Calling a storeed proc from jap

How do we call a stored procedure from a jsp?

And to do the call (either from the JSP, which I also don't recommend, or from somewhere else) use CallableStatement. Read the API documentation for more information on how to use it.

S'one tell me how to call Oracle Stored Proc from Java

Hi,
I have a problem in calling the Stored proc using callable statement.It looks like we are doing the same thing or no..
Pl..let me know if you can correct me..Am enclosing the stored proc and java Code...
CREATE OR REPLACE PROCEDURE StoreFTPAddress (FTP in FTPTYPE) is
BEGIN
INSERT INTO DES.FTPSERVICE(

Syntactically it looks fine. Only thing is u r calling the proc with wrong name. Your procedure takes only one parameter and i.e
IN type. I think u need to correct ur preparecall statement.

odi version we have is ODI_11.1.1.6.0, it is not migrated and 'Always Execute' option is checked already.
tried using variables in capital format but did not worked,
begin
schema_name.proc_name(#LV_TABLE_NAME,#LV_SCHEMA_NAME,#LV_START_DATE,#LV_END_DATE);

odi is giving error if it finds any bug in stored proc but after fixing its completing successfully without errors in operator but i am not able to see the result.
Please advise.

Trying to call a stored proc from a form ?

Hi im trying to call a stored procedure that create a web page
any where from within a form. (the SP It uses the htp package).
It does not seem to work.
lets say in the PL/SQL block before the footer i pu
<schema>.my_procedure;
i get a not decleared <schema>.my_procedure error.
Could someone help !
Also is there a way to call stored proc directly from the url
I tried httP://hostname/pls/portal30/<schema>.my_procedure
unsuccessful.
thanks

For it to work, you should grant EXECUTE on your Procedure to
PUBLIC.
Have you done that?
If yes then there is a problem.

Is there a way to call a stored proc from the web in Oracle 10g?

I've found an article about Native Oracle XML DB Web Services in 11g, but it appears to be a new feature. Is there any way of accomplishing something similar in 10g? I would like to be able to process XML documents that contain the name and parameters of the stored proc/function to execute.
Link to 11g article:
http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm

I agree with you. I was looking into mod_plsql, but it turns out that their development standards include not using Oracle HTTP server. The whole reason why they want to be able to execute a stored proc based on what is specified in an XML doc is that they want to avoid having to change their middle-tier configurations anytime a new stored proc or a change in stored proc parameters is made. I'm not familiar with what all is involved with .NET and the middle-tier, but supposedly this way, they can specify any stored procedure name and its parameters in an XML file. The XML is then suppose to be passed on to an Oracle stored procedure which will parse the XML and dynamically execute the stored procedure that was specified in the XML.
Here is an example of the XML:
'<Root>
<PackageName>TEST_PKG</PackageName>
<ProcedureName>TEST_PROC</ProcedureName>
    <Parameters>
    <Parameter>
        <Name>EmpID</Name>
        <Value>12345</Value>
    </Parameter>
    <Parameter>
        <Name>Org</Name>
        <Value>ABC</Value>
    </Parameter>
    </Parameters>
</Root>I basically need to parse out the pkg/proc names:
SELECT t.COLUMN_VALUE.extract('//PackageName/text()').getstringval() PkgName,
         t.COLUMN_VALUE.extract('//ProcedureName/text()').getstringval() ProcName
     INTO v_pkg_name, v_proc_name
     FROM TABLE(xmlsequence(XMLTYPE(v_XML_input) .extract('/Root'))) t;...and then execute the procedure:
    EXECUTE IMMEDIATE 'BEGIN '||v_pkg_name||'.'||v_proc_name||'(:a, :b, :c); END;'
      using in v_in_param1, v_in_param2, out v_XML_output;The problem is that this approach is very complicated since there can be any number of IN/OUT parameters and of various datatypes. I would have to create all kinds of possible bind variables!

