Passing Nested table or Vararray from Java to Oracle store procedure

I have some CSV file with arround 50,000 lines. I need to pass read those lines from Java to Oracle as a collection object.
Pro & cons of both the options.
Need some suggestions...

Lokanath

Hi,
why not using External tables. Then you can in Oracle work it out by just using it as a normal table with all the profits.

Passing a table-field value in Crystal to a Store Procedure in SQL Server

I have been checking all over the interenet via searches and although some seem to come close to this, its still not what I want.
Essentially I need to pass value from Table-Field record (for each record read/selected) via a paramete to a Stored Procedure(SP) in SQL Server 2205/2008. I do NOT want to be prompted for a value for this parameter each time the report is run, simple pass the value in which will be used along with other select criteria to bring back one value for the report to use in a calcuation per record.
The value of the parameter is a date, but I understand it would be better to pass it in as a varchar(8) - 'YYYYMMDD' - and then reconvert it inside the SP, as follows:
In Crystal Reports 2008 SP3, I have a formula defined as,
trans_date = ToText ({F1ARS_STMT_WS_TRAN.TRANS_DATEI}, 'YYYYMMDD')
and essential just want to pass this to the SP below ... i.e. trans_date ---> @strTransDate
I then link the key fields [EXCH_RATE_TABLE_NAME] and [TRANS_CCY_CODE] to other tables in the Database Expert, and put [EXCH_RATE_AMT] on the report and use it to calculate what I want.
This works fine when the prompt comes up and I put in a proper date, but I don't what it to prompt, but simple pass the F1ARS_STMT_WS_TRAN.TRANS_DATEI in via the fornula/parameter and let teh SQL do the rest for each record selected..
CREATE PROCEDURE [dbo].sp_GET_EXCH_RATE_AMT (@strTransDate varchar(8))     --use format 'YYYYMMDD' to represent the date as a string.
     -- Add the parameters for the stored procedure here
     -- @TransDate datetime = now
AS
     declare @TransDate datetime
     set @TransDate = CONVERT(DATETIME, @strTransDate, 112)
BEGIN
     -- SET NOCOUNT ON added to prevent extra result sets from
     -- interfering with SELECT statements.
     SET NOCOUNT ON;
    -- Insert statements for procedure here
SELECT [EXCH_RATE_TABLE_NAME], [TRANS_CCY_CODE], [EXCH_RATE_AMT]
FROM [F1CCY_EXCH_RATE]
WHERE [MAJOR_CCY_CODE] = 'BBD'
AND   [START_DATEI] =
     SELECT MAX([START_DATEI])
     FROM [F1CCY_EXCH_RATE]
     WHERE [MAJOR_CCY_CODE] = 'BBD'
     AND   [START_DATEI] <= @TransDate
END
GO
GRANT EXECUTE ON sp_GET_EXCH_RATE_AMT TO PUBLIC
GO
Thanks for any help. Can't tell the headache this has caused my both literally and figuratively.

Hello,
I moved your post to the Report Design forum. Lots of SQL help in here...
I believe the problem is due to you using a Parameterized Stored Procedure. The first thing CR has to do is connect to your DB source which requires the date parameter before it can run the query to add the date filter, it's the SP that is prompting for the parameter. Therefore the report has not run so it can't get the field value from the report until you fill in the info for the SP. Catch 22 problem.... Which came first, the Chicken or the Parameter....
The report will work as you have noted but I don't know of anyway to refresh unless parameter is filled in again....
Jason has a lot of great solutions when it comes to these dilemmas, Possibly using a Command Object may help but I believe you will still run into the same issue....
Only way I can think of is to not use a parameter in the SP and let CR do the filtering client side. Of course this means all data is coming back to the client PC as you are likely trying to find a work around for.
Thank you
Don

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.

Calling Oracle store procedure from Crystal 11 command

I need to call Oracle store procedure from Crystal Command. The Store proc has ref cursor. Is it possible. Can you post few examples?
Also, is it possible to have multiple sql statements in a Crystal Command, when working with Oracle 10g?
It is working for SQL server.

Please re-post if this is still an issue to the Data Connectivity - Crystal Reports Forum or purchase a case and have a dedicated support engineer work with you directly.

