Pass arrays from Java to PL/SQL procedure.

Hi All,
Can some body give an example, where an array of strings is passed from java to a PL/SQL procedure.
Any help in this regard is appreciated.
Thanks,
Prashant

I would want to use Oracle provided (Oracle Extensions) API to pass arrays to PL/SQL

to 'WLConnection'. Now, weblogic strongly suggest NOT to use this,as pooling capabilities
will be disabled.
But by setting RemoveInfectedConnectionsEnabled to false, we can ask weblogic
to return the Physical Connection to Pool. I have tested this with the attached
code. I DON'T find any issue.Good. The only real risk to obtaining the physical connection is retaining and
using it beyond the current thread execution. Your code looks OK. The only thing
I'd suggest is to add to the finally block. I would put a separate try-catch-ignore
block around every action in the finally, so if one fails, the others are still
done.
As long as you're writing good JDBC like that, there is no risk to telling the
pool to trust the code, by setting RemoveInfectedConnectionsEnabled to false.
That way you'll retain all the performance of the pools.

Note : Please look at the sample code that I am using. I AM NOT GOING TO USE PHYSICAL
CONNECTIONS for normal operations. I will use Physical Connection only when I
want to pass Arrays to Oracle.

Passisng array from Java into PL/SQL procedure

Hi everybody!
I have type created with :
CREATE OR REPLACE TYPE my_type IS TABLE OF number;
Next I have procedure withinin a package which has parameters:
PROCEDURE my_proc
(p_Result OUT NUMBER,
p_Id table.column%TYPE,
p_MyType my_type
I call this procedure from Java :
import javax.sql.*;
import java.sql.*;
import oracle.jdbc.*;
import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;
public class MyClass extends QueryClient {
private int Id;
private int type;
private Integer[] List;
private int result;
public MyClass(int Id, eType type,
Integer[] List) throws SQLException {
this.Id = Id;
this.type = (type.equals(eType.TYPE_EXPORT) ? 1 : 0);
this.List = List;
this.execute("{call my_package.my_proc(?,?,?,?)}");
public void body(CallableStatement stmt) throws SQLException {
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor("MY_USER.MY_TYPE", getCon());
ARRAY array_to_pass = new ARRAY(descriptor, getCon(), this.List);
// register the type.
stmt.registerOutParameter(1, OracleTypes.NUMBER); // result of procedure calling
stmt.setInt(2, this.Id );
stmt.setInt(3, this.type);
stmt.setArray(4, array_to_pass);
// execute and retrieve the result set
stmt.execute();
this.result = stmt.getInt(1);
public int getResult() {
return result;
EVERYTHING WORKS FINE, BUT when I move type "my_type" into package header
TYPE my_type IS TABLE OF number;
I receive error after calling procedure
java.sql.SQLException: invalid name pattern: MY_USER.MY_TYPE
I dropped type my_type after moving it into package. So there is only one my_type, in the package.
User who call procedure is owner of the package.
So questions are:
1. Is it possible to have my_type within package without error?
2. Is it possible to describe my_type without having a connection to database? My aim is eliminate number of connections to database.
Thanks all.
Matus.

You can't use the packaged type for this. You need to use the original collection type (i.e. via the CREATE TYPE syntax) as you have discovered yourself.

Is it possible to pass blob from java to PL/SQL ?

Hi, I try to bind a PL/SQL function who return a blob to a java class :

/In java code, my blob has the right size (150 Ko) but in PL/SQL, size = 0 !!!
Any ideas ?

Passing an array from Java to Pl/SQL Procdures

I am relatively new to the Java world and I am unable to pass back an array from Java back to the calling PL/SQL procedure. I have read many of the posts that deal with this issue and in specificly have viewed Ask Tom. My main issue is trying to get the data types matched up. I am able to return varchar2, numbers, and the like, but an array of filenames is not happening. I have tried a variety of "types" but unable to accomplish the task. Please help.
I have my Java class basically defined as:
public static oracle.sql.ARRAY[] getCollection(String directory)
throws SQLException
{ // provide a directory and get a listing of files
File path = new File( directory );
String[] list = path.list();
return list;
SQL Type and PL/SQL Procedure is:
CREATE OR REPLACE TYPE PTO_FILE IS TABLE OF VARCHAR2(100);
create or replace function get_dir_collection( p_directory in varchar2 ) RETURN PTO_FILE
as language java
name 'DirCollection.getCollection( java.lang.String ) return oracle.sql.ARRAY[]';
/

