Retriving an Array from an Oracle Procedure in Java

I have a procedure in Oracle which returns an VARRAY of VARCHAR2
I am Unable to get the Array back in the Servlet in my Application.....
I have tried this using normal thin driver and couldn't succed....
So I have tried with OCI driver then also i was unble to get the Array.
I have used ojdbc14.jar for OCI connection

thanks for the reply.
That is What I ma doing exactly.....
I am also placing the code here check it out......
My Oracle PL/SQL Code is here
===========================
CREATE OR REPLACE package types
as
type varray is VARRAY(10) OF VARCHAR2(100);
end;
CREATE OR REPLACE PROCEDURE getArray(userid IN VARCHAR2, arrayList OUT types.array)
IS
BEGIN
     arrayList(0) := 'Hello';
     arrayList(1) := 'Welcome';
END;
===========================
My Java Code is this
===========================
Class.forName("oracle.jdbc.driver.OracleDriver");
con=DriverManager.getConnection("jdbc:oracle:oci:lcms/lcms@GDBN");
stmt = (OracleCallableStatement) conn.prepareCall("begin :1 := getArray(?,?); end;");
stmt.setString(1,"abcd");
stmt.registerOutParameter(2, OracleTypes.ARRAY);
stmt.executeUpdate();
ARRAY simpleArray = stmt.getARRAY(1);
System.out.println("Array is of type " + simpleArray.getSQLTypeName());
System.out.println("Array element is of type code "+simpleArray.getBaseType());
System.out.println("Array is of length " + simpleArray.length());
System.out.println("======================================");
String[] values = (String[])simpleArray.getArray();
for( int i = 0; i < values.length; i++ )
     System.out.println( "row " + i + " = '" + values[i] +"'" );
This is what I am doing in My JAVA Code....
================================================
When I execute this I get an Error Message at Line
--->>>>stmt.registerOutParameter(2, OracleTypes.ARRAY);
Error Message is As follows....

Returing array from PL/SQL procedure

Hi,
I am trying to return array from PL/SQL procedure. Heres is the code. I am getting an error "OracleParameter.ArrayBindSize is invalid ".
Will anybody let me know what is wrong in following code. or does anybody have code to return PL/SQL array using VB.NET.
oCommand.CommandText = "MyPack.TestVarchar2"
oCommand.CommandType = CommandType.StoredProcedure
Dim id As Integer = 10
Dim deptname As String()
Dim oParam1 As Oracle.DataAccess.Client.OracleParameter = New Oracle.DataAccess.Client.OracleParameter("id", Oracle.DataAccess.Client.OracleDbType.Int32)
Dim oParam2 As Oracle.DataAccess.Client.OracleParameter = New Oracle.DataAccess.Client.OracleParameter("deptname", Oracle.DataAccess.Client.OracleDbType.Varchar2)
oParam1.Direction = ParameterDirection.Input
oParam2.Direction = ParameterDirection.Output
oParam1.CollectionType = Oracle.DataAccess.Client.OracleCollectionType.None
oParam2.CollectionType = Oracle.DataAccess.Client.OracleCollectionType.PLSQLAssociativeArray
oParam1.Value = id
oParam2.Value = ""
oParam1.Size = 10
oParam2.Size = 20
oCommand.Parameters.Add(oParam1)
oCommand.Parameters.Add(oParam2)
oCommand.ExecuteNonQuery()
Thanks

Thanks Arnold for the reply..
Yes, I am trying to get result set in array which is unknow to me (No of rows return by the query). For the test I will pre-define the result set so that I will able to set ArrayBindSize.
I have read C# example but when I try to write it in VB.NET it gives me syntax error when I try to set the ArrayBindSize.
oParam.ArrayBindSize = new int[3]{15,23,13} // individual max size of 3 outputsWill you please let me know how to set ArrayBindSize (VB.NET) because I am new to this..
There is an example at otn "How to: Bind an Array to an ODP.NET Database Command" which does multiple INSERTs in one trip to database. This works fine. I need to do same for the SELECT statement which will return me multiple rows. I do not mean refCursor. If I use refCursor, it will make soft parse which I am trying to avoid using this Array techniq.
Thanks

DBMS_OUTPUT.PUT_LINE multi records from PL/SQL procedure to Java web page.

