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

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.

(261936172) Q DBC Multiple rows from Database Control method?

Q<DBC> Can you give an example of returning multiple rows from a database?
A<DBC> A Database Control method can return multiple rows.
Assuming the SQL for the method can return multiple rows from
the database, what does the method return? It may return an
Array of Objects*, an Iterator (on a Collection of Objects*)
or a java.sql.ResultSet.
Attached is code that gives an example of returning multiple
rows (not the entire files, but text from them).

hi Keshav,
Earlier i was using same variable SEL in internal table and as a selection column as well. In that case, it was marking SEL as 'X' even when document was selected.
Today, i tried making selection column name as 'MARK' and internal table field name as 'SEL', it is working fine. I am able to read table control lines where MARK equals 'X'.

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

Returning Multiple Rows From DBAdapter Calling PL/SQL Procedure

Oracle XE 10g Express Edition
JDeveloper 11.1.1.2.0
WebLogic Server 11g
Guys,
I have a table of orders, which I need to interrogate, and pass back any matching rows which meet certain criteria (e.g. status = 'OPEN').
However, rather than create a DBAdapter using an Operation Type of "Peform an Operation on a Table/Select", I need to use an Operation Type of "Call a Stored Procedure or Function".
I therefore need the procedure to return all the matching rows, rather than a single row.
I have looked at declaring return parameters for the procedure of the following types:
RECORD - is good because it allows me to return the elements of the row with their correct datatypes, but does not meet my needs because it will only support the return of a single row.
VARRAY - good because it can contain many row elements, but not good because it only supports a single row return, and also because all elements of the VARRAY must be of the same data type.
TABLE - good because it can contain many rows, but bad because each row can contain only two elements - the index element and the data element.
I think I could first define a RECORD (to hold a row), and then define a TABLE, with the data element being the RECORD, but I have found JDeveloper very fussy indeed when dealing with 'non-standard' data types in the DBAdapter.
Apologies if I am missing something obvious, but can anyone suggest a way of doing this?
Many thanks in advance.

Hi, I've been able to create process that seems to work. My platform is a but different but I don't think this is important for your question.
Here is the PL/SQL code. Just make Db Adapter for Calling stored procedure and it returns all rows!
Be aware of possible limitations on how manyrows you could return in one select! This can have severe impact on performance.
Succes.

HOW TO EXECUTE A STORE PROCEDURE THAT RETURN MULTIPLE ROWS FROM A QUERY

I NEED TO CREATE AND USE A STORE PROCEDURE THAT IS GOING TO DO A SELECT STATEMENT AN THE RESULT OF THE SELECT STATEMENT IS RETURN IN SOME WAY TO THE REQUESTER.
THIS CALL IS MADE BY AN EXTERNAL LANGUAGE, NOT PL/SQL OR FORMS APPLICATION. USING FOR EXAMPLE ODBC AND VISUAL BASIC. WHAT I NEED TO DO IS ADD A DATA ACCESS LAYER TO MY APPLICATION AND I ALREADY HAVE IT DONE FOR MS SQL SERVER, BUT I NEED THE SAME FUNCTIONALITY ACCESSING AN ORACLE DATABASE.
FLOW:
1. VB CREATE A ODBC CONNECTION TO A ORACLE DATABASE
2. VB EXECUTE A STORE PROCEDURE
3. THE STORE PROCEDURE RETURNS TO THE VB APPLICATION THE RESULT OF THE QUERY THAT IS INSIDE OF THE STORE PROCEDURE.(I.E. THE STORE PROCEDURE IS A BASIC SELECT, NOTHING COMPLEX)
4. VB DISPLAY THE RESULT IN A GRID
FOR SURE I CAN DO THE SELECT DIRECTLY TO ORACLE, BUT FOR PERFORMANCE REASONS AND SCALABILITY, I'LL LIKE IT TO DO IT USING A STORE PROCUDURES
IS THIS POSIBLE?, HOW?
THANKS

