DB adapter or SQL statements

I have a simple requirement of developing web services to retrieve data from multiple tables of Oracle data base. I just wonder do we need to use DB adapter or SQL statements in the code. How the performance will vary with these two. The volume of data may be high. Any pointers will be appreciated.

Xi JDBC Adapter - Query SQL Statement & Update SQL Statement

Hi!
I configure the JDBC adapter sender (XI) to take data from Oracle database.
I set the Query and Update SQL Statement in the Processing parameters of the communication channel in this way:
Query SQL Statement :
SELECT * FROM XI_TABLE WHERE STATUS = 'WAIT' ORDER BY ROW_NUM
Update SQL Statement :
UPDATE XI_TABLE SET STATUS = 'DONE', DATE = SYSDATE WHERE STATUS = 'WAIT'
My question is :
If a new record with the field STATUS = 'WAIT' is added to the table (xi_table) during the time between the execution of the query statement and the start of the update statement, what will happen to that record during the update?
There is a way to avoid the update of that record? or to pass to the update statement only the record selected in the query statement?
Please, may you give me some example?
Thanks,
Francesco

hi,
did you check "Isolation Level for Transaction"
for the sender jdbc adapter?

Sender JDBC adapter -- Update SQL statement NOT work for the last record

I'm trying to use SAP XI to send records from Oracle database to As/400 using JDBC adapter. I've defined the communication channel for sender
(1) The "Query SQL statement" = select a_bgn_dt, a_end_dt from PX_PXXD WHERE NOT CU_ACTION_CD='P'
(2) The "Update SQL statement" = update PX_PXXD set CU_ACTION_CD='P' WHERE NOT CU_ACTION_CD='P'
Supposed that 3 records were retrieved from (1) and successfully updated to AS/400 but only the first 2 records in Oracle database are updated according to (2)
Any advise.
Pansy

Hi Pansy,
You select and update query is looking like wrong
kindly check below query,If you are using oracle
(1) The "Query SQL statement" = select a_bgn_dt, a_end_dt from PX_PXXD WHERE CU_ACTION_CD !='P'
(2) The "Update SQL statement" = update PX_PXXD set CU_ACTION_CD='P' WHERE CU_ACTION_CD !='P'
Thank you

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

Jdbc adapter log sql statement to file

How to examine the generated SQL statement in Receiver JDBC Adapter

I have been searching this forum how to display te generated sql statement (by the jdbc receiver adapter).
The only suggestion is to use RWB, but I was unable to find any details about how to do so.
Any help is appreciated

Hi,
To add, u can see the SQL Statements in Audit log of RWB.
Select Message Monitoring-> Adapter Engine. choose ur entry and click on Details option button, u can see the SQL Statements in Audit Log.

Update sql statement in sender/receiver jdbc adapter

Hi
What is the update sql statement we give in the sender/ receiver adapter when
1) SELECT statement was written in query sql statement
2) EXECUTE statement was written for a stored procedure in query sql statement
thanks
Anitha

> 1) SELECT statement was written in query sql statement
your table should have some value "already_processed" which prevents a second processing of that table.
the update statement sets that value.
> 2) EXECUTE statement was written for a stored procedure in query sql statement
the same as above.
when your stored procedure already does the update, then write a second stored procedure which does nothing.

JDBC sender adapter, ...Processing parameters, Update SQL statement

in JDBC sender adapter, ...Processing parameters, there is an Update SQL statement field, can u tell me ...why this is required,,,,,and in one of the example scenario...it was given as <TEST>..

Sudheep,
In the sender JDBC adapter you have the select query to select data from the database.
Let us summer 2 cases,
1. You have <test> in the UPDATE . In this case, during every polling interval the JDBC adapter will end up selecting the same data from the Database. This would not be needed in most f the cases. Why would you want to select the same data over an over again?
2. If you have an update Statement in the Update field you can make sure that the data selected in the selected statement is updated so that the same rows are not selected again.

JDBC Sender Adapter - SQL-Statement

Hi,
I'm using the JDBC-Sender-Adapter and need to use a SQL-Statement like this:
SELECT * FROM myTable WHERE myDate = <current_date>
Is such a dynamic-sql possible, or can I only use static sql-statements. And if yes how can I solve this problem.
many thx

Hi Werner,
inside the <b>Query SQL Statement</b> you can use <b>SQL EXECUTE</b>
which can execute a stored procedure
in which you can do
SELECT * FROM myTable WHERE myDate = <current_date>

JDBC Sender Adapter : java.sql.SQLException: Cursor state not valid.

Hello all,
We have configured JDBC Sender Adapter which fetches around 10K records with poll interval 1hr from DB2 System .
It was working fine,suddenly it started throwing an exception in Adapter Monitoring :
Error during conversion of query result to XML: java.sql.SQLException: Cursor state not valid.
It is not fetching any records.
Without changing any configurations when we tried to fetch to around 1000 records it's working fine.
For 10K records same exception persists
What could be the reason ?How to resolve this issue?
regards
GangaPrasad

Execute stored-prozedure in sql-statement in jdbc-adapter for sender

Hello,
in the sql-statement i call a stored procedure which makes following:
- doing a selcet
- update one field
- give a recordset back
In the update-field i write:
But in the adapter monitoring i become a sql-exception:
Error: SQLException during query 'EXECUTE st_enum_EAI_lokation': java.sql.SQLException: [SQLServer 2000 Driver for JDBC]No ResultSet set was produced.
I´m using sql-server.
So there is no resultset coming back...
The reason for the stored-procedure is that it is not allowed to make changes in a productive data-base directly by an update.
What´s the problem?
Thanks in advance,
Frank

Currently, the jdbc sender adapter cannot execute Oracle's stored procedure. Oracle's stored procedure cannot return a resultset, which is required by the jdbc sender adapter.
An adapter user-module is available for a sender adapter to execute Oracle's stored procedure.
If you are interested, I can send it to you.

Can sql statement be passed as input to Database Adapter?

Hi,
We have requirement to execute the sql statements using database adapter.
Pls let me know if it is feasible in BPEL using partnerlink copy operation of assign activity like we do for setting JNDI name dynamically.
Thanks ,

SQL Statement on JDBC Adapter

Hi all,
how can I see the SQL Statement which is made by the JDBC Adapter.
I have createt the XML Structure, but I want to know how PI (7.11) transformed the XML to SQL.
How can I trace the JDBC Adapter? Which configuration is neccessary? Where can I find the trace?
Thanks very much for your help!