Passing an array as parameter from java (java controls) to stored procedure

Accessing XI Tables (ABAP Stack) from Java code

Hi,
IS it possible to access tables like SXMSPMAST, SXMSPEMAS directly from Java code without the use of any RFC or BAPI in between?
Cheers,
Earlence

I think it is technically possible, as you can get access to the JDBC Connector service using J2EE's JNDI feature ... Then you can use the internal DB datasource to read data from tables (read ONLY, cuz I'm not sure it is a good idea to update data "outside" the box, and reading can also have potiential perf or stability issue) ... Some (better) methods can also exist !

Passing array of objects from java to oracle.

Hi,
We have the following structure in oracle.
We have a nested table type of varchar2(50).
type var_tab is table of varchar2(50);
We have one object type with one member as varchar2 and another one as var_tab type.
type attribute_obj is object(
attrib_name varchar2(100)
,attrib_val var_tab
Then we have table type of that object type,
type table_tab is table of attribute_obj;
Then we have one object type with one member as varchar2,another member as integer and another one as table_tab type.
type prod_obj is object(
pr_name varchar2(100), tb_flag integer
,pr_attrib table_tab
Then we have table type of this object type,
type prod_tab as table of prod_obj;
So, the total structure is something like this;
'OS','OS_NAME', 'Windows'
'Linux'
'UNIX'
'OS_VERSION','XP'
'RED HAT'
'SOLARIS'
so, basically we have
x prod_tab:=prod_tab();
x(3):=prod_obj('OS',0,table_tab(attribute_obj('OS_NAME',var_tab('Windows','Linux','UNIX')),attribute_obj('OS_VERSION','XP','RED HAT','SOLARIS'))));
And this how we call the procedure ---
all_prod_comb_pkg.sp_main(x)
The procedure deifinition is -
procedure sp_main ( p_prod_arr prod_tab);
Please suggest a way so that we can implement the same structure in Java and then call the procedure using that array of objects.
regards,
Dipankar.

Dipankar,
There's a separate example of how to map Oracle OBJECTs to JDBC STRUCTs.
Study that one and combine the two. Not difficult (in my opinion :-)
Or search the JDBC forum for the words "STRUCT" and "ARRAY".
(What, you want me to do your coding for you?)
Good Luck,
Avi.

Pass arrays from Java to PL/SQL procedure.

Hi All,

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.

Passing parameter to VB Script from Java file

I have a jhtml(read java) page which is trying to create a virtual directory in IIS. The servlet container run on IIS. I have a VB Script file (.vbs) which creates the virtual directory. Now the vbs file needs a parameter to create a new directory every time and the directory name should be the parameter name. I am able to run the vbs from java but the parameter passing doesn't work.
String acctname = "test";
String path = "d:/ScriptTool/CreateAccountWebIIS.vbs";
String fullpath = path+" "+ "/c:"+acctname;
System.out.println("path = "+fullpath);
Process process1;
Runtime userRuntime = Runtime.getRuntime();
try
process1 = userRuntime.exec("wscript.exe " + fullpath);
discussed options
1) convert vbs to exe
2) use batch file

If you're creating a string that is going to be used as a file name by a Windows program on a Windows command line, then you have to use the backslash to separate directories in the path.String path = "d:\\ScriptTool\\CreateAccountWebIIS.vbs";Forward slashes are okay (actually, preferred) in Java code for use by Java classes but once you hand it over to Windows you do need to follow the Windows rules.

Reports from Java and Oracle database

Hi
I need to generate couple of reports from my application, with Java as front end and oracle 11.2.0.3.0. database . Reports are having very simple select statements, using the criteria users enter from GUI. we don't need to execute a direct select statement from Java, with the where clauses . I did some research and found out about Pipelined functions. I tested for a small set of records and it worked fine. Will this work for large data set? any drawbacks of using this method? Any other methods for this requirement?
Thanks in advance
JP

Pipeline table functions do not sound like the appropriate approach. It is designed to primarily deal with data transformations. Using it as a rendering engine for report writing? There are fundamental problems with such an approach.
As Dave and Andre commented - the CORRECT means for PL/SQL to pass "data" to Java (or other client languages) is via reference cursors (pointers that the client can use for referencing SQL cursor programs on the server). And Java as a report writer does not really compare with the ease and flexibility that Oracle Apex (Application Express) provides as a reporting framework.

