Hi Guys,
This is a first.... Can I ask the original poster to please sign up with a new account and repost? At this point we don't know who you are.
Our developer have been made aware of this problem and should be looking into shortly.
I am going to lock this post also so the Real Gary doesn't get a bunch of E-mails.
Thank you

You mean when you click on the hyperlink you want that row to disappear from the page, but not delete the row from the database until a commit/submit button is pressed?
Personally, I think I'd prefer that you have a delete checkbox next to every row and NOT remove them from the display if I was a user. You give your users a chance to change their mind about their choice, and when they're done they can see exactly which rows will be deleted before they commit.
You know your problem, of course, so you might have a good reason for designing it this way. But I'd prefer not removing them from the display. JMO - MOD

How to get multiple rows from database table?

hello !
I need to get multiple rows from a OLEDB database table and display them on a table object.
I did "Wrap in subfrom" on the table, set subform of the table to "flowed", and checked "Repeat row for each data item" of Row1 of the table.
But I can get only one row on the table object.
I need your help.
Thanks

Hi,
best practices when deleting multiple rows is to do this on the business service, not the view layer for performance reasons. When you selected the rows to delete and press submit, then in a managed bean you access thetable instance (put a reference to a managed bean from the table "binding" property") and call getSeletedRowKeys. In JDeveloper 11g, ADF Faces returns the RowKeySet as a Set of List, where each list conatins the server side row key (e.g. oracle.jbo.Key) if you use ADF BC. Then you create a List (ArrayList) with this keys in it and call a method exposed on the business service (through a method activity in ADF) and pass the list as an argument. On the server side you then access the View Object that holds the data and find the row to delte by the keys in the list
Example 134 here: http://blogs.oracle.com/smuenchadf/examples/#134 provides you with the code

How to delete a row from database table in facade client

Hi all,
I followed the tutorial in creating a persistence entity from database table, then a session facade. Then I followed the tutorial to create a sample client to test the model. In the session facade, I could use persistEntity method to insert a record to the database. I am just thinking of an extension to the tutorial, i.e., being able to delete the record too. So I created a new method removeEntity in the session facade
public void removeEntity(Object entity) {
entity=em.merge(entity);
em.remove(entity);
em.flush();
and called it in the sample client. It was executed without any error, but the record in the table still exists.
I tried to look around for a solution, but I did not find one. Would anybody here please help out? Many thanks in advance!

How to create a stored procedure and use it in Crystal reports

Hi All,
Can anyone explain me how to create a stored procedure and use that stored procedure in Crystal reports. As I have few doubts in this process, It would be great if you can explain me with a small stored proc example.
Thanks in advance.

If you are using MSSQL SERVER then try creating a stored procedure like this
create proc Name
select * from Table
by executing this in sql query analyzer will create a stored procedure that returns all the data from Table
here is the syntax to create SP
Syntax
CREATE PROC [ EDURE ] procedure_name [ ; number ]
    [ { @parameter data_type }
        [ VARYING ] [ = default ] [ OUTPUT ]
    ] [ ,...n ]
[ WITH
    { RECOMPILE | ENCRYPTION | RECOMPILE , ENCRYPTION } ]
[ FOR REPLICATION ]
AS sql_statement [ ...n ]
Now Create new report and create new connection to your database and select stored procedure and add it to the report that shows all the columns and you can place the required fields in the report and refresh the report.
Regards,
Raghavendra

How to generate .PRN file from a ReportDocument object in Crystal Reports 10.

Hi,
I have reports created in Crystal 10 version. From the VB .Net code I am able to load the report to ReportDocument object and able to print it to the local printer. Now I need to generate .PRN file of the report for faxing purpose.
Can anyone help me one this?.
Thanks,
Srini.

Hi Joanne,
Boxes do not actually have a 'name'. When you add a Box in a report, it will be called 'Box 1' by default. And the only place this name is visible is under the Report Explorer.
Or do you mean to say 'Text Object'?

How to eliminate inserting Duplicate rows into database using JDBC Adapter

File->Xi->JDBC
In above Scenario if the file has two rows their values are identical, then how can we eliminated inserting Duplicate rows into database using JDBC Adapter

Database is a consumer of a SERVICE (SOA!!!!!!).
Database plays a business system role here!!!!
Mapping is part of an ESB service
Adaptor is a technology adapted to ESB framework to support specific protocol.
ESB accomplish ESB duties such as transformation, translation, routing. Routing use a protocol accepted by the consumer. In a JDBC consumer it is JDBC protocol and hence it a JDBC adaptor.
There is clear separation on responsibilities among business system and ESB. ESB do not participate in business decision or try to get into business system data layer.
So who ever are asking people to check duplicate check as part of mapping (an ESB service) may not understand integration practice.
Please use an adaptor module which will execute the duplicate check with business system in a plug and play approach and separate that from ESB service so that people can build integration using AGILE approach.
Thanks

How to select rows from database like 10 to 20 etc

Hi Experts,
I want to select rows from database like row number 10 to row number 20.How could it be done?

HI,
   First get the data into the INTERNAL TABLE from the FLAT FILE and read the internal table using the index.
    ex: 1) Read table ITAB index 10.
          2) Read table ITAB index 20.
or use as said by Srinivas Gurram, to get the range of records using where condition to the loop.