I know that it is not an ARRAY. It is however an "array" and I am attempting to map Java's String[][ to some "object" on the oracle side. I have looked at the link you sited and was not able to find the data mapping. I have found that mapping data types between different "languages" is some of the most difficult aspects of working with multiple languages.
Any suggestions? Thanks

URGENT: Passing Array from JSP to a Stored Procedure

Hi,
Can some one please help me understanding how can I pass array from JSP page to a stored procedure in database.
Thanks in advance.
Jatinder

Thanks.
I tried ArrayExampla.java and was successful in passing array values to the stored database procedure.
How can I use this class in JSP? Like I have first JSP where in I will collect input from the user and then submit it to the second JSP - that needs to call the ArrayExample.java to pass the values as array to the database.
How should I call this java code in my second JSP?
Thanks in advance.

ORA-00932 when trying to pass ARRAY from Java SP to PL/SQL

Hi all
I am trying to pass ARRAYs back and forth between PL/SQL and Java stored procedures. But I keep getting:

ARRAY ARRSentences = new ARRAY (arrayDesc, conn, arrSentences);
return ARRSentences;
I have confirmed that the String[] arrSentences contains a valid string array. So the problem seems to be the creation and passing of ARRSentences.
I have looked at pages and pages of documents and example code, and can't see anything wrong with my declaration of ARRSentences. I'm at a loss to explain what's wrong.
Thanks in advance - any help is much appreciated!

How to Pass String array from Java to PL/SQL and this use in CURSOR

hi,
I cant understand how to pass Array String as Input Parameter to the Procedure and this array use in Cursor for where condition like where SYMPTOM in( ** Array String **).
This array containing like (SYMPTOM ) to be returned from the java to the
pl/sql (I am not querying the database to retrieve the information).
I cannot find an example on this. I will give the PL/SQL block
create or replace procedure DISEASE_DTL<*** String Array ***> as
v_SYMPTOM number(5);
CURSOR C1 is
select distinct a.DISEASE_NAME from SYMPTOM_DISEASE_RD a
where ltrim(rtrim(a.SYMPTOM)) in ('Fever','COUGH','Headache','Rash') ------- ***** Here use this array element(like n1,n2,n3,n4,n5..) ******
group by a.DISEASE_NAME having count(a.DISEASE_NAME) > 3 ----------- ***** 3 is no of array element - 1 (i.e( n - 1))*****
order by a.DISEASE_NAME ;
begin
for C1rec IN C1 loop
select count(distinct(A.SYMPTOM)) into v_SYMPTOM from SYMPTOM_DISEASE_RD a where A.DISEASE_NAME = C1rec.DISEASE_NAME;
insert into TEMP_DISEASE_DTLS_SYMPTOM_RD
values (SL_ID_SEQ.nextval,
C1rec.DISEASE_NAME,
(4/v_SYMPTOM), --------**** 4 is no of array element (n)************
(1-(4/v_SYMPTOM)));
end loop;
commit;
end DISEASE_DTL;
Please give the proper solution and step ..
Thanking you,
Asish

I've haven't properly read through your code but here's an artificial example based on a sql collection of object types - you don't need that, you just need a type table of varchar2 rather than a type table of oracle object type:

Passing array from java stored procedure to plsql

I have a java store procedure that is parsing an xml document and returning element values to my plsql application(8.1.7). I'm mapping a java.lang.String return type to VARCHAR2. However I'm running into the 4k limit when trying to return a string from java that is over 4k. Truncation of varchar returning over 4k is a known issue in 8i.
So my next idea was to split that value of the element into 2000char and put in an array then pass that back to the plsql procedure. I know that oracle.sql.ARRAY can be converted into a plsql TABLE. But I believe you can only use the oracle.sql.ARRAY type when you are doing jdbc programming and are working with a connection.
SO FINALLY MY QUESTION IS...
Can anyone think of a solution that will allow me to pass over 4k of character data from my java stored procedure (not jdbc), back to my plsql app?
Thanks.

My understanding is that oracle 8 has a 4k limitation on any plsql function return data. A varchar can hold 32k within a function/package, but it cannot return more than 4k outside it's scope.
Do you have an example you could share where you use the clob as a return type?
Thanks!

Passing a structure from Java to PL/SQL Procedure

Environment: Oracle DB, Tomcat/Apache
How do we pass a structure (Table Record Type) from Java to a PL/SQL Stored Procedure?
We are doing JSP-->JavaClass/Bean to communicate to DB. We have an existing PL/SQL packages/Procedure to insert records into table (These procedures have record types as in/out parameters). So is there a way to call these from Java?
Thanks in advance.