Certainly, it's possible. First, define a stored procedure that includes an OUT parameter which is a REF CURSOR. Then, call the stored procedure via ODBC omitting the OUT parameter from the list of parameters. IT will automatically be returned as a result set. Syntax for both is below...
CREATE PROCEDURE foo (inParam in varchar2, resultSet OUT REF CURSOR )
In ODBC:
{call foo( 'someData' )}

Problem with database control returning multiple rows as Array using Oracle

Has anybody using Oracle gotten a Database control that
returns multiple rows to work returning an array?
The only way I can seem to return multiple rows is by returning
a RowSet. Returning an array gives me a NullPointerException
(when called within a pageFlow). When calling a database control
that returns an array from a web service I get a
"java.sql.SQLException: ResultSet has no more data." error.
The samples using the pointbase database seem to work, but when I
converted the CustomerDBClient web service to use Oracle, it starts
failing on calling the database control that returns an array
with: "java.sql.SQLException: ResultSet has no more data."
Has anybody gotten this to work using Oracle?
I'm also having some problem returning an Iterator. It seems
to work when called from a web service, but returns nothing
if called from a page flow.
I'm using Oracle 8.1.7 and WebLogic 8.1.
Eric

Do you need a particular service pack installed to return an array of custom object?
I am getting a ResultSet contained no data error when trying.
Thanks,

There shouldn't be a problem with returning an array of objects out

wrap the array in an Iterator implementation.

I get the same error that Eric reported when trying to return an Array
of objects.
It is really frustrating because I can't use much of the built-in control

that WLW provides. All I did was create a data pool for Oracle and a
datasource.
I modified the sample app in C:\bea81\weblogic81\samples\workshop\SamplesApp\WebApp\callJavaControl

Retruring Multiple rows from a Stored Procedure

The Oracle JDBC documentation shows how to return a cursor pointer through the parameter list of a stored procedure allowing a Java program to use the cursor like a normal result set. I've tried it (using the thin driver) and it works fine - however, I'm having trouble getting this to work running the program under a Weblogic server (using their own JDBC implementation). So, I have two questions:
1) Has anyone had this problem before and solved it ??
2) Are there any other techniques for getting multiple rows back from the database without having to fire "raw" sql at it ?

Hi
You could return not resultset but array, for example:
PACKAGE TEST:
type string_table is table of varchar2(80)
index by binary_integer;
function get_something (
something1 out string_table,
arraylength in number
) return number;
PACKAGE'S BODY:
function get_something (
something1 out string_table,
arraylength in number /** length of the array **/
) return number as
cursor C is
select something1, ...
from test_table;
pos number := 1;
begin
for position in C loop
exit when (pos > arraylength);
something1(pos) := position.something1;
pos := pos + 1;
end loop;
return (pos - 1);
end;
Of course in this example you need to know length of your array
(arraylength parameter), but you can avoid such problem, for
example, by using DBMS_SQL package (or dynamic SQL feature in
the Oracle8i).

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() ;

Retrieve multiple images from database to servlet

Hi there,
I try to retrieve more than one images from database to Servlet/JSP . However, I get only one images in the result set. Here is my code. Please Help .
How do I display more than one images ( multiple rows ) from database to Servlet ?.
When I retrieve, I got 3 rows of binary data, but I don't know how to display it on the Servlet/JSP pages.
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.lang.*;

String PID = req.getParameter("PID"); //passing parameters from Servlet
try {
String SQLcmd = "{call RET_PHOTO_BY_PID(?)}";
NGSstmt = NGScon.prepareCall( SQLcmd );
//execute the query
synchronized (NGSIDBstmt)
NGSstmt.setString(1, PID); //passing parameter to store procedure
rs = NGSstmt.executeQuery();
byte[] stuff = new byte[1024];
int bytesRead = 0;
res.setContentType("image/gif");
InputStream is = null;
// Get the first row
while( rs.next() ) {
is = rs.getBinaryStream("PHOTO");
res.setContentLength(is.available());
for (int i=0;; i++) {
bytesRead = is.read(stuff);
os.write(stuff);
if ( bytesRead == -1 ) break;
rs.close();
os.flush();
os.close(); //close outputstream
} catch ( SQLException sqle) {
os.println("Error in SQL2Exception" + sqle.getMessage());