How to copy file to another server from database using FTP in oracle

Cannot be determined via the FTP server's return code. Which means parsing and checking the text response from the server to the command. And this vary from server to server.
But the basics were quite easy to code. The entire package is 500 lines, includes comments and blank lines for formatting, and supports the basic FTP client command set. Not really a complex piece of software to write - but I found that many developers seem to think that writing network socket software is complex. Not really the case...Mine's a big larger, but incorporates functionality similar to what Chris provided in his, such as being able to use SQL to query a remote file using pipelined functions, or functionality to write the results of a query directly to a remove file.

How i can make multilanguage application .. take his vlues from database

How i can make multilanguage application .. take his values from database
and can change labels of massages , buttons ,text fields and name of columns in run time
in jdevelpoer11g
great thank

Hi,
I think that there is not a standard support for retrieving multilanguage texts from database in ADF. What we did is to implement our own ResourceBundle that retrieves the translated text from custom database tables. We also introduced a cache for optimizing the access to the translations.
I hope this can help,

Use Preparedstatement to delete several rows from database

Hello everyone,
I am trying to delete multiple rows from database at one time using Preparedstatement.
It works well when I tried in SQL directly,the sql query is as follows:
delete from planners_offices where planner ='somename' and office in ( 'officeone', 'officetwo', 'officethree')
I want to delete those 3 rows at one time.
But when I am using preparedstatement to implement this function, it does not work. It did not throw any exception, but just does not work for me, the updated rows value always returns "0".
Here is my simplified code:
PreparedStatement ps = null;
sqlStr = " delete from PLANNERS_OFFICES where planner = ? and office in (?) "
Connection con = this.getConnection(dbname);
try
//set the sql statement into the preparedstatement
ps = con.prepareStatement(sqlStr);
ps.setString(1,"somename");
ps.setString(2,"'officeone','officetwo','officethree'");
int rowsUpdated =ps.executeUpdate();
System.out.println(rowsUpdated);
//catch exception
catch (SQLException e)
System.out.println("SQL Error: " + sqlStr);
e.printStackTrace();
catch (Exception e) {
e.printStackTrace();
} finally {
this.releaseConnection(dbname, con);
try{
ps.close();
}catch (SQLException e){
e.printStackTrace();
rowsUpdated always give me "0".
I tried only delete one record at one time, "ps.setString(2, "officeone");", it works fine.
I am guessing the second value I want to bind to the preparedstatement is not right, I tried several formats of that string, it does not work either.
Can anyone give me a clue?
Thanks in advance !
Rachel

the setString function in a preparedStatement doesn't just do a replace with the question mark. It is doing some internal mumbojumbo(technical term) to assign your variable to the ?.
If you are looking to do your statement, then you will need to put in the correct of # of question marks as you need for the in clause.
delete from PLANNERS_OFFICES WHERE PLANNER = ? and office in (?,?,?)
If you need to allow for one or more parameters in your in clause, then you will need to build your SQL dynamically before creating your prepared statement.
ArrayList listOfOfficesToDelete ;
StringBuffer buffer = new StringBuffer("DELETE FROM PLANNERS_OFFICES WHERE PLANNER = ? AND OFFICE IN (");
for(int i = 0; i < listOfOfficesToDelete.size(); i++ )
   if( i != 0 )
       buffer.append(",");
   buffer.append("?");
buffer.append(")");
cursor = conn.prepareStatement( buffer.toString() );
cursor.setString(1, plannerObj);
for(int i = 0; i < listOfOfficesToDelete().size(); i++ )
    cursor.setString(i+1, listOfOfficesToDelete.get(i) );
cursor.executeUpdate() ;

Hi Mukesh,
I'd like to help, but can you clarify the issue? Are you asking how to print a photo from your printer? Also, can you confirm that your printer is a HP Deskjet Ink Advantage 3525 e-All-in-One Printer?
Thanks!

Custom database functoid to return multiple rows from database

Hi,
I have created a custom database fucntoid to execute a stored procedure which returns just single row from the database.But I could not manage to return multiple rows from the database.
Does anyone know how to return multiple rows from DB and create a node with that many occurrences in the target schema?
Thanks
JB

If you want to do this in messaging-only way without orchestration, then only option let to you is using .NET in BizTalk:
We had similar requirement with one of our clients, where they didn’t want to use orchestration (though we emphasised on less impact orch would have compared to manageability),
they still wanted to have pure-messaging only.
We extended the custom XslTransform component that ships with BizTalk SDK (<BizTalk installation directory>\SDK\Samples\Pipelines\XslTransformComponent)).
Created a custom disassembler pipeline component, used the XslTransform component from SDK to execute the map’s XSLT. Here we created a map with every links except the database ones. After executing the map, access the database, execute the store procedure
which returns more than one row/dataset, enrich the XSLT transformed message with the dataset from your database in disassembler.
Since .NET gives you the flexibility of access the dataset with more than one row, you can enrich the message in custom pipeline code.
Other option is code the message transformation completely in .NET code in custom disassembler by passing the received message to method/code which would code the map/enrichment.
While enriching you can execute the store procedure which returns more than one row/dataset, enrich the message further with the dataset from db.