Call stored proc from inside sp

I am trying to call a stored proc from inside a stored proc and the stored proc needs to return a ref_cursor. I am trying to loop over the returned ref_cursor, but my problem is that when I compile the sp it says the ref_cursor is not a procedure or is undefined. Can anyone please tell me why I am getting this error? Refer to the code below!
create or replace
PROCEDURE TCS_GetPartReferenceData
contracts IN VARCHAR2
, showInWork IN INTEGER
, userClock IN VARCHAR2
, intMaxResults IN INTEGER
, ret_cursor OUT SYS_REFCURSOR
) AS
p_cursor SYS_REFCURSOR;
BEGIN
TCS_GETDRNSFORCONTRACTS(contracts
, showinwork
, userClock
, intmaxresults
, p_cursor);
for r in p_cursor loop
dbms_output.put_line(r.puid);
end loop;
END TCS_GetPartReferenceData;

Probably you want sth. like
CREATE OR REPLACE PROCEDURE tcs_getpartreferencedata (contracts       IN     VARCHAR2,
                                    showinwork      IN     INTEGER,
                                    userclock       IN     VARCHAR2,
                                    intmaxresults   IN     INTEGER,
                                    ret_cursor         OUT sys_refcursor)
AS
BEGIN
   tcs_getdrnsforcontracts (contracts,
                            showinwork,
                            userclock,
                            intmaxresults,
                            ret_cursor);
END tcs_getpartreferencedata;
var cur refcursor
exec tcs_getpartreferencedata(contracts_value,showinwork_value,userclock_value,intmaxresults_value, :cur)
print curfill in appropriate values for the parameters _value ....

Calling a COBOL stored proc from Java Servlet

I am trying to call a COBOL stored proc from a Java Servlet. The stored proc is stored on a DB2 database. I need to send 6 inputs to the COBOL stored proc and the output will be the return code of the stored proc. I'm not sure if I'm going about this the right way. This is how my code looks...
public int callStoredProc(CallableStatement cstmt,
Connection con,
String sYear,
String sReportNbr,
String sSystemCode,
String sUserId,
String sModuleNbr,
String sFormId){
int iParm1 = 0;
try{
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
catch(ClassNotFoundException ex){
System.out.println("Failed to locate database driver: "
+ ex.toString());
return iParm1;
try{
cstmt = con.prepareCall("{? = CALL MKTPZ90C
cstmt.registerOutParameter(1, Types.INTEGER);
cstmt.setString(2, sYear);
cstmt.setString(3, sReportNbr);
cstmt.setString(4, sSystemCode);
cstmt.setString(5, sUserId);
cstmt.setString(6, sModuleNbr);
cstmt.setString(7, sFormId);
cstmt.execute();
iParm1 = cstmt.getInt(1);
CloseSQLStatement(cstmt);
catch(SQLException ex) {
CloseSQLStatement(cstmt);
System.out.println("SQL exception occurred:" +
ex.toString());
return iParm1;
return iParm1;
Could someone tell me if this is the right way to go about doing this?
Thanks!!!!!!

I didn't see the code where you create the database connection (variable "con"). However, the answer to your question "Is this the right way...", for me, is "Anything that works is the right way." So try it. That's a first approximation, but once you have something that works you can start on improving it, if that becomes necessary.

Can we call a Java Stored Proc from a PL/SQL stored Proc?

Hello!
Do you know how to call a Java Stored Proc from a PL/SQL stored Proc? is it possible? Could you give me an exemple?
If yes, in that java stored proc, can we do a call to an EJB running in a remote iAS ?
Thank you!

For the java stored proc called from pl/sql, the example above that uses dynamic sql should word :
CREATE OR REPLACE PACKAGE MyPackage AS
TYPE Ref_Cursor_t IS REF CURSOR;
FUNCTION get_good_ids RETURN VARCHAR2 ;
FUNCTION get_plsql_table_A RETURN Ref_Cursor_t;
END MyPackage;
CREATE OR REPLACE PACKAGE BODY MyPackage AS
FUNCTION get_good_ids RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'MyServer.getGoodIds() return java.lang.String';
FUNCTION get_plsql_table_A RETURN Ref_Cursor_t
IS table_cursor Ref_Cursor_t;
good_ids VARCHAR2(100);
BEGIN
good_ids := get_good_ids();
OPEN table_cursor FOR 'SELECT id, name FROM TableA WHERE id IN ( ' | | good_ids | | ')';
RETURN table_cursor;
END;
END MyPackage;
public class MyServer{
public static String getGoodIds() throws SQLException {
return "1, 3, 6 ";

Can i call stored proc from VOImpl, not from AM?