It appears you are trying to store java objects (types) in a database rather than raw data (string, int, date types) that the object contains. If so, I don't think that ever really caught on. Most programmers store the raw data, then pull it out and populate a class. The problem with storing the object is that new versions of classes come out and your old version is stored in the database. If you just store the data, you don't have to worry about what version is in the database. You can populate the new version of the class with the same data.
Also, others can use sql to query your data and use it for their own use independent of what you intended it for. I think most people use the (browser) based utility that comes with the database to create the tables, normalize them, set up primary keys, set up foreign keys, etc rather then run an sql statement as you did above.

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.

How do you send a date from java to a stored procedure

I'm trying to pass a date to a stored procedure. Does anybody
have an example of how to do this.
I want to send a month-day-year 01/01/1999 to oracle to be

Wow. You got me there. All of the pdfs that i have, when i tap that icon, open a drop down window with the choices of e mail or print. I wonder if the particular pdf you are working on is somehow protected? Try a different pdf and see if the box recats the same way. You might also do a full shut down and just try again. Make sure there is not an old instance of i books, or some other pdf editor sitting in the task bar, by doblue clicking the home button, and shutting down any open apps.

Invoking bpel process from java in oracle soa/bpm 11g

Hi,
We have some java code to invoke bpel process in oracle BPM 10g following the instructions in http://download-east.oracle.com/docs/cd/B14099_19/integrate.1012/b14448/invoke.htm.
Basically the steps are:
1) get a Locator (com.oracle.bpel.client.Locator)
2) get IDeliveryService (com.oracle.bpel.client.delivery.IDeliveryService) reference from locator
3) call IDeliveryService method request or post with input message and get the response back.
Recently we want to migrated from oracle bpm 10g to oracle soa/bpm 11g. But I can not find the similar API in 11g. It seems now some adapter/binding need to be added in exposed service lane in soa composite view, for example, ADF-BC, direct binding etc, in order to allow java to invoke a bpel process. Here are two very useful links from Edwin about the detail how this is implemented.
http://biemond.blogspot.com/2009/11/invoking-soa-suite-11g-service-from.html
http://biemond.blogspot.com/2009/11/calling-soa-suite-direct-binding.html?showComment=1285198033913#comment-c1055322845511794252
My question is:
1) what are the choices and the official/best way to invoke a bpel process in oracle soa/bpm 11g from java?
2) does user need to add an adapter/binding in exposed service lane in order to let the bpel service be called in java?
3) what is the real difference between a bpm application and soa application in 11g?
I will really appreciate any expert's opinion.
Thanks,
Bin

Thanks for your reply and confirmation, really appreciate it.
Yes, I found the difference of the invoking process API and was able to invoke bpel process using direct and ADF-BC binding by following Edwin's blog. But I have not found any official reference to compare this API difference between 10g and 11g ( I will mark this question as answered if anyone can find an official source from oracle, need to prove it to the team). The API to work with human task workflow seems pretty much the same between 10g and 11g.

How can I pass a BLOB parameter 32K from VB to a stored procedure?

I am using Visual Basic 6 and the Oracle database 10g to call stored procedures. I am passing a XML input parameter to this stored proc. This variable has been defined as BLOB in stored proc and as XMLType in the table to which it finally gets stored through procedure.
But there seems to be a limit to the size of a parameter you can pass in. This seems to be 32K!!! It works fine as long as my input is < 32k but once it becomes > 32k, Oracle gives the following error:-
"ORA-01460: unimplemented or unreasonable conversion requested"
I searched on net and found lots of examples for a workaround with .Net (using OracleLob). For Vb6, the only examples I found were using AppendChunk method etc through a loop, where each call will insert 32k chunk. But, that would mean lots of calls to stored proc, as we need to do this for thousands of files and each file of size > 100k.. So, this method would not be acceptable.
Can someone please help me with this.

Mofizur,
You can achieve the same using Session variable.
If u are not executing the VO after PR. Then you will be able to get the same value as u are using in PR
String transactionId = (String) vo_trans.first().getAttribute("Getnexttrans");
Note - You have a few of the threads left open, mark it as answered if solved.

Gyan
