Executing a stored procedure from a java program

Hi.. how can i call a oracle stored procedure from a java
program. the OSP has four IN parameters and one OUT parameter(a
cursor). when i try this way.. i get an error
con = DriverManager.getConnection(url, "stored", "stored");
CallableStatement cs =
con.prepareCall(
"{call stored_proce_1(?,?,?,?,?)}");
cs.registerOutParameter(1, OracleTypes.CURSOR);
cs.setString(2, "14541");
cs.setString(3, "gen");
cs.setInt(4, 0);
cs.setInt(5, 5);
ResultSet rs =cs.getResultSet();
while(rs.next()){
System.out.println(rs);
appreciate ur help.

I'm no expert on this, but I have a similar call where I fetch
an Oracle REF CURSOR from a call to a stored function. If you
fetch the cursor as an Object from your CallableStatement, you
can then cast it to a ResultSet e.g.
mystatement.executeUpdate();
ResultSet rs = (ResultSet) mystatement.getObject(1);
Then you should be able to loop through your ResultSet as usual.
Good luck!

Incorrect Update Count by executing a stored procedure from Java

Hi Guys,
I am calling a stored procedure from the java program which is modifying the rows of a table. Now I want to know how many rows have been modified by executing the stored procedure. I am writing the following code for the purpose:
OracleCallableStatement stmt =
(oracle.jdbc.driver.OracleCallableStatement)con.prepareCall("{callsp_um_setForumID(?,?)}");
stmt.setInt(1,101);
stmt.setInt(2,666);
n = stmt.executeUpdate();
System.out.println(n + " row(s) updated");
This procedure is actually modifying the table(When I query the databse it has modified 1 row). But it is returning a value 0 and is printing "0 row(s) updated".
Is there a way by which I can find out the number of rows updated by executing the stored procedure?
Thanks

Cannot call ANY stored functions from my Java program

My problem is that I cannot call ANY stored procedure from my Java
program. Here is the code for one of my stored procedures which runs
very well in PL/SQL:
PL/SQL code:
CREATE OR REPLACE PACKAGE types AS
TYPE cursorType IS REF CURSOR;
END;
CREATE OR REPLACE FUNCTION list_recs (id IN NUMBER)
RETURN types.cursorType IS tracks_cursor types.cursorType;
BEGIN
OPEN tracks_cursor FOR
SELECT * FROM accounts1
WHERE id = row_number;
RETURN tracks_cursor;
END;
variable c refcursor
exec :c := list_recs(11)
SQL> print c
COLUMN1 A1 ROW_NUMBER
rec_11 jacob 11
rec_12 jacob 11
rec_13 jacob 11
rec_14 jacob 11
rec_15 jacob 11
Here is my Java code:
import java.sql.*;
import java.io.*;
import oracle.jdbc.driver.*;
class list_recs
public static void main(String args[]) throws SQLException,
IOException
String query;
CallableStatement cstmt = null;
ResultSet cursor;
// input parameters for the stored function
String user_name = "jacob";
// user name and password
String user = "jnikom";
String pass = "jnikom";
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
try { Class.forName ("oracle.jdbc.driver.OracleDriver"); }
catch (ClassNotFoundException e)
{ System.out.println("Could not load driver"); }
Connection conn =
DriverManager.getConnection (
"jdbc:oracle:thin:@10.52.0.25:1521:bosdev",user,pass);
try
String sql = "{ ? = call list_recs(?) }";
cstmt = conn.prepareCall(sql);
// Use OracleTypes.CURSOR as the OUT parameter type
cstmt.registerOutParameter(1, OracleTypes.CURSOR);
String id = "11";
cstmt.setInt(2, Integer.parseInt(id));
// Execute the function and get the return object from the call
cstmt.executeQuery();
ResultSet rset = (ResultSet) cstmt.getObject(1);
while (rset.next())
System.out.print(rset.getString(1) + " ");
System.out.print(rset.getString(2) + " ");
System.out.println(rset.getString(3) + " ");
catch (SQLException e)
System.out.println("Could not call stored function");
e.printStackTrace();
return;
finally
cstmt.close();
conn.close();
System.out.println("Stored function was called");
Here is how I run it, using Win2K and Oracle9 on Solaris:

Thank you for your suggestion.
I tried it, but got the same result. I think the difference in the syntax is due to the Oracle versus SQL92 standard
conformance. Your statament is the Oracle version and mine is the SQL92. I think both statements are acceptable
by the Oracle.

