when the UPDATE query runs just after the SELECT query, then these unselected records also get updated to 'Y'. Thus these records never get into the resultset and hence XI and thus remain unprocessed.
So when XI does a SELECT and UPDATE on the Oracle DB table and concurrently there is an INSERT happening into the table from the other end, the JDBC sender adapter is picking up a certain number of records but updating the status of more records than it picked up.
So how does XI deal with such a common scenario without dropping records?
Thanks,
Vishak

The condition being checked is the same for both SELECT and UPDATE statements.
Initially I tried setting transaction isolation levels on the database to repeatable_read and serializable but it was throwing me a java.sql.SQLException error saying that these transaction levels were not valid.
I asked for these transaction level permissions for the XI user from my DBA but the DB I am accessing provides only a view into other databases and so it's not possible.

Executing an Oracle Stored Procedure from Sender JDBC adapter

I could really use some help from someone who had done this before.
I've read the help about using the JDBC sender adapter, but it's not helping enough.
I found this line: "Specify an SQL EXECUTE statement to execute a stored procedure, which contains exactly one SELECT statement.
The expression must correspond to the SQL variant supported by the relevant JDBC driver. It can also contain table JOINs."
That's definately what we want to do, but we can't figure out the syntax.
The procedure in oracle looks like this:
CREATE OR REPLACE PROCEDURE test_ref_cursor
( cur_generic IN OUT result_sets.cur_generic)
as
BEGIN
Open cur_generic for
select
 proposal_number,
 to_char(sequence_number),
 column_name,
 column_value,
 update_timestamp,
 update_user
 from
 coeus.sap_test;
END test_ref_cursor;
And we have tried every kind of statement we can think of, but the file adapter always gives us an "invalid sql statement" error.
Does anyone know what syntax we need to put in the "Query SQL Statement" in the JDBC sender adapter in order to call this procedure? Or is there something wrong with the procedure that is causing the error?
I will absolutely return and give points, but PLEASE read my whole post before answering and do not just link me to or quote the help for configuring a sender JDBC adapter or blogs that are about the JDBC adapter in general but do not deal with the issues I am having. Thank you.

Hi Vanda,
Unfortunately, the sender JDBC adapter does not support Oracle's store procedure/function. Unlike stored procedures from other database vendors, Oracle returns a cursor, not a resultset. The sender JDBC adapter must send a resultset to XI.
There are 2 possible ways you can accomplish this:
1. Use BPM and call the Oracle stored procedure using a receiver adapter via a asynch-synch bridge.
2. Develop a user-module for the adapter, which can be used with a sender adapter.
Thanks

SENDER JDBC ADAPTER ERROR

Hi all,
We are having an extrange problem. We are trying to read some info from an oracle Database, but we have always this error :
Error: SQLException during query 'SELECT * FROM XX': java.sql.SQLException: ORA-00942: table or view does not exist: SQLException: ORA-00942: table or view does not exist
And WE have checked it, and the table is there. To understand what is happening we try with another table and it works, we have compare both an has the same features.
Any Ideas?

Hi,
This is the format in which your Data polled from the DB wiill be created,
<resultset>
<row>
<column-name1>column-value</ column-name1>
<column-name2>column-value</ column-name2>
<column-name3>column-value</ column-name3>
</row>
<row>
<column-name1>column-value</ column-name1>
<column-name2>column-value</ column-name2>
<column-name3>column-value</ column-name3>
</row>
</resultset>
Resultset is to be replaced by your DT / Message Type name.
In the Sender JDBC adapter, give the Document Name as the Message Type name and the Document Namespace as the Namespace of your Message Type.
Is this how you have created the source structure?

Bhavesh

Stored procedure in Sender JDBC Adapter

Hi All,
My Scenrio goes like this ...
Stored Procedure(SQL Server) --- PI -
File
I need to write the results of stored procedure to File.Here I don't need any mapping.So how many DT , MT and MI need to be created?
The interface need to run by 6AM from Monday to Thrusday, how can i achieve this ?
Stored Procedure has only select statement and no Update statement , but it takes Date as Input parameter , so what i need to provide in sender JDBC adapter.
Thanks,
Monish

