Calling Oracle Stored Procedure from Weblogic.

Hi All,
I am using Oracle 11g R2 and weblogic 10.3.5.0
Do you know if it is possible to call a stored procedure from Weblogic.
Basically, what I would like to do is to call the following procedure : EXEC DBMS_SESSION.SET_IDENTIFIER('provider_a') when my application connects to my database, "provider_a" being the user used to connect to the oracle schema.
Thanks.

Up !
Thanks.

Problem in calling Oracle stored procedure from Java.

I am trying to invoke the Oracle stored procedure from Java. The procedure does not take any parameters and does not return anything. If I call it from SQL prompt it is working perfectly. I am calling it in my program as follows.
callable_stmt=con.prepareCall("{call pkg_name.proc_name()}");
callable_stmt.execute();
The problem is the control-of-flow is getting strucked in the second line I wrote. It is not giving any error also.
Please clarify me what's wrong with my code?

And how long does the stored procedure take to run from your client machine when running it via sqlplus?

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());
}

Calling Oracle stored procedure from xMII Query Templates.

Hi All,
We have a requirement to call a Oracle stored procedure from xMII, the SP expects some inputs and then it returns multiple rows.
I tried different approches with no results, I remember some posts on the same topic but I could not get in search results.
Looking for some help in this regards
Rupesh.

Hi Rupesh Bajaj,
In oracle stored procedure we have to use Packages..if you used packages the u have to assign to some variable.
To calling Stored procedure in Query Template is CALL Testing('[Param.1]','[Param.2]',,:X)
In above line Testing is Stored procedure name and Param.1 is parameters and X is Package.
Thanks

Calling Oracle stored procedure from java

The following query calls a stored procedure TRANSLATE_ZONEPATH_ID defined in a package MT by the user MTDBA. currentZone is a member variable of the class, and currently has value 1
This query works just fine when I run it from SQLPlus* connected as MTDBA.
But from java, the following piece throws exception saying "invalid column name"
String query = "SELECT MTDBA.MT.TRANSLATE_ZONEPATH_ID('"+currentZone+"') "
+ "FROM DUAL ";
try
Statement stmt = conn.createStatement();
ResultSet rst = stmt.executeQuery(query);
if (rst.next())
fullName = rst.getString(1);
stmt.close();
Anyone got any clue ?

I always use CallableStatement to execute a stored procedure or function in a database (Oracle).
try this:
<code>
CallableStatement cs = dbConnection.prepareCall("{ ? =
MTDBA.MT.TRANSLATE_ZONEPATH_ID(?)}");
cs.setString(1, currentZone);
cs.registerOutParameter(1, Types.VARCHAR);
cs.executeUpdate();
fullname = cs.getString(1);
cs.close();
</code>
There is also a jdbc forum, where your should post this kind of problem :-)
Hope this help's

Error Calling Oracle Stored Procedure From Within Report

Hi,
I have a report that calls an oracle stored procedure which returns a ref cursor. The report is working ok in our development environment when called from our development website through .NET.
When the report is moved and accessed from our UAT website we get the following error :-
Failed to open a rowset. Details: ADO Error Code: 0x Source: Microsoft OLE DB Provider for Oracle Description: One or more errors occurred during processing of command. Failed to open a rowset. Details: ADO Error Code: 0x Source: Microsoft OLE DB Provider for Oracle Description: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'RHS_GET_CAND_SECTION_REFS' ORA-06550: line 1, column 7: PL/SQL: Statement ignored Native Error: Failed to open a rowset. Error in File C:\WINDOWS\TEMP\temp_d663a952-bef6-4bf7-bf1a-5e288afdb612 {9B6DFB38-A436-4940-9D80-B4C23DFFFF19}.rpt: Failed to open a rowset.
If we open the report manually we are prompted to enter database connection info. If we enter the UAT connection details the report runs ok. If we save the report and try to open it from UAT website through .NET it now opens ok.
If we then move that same report back to the development environment and open from our development website it fails with the same error above.
Both connections are using Microsoft OLE DB drivers and the Oracle databases are the same version (10.2.0.1.0).
Is the connection information being stored in actual report and somehow being used when the report is opened through .NET?
Any help appreciated