Error while executing a stored procedure from forms6i

When I execute a STORED PROCEDURE from ORACLE DB 10g this procedure works perfectly fine.
But when I execute the same from the FORMs 6i I get the following error:
PDE-PLU022 Don't have access to the stored program unit
XMLPARSERCOVER in schema CARE.
where XMLPARSERCOVER is the class and
CARE is the schema.
Regards,
Jignesh S

I have tried this with both the owner of the schema and the intended user, -from both forms and directly.
All rights was granted on the stored procedure. Since posting I have found that one of the tables that the procedure might insert into, was not explicitly granted to the intended user, and after rectifying that the error message went away.
-however, the procedure now silently "finishes" without any evidence that it ever ran, if invoked from the forms application. When invoked from SQL Plus (or JDev, or Toad) it runs as expected.
I have no public synonym for the procedure, -is that necessary?
The stored procedure in question is implemented in java, and published as a stored procedure. It does rather heavy lifting, when running, using a view against another server , updating local tables and quite a lot of data validation/cleansing, and logging. All recourses are within the same schema.
Any ideas?

Error ORA-04031 while executing a stored procedure from Pro C++ code

I am getting the error ORA-04031(Unable to allocate 4096 bytes of shared memory("Shared Pool",.....)) while trying to execute a stored procedure from my pro*C application. This happens only after a few hours since the application has been running. I am closing the cursor after every database call.
Does anyone know why it is happening and any possible solutions?
TIA
Srithaj.

One thing that can be done is to flush the shared pool before starting the application.
alter system flush shared pool;
Another is to increase the shared pool size by setting the parameter shared_pool_size in init_sid.ora file.

How can I execute a batch file from my java program

Hi,
Can someone help me or direct me to a link,
How can I execute a DOS batch file from my java program?
Thanks

You will need to grab a handle to the process's
outputstream so u can see its output.The OP didn't mention any output from any batch file;
nor any input for that
matter,so lets not complicate matters here for now
ok?Actually I think this is essential to see whether it works or not. It's either that or do some manual check to see whether it ran, which is not exactly elegant, and in some cases this may not be easier than simply writing the output stream code, or in fact it may be impossible to check manually.
I'm sure it wasn't intentional that your post appeared to be bristling with attitude.

Execute oracle stored procedure from C# always returns null

Hi,
I'm trying to execute a stored procedure on oracle 9i. I'm using .Net OracleClient provider.
Apparently, I can execute the stored procedure, but it always returns null as a result (actually all the sp's I have there returns null)! I can execute any text statement against the database successfully, and also I can execute the stored procedure using Toad.
This is not the first time for me to call an oracle stored procedure, but this really is giving me a hard time! Can anyone help please?
Below are the SP, and the code used from .Net to call it, if that can help.
Oracle SP:
CREATE OR REPLACE PROCEDURE APIECARE.CHECK_EXISTENCE(l_number IN NUMBER) AS
v_status VARCHAR2(5) := NULL;
BEGIN
BEGIN
SELECT CHECK_NO_EXISTENCE(to_char(l_number))
INTO v_status
FROM DUAL;
EXCEPTION WHEN OTHERS THEN
v_status := NULL;
END;
DBMS_OUTPUT.PUT_LINE(v_status);
END CHECK_CONTRNO_EXISTENCE;
C# Code:
string connStr = "Data Source=datasource;Persist Security Info=True;User ID=user;Password=pass;Unicode=True";
OracleConnection conn = new OracleConnection(connStr);
OracleParameter param1 = new OracleParameter();
param1.ParameterName = "v_status";
param1.OracleType = OracleType.VarChar;
param1.Size = 5;
param1.Direction = ParameterDirection.Input;
OracleParameter param2 = new OracleParameter();
param2.ParameterName = "l_number";
param2.OracleType = OracleType.Number;
param2.Direction = ParameterDirection.Input;
param2.Value = 006550249;
OracleParameter[] oraParams = new OracleParameter[] { param1, param2 };
OracleCommand cmd = new OracleCommand("CHECK_EXISTENCE", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddRange(oraParams);
conn.Open();
object result = cmd.ExecuteScalar();
conn.Close();

Hi,
Does that actually execute? You're passing two parameters to a procedure that only takews 1 and get no error?
Your stored procedure doesnt return anything and has no output parameters, what are you expecting to be returned exactly?
If you're trying to access V_STATUS you'll need to declare that as either an output parameter of the procedure, or return value of the function, and also access it via accessing Param.Value, not as the result of ExecuteScalar.
See if this helps.
Cheers,
Greg

Execute Oracle Stored Procedure from Excel

Yes. You can use Oracle Objects for OLE to accomplish this. It comes with Excel examples and an online help file with many more examples.