Hello
I will explain the scenario:
In our java web page, we are using three text boxes to enter "Part number,Description and Aircraft type". Every time the user no need to enter all these data. The person can enter any combination of data or only one text box. Actually the output data corresponding to this input entries is from five Oracle table. If we are using a single query to take data from all the five tables, the database will hang. So I written a procedure "SEARCH1",this will accept any combination of values (for empty values we need to pass NULL to this procedure) and output data from all the five tables. When I executing this procedure in SQL editor, the execution is very fast and giving exact result. I used "dbms_output.put_line" clause for outputing multiple records in my procedure. The output variables are "Serial No, part Number, Description, Aircraft type,Part No1,Part No2,Part No3,Part No4". I want to use the same procedure "SEARCH1" for outputing data in java web page.The passing argument I can take from the text box provided in java web page. I am using jdbc thin driver to connect our java web page to Oracle 9i database.
Note1 : If any combination of search item not available, in procedure itself I am outputing a message like "Part Number not found". Here I am using four words ("Part" is the first word,"Number" is the second,"Not" s the third, and "found" is the fourth) for outputing this message.Is it necessary to equalise number of words I am using here to the record outputing eight variable?
Our current development work is stopped because of this issue. So any one familier in this field,plese help me to solve our issue by giving the sample code for the same scenario.
My Email-id is : [email protected]
I will expect yor early mail.

Associative Array problem in Oracle Procedure

Hi,
I've searched through the internet and this forum and haven't been able to resolve a problem using associative array values within an IN clause. Everything I've read states that I can't use the associative array directly in the SQL statement. I have to convert it to a table and then I can use it. Unfortunately, I'm receiving an "ORA-21700: object does not exist or is marked for delete" error when trying to access the table I've populated from the array. Please note that I have verified the table is actually being populated during the loop. I'm catching the error when referencing it in the SELECT statement.
I've declared the following in the ARCHIVE package specification:
TYPE RSType IS REF CURSOR;
TYPE integer_aat IS TABLE OF INTEGER INDEX BY PLS_INTEGER;
TYPE integer_table IS TABLE OF INTEGER;
The procedure is as follows:
PROCEDURE SEL_SEARCH_RESULTS (v_term IN VARCHAR2,
v_categories IN ARCHIVE.integer_aat,
rs OUT RSType)
AS
/* PURPOSE: Return Search Results for the Category and Keyword Provided
VARIABLES:
v_categories = Document Categories array
v_term = Keyword entered
rs = Result Set
tbl_cat ARCHIVE.integer_table := ARCHIVE.integer_table();
BEGIN
FOR i IN 1 .. v_categories.COUNT
LOOP
tbl_cat.EXTEND(1);
tbl_cat(i) := v_categories(i);
END LOOP;
OPEN rs FOR
SELECT A.ID,
B.CATEGORY,
A.FILENAME,
A.DISPLAY_NAME,
A.COMMENTS
FROM TBL_ARCHIVE_DOCUMENTS A,
TBL_ARCHIVE_DOC_CAT B,
TBL_ARCHIVE_DOC_KEYWORDS C
WHERE A.ID = B.ID
AND A.ID = C.ID
AND B.CATEGORY IN (SELECT * FROM TABLE(tbl_cat))
AND C.KEYWORD = v_term
ORDER BY A.ID;
END SEL_SEARCH_RESULTS;
Any help would be greatly appreciated and thanks in advance,
Matt

