Dear
Sir/madam
From java its easy to call procedure or function to get pl/sql variables like cursor type or varray type and cast back to that equi type thro' oracle extn package.Is there any way it could be done vice versa.Can i pass Oarcles Pl/SQL datatype like collection Of type Varray/Custom Object or Cursor,Array type to a procedure or function from java program.Is it possible to pass like that.If so could you kindly give a samll eaxample or URL where same type of example could be found

Pass PL/SQL Record variable to Stored procedure in Java

Can some one please give me a code snippet for passing a Record Type variable returned by Stored Procedure. Following is the scenario.
A record type variable REC_VAR is made of three columns of a table as follows
EmpNo Number, Empname Varchar2(50), Zip_Code Varchar2(5).
I am populating this variable in Java code and passing it to Stored Procedure.
Can I referance Record Type variable in a Oracle package from Java code.
How would I define these variables as per tables column type and pass to SP in a java program.
Thanks,

Pass BPC SSIS variable to stored procedure

Dear All
We have a ssis package in which there is data flow task. There
is a OLEDB source which uses “Data access mode” as sql command. We used OLEDB data source instead of execute sql task as the outuput is table format generated in Stored proc which is used in following task
This task calls a stored procedure with a input parameter which will be appset name.   [EXEC ProcName '@BPCAPPSET']
The stored procedure is executing fine without any issues.But when I pass variable containing appset name to that stored procedure its not taking properly and package ending successful.
The variable is “BPCAPPSET” it contains appset name which
will be taken front end.
   However to test if this value is taken by stored procedure
or not, I tried to hardcode and pass appset name to stored procedure. i.e exec
ProcName Appset1.
Appset1 is existing appset. It worked fine. But we want to
put this package in all land scapes, such that whenever it is triggered it will
take the appset as parameter and does the calculation in stored procedure.
   Please advice how to pass this variable to stored
procedure.
regards
Prasad

Hi Roberto
Thanks for your mail.
I have tried, but I am getting error that @BPCAPPSET scalar
variable must be defined.
I believe that @BPCAPPSET is system defined variable which
will be passed from Data manager package. May be this is the reason it is not
recognizing this variable?
If so, should I define a variable in SSIS. How can we
assign value of @BPCAPPSET to the newly defined variable?
Please advise. Attached screenshot.

Passing Pl/Sql variables into shell variables.

I have written a file that ftp information from one pc to another in unix.
All you have to do is supply a user_name/password and machine name to which ftp program will connect to.
All connection information like user_id,password, machine name are stored in an oracle table FTP_TBL.
It has the following fields:
FTP_TBL
================
USER_ID      NOT NULL VARCHAR2(100);
USR_PASSWD      NOT NULL VARCHAR2(50);
TO_MACHINE     NOT NULL VARCHAR2(50);
I have called a pl/sql script in unix shell.
This script selects all the connection information from FTP_TBL and populates the pl/sql variables with the
information.
Now i want the pl/sql variables like V_TO_MACHINE,V_USR_ID,V_USR_PASSWD to be passed on to unix variables
To_MACHINE, USR_ID AND USR_PASSWD.
How can i do this?
============================================================================================================
sqlplus -s <<+++ >> $LOG_FILE
$USER/$PASSWD
set serverout on SIZE 1000000
DECLARE
V_TO_MACHINE VARCHAR2(100);
V_USR_ID VARCHAR2(50);
V_USR_PASSWD VARCHAR2(50);
BEGIN
     BEGIN
          SELECT TO_MACHINE, USER_ID, USR_PASSWD
          INTO V_TO_MACHINE,V_USR_ID,V_USR_PASSWD
          FROM FTP_TBL;
     EXCEPTION
          when others then
          dbms_output.put_line('ERROR|SQLPLUS|'||ERROR||'|'||sqlcode||'|Failed during selecting configuration information.'||sqlerrm );
     END;
END;

How to fetch %ROWTYPE OUT param of a stored procedure from Java program?