Hi,
i know how to invoke proc from bb defined in AM...
in VOImpl i have a method getSelectedRows()
which gets me rows selected in table by user.
how can i invoke stored proc from there?
Edited by: grodno on Jan 31, 2013 3:35 AM

Hi,
its exactly the same code. The only missing link you have is the access to the transaction. In a Viewimpl file just call this.getApplicationModule() to get access to an application module.
The method can also be exposed on a client interface (same as for AM)

Calling Oracle Stored Procedure from BC4J JSP App

I am on an extremely tight deadline and am trying to get my JSP application to use an Oracle Stored Procedure. I need to take some input from the user and send these values as parameters. Has anyone worked with Stored Procedures in JDev3.1? Please reply with some sample code if possible.
Thanks.

Hi,
Someone posted a similar request the other day. Here is my response to them:
Basically, you need to create a custom method from your JSP's ViewObject, which calls the stored procedure. You can then call the ViewObject's custom method from the JSP client.
Here is how I have done it:
1. Choose the ViewObject that your JSP is based on and choose 'Edit' from the context menu.
2. On the Java tab of the ViewObject wizard, choose Generate Java File checkbox for the View Object Class and click the Finish button. A file is created under the ViewObject node in the Navigator named 'viewobjectImpl.java'.
3. Open the viewobjectImpl.java file in the code editor and create a method to call your stored procedure (see sample code below).
4. Compile the VOImpl.java file.
5. Choose the view object again, and choose Edit again from the context menu.
6. On the Client Methods tab, you should now see your method appear in the Available field. Select it and shuttle it to the Selected field.
7. Click Finish to leave the VO wizard, and rebuild your Business Components project.
8. In your JSP, call the custom method (see sample code below).
sample code for custom method calling a stored procedure from VOImpl.java file:
public int getTotalHits(String mon, String year) {
CallableStatement stmt = null;
int total;
// the call to the PL/SQL stored proc
String totalhits = "{? = call walkthru.total_hits(?,?)}";
// use the AM conxn 2 call storedproc
stmt = getDBTransaction().createCallableStatement(totalhits, 1);
try
// Bind the Statement Parameters and //Execute this Statement
stmt.registerOutParameter(1,Types.INTEGER);
stmt.setString(2,mon); stmt.setString(3,year);
stmt.execute();
total = stmt.getInt(1);
catch (Exception ex)
throw new oracle.jbo.JboException(ex);
finally
try
stmt.close();
catch (Exception nex)
return total;
sample render code for calling custom method from JSP custom bean:
public void render() {
int totalhits;
try
Row[] rows;
// Retrieve all records by default, the qView variable is defined in the base class
qView.setRangeSize(-1);
qView.first();
rows = qView.getAllRowsInRange();
// instantiate a view object for our exported method
// and call the stored procedure to get the total
ViewObject vo = qView.getViewObject();
wtQueryView theView = (wtQueryView) vo;
totalhits = theView.getTotalHits(session.getValue("m").toString(),session.getValue("y").toString());
out.println(totalhits);
} catch(Exception ex)
throw new RuntimeException(ex.getMessage());
}

Can i call a stored procedure from OracleDashboardPrompt?

Hi,
Can i call a stored procedure from OracleDashboardPrompt once i click the Go button in OBIEE?The input parameters to the procedure are the one that i have given in DashboardPrompt.and based on the result of the procedure(either 0 or 1),i have to display reports.Can anyone help me.
Thanks in Advance...