Thank you for the quick response. I looked at the example you suggested and made the following changes. Now I'm receiving an "Invalid datatype" error on the "SELECT column_value FROM TABLE(CAST(tbl_cat AS tbl_integer))" statement. I must be missing something simple and I just can't put my finger on it.
PROCEDURE SEL_SEARCH_RESULTS (v_term IN VARCHAR2,
v_categories IN ARCHIVE.integer_aat,
rs OUT RSType)
AS
/* PURPOSE: Return Search Results for the Category and Keyword Provided
VARIABLES:
v_categories = Document Categories array entered
v_term = Keyword entered
rs = Result Set
TYPE tbl_integer IS TABLE OF INTEGER;
tbl_cat tbl_integer;
BEGIN
FOR i IN 1 .. v_categories.COUNT
LOOP
tbl_cat.EXTEND(1);
tbl_cat(i) := v_categories(i);
END LOOP;
OPEN rs FOR
SELECT A.ID,
B.CATEGORY,
A.FILENAME,
A.DISPLAY_NAME,
A.COMMENTS
FROM TBL_ARCHIVE_DOCUMENTS A,
TBL_ARCHIVE_DOC_CAT B,

WHERE A.ID = B.ID

AND C.KEYWORD = v_term

How to pass a multidimensional array to an Oracle procedure?

How can I pass a multidimensional array to oracle array?
Thanx in anticipation,

Look in to passing user defined type back and forth to Oracle. Any type that oracle supports, you can constract on the java side and send it across. Look into the SQLData class.

for (i = 0; i < intReqID.Count(); i++) {
stat[i] = OracleParameterStatus.Success;
cmdVDL.Parameters["P_REQID"].ArrayBindStatus = stat;
cmdVDL.ExecuteNonQuery();
When I run this I get the following error:

PLS-00306: wrong number or types of arguments in call to 'PRC_VDM_SAVDEL_VEN_DOC'
ORA-06550: line 1, column 7:

If I remove the Associative Array from both, the procedure runs fine.
What am I doing wrong?

Additionally,
1) UDT support requires 11106.20 or higher ODP (but can be used against 10g db)
2) if the plsql is changeable, you may want to swap it to associative array instead to avoid having to create custom classes for the UDT, and here's a short sweet example.

Retrieving cursor from a stored procedure

Hi,
Is there any means to retrieve a cursor from a stored procedure using java.sql.* package, without using database specific type code like OracleTypes.CURSOR?
Regards,
Shalin.

Hi,
I had some across this problem some time ago. Although, there is no direct answer to this solution, there is a "kloog" that you can apply.
Please note that the signature for registerOutParameter(int parameterIndex, int sqlType), and note that where ever sqlType is mentioned it is an int.
Now JDBC is an interface and the implementation is given by Oracle. So to register an "out" parameter all you have to do is registerOutParameter(1, OracleTypes.CURSOR). It works!
Or otherwise try and find out what the int value of CURSOR is and replace. This is because not all databases can support returning a "cursor" type, since ORACLE and few other databases have a concept of "STORED PROCEDURE" and PLSQL is specific to ORACLE.
I hope this helps!
Cheers,
John.