I have a stored procedure that has IN / OUT parameter as table_name%ROWTYPE.
From a java program how can I access this ROWTYPE variable?
I tried all possible documentation and none of the explains whether or not this is supported.
My use case expect exactly 1 record from the procedure and we would prefer not to use REF CURSOR.
Is there a way to achieve this? If so, can someone help me with it by posting the sample code to achieve this?
I tried all the possible OracleTypes to register the OutParameter and they all fail.
Looks like there isn't any equivalent of %ROWTYPE in OracleTypes either.
If you need, I can post my sample procedure that uses %ROWTYPE as OUT parameter.
I really appreciate your help in this regard.

Hi,
If "returning only 1 record" the showstopper for not using Ref Cursor, you might want to reconsider because as you probably know, the ref cursor is only a pointer and requires additional step to retrieve the data.

Passing pl/sql variables to javascript function

hi! in a dynamic page, i've got the javascript:

how can i pass in as onCall('12-Jun-2002','TestUser'), with the single quotes?
the above pass in as onCall(12-Jun-2002, TestUser) which the javascript will throw an error message.
thx.

hi! got it by chance:

How to call stored procedures from java program?

I have tried to run a program that calls a stored procedure on MySQL
server version 5.0.17 by using connector/j 5.0, but it always fails on the
statement: con.preparecall() ,
have looked on the internet and found out that people can all mysql
stored procedure all right in their programs, really dont know what's
wrong with this small peiece of code:
import java.sql.*;
public class TestDB {
      // procedure being called is:
     CREATE PROCEDURE `dbsaystorm`.`getsite` ()
     BEGIN
        select name from tblsite;
     END
     public static void main(String[] args) {
          try {
              //Class.forName("org.gjt.mm.mysql.Driver");
              Class.forName("com.mysql.jdbc.Driver");
              Connection con = DriverManager.getConnection("jdbc:mysql://localhost/dbname",
                        "user", "pwd");
       * executing SQL statement here gives perfect correct results:
        // PreparedStatement ps = con.prepareStatement("select name from tblsite");
        // ResultSet rs =ps.executeQuery();
              // but in stored procedure way...
              //it fails here on this prepare call statement:
              CallableStatement proc = con.prepareCall("call getsite()");
              ResultSet rs =proc.executeQuery();
              if (rs == null) return;
              while (rs.next()){
                  System.out.println("site name is: "+ rs.getString(1));
              rs.close();
          } catch (SQLException e) {e.printStackTrace();}
           catch (Exception e) {e.printStackTrace();}
}it always gives this exception:
java.lang.NullPointerException
     at com.mysql.jdbc.StringUtils.indexOfIgnoreCaseRespectQuotes(StringUtils.java:959)
     at com.mysql.jdbc.DatabaseMetaData.getCallStmtParameterTypes(DatabaseMetaData.java:1280)

     at saystorm.server.data.database.TestDB.main(TestDB.java:29)
where have I gone wrong?
when I commented out the statement that makes the procedure call and call preparedstatement to execute SQL select statement, it gave perfectly correct result.
it looks like there is no problem with java prog accessing MYSQL server database, but the it seems that it's just java can't call stored procedure stored on the mysql server version 5.
can it or can't it? if it can, how is that accomplished?

It is a bug in the driver because it shouldn't be
returning that exception (null pointer) even if you
are doing something wrong.
Are you using the latest version of the driver?
The stored procedure runs when you run it from the
gui/command line using a MySQL tool - correct?
As suggested you should be using the brackets. What
is the data type of the 'name' field?
You could try returning another value like one of the
following
select 1, name from tblsite;
select name, 1 from tblsite;
That might get around the bug
Additionally try just the following...
select 'test' from tblsite;yes, the driver used is in connector/j 5.0--the lastest one, and the
procedure can run correctedly at either command line or GUI mode
with no problem whatsoever, the returned data type is string type,
I have not got the chance to test it again with those values you
suggested, as I have abandoned the laptop I used to write that code
initately. There have been some other really weird cases happened on
that computer. I guess that must be something wrong with the JVM
installed on it, it was upgraded from jre5.0.04 to 06, and to 09.
something within hte JVM must have been messed up(the only reasonable
explanation). Because the same code runs correctly on my new laptop,
using the same environment: jvm 5.0_09, mysql 5.0.18, connector/J 5.0.
that old laptop really was a nightmare.

