Two queries on same table in sender JDBC adapter

Hi all..
My requirement is as follows....
query a table and fetch rows where column Error="true"
If there are no records in the table satisfying the above condition ,i want to send a mail stating that there are not records with error flag set to "true"
But the problem is i wont get a message to PI if there are no records.
If i write a query to get the count of records where column Error="true",Obviously the count would be zero. Using this message from database i can send a mail.
Now please let me know if i can write both the queries in query SQL statement? if so howshould be the source structure?
Thanks
Ram..

Hello ram,
As far as i know it is not possible to use two different SQL statements in the sender adapter, though you can try with the join statement.
For further information refer this discussion

Read data from 3 tables in sender JDBC Adapter

Hi All,
I doing a scenario JDBC to IDOC I need to read 3 tables of ORACLE. how JDBC sender adapter will retrieve data from more than 3 ORACLE tables and also i need to update control status fields of these tables.
Please provide me the syntax for the select and update.
Thanks in Advance
Regards,
Nisha

Hi,
Select Syntax:- select Table1.Field1, Table1.Field2, Table2.Field3, Tabl2.Field4
From Table1 , Table2 where Table1.Field1 = Table2.Field3.
Similary use this Syntax for three Tables.
Update Syntax: -
In SP Check if Data Seletion is suceesful then Use the seperate Update statement for each table.
like Update Table1 set Field5 = 'Value'
where Field1 = 'Value'.
Also use the refernce link provided by Mr.Vinithra Iyangar.

Combine 2 Queries (from SAME table) into a SINGLE query

I have this two queries (from SAME table), and want to combine into one SINGLE query, how?
How can we use CASE WHEN THEN for such situation?
Query1:
SELECT t_inner.*,
Floor(t_inner.ProductiveTime/ 3600) || 'hr:' || LPAD(Floor(Mod(t_inner.ProductiveTime,3600) / 60),2,0) || 'min:' AS Productive_Time,
Floor(t_inner.OperatorDownTime/ 3600) || 'hr:' || LPAD(Floor(Mod(t_inner.OperatorDownTime,3600) / 60),2,0) || 'min:' AS OperatorDown_Time
FROM
(SELECT SYSTEMTYPE,
sum(TIME_TEST + TIME_STEP) AS ProductiveTime,
sum(TIME_IDLE) AS OperatorDownTime
FROM PFODS.PPL_TESTSYSTEMS_UTILISATION
WHERE (SYSTEMTYPE = '0005-072')
AND (TS_START >= to_date('13/01/2014', 'DD/MM/YYYY'))
AND TS_End <= to_date('17/01/2014', 'DD/MM/YYYY') + 1 + (1/1440) +(59/86400)
AND MONO != '9999999999'
GROUP BY SYSTEMTYPE ) t_inner
Query 2:
SELECT t_inner.*,
Floor(t_inner.MachineDownTime/ 3600) || 'hr ' || LPAD(Floor(Mod(t_inner.MachineDownTime,3600) / 60),2,0) || 'min' AS MachineDown_Time
FROM
(SELECT SYSTEMTYPE,
sum(TIME_IDLE) AS MachineDownTime
FROM PFODS.PPL_TESTSYSTEMS_UTILISATION
WHERE (SYSTEMTYPE = '0005-072')
AND (TS_START >= to_date('13/01/2014', 'DD/MM/YYYY'))

GROUP BY SYSTEMTYPE) t_inner
see http://postimg.org/image/koq87iyyz/ and
http://postimg.org/image/fv3zxa38n

with the first query,
SELECT t_inner.*,
Floor(t_inner.ProductiveTime/ 3600) || 'hr:' || LPAD(Floor(Mod(t_inner.ProductiveTime,3600) / 60),2,0) || 'min' AS Productive_Time

AND MONO != '9999999999'
GROUP BY SYSTEMTYPE) t_inner
it gives output as from
http://postimg.org/image/koq87iyyz/
with the second query,
SELECT t_inner.*,
Floor(t_inner.MachineDownTime/ 3600) || 'hr ' || LPAD(Floor(Mod(t_inner.MachineDownTime,3600) / 60),2,0) || 'min' AS MachineDown_Time
FROM
(SELECT SYSTEMTYPE,

AND MONO = '9999999999'
GROUP BY SYSTEMTYPE) t_inner
it gives output as from

I want to come those 2 queries into a single query, such that it gives both outputs as above. Let me know if you need any other information. thanks.

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

How to write two triggers on same table how it works?