PL/SQL Procedure and Java

Hi All,
I am working on a Data Warehousing Product and generating Web Reports.
These Web Reports are JSPs.
The basic architechture used for this is :
1. Get the inputs required for Report Generation through a Web GUI
2. Validate and Process (If Valid) the inputs so that it can be applied on the Data in the DB to fetch appropriate information.
3. The Data from the DB is retreived in the form of PL/SQL Procedures, which take the Processed information from Step 2 as Input and give the Output in the form of REF CURSORS.
Note: There are a many PL/SQL Procedures that are being executed, based on the configuration the Client has set. This configuration enables the Client to set the columns he wants to see in the Web Reports. This configuration is set before the Reports are run.
4. A call is made from Java to Oracle, each time a PL/SQL Procedure need to be executed. The REF CURSOR received as an Output from the PL/SQL Procedure is processed.
5. The next PL/SQL Procedure is called (if existing), else the Processed Data (from REF CURSOR Output) is displayed in the JSP as Web Reports.
The issue with above architechture is the PERFORMANCE.
I would like to know:
- The various ways in which data can be EFFICIENTLY & QUICKLY retrieved from PL/SQL Procedure in Java.
- Are there any APIs that improve the Java-Oracle Data Fetch Efficiency
- Is there any Java Framework available that can be used to increase the spped of Web Report generation.
- Do you suggest any changes in the above mentioned architechture, that make this work a Sweet Sixeen Year olg guy! ;)
- In general, any input that can increase the Speed of Web Report Generation.
Kindly let me know if I have not been clear at any point, so that I can re-explain the same more clearly.
And the most important thing, kindly scrap down your thoughts about the same.
Thanks a lot in advance for your VALUABLE INPUTS.
- Vikas

Handling a List returned from a Stored Oracle Procedure

I'm trying to put a PL/SQL oracle wrapper around some post code lookup
software.
We're planning to get the wrapper to return a List and then JDBC to handle this list.
Has anyone already done/attempted to do this? Does anyone know if it can be done using a List and can oracle stored procedures return a List?

It appears that Oracle does support an array type:
In Oracle
CREATE OR REPLACE FUNCTION getEmpArray RETURN EMPARRAY
AS
l_data EmpArray := EmpArray();
CURSOR c_emp IS SELECT ename FROM EMP;
BEGIN
FOR emp_rec IN c_emp LOOP
l_data.extend;
l_data(l_data.count) := emp_rec.ename;
END LOOP;
RETURN l_data;
END;
In Java
public static void main( ) {
OracleCallableStatement stmt =(OracleCallableStatement)conn.prepareCall
                ( "begin ? := getEMpArray; end;" );
    // The name we use below, EMPARRAY, has to match the name of the
    // type defined in the PL/SQL Stored Function
    stmt.registerOutParameter( 1, OracleTypes.ARRAY,"EMPARRAY" );
    stmt.executeUpdate();
    // Get the ARRAY object and print the meta data assosiated with it
    ARRAY simpleArray = stmt.getARRAY(1);
    System.out.println("Array is of type " + simpleArray.getSQLTypeName());
    System.out.println("Array element is of type code "+simpleArray.getBaseType());

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,

I would want to use Oracle provided (Oracle Extensions) API to pass arrays to PL/SQL
procedure from Java. I am using weblogic connection pool, but the 'createDescriptor'
method donot allow Pooled connection. So I have taken Physical Connection by casting
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.

I want your opinion in this, so that I will be confident in using this feature
in our application.
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.
Thanks

BO v5.1 - creating a report from an oracle stored procedure

Post Author: newrochelle

hi to all,
im using BO 5.1 and i need to create a document from an oracle stored procedure that have only one IN parameter and ten OUT parameters.
Creating the new report I selected the database connection then I choose the stored procedure name from the list, I inserted the value for the IN parameter and finally I click on Run button.
I got the following error message:
ORA-06550: line 1, column 38: :PLS-00103: Encountered the symbol
"," when expecting one of the following: : : ( - + case mod
new not null others <an identifier> : <a double-quoted
delimited-identifier> <a bind variable> avg : count current
exists max min prior sql stddev sum variance : execute forall
merge time timestamp interval date : <a string literal with
character set specification> : <a number> <a single-quoted SQL
string> pipe : <an alternatively-quoted string literal with
character set specification> : <an alternatively-q :-6550
it seems to be caused by the OUT parameters!
i leaved them without any value.
it's the first time that I used a stored procedure to create a BO report, but I think the OUT parameters are needed to do that, otherwise what data will be presented in the report???
can you help me?
please answear me ASAP.
Thank's in advance
Regards
Andrea