When I retrieve, I got 3 rows of binary data, but I don't know how to display it on the Servlet/JSP pages.I will pick this bit of your post, because you seemed to have several partly-overlapping questions.
You are going about this wrong. You need to decide what your HTML will look like before you start writing servlet code. In this case you want to have something like a table, with an image in each row, right? Now what does the HTML for that look like? It's a <table> element, and so on, but what about the images? Well this is HTML, so it can't contain the binary images. It has to contains links to the images, and the browser will download the image from each of those links and put all of the downloads together into the page it displays.
That means you can't do it all with one servlet. You need a main servlet that generates the HTML, with the <table> element and the links to the images. Probably you need some DB calls here to find out how many images you're going to have, but you don't need to get them in this servlet. You just need to generate a link for each of them.
Then you need a second servlet that gets an image. It's going to get a single row from the DB and return the binary image you read from that row. Make sure to use "image/jpg" or whatever's appropriate instead of "text/html" in your response's content type here.
I will leave you to carry on from here. First step is to design the HTML that your main servlet will produce; remember that the links it generates need to carry enough information for the second servlet to be able to find the right image in the DB.

FWD: Re: Retrieving multiple rows from a database into morethan

There are two ways to do this that I cn think of right off the bat.
One is to create a class of objects that can receive the entire row, and
give it methods that will return each of the individual objects that you are
looking for when called. If you use INTO :ARRAY, you get the advantage of
being able to pass the array anywhere in your system for the 'split up'
processing.
Two is to do basically the same thing, but instead doing the 'split up'
during a for loop. This will appear to slow down your query, however, as
extra processing will be occuring in terms of memory allocation and copying.
I'm sure there other approaches. This was simply what came to mind at
midnight, after a long day :-).
At 01:33 AM 6/4/96 +0000, you wrote:

The FOR clause only allows one object to be specified.
The INTO :ARRAY clause also seems to only allow one object to be specified.

Procedure from PowerBuilder returning multiple rows

In want to call a procedure from PowerBuilder which return multiple rows. I would like to know how to write the procedure and also how to call it. I tried using REFCURSOR , but i heard that Powerbuilder doesnot support REFCURSOR . Please help
Thanks in advance

This is not a PL/SQL qustion, but a Powerbuilder question.
Just what SQL constructs does Powerbuilder supports? And if there is no support for ref cursors, then the choice of using a client language that lacks basic core SQL support is questionable.

Let's say for example user have to the use the form to enter all 10 items or few like 5 on their stock form into 4 different textbox field each lines of your form, however these items go into a "Stock_table" under Single insert transaction query when submit button is pressed.
Please anyone help me out, on how to get this concept started.