Hi Monish,
As per your requirement it is JDBC to File. Please be careful with the structure to be created for sender JDBC. I am unable to understand why you donot require a mapping for this. How XI will send the data to a file then.As per my knowledge if it's file to file and just pick and drop then we can neglect IR and go for ID.But here you are working with JDBC and File so you will be in need of it.
IR:
DT: 2
JDBC_Sender_DT
File_Output_DT(Optional)
You can use the JDBC sender data type structure for File output also.
MT as per your DT
MI:2
Outbound MI: JDBC structure
Inbound MI : File structure
MM: 1
IM: 1
ID as similar to other scenarios.All 1 objects for RD,ID,Sender Agreement and Receiver Agreement.
Sender JDBC channel:
Query: Select * from table where date
But I have a query how are you providing date in input paramerter.It will be dynamically entered into the query right.
You can mention the Avalibility planning for your interface to work in RWB.
Go to RWB>Component Monitoring>Adapter Engine->Communication Channel Monitoring>Avaliablity Planning
Please explain.

Nutan

Sender JDBC Adapter and Synchronous Interfaces

Hello
I have a Oracle/JDBC -> XI -> ECC/RFC scenario. The communication mode is Synchronous.
In the Oracle database I have a table with a "STATUS" field. When JDBC Adapter Sends the rows from this table to the Integration Engine, it updates the "STATUS" from "G" (GENERATED) to "R" (READ).
The response from the RFC contains for each row sent to RFC a "STATUS_from_RFC" field, that I would like to use to update Oracle STATUS field to "S" (SUCCESS) or "E" (ERROR).
Can the Sender JDBC Adapter use the response from the Synchronous RFC to update Oracle "STATUS" field itself ?
Or do I need a Receiver JDBC Adapter? In this case, I have to use asynchronous communication and BPM, ok ?
thanks
Julio

Bhavesh,
>>>But, the online help states it supports QOS of BE and so it does support Synchronous Processing.
Even File adapter has QOS of BE
To my understanding response back is possible only if it is PUSH + Sync
Adapters PUSH + Sync
HTTP
SOAP
RFC
XI
etc...
For the above response is possible
Adapter PULL + Sync
File
JDBC
etc..
In general there can be a response if there is a request. In the case of File and JDBC there is no request message coming to the adapter, its the adapter which is actually requesting.
This is just an idea and my understanding.. might not be true If possible do try it and let everyone know I will also give it a try when time permits
Thanks,
Prakash

Sender JDBC Adapter Supports Stored Procedures????

Dear All,
I was trying to use the Sender JDBC adapter to call the Stored procedure in the Sender JDBC adapter is possible to do this???
I don't think Sender JDBC Adapter is supported to execute the Oracle Started Procedures. With my understanding only the Receiver JDBC Adapter will supported for the Stored Procedures using the message mapping Action = EXECUTE and Table = DBO.EmployeeMasterTable.
Please let me know how to achieve the below scenario.
My Scenario JDBC to RFC
Query SQL Statement:
select * from dbo.emp where flag = 'Insert' or flag = 'Update' or flag = 'Delete'
Update SQL Statement:
UPDATE dbo.emp SET flag = null WHERE flag IN ('Insert', 'Update');
DELETE dbo.emp WHERE flag = 'Delete';
In the my update statement I need to update few data flag with Insert , Update and need to delete the of the old records as mentioned above the query.
In the response mapping I am using the Action = INSERT and Table = emp.
Thanks,
Jane F.

Hi Jane,
>>My requirment is to select from the DB and update and delete needs to be done. How I need to call this stored procedure in Sender JDBC adapter.
An example of SP call is mentioned in the previous note Note 941317 - XI / PI JDBC Adapter: Known Problems / Incompatibilities
SP Code
          ---------- pkg1 ----------
CREATE PACKAGE pkg1 AS
TYPE numset_t IS TABLE OF NUMBER;
FUNCTION f1(x NUMBER) RETURN numset_t PIPELINED;
END pkg1;
CREATE PACKAGE BODY pkg1 AS
-- FUNCTION f1 returns a collection of elements (1,2,3,... x)
FUNCTION f1(x NUMBER) RETURN numset_t PIPELINED IS
BEGIN
    FOR i IN 1..x LOOP
      PIPE ROW(i);
    END LOOP;
    RETURN;
END;
END pkg1;
In sender channel mention
>> SELECT * FROM TABLE(pkg1.f1(5));
>>Is this need to be in the one stored procedure right. Can ou let me know how it should be handled in JDBC Adapter.
Yes it shoudl be a single SP. Mention a select statement as given in above example.
What is your Oracle version?