Execute APEX stored procedure from outside APEX

I am looking at developing an application in APEX, but there needs to be a batch component that I would like to call from our corporation's scheduler. Is there a way for me to call an APEX stored procedure from a 3rd party scheduling software?
We use this method on all other oracle databases here, but are new to using APEX.
Thank you,
Trevor

This applicaiton is for the internal administration of an External database.
So there is an external web application that will have a user sign in, and request some transactions. These requests need to be brought inside our firewall to the APEX tables, where our admin staff will access the requests via this internal administrative applicaiton. It will tie into our Customer Information System, giving our staff all the data they need in one application. Requested transactions, and customer information. Once processed, the status of each transaction will be pushed back out to the external database for our customers to view.
The transfer of data, along with some other logic, is written in PL/SQL stored procs. To keep within our devlopement guidleines, I would like to kick them off using our existing scheduler. That way I only have one internal database to worry about.

Error executing a stored procedure from SSIS using the MERGE statement between databases

Good morning,
I'm trying to execute from SSIS a stored procedure that compares the content of two tables on different databases in the same server and updates one of them. To perform this action, I've created a stored procedure in the destination database and I'm
comparing the data between tables with the MERGE statement. When I execute the procedure on the destination database the error that I obtain is:
"Msg 916, Level 14, State 1, Procedure RefreshDestinationTable, Line 13
The server principal "XXXX" is not able to access the database "XXXX" under the current security context."
Some things to take in account:
1. I've created a temporary table on the same destination database to check if the problem was on the MERGE statement and it works fine.
2. I've created the procedure with the option "WITH EXECUTE AS DBO".
I've read that it can be a problem of permissions but I don't know if I'm executing the procedure from SSIS to which user/login I should give permissions and which.
Could you give me some tip to continue investigating how to solve the problem?
Thank you,
Virgilio

How to execute an stored procedure from the Report Region

Have stored procedure "LER_KRONOS_PAYCODE_HOURS_P" compiled and ready.

END;

ORA-06550: line 11, column 12: PLS-00103: Encountered the symbol "LER_KRONOS_PAYCODE_HOURS_P" when expecting one of the following: := . ( @ % ; immediate The symbol ":=" was substituted for "LER_KRONOS_PAYCODE_HOURS_P" to continue.

You need the execute keyword only when you run it directly from sqlplus.. that will tell sqlplus to append the keyword begin and end after the procedure call.
Example.
SQL > exec proc1 (input1);
will tell sqlplus to run it as a block.. saying
sql> Begin
proc1(input1);
end;Inside the procedure , in your code, you dont need the execute keyword.
But, why do you want to execute a procedure inside the source for a report region..?

Is it possible to execute a stored procedure from application express?

I have created a pl/sql application now I would like to give it a front end, I am new to application express.
My application depends on running a couple of pl/sql procedures that modify data.
What I need is my user to be able to execute the procedures from the application in a browser, is it possible to run a pl/sql procedure from an application express application in a browser?
how would I go about doing this?
thank you very much.
Ramiro

You sure can.
If you want to run a PL/SQL procedure/package/function from the URL, create a specific DAD entry just for that (Oracle) user, and give that user EXECUTE permissions on the procedure. Then just use the new DAD with the procedure name, like http://myserver.somewhere.com/MyNewDAD/Schema_Owner.MyPackage.MyProcedure?InParameter=MyParameter)
Of course, the above line will need heavy modification on your end, but I do this in my app, but I actaully pass it through a javascript attached to a button which then opens it in a new window.
If instead, all you want to do is execute a procedure with ApEx as part of a validation or process or something, select the PL/SQL 'Region' (or process, whatever it is you want to do), and then write it as an anonymous block:
begin
MyProcedure;
end;

Executing a shell script from a java program

Hi,
I'm facing a problem while executing a shell script from a jsp page.
I'm using exec() function.
It's working fine for single statement scripts.But if the script consists of any database processing and some other processing statements,it's not returning the correct exit status of the process.
Will u please help me in this.
If there is any other ways to execute a shell script from a jsp page other than Runtime.exec().If so let me know.
Thanks in advance.

I think this shud workMaybe - but it is wrong! Why do you create aReader
and then read bytes which are turned into a String
without worrying about whether or not the bytes area
String and without worrying about the character
encoding if the bytes do represent characters and
without worrying about how many bytes wereactually
read.
Also, both you and the OP should read, digest and
follow the advice given in
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-
traps.htmlI dont care if it is wrong. This code works for me.
We are here to solve problems not to find which post
is wrong.It is wrong! You are posting bad advice that is very wrong! It may work for you but it is wrong in general! WRONG WRONG WRONG.
If you have a solution then post it I did post a solution! The reference I gave will explain to you and the OP exactly how it should be done.
rather then
posting rude comments.I was not rude! I was explaining just some of what was wrong!