Hello,
I have a way to do this, but it would take some hand coding on your part. If you feel comfortable hand writing php code and doing manual database calls, specificaly database INSERT calls you should be fine.
Create a custom form using the ADDT Custom Form Wizard that has all the rows and fields you need. This may take a bit if you are adding the ability for up to 20 rows, as per your diagram of the form area. The nice thing about using ADDT to create the form is that you can setup the form validation at the same time. Leave the last step in the Custom Form Wizard blank. You can add a custom database call here, but I would leave it blank.
Next, under ADDT's Forms Server Behaviors, select Custom Trigger. At the Basic tab, you enter your custom php code that will be executed. Here you are going to want to put your code that will check if a value has been entered in the form and then do a database INSERT operation on the Stock_table with that row. The advanced tab lets you set the order of operations and the name of the Custom Trigger. By default, it is set to AFTER. This means that the Custom Trigger will get executed AFTER the form data is processed by the Custom Form Transaction.
I usually just enter TEST into the "Basic" tab of the Custom Trigger. Then set my order of operations in the "Advanced" tab and close the Custom Trigger. Then I go to the code view for that page in Dreamweaver and find the Custom Trigger function and edit the code manually. It's much easier this way because the Custom Trigger wizard does not show you formatting on the code, and you don't have to keep opening the Wizard to edit and test your code.
Your going to have to have the Custom Trigger fuction do a test on the submitted form data. If data is present, then INSERT into database. Here's a basic example of what you need to do:
In your code view, the Custom Trigger will look something like this:
function Trigger_Custom(&$tNG) {
if($tNG->getColumnValue("Item_1")) {
$item1 = $tNG->getColumnValue("Item_1");
$textbox1_1 = $tNG->getColumnValue("Textbox_1");
$textbox1_2 = $tNG->getColumnValue("Textbox_2");
$textbox1_3 = $tNG->getColumnValue("Textbox_3");
$date1 = $tNG->getColumnValue("Textbox_3");
$queryAdd = "INSERT INTO Stock_table
(item, Qty_In, Qty_Out, Balance, Date) VALUES($item1, $textbox1_1, $textbox1_2, $textbox1_3, $date1)"
$result = mysql_query($queryAdd) or die(mysql_error());
This code checks to see if the form input field named Item_1 is set. If so, then get the rest of the values for the first item and insert them into the database. You would need to do this for each row in your form. So the if you let the customer add 20 rows, you would need to check 20 times to see if the data is there or write the code so that it stops once it encounters an empty Item field. To exit a Custom Trigger, you can return NULL; and it will jump out of the function. You can also throw custom error message out of triggers, but this post is already way to long to get into that.
$tNG->getColumnValue("Item_1") is used to retrieve the value that was set by the form input field named Item_1. This field is named by the Custom Form Wizard when you create your form. You can see what all the input filed names are by looking in the code view for something like:
// Add columns
$customTransaction->addColumn("Item_1", "STRING_TYPE", "POST", "Item_1");
There will be one for each field you created with the Custom Form Wizard.
Unfortunately, I don't have an easy way to do what you need. Maybe there is a way, but since none of the experts have responded, I thought I would point you in a direction. You should read all you can about Custom Triggers in the ADDT documentation/help pdf to give you more detailed information about how Custom Triggers work.
Hope this helps.

The simplest way for plsql procedure to return multiple rows

Hi,
What is the simplest way for plsql procedure to return multiple rows (records). There are many combination of ways to do it but I am looking for a solution that is appropriate for plsql beginners. Many solutions use cursors, cursor variables, collections and more that kind of things that are complex on the face of it. Is it somehow possible to achieve the same with less effort?
Sample query would be: SELECT * FROM EMPLOYEES;
I want to use returned rows in APEX to compose APEX SQL(in that context plsql) report.
It is enough to use just SELECT * FROM EMPLOYEES query in APEX but I want to use plsql procedure for that.
Thank you!

Hi,
It depends :-).
With +...that is appropriate for plsql beginners...+ in mind... it still depends!
The list of techniques (ref cursors, cursor variables, collections, arrays, using explict SQL) you have referenced in your post can be made to work. but...
+Is it somehow possible to achieve the same with less effort?+ Less effort : That needs to be defined (measured). Especially in the context of pl/sql beginners (who is a beginner?) .
What is the level of "programming experience" ?
What is the level of understanding of "Relational Result set" as processible in Oracle?
If you are looking for
Process_the_set_of rows_in APEX () kind of capabilitywhich "abstracts/hides" relation database from developers when working on relation database, it may not be the best approach (at least strategically). Because I believe it already is abstracted enough.
I find REF CUROSOR most effective for such use, when the "begginer" has basic understanding of processing SQL result set .
So in a nut shell, the techniques (that you already are familiar with) are the tools available. I am not aware of any alternative tools (in pure Oracle) that will simplify / hide basics from develpers.