Oracle9 i JDBC Developers Guide and Reference(page 21-16):
It is not feasible for Oracle JDBC drivers to support calling arguments or return
values of the PL/SQL RECORD, BOOLEAN, or table with non-scalar element types.
However, Oracle JDBC drivers support PL/SQL index-by table of scalar element
types. For a complete description of this, see "Accessing PL/SQL Index-by Tables"
on page 16-21.
As a workaround to PL/SQL RECORD, BOOLEAN, or non-scalar table types, create
wrapper procedures that handle the data as types supported by JDBC. For example,
to wrap a stored procedure that uses PL/SQL booleans, create a stored procedure
that takes a character or number from JDBC and passes it to the original procedure
as BOOLEAN or, for an output parameter, accepts a BOOLEAN argument from the
original procedure and passes it as a CHAR or NUMBER to JDBC. Similarly, to wrap a
stored procedure that uses PL/SQL records, create a stored procedure that handles
a record in its individual components (such as CHAR and NUMBER) or in a structured
object type. To wrap a stored procedure that uses PL/SQL tables, break the data
into components or perhaps use Oracle collection types.

Passing String Array from Java to PL/SQL

Hi,
We are having couple of packages which have been written in PL/SQL . I would like to know how i can send arrays as input parameters from Java to any stored proc in Oracle. I am having Oracle 8i as the DB and am using Websphere RSA for deployment purposes.
please find below Java , PL/SQL code and exception

BEGIN
dbms_output.put_line('in_Commodity_tab(' || '0' || ') : ' || in_Commodity_tab(0) );
Java Code :
CallableStatement cstmt=null;
Connection conn=null;
try{
conn=getConnection();
System.out.println("++++++connected");
String sqlStr = "{call Pkg_Surcharge.RETRIEVE_CHARGES(?) }";
cstmt = conn.prepareCall(sqlStr );
//1.

Avi is correct. You must create a varray or nested table instead of using a PL/SQL index-by table.
SQL> create type commodity_key as varray(#) of varchar2(500);
or
SQL> create type commodity_key as table of varchar2(500);
Use the varray if you know the number of items in the array. Otherwise, use the nested table.

Passing XML from Java to PL/SQL using CLOBs?

Hi. Here at the University at Buffalo, we're trying to develop an architecture where departments can send XML transactions to the business offices over HTTP. Since we don't have much Java expertise on staff, the boss has decided that we should use PL/SQL wherever possible. To that end, I have a Java servlet that calls PL/SQL stored procedures using JDBC.
My question is this: We anticipate that we will have the need to process documents larger than the limit on VARCHAR2 data. However, unless I am misunderstanding the documentation on working with LOBs, the LOB itself must already exist in the tablespace. How will I take the XML document I receive through the servlet and pass it through to the PL/SQL function which accepts it? This function, FYI, routes documents to various systems based on document type, checks user security, and does a bunch of other things before the XML document is committed to a table.
Is this possible? If there are already resources available that answer my question, can you point me in the right direction?

You has to use temporary CLOB for this purpose.
If you needs some kind of examples I'll sent to you directly the codes.

Passing XMLDocument from Java to PL/SQL

Hi - I'm running Oracle 9i Release 2 on Windows 2000 and 9Ias on Windows2000.
I have a class loaded into the DB with LoadJava which accesses a Servlet on the Appserver which returns a XML document. The class in the DB is wrapped by PL/SQL function.
The PL/SQL function is the initiator of the transaction - ie sequence as follows:
Client calls function - calls class in DB - calls Servlet - calls EJB - same route back. I do have a valid XMLDocument in the class after the call but can't get this back into the DB.
I have tried with XMLType but resulted in ora-600 errors and ultimately crashing the DB. Any suggestions as how to get the XMLDocument in?
Tks
code Snipets:
java code - this is the way I had checked the valid xml document.. seemed fine - I then changed all the XMLDocument's to XMLType and crashed the DB!!
import oracle.xdb.XMLType;
import oracle.sql.OPAQUE;
class TestServlet
public static XMLDocument getIsis ()
System.out.println("Message to standard output - pos 1");
XMLDocument incomingXMLDoc = null;
URL target = null;
try
incomingXMLDoc = new XMLDocument();
String appServer = "http://sdt10645:8888/t1/servlet/Servlet1";
target = new URL(appServer);
incomingXMLDoc = XMLHttp.doPost(target);
// ((XMLDocument)incomingXMLDoc).print(System.out);
This is the PL/SQL function
PACKAGE AJK1CALLS AS
FUNCTION TestServletCall RETURN xmltype IS
LANGUAGE JAVA
NAME 'TestServlet.getIsis() return oracle.xdb.XMLType';
END ajk1Calls;
This is the pl/sql function call
DECLARE
doc1 xmltype;
BEGIN
doc1 := ajk1calls.testservletcall;
END;
Any help appreciated !!