Paul

Problem Calling Oracle Stored Procedure From JAVA

Hello all. I've been banging my head against this all day:
Here's the procedure I'm calling:
GetIDsByLatLonRadius(inLatitude IN NUMBER,
inLongitude IN NUMBER,
inRadius IN NUMBER,
inTableName IN VARCHAR2,
inIDColName IN VARCHAR2,
inLatColName IN VARCHAR2,
inLonColName IN VARCHAR2,
LocationIDs OUT HomesCom_Types.GenericCursorType,
ErrorNo OUT VARCHAR2);
And here's the JAVA code:
public Hashtable GetInRadius(Hashtable inStruct)
ResultSet locationIDs = null;
Hashtable outputHash = new Hashtable();
float latitude = (float) 30.429;
float longitude = (float) -84.2585;
float radius = (float) 10;
try {
CallableStatement proc = con.prepareCall("{ call GEOCODING.getidsbylatlonradius(?,?,?,?,?,?,?,?,?) }");
proc.setFloat(1,latitude);
proc.setFloat(2,longitude);
proc.setFloat(3,radius);
proc.setString(4,"demographics_school");
proc.setString(5,"onboard_id");
proc.setString(6,"geocoding_latitude");
proc.setString(7,"geocoding_longitude");
proc.registerOutParameter(8,OracleTypes.CURSOR);
proc.registerOutParameter(9,OracleTypes.VARCHAR);
proc.execute();
locationIDs = (ResultSet) proc.getObject(1);
if (locationIDs != null)
outputHash.put("query",locationIDs);
else
outputHash.put("query","LOCATION ID WAS NULL");
catch(SQLException sqlException) {
System.out.println(
"The following error occured in reading " +
"from the table: "
+ sqlException);
outputHash.put("error",sqlException.getMessage());
return outputHash;
This catches and the sqlException I get is: Unhandled sql type
I'm not a java expert and I'm completely stuck at this point, so I figured a few more eyes on it might help.
Thanks in advance,
Danny

Danny,
Don't print merely the error message, print the whole stack trace.
Then post it here.
What java version are you using?
What JDBC driver and version are you using?
What Oracle database version are you using?
Is the code from a Java ServerPages (JSP) or from a Java Stored Procedure (JSP)?
I guess "HomesCom_Types" is one of your PL/SQL packages or routines, right?
If so, then you can't use it in JDBC, you must define a database type using the command:
create or replace type ...But in later versions of the Oracle database, the REF CURSOR type is built-in.
Check the Oracle documentation for more details.
Good Luck,
Avi.

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:

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.

Calling packaged stored procedure from Java

Hi All,
I'm trying to call a stored procedure from Java but I'm having
problems with registrating the output parameter. I'm getting
the error: Conflicting parameters.: sqltype=2003
This is the stored procedure which is located in a package in
the Oracle database:
package Pack_GetAgencyInformation as
Type InfoType is record ( agen_code varchar(3), agen_designation
varchar(30), agen_adresse varchar(60), agen_tel varchar(12) );
function GetAgencyInformation( P_AGENCE VARCHAR )
return Pack_GetAgencyInformation.InfoType
end Pack_GetAgencyInformation;
This is the Java source from where I'm calling the procedure:
//DriverManager.registerDriver (new
oracle.jdbc.driver.OracleDriver());
     Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@164.48.69.125:1521:ventes", "system", "*****
// @machineName:port:SID,
userid, password
CallableStatement cs = conn.prepareCall("{ ? = call
Pack_GetAgencyInformation.GetAgencyInformation( ? )}");
     try {
          cs.registerOutParameter( 1,
oracle.jdbc.driver.OracleTypes.ARRAY);
     } catch (SQLException e) {
          e.printStackTrace();
     cs.setString(2, "001" );
     //ResultSet rset = cs.executeQuery();
The stacktrace:
java.sql.SQLException: Parametertypen conflicteren.:
sqlType=2003
at oracle.jdbc.dbaccess.DBError.throwSqlException
(DBError.java:168)
at oracle.jdbc.dbaccess.DBError.throwSqlException

(OracleCallableStatement.java:220)
at
oracle.jdbc.driver.OracleCallableStatement.registerOutParameter
(OracleCallableStatement.java:350)
at dbAccess.main(dbAccess.java:25)
I think it has to do with the type InfoType which is created in
the Stored Procedure. I'm absolute no Oracle expert and I
prefer not to make changes to the Oracle database. So any
solution in Java is welcome!
BR, H.Rietman

I managed to get it to work only by changing the stored
procedure. I have changed the return type record to a Ref
Cursor type (had to change alot of code for this). It seams
that Oracle JDBC drivers DON'T support the Record type as a
return type.
So the next question is: is it possible to typecast a record
type to a ref cursor type in Oracle. In this way I can easily
change the return type for the stored procedures.

Hi ,
Can anybody tell me that is it possible to invoke Oracle stored Procedure from within a JDBC sender channel for PI 7.1.
Its working in XI3.0 and XI 7.0 for Oracle DBMS versions >= 10.2.x. But I am not sure,whether it will work for PI 7.1 also.
Thanks & Regards,