Hello sir..
I have to write two triggers on same table for auditing different columns of different pages (may be different modules).
I will have an audit table in which i will insert data such as (user_id,module_id,column_name,old_col_val,new_col_ val,timestamp)
Now different users from different pages will update the data on same table may be same columns!
If we write directly, we will not be able to know which column is updated from different pages.
My question is how can we control the triggers to raise based on the pages

A trigger is executed whenever the table is inserted / updated / deleted (depend on trigger definition). It won't know what 'page' caused the operation. You can prepare a trigger for one page.
In order to fulfill your need, you need some way to tell the trigger where you are. There are many ways to accomplish this. Some possible methods are (please check the documents for detail)
DBMS_SESSION.SET_IDENTIFIER
DBMS_APPLICATION_INFO.SET_MODULEFor example, you can call DBMS_SESSION.SET_IDENTIFIER to set an ID from your page, and then call sys_context to read the ID back:
In Page:
exec dbms_session.set_identifier('Page1');
...In Trigger
pageid := sys_context('USERENV', 'CLIENT_IDENTIFIER') ;
...Note that if you use a connection pool, you may need to properly reset the session information before return, in order to avoid messing up the session information when the connection is used next time.

Two triggers on same table

Hi Friend.
I have to write two triggers on same table for auditing different columns of different users(may be different modules).
I will have an audit table in which i will insert data such as (user_id,module_id,column_name,old_col_val,new_col_val,timestamp)
Now different users from different modules will update the data on same table may be same columns from different front end forms!
If we write directly, we will not be able to know which column is updated by which user.
My question is in this case how can we control the triggers to raise differently?

You can use WHEN clause to fire a trigger only when some condition is true - you can check an user also,
look at simple example:
- suposse we have two users US1 and US2:

Synonym created.
SQL> insert into tab123 values( 1, 1, 1 );
1 row created.

Commit complete.We want a trigger that is fired only by user US1 and only after update of COL1 and COL2
(COL3 is ignored):
SQL> connect us1/us1
Connected.

(COL1 is ignored):

and second trigger only for user US2 and only after update of COL2 and COL3.
I hope this will help.

Sender JDBC Adapter Select/Update Issue

Dear All,
We have configured a Sender JDBC Adapter to Poll data from the DB2 tables. It is working fine and both the select and the update queries written are also getting properly executed and are changing the status of the flag from Y to N once read from database.
In the communication channel ->
select * from <table> where flag = 'N'.
update <table> set flag = 'Y' where flag = 'N'.
But I have one doubt after executing the select query some new data comes into the table of status flag 'N"., then will this unselected data will also be updated to 'Y' .
The question is while we do a select and update from XI on the DB table and at the same time there is an insert happening into the table from the other end how will the adpater behave in this case.Will it result in missing of some records during next select/update transaction from XI..
Your inputs will be appreciated.

Amit

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.

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,
>><i>Update statement stay empty or with value <TEST>.</i>
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 : 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

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 ,
     [VORNR] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
     [SSAVD] [datetime] NULL ,

     [LTXA1] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
     [ZCONFQTY] [numeric](18, 0) NULL ,
     [ZTIMESTAMP] [datetime] NULL ,
     [ZSTATUS] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,

     [ZSCRAPQTY] [numeric](18, 0) NULL ,
     [ZREWORKQTY] [numeric](18, 0) NULL ,
     [BEARZ] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
     [BEAZE] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
     [RUEST] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS 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.

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,
<i><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></i>
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

Configuring sender jdbc adapter

Hi all,
I have a requirement in which i have to select certain data from Oracle table and send it to an IDOC via SAP XI.
Problem is the select can happen from several tables. For example:
SELECT col1,col2,col3 FROM <tablename>
The <tablename> has to be variable. I do not need to do any JOIN. At a time select will be only from a single table i.e. col1, col2, col3 will all belong to the same table. But the adapter should poll multiple tables.
One more requirement is that once a particular record from a particular table has been selected some UPDATE also need to be done on the same record.
Pls can anybody provide me with a proper solution.
This requirement is a bit urgent.
Thanks in advance.
Regards
Neetu

Neetu,
You need to have the Table name dynamic in the Sender JDBC adapter's Select Query . This is not possible
You can consider using a Reciver JDBC adapter for which you can have a look at this blog ,
/people/bhavesh.kantilal/blog/2006/07/03/jdbc-receiver-adapter--synchronous-select-150-step-by-step
Or, you need a Separate sender JDBC adapter for every table to be polled.
>><i>One more requirement is that once a particular record from a particular table has been selected some UPDATE also need to be done on the same record.</i>
If you are using the Sender JDBC adapter, this would be simple using the UPDATE field of the Sender JDBC adapter .
If you are planning to use Receiver JDBC adapter, then You need a separate Send Step for this Update.
Better way to go would be to have separate sender JDBC adapters.

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.