Passing Array of java objects to and from oracle database-Complete Example

Hi all ,
I am posting a working example of Passing Array of java objects to and from oracle database . I have struggled a lot to get it working and since finally its working , postinmg it here so that it coudl be helpful to the rest of the folks.
First thinsg first
i) Create a Java Value Object which you want to pass .
create or replace and compile java source named Person as
import java.sql.*;
import java.io.*;
public class Person implements SQLData
private String sql_type = "PERSON_T";
public int person_id;
public String person_name;
public Person () {}
public String getSQLTypeName() throws SQLException { return sql_type; }
public void readSQL(SQLInput stream, String typeName) throws SQLException
sql_type = typeName;
person_id = stream.readInt();
person_name = stream.readString();
public void writeSQL(SQLOutput stream) throws SQLException
stream.writeInt (person_id);
stream.writeString (person_name);
ii) Once you created a Java class compile this class in sql plus. Just Copy paste and run it in SQL .
you should see a message called "Java created."
iii) Now create your object Types
CREATE TYPE person_t AS OBJECT
EXTERNAL NAME 'Person' LANGUAGE JAVA
USING SQLData (
person_id NUMBER(9) EXTERNAL NAME 'person_id',
person_name VARCHAR2(30) EXTERNAL NAME 'person_name'
iv) Now create a table of Objects
CREATE TYPE person_tab IS TABLE OF person_t;
v) Now create your procedure . Ensure that you create dummy table called "person_test" for loggiing values.
create or replace
procedure give_me_an_array( p_array in person_tab,p_arrayout out person_tab)
as
l_person_id Number;
l_person_name Varchar2(200);
l_person person_t;
l_p_arrayout person_tab;
errm Varchar2(2000);
begin
     l_p_arrayout := person_tab();
for i in 1 .. p_array.count
loop
     l_p_arrayout.extend;

commit;
EXCEPTION WHEN OTHERS THEN
     errm := SQLERRM;
     insert into person_test values(-1, errm);
     commit;
end;
vi) Now finally create your java class which will invoke the pl/sql procedure and get the updated value array and then display it on your screen>Alternatively you can also check the "person_test" tbale

and thats it. you are done.
Hope it atleast helps people to get started. Comments are appreciated. I can be reached at ([email protected]) or [email protected]

Hi Sunil,
I've a similar situation where I'm trying to insert Java objects in db using bulk insert. My issue is with performance for which I've created a new thread.
http://forum.java.sun.com/thread.jspa?threadID=5270260&tstart=30
I ran into your code and looked into it. You've used the Person object array and directly passing it to the oracle.sql.ARRAY constructor. Just curios if this works, cos my understanding is that you need to create a oracle.sql.STRUCT out of ur java object collection and pass it to the ARRAY constructor. I tried ur way but got this runtime exception.

                    at JavaBulkInsertNew.main(JavaBulkInsertNew.java:76)
Here's a code snippet I used :
Object optionVal[] =   {optionArr[0]};   // optionArr[0] is an Option object which has three properties
oracle.sql.ArrayDescriptor empArrayDescriptor = oracle.sql.ArrayDescriptor.createDescriptor("TT_EMP_TEST",conn);
ARRAY empArray = new ARRAY(empArrayDescriptor,conn,optionVal);If you visit my thread, u'll see that I'm using STRUCT and then pass it to the ARRAY constructor, which works well, except for the performance issue.
I'll appreciate if you can provide some information.

Passing parameters from java jdbc to pl/sql

I’m calling stored procedures from java jdbc… but looking for nicer interfaces in terms of passing data. Has anyone come up with a good way to pass data from java jdbc to pl/sql without passing a million parameters? I’m thinking here of some type of structure like pl/sql rowtype or table index type or something else. Has anyone tried to create typed objects in oracle databases and access them from java?
Thanks, Patrick Caldwell

Hi Patrick,
Yes, I have created an Oracle object type, which I successfully returned to a java class, from a PL/SQL stored function, using JDBC. Environment was J2SE 1.3.1, with Oracle 8.1.7.4 on SUN [sparc] Solaris 7 with Oracle's JDBC (thin) driver. It was a while ago, so I don't remember the details very clearly, but I recall being able to figure it out quite easily using the Oracle documentation and the sample code available at Oracle's Technet Web site.
Hope this has helped you.
Good Luck,
Avi.