I can't do this, because result object is a Map, and I need write the Key of the Value to obtain.
So I can do:

Passing Null Characters from Unix Shell Script to Java Program

Hi Experts,
Facing an issue with a shell script....
The shell script has 10 input parameters....
1st Parameter is a compiled Java program name(This can keep changing)
Rest 9 are the parameters of the Java Program...
The following piece of code is working when Test "a z" "b t" "" "" "" "" "" "" "" "" is hardcoded.
lv_java_string=`java Test "a z" "b t" "" "" "" "" "" "" "" ""`
The whole thing being dynamic.....
But when I dynamically populate the same on to a parameter lv_java_param and then execute the same
lv_java_string=`java $lv_java_param`
if i echo $lv_java_param its giving me Test "a z" "b t" "" "" "" "" "" "" "" "" correctly
Im facing some issue...... The issue is " is being treated as a parameter itself and the space between a and z is not taken into consideration and hence z is taken as the 2nd parameter
Issue seems to be something like the precedence in which the above statement is executed, because of which "s are calculated/manipulated. Is it something like
a) $lv_java_param is computed first and then java $lv_java_param
b) or java $lv_java_param is run on the fly......
Any help is much appreciated.

Returning SQL cursor from Stored Procedure

Hi,
I have a query regarding returning sql cursor from stored procedure to java in oracle 11g.
I want to query some data ex: my query returns A, B, C. Also, now I want to query some other data ex: D, E, F. Now I want to return this data as an sql cursor as a single row . Example: A,B,C,D,E,F. Is it possible to return/create a cursor in stored procedure?
assume both query returns equal number of rows.. however both are not related to each other..

assume both query returns equal number of rows.. however both are not related to each other..It sounds like what you need is a ref cursor.
First thing to remember though is that cursors do not hold any data (see: {thread:id=886365})
In it's simplest form you would be creating a procedure along these lines...

How to pass Unix environment variable to a SQL procedure or SQL * Plus

How to pass Unix environment variable to a SQL procedure or SQL * Plus file..
I am trying to invoke a SQL Procedure from Unix

Is it possible..?
Thanks in advance.
Regards,
Srinivas Jaltaru

Within your shell script you can use what is known as a "here document" which is basically a way of wrapping a call to Oracle. The following call to Oracle loops and writes rows to files with numerically increasing file names. Two unix shell variables are used, one in a select statement and one in a spool command :
<pre>
#!/bin/bash
export ORACLE_SID=DEV05
FILENO=1007351
while [ ${FILENO} -le 1008400 ]
do
FILENAME=farm_${FILENO}.txt
DUMMY=`sqlplus -s user20/user20 <<SQLSTOP
set lines 73
set pages 0
set head off
set termout off
set echo off
set feedback off
select rpad(searchx, 8)
from blastx@PRODUCTION
where searchx = ${FILENO} ### here's a shell variable
spool /export/home/user20/sql/psiblast/BACKUP2_D/${FILENAME} ### here's a shell variable
spool off
SQLSTOP`
FILENO=`expr ${FILENO} + 1`
done
exit 0
</pre>

type rec_type is record (n number, d date, v varchar2(1));
rec rec_type;
procedure p (r IN rec_type);
end ;
Package body :
create or replace package body pkg is
procedure p (r IN rec_type) is
begin
dbms_output.put_line('The values passed to the procedure are' || r.n||r.d||r.v);
end p ;
end pkg;
Actual pl/sql Call (I need counter part of below code in Java)
declare
r1 pkg.rec%type;
begin
r1.n := 7; r1.d := sysdate; r1.v := 'R';
pkg.p(r1); -- > How to do similar call using OracleCallableStatement
end;