Transaction handling in sender JDBC adapter

Hello,
In a scenario where a third party application updates a field (counting it up) and we pick up these counts and zero out the field with the sender JDBC adapter, we would like that the third party application is not able to update while the JDBC sender adapter is processing.
We were under the assumption that the select and update statements of the sender JDBC adapter where executed within the same DB transaction and set the isolation level to "repeatable read" to make sure the third party app. could not update while the adapter is processing.
This had no effect.
Do the select and update statement occur within the same transaction?
Thanks,
Dan
Edited by: Dan Hansen on May 5, 2008 9:58 AM

Thanks for the answers so far, I have looked through this and can find no reason why the current set up with "repeatable_read" should not work... a little more info. We are running against a MSSQL 2005 database using a table with the following structure.
CREATE TABLE [dbo].[OPERATION] (
     [WERKS] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
     [AUFNR] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,

     [RSTZE] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY]
GO
We read information about the quantities per primary key combination with the select statement where the ZSTATUS field is "CONF" and then zero out the quantity field and set the ZSTATUS to CONF2SAP with the update statement.
Another app counts up the quantities and sets the ZSTATUS to CONF as needed.
Sometimes we see that we miss a count because we read before someone has increased the quantity but update back after they did and thereby zero out their entry.

Questions about sender JDBC adapter

Normally we use sender jdbc adapter in this way:
query statement:
SELECT * FROM table WHERE processed = 0
update statement:
UPDATE table SET processed = 1 WHERE processed = 0;
The update statement will be executed after the message has been successfully sent to XI.
My questions is that what will happen in this scenario:
A new record (processed=0) is added to the database table when a message is sent to XI with query statement but not finished?
After the message is sent to XI successfully, XI will execute the update statement. Then the new added reocrd will also be updated to 1 although it hasn't been sent to XI.
Does XI have some control or special check for this issue?
Regards
Hui

Hi,
this can be handled by the ISOLATION LEVEL FOR TRANSACTION setting of the sender Jdbc adapter.
make the transaction handling to SERIALIZABLE or REPEATABLE READ and then until the data is not read from the JDBC adapter and it is not updated by the UPDATE statement , no new rows will be allowed to be inserted into the database. The database will be write locked.
http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/content.htm
Isolation Level for Transaction
There are different levels of database transactions known as isolation levels. The isolation level determines how transactions running in parallel influence each other. The options correspond to the JDBC constants:
 Default (default setting of the respective database)
 None
 read_uncommitted (weakest setting)
 read_committed
 repeatable_read
 serializable (strongest setting)

Error in calling stored procedure in sender JDBC adapter

Hi Experts,
I am working on MySQl to SAP scenario. I have to use stored procedure in sender JDBC adapter.
I am calling SP as fallows: execute proc_dtdc_booking_interface_sd
But it returned following error,
Database-level error reported by JDBC driver while executing statement 'execute proc_dtdc_booking_interface_sd'. The JDBC driver returned the following error message: 'java.sql.SQLException: Unknown prepared statement handler (proc_dtdc_booking_interface_sd) given to EXECUTE'. For details, contact your database server vendor.
the way i called SP is correct ??
please suggest me how to resolve the issue ??

JDBC adapter - no UPDATE to database

Hi,
I have the scenario ABAP Proxy to XI to JDBC to read some data from a database and return some info back to BW. Is it mandatory to UPDATE the selected records in some way or can the UPDATE part of the adapter be disabled by putting something in the UPDATE parameter on the comm channel ?
Cheers
Colin.

Hi Colin,
if you are talking about a sender JDBC adapter: you can put <TEST> in the update statement.
See this snippet from the help:
Update SQL Statement
You have the following options:
Enter a valid SQL statement that is to be applied to the database once the data (determined from the Query SQL Statement) has been successfully sent to the Integration Server/PCK.
It must be an INSERT, UPDATE, or DELETE statement.
In place of the SQL statement, you can also enter <TEST>. Once the data determined from Query SQL Statement has been successfully sent, the data in the database remains unaltered.
This is recommended if the data has not only been read, but also changed by a stored procedure entered under Query SQL Statement.
http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/content.htm
If you want to synchronously call a receiver JDBC adapter, i think you can use action=SELECT without an update.

Christine