Please find below the possible approach to the scenario:
1.Create a prompt for the column which you need as input to store proc and create a presentation variable for that .
2.Create a dummy report with 1 column which will have the above created presentation variable as filter(We can design this reports in such a way like the first column will get filtered based on the presentation variable)
3.Create a second column and in the column definition we can add a code like
evaluate('StoreProc(%1)','@{firstcolumn}')
4.We can hide the first column in the report and only show the output of store proc to the end user
Hope this helps :)

How to call a stored procedure from WorkShop

Hello Everyone .. I'm quite new with WebLogic 8.1 & WorkShop, so please bare with
me .. Today I'm simply trying to find out how to call a stored procedure from
within workshop, using any of the DB Controls .. I see workshop provides a way
create a Java Control, Rowset Control, but it wont easily allow for a stored procedured
to be entered in place of the inline query .. Perhaps I've over looked it. Any
advise on the best way to tackle this task will be appreciated.

Calling a stored procedure from within a ViewObject

Is it possible to make stored procedure call from within a BC4J ViewObject? Basically something like this:
select * from table(f1(3)); where f1 is a table function. Using Oracle's pipelined table functions?
If not, is it possible to call a stored procedure from Java and have the returned results be put back into a BC4J RowSet.
In addition, is there a way to create a JDBC Resultset from a BC4J RowSet?
We need to be able to dynamically create our SQL statements (the entire SQL, not just the where clause) but are required to have these sql statements generated/executed from within a pl/sql stored procedure in the database.

Is it possible to make stored procedure call from within a BC4J ViewObject? Basically something like this:
select * from table(f1(3)); where f1 is a table function. Using Oracle's pipelined table functions?
Yes. Using our expert-mode query feature this is possible.
is it possible to call a stored procedure from Java and have the returned results be put back into a BC4J RowSet.
Yes. See this article about basing a view object on a REF CURSOR:
http://radio.weblogs.com/0118231/2003/03/03.html
In addition, is there a way to create a JDBC Resultset from a BC4J RowSet?
No. Not directly. What's the business requirement here so I can understand better?
We need to be able to dynamically create our SQL statements (the entire SQL, not just the where clause) but are required to have these sql statements generated/executed from within a pl/sql stored procedure in the database.
REF CURSOR would work fine, or if it's just the statement that needs to be generated dynamically, you could fetch the text of the SQL statement from the stored procedure, then use createViewObjectFromQueryStmt(). Although this has runtime overhead involved with describing the query.
The REF CURSOR based approach is probably best for this.

Calling a stored procedure from a url

I am needing to call a stored procedure from a url string (or
anchor) understand that from training to be as follows:
http://host:port/pls/dad/package.procedure?query_string
With that in mind, I am getting an error as follows:
Not Found
The requested URL /pls/portal30/at_hrfm.checkshow.showcheck was
not found on this server.
Here is a sample of my url
http://servername:port/pls/portal30/at_hrfm.checkshow.showcheck
I can see servername:port/pls/portal30, it is just the
procedure I am having a problem with.
Here is a sample of my source code that is created under the
at_hrfm schema (I also tried under portal30 schema).
package body checkshow as
procedure showcheck as
begin
htp.htmlOpen;
htp.headOpen;
htp.title('My Check');
htp.comment ('This should be your Check');
htp.bodyOpen;
htp.header (1,'Check');
htp.print ('checkdate');
htp.bodyClose;
htp.headClose;
htp.htmlClose;
end;
end;

I think I figured this out. I don't think the grant to ANONYMOUS is going to work with production XE and the online documentation is in need of an update. It appears that production XE has been locked down and you will need to specify the name of each stored procedure you wish to allow to be executed by adding it to the WWV_FLOW_EPG_INCLUDE_MOD_LOCAL function. This is spelled out in more technical detail here: http://download.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/adm_wrkspc.htm#BEJCGJFJ
Another alternative that would work involves creating a separate DAD. Using the DAD approach with my schema made all of my stored procedures callable from a web browser, so I rejected this approach. To make this usable (secure) I would have needed to create and maintain a separate database user for the DAD and then only granted it execute for the stored procedures I wanted to be callable from a URL.
Finally I read about using an on-demand procedure and having it invoke the desired stored procedure. While I didn't try this out, it sounds like another good approach because it maintains session security. If it can be used to return an image I do not know.
