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' )}

  • Stored procedure that returns multiple tables

    Hello everyone,
    I was wondering if there's a way to write a stored procedure that returns multiple result set as in sql server. for example, in sql server, you can write 2 select statements and when loading them in c#, u can get two data tables.
    I am not sure having a single ref cursor for each select is the only solution. I might need to return a variable number of tables per procedure call (based on a certain criteria).
    Any ideas?
    thanks for your time

    Sure. Ref cursor is the only easier answer for your problem.

  • 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.

  • 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.
    If this answers your question please mark it accordingly. If this post is helpful, please vote as helpful by clicking the upward arrow mark next to my reply.

  • (Resolved) How to execute 2 store procedures in 1 transaction?

    public void method1(){
    Session session = getSessionFactory().acquireSession();
    StoredProcedureCall spc1 = new StoredProcedureCall();
    spc1.setProcedureName("PKG.SP1");
    spc1.addNamedArgumentValue("param", "aaa");

    spc2.addNamedArgumentValue("param", "bbb");
    session.executeNonSelectingCall(spc2);
    The above method is defined in SessionFacadeBean (just like the EJB in SRDemo),
    I want the above 2 procedures executed in 1 transaction. If spc2 failed, the spc1 should not be committed. How can I do this?

    I have changed code as follows:
    public void method1(){
    DatabaseSession session = getSessionFactory().getSharedSession();
    session.beginTransaction();
    try{
    StoredProcedureCall spc1 = new StoredProcedureCall();
    spc1.setProcedureName("PKG.SP1");
    spc1.addNamedArgumentValue("param", "aaa");
    session.executeNonSelectingCall(spc1);
    StoredProcedureCall spc2 = new StoredProcedureCall();
    spc2.setProcedureName("PKG.SP2");
    spc2.addNamedArgumentValue("param", "bbb");
    session.executeNonSelectingCall(spc2);
    } catch (Exception e) {
    session.rollbackTransaction();
    } finally {
    session.release();
    It seems that the "session.rollbackTransaction();" will be executed if spc2 fails.

  • 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.

So for Deptno 10 you'll only get the row with SUB_DEPTNO = 103. But if for that DEPTNO= 20 you'll get the rows for both SUB_DEPTNO = 201 and 202.
    So the result should look like
    DEPTNO   SUB_DEPTNO
    10          103
    20          201
    20          202
    30          301.
    Basically I just want rows from each department that have code_ids = 111 not to show up if there are code_ids = 112.
    What is the query to do this?

  • How to extract multiple rows from a query and how to populate it in form.

    hi all,
    i want to populate multiple rows fetched from a cursor into form.
    i write this procedur.
    PROCEDURE populate_q (v_t_no IN number) IS
    cursor ext_q is
    select test_question.no, q_no, text, ans1
    from test_question , question
    where test_question.no = v_t_no;
    BEGIN
    for ext_rec in ext_q loop

         :take_detail.question := ext_rec.text;
         EXIT WHEN ext_q%notfound;
         end loop;

    and call this WHEN-NEW-BLOCK-INSTANCE trigger.
    this don't return all the rows only the lost one is populated
    and shown in form.

    Hi,
    look for the next_record built-in. Your cusror only addresses the current row, but you want to create new rows as you go

  • Need help with a SQL qurey that returns multiple rows for one record?

    I have the following query where I use a CASE WHEN clause to determine the date of a shift that begins with "FRLO" on day1 - day14 of the pay period. It works great if a schedule record contains one day that begins "FRLO", but if more than one day is "FRLO" then it only returns the first day it finds and not the others. Is there some way to get the query to return a ron for every day 1 - 14 that begins "FRLO"? System if Oracle 11G
    Order of the results is not important as this is part of a larger query that orders the results.
    Thanks in advance for any help,

    Do you have the opportunity to change the data model to have one day per row ? It would make this easier to get this result without the need for a 14-way CASE or UNION.
    If not...
    The case statement will return as soon as it matches one of the conditions. Since you want a match when any column in the row starts with FRLO you can use a UNION ALL treating each column as a separate result. There may be more efficient ways to do this, but here is one way:

  • How to execute procedure returning data rows from sql plus

    Hi,
    I want to execute a stored procedure that returns data rows from sql plus. please let me know the syntax for the same.
    Thanks,
    YG

    Even if i get the result set into the cursor, do i have to do normal fetch into all the coumn variables within a loop
    But suppose no of columns in my result set varies depending on a parameter to the stored procedure.
    Is there any straightforward way to retrieve all the data irrespective of no of columns in the result set.There is no such thing as a "+result set+". Oracle does not create a temporary data set in memory that contains the results of your query. What would happen if this result set is a million rows and is too large to fit into memory? Or there are a 100 clients each with a 100,000 row result set?
    This is not scalable. You will be severely limited in the number and sizes of these "+result sets+" that can be created in server memory.
    A cursor is in fact a "program" that is created by compiling the SQL source code that you provide. This source code is parsed and compiled into what Oracle calls an execution plan. This is nothing but a series of instructions that the cursor will execute in order to return the rows required.
    Thus the result set is actually the output from a cursor (a program). Likewise, bind variables are the input parameters to this program.
    All SQLs are parsed and compiled as cursors and stored in the SQL Shared Pool. Oracle gives you handle in return to use to address this cursor - bind values to it, execute it, describe the output structure returned by the cursor, and fetch the output from the cursor.
    On the client side, this handle is used in different ways. In PL/SQL alone, this cursor handle can be used as an implicit cursor (you do not even see or use the cursor handle in your PL/SQL code). Or you can use a PL/SQL cursor variable. Or a DBMS_SQL cursor variable. Or a reference cursor variable.
    Why so many different client structures for the very same SQL cursor handle returned by Oracle? Because to allow you, the programmer, all kinds of different features and flexibility.
    The ref cursor feature is the ability to pass this cursor handle around, not only between PL/SQL code, but also from PL/SQL to the actual client process (Java. VB, SQL*Plus, TOAD, etc).
    The primary thing to remember - irrespective of what the client calls this (e.g. ref cursor, SQL statement handle, etc), this all refers to the same SQL cursor in the Shared Pool. And that this SQL cursor is a program that outputs data, and not a result set in itself.

Maybe you are looking for
