Using an SQL table in a Java program?

Hello, I am quite new to programming and would like to know if it is possible to have an SQL database as a backend, linked to my Java program?
If it is pobbible, could someone give me breif overview of the procedure.
Much appriciated.
Thankyou

Yes, use JDBC:

How to display a oracle table from a java program?

How to display a oracle table from a java program.
Hello friends, I have written a Java program, using oracle 10g as backend.
I want to display a oracle table as output. Im not getting how to display oracle table as a output table.. Pls help me
Thank you

jayanthds, you're not going to get a satisfactory
answer to this here. it's too big a task to justbe
quickly outlined in a forum - the reply "all youneed
to do is to query you table and return it asJTable"
is worthless, for example, since the solution to
any problem can be distilled to such a
soundbite, if need be. doesn't make the solutionany
simpler
essentially you're asking "how do I write adatabase
application?". all you'll get is snippets of code
that, when fitted together, will eventually helpyou
do this, but you'll spend days and days comingback
saying "right, I've done that, now what?" until
either you or the forum gets frustrated with the
whole affair and the process stops
there are entire books written about this subject,
and countless tutorials and guides on theinternet.
you're better off going down that routehehehe.well, it's true! I used to have a manager that would outline the solution to a problem in a few lines of pseudocode, and then firmly believe that the actual solution would be just as brief and simple. shame his pseudocode included such lofty abstractions as "reformat all data"

How to use PL/SQL table

Hi all,
can you guys suggest me how can I use pl/sql tables for the below query to incresing the performance.
DECLARE
    TYPE cur_typ IS REF CURSOR;
    c           cur_typ;
    total_val varchar2(1000);
    sql_stmt varchar2(1000);
    freeform_name NUMBER;
    freeform_id NUMBER;
    imgname_rec EMC_FTW_PREVA.EMC_Image_C_Mungo%rowtype;
    imgval_rec EMC_FTW_PREVA.EMC_Content_C_Mungo%rowtype;
    CURSOR imgname_cur IS
        select * from EMC_FTW_PREVA.EMC_Image_C_Mungo
        where cs_ownerid in (
                    select id from EMC_FTW_PREVA.EMC_Image_C
                    where updateddate > '01-JUN-13'
                    and path is not null
                    and createddate != updateddate)
        and cs_attrid = (select id from EMC_FTW_PREVA.EMC_ATTRIBUTE where name = 'Image_Upload');
BEGIN
    OPEN imgname_cur;
    LOOP
      FETCH imgname_cur INTO imgname_rec;
      EXIT WHEN imgname_cur%NOTFOUND;
      total_val := 'EMC_Image_C_' || imgname_rec.cs_ownerid;
      sql_stmt := 'SELECT instr(textvalue,''' || total_val || '''), cs_ownerid FROM EMC_FTW_PREVA.EMC_Content_C_Mungo a Where cs_attrid = (select id from EMC_FTW_PREVA.EMC_ATTRIBUTE where name = ' || '''' || 'Body_freeform' || '''' || ')';
        OPEN c FOR sql_stmt;
        LOOP
          FETCH c INTO freeform_id,freeform_name;
          EXIT WHEN c%NOTFOUND;
                                  IF freeform_id > 0 THEN
            dbms_output.put_line (imgname_rec.cs_ownerid || ',' || total_val || ',' || freeform_id || ',' || freeform_name);
                                  END IF;
        END LOOP;
        CLOSE c;
   END LOOP;
   CLOSE imgname_cur;
END;
Thanks in Advance.

can you guys suggest me how can I use pl/sql tables for the below query to incresing the performance.
There would be absolutely no point at all in improving the performance of code that has NO benefit.
The only result of executing that code is to possibly produce some lines of output AFTER the entire procedure if finished:
dbms_output.put_line (imgname_rec.cs_ownerid || ',' || total_val || ',' || freeform_id || ',' || freeform_name);
So first you need to explain:
1. what PROBLEM you are trying to solve?
2. why you are trying to use PL/SQL code to solve it.
3. why are you using 'slow by slow' (row by row) processing and then, for each row, opening a new cursor to query more data?
You should be using a single query rather than two nested cursors. But that begs the question of what the code is even supposed to be doing since the only output is going to a memory buffer.

Huge memory leaks in using PL/SQL tables and collections

I have faced a very interesting problem recently.
I use PL/SQL tables ( Type TTab is table of ... index by binary_integer; ) and collections ( Type TTab is table of ...; ) in my packages very widely. And have noticed avery strange thing Oracle does. It seems to me that there are memory leaks in PGA when I use PL/SQL tables or collections. Let me a little example.
CREATE OR REPLACE PACKAGE rds_mdt_test IS
TYPE TNumberList IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
PROCEDURE test_plsql_table(cnt INTEGER);
END rds_mdt_test;
CREATE OR REPLACE PACKAGE BODY rds_mdt_test IS
PROCEDURE test_plsql_table(cnt INTEGER) IS
x TNumberList;
BEGIN
FOR indx IN 1 .. cnt LOOP
x(indx) := indx;
END LOOP;
END;
END rds_mdt_test;
I run the following test code:
BEGIN
rds_mdt_test.test_plsql_table (1000000);
END;
and see that my session uses about 40M in PGA.
If I repeat this example in the same session creating the PL/SQL table of smaller size, for instance:
BEGIN
rds_mdt_test.test_plsql_table (1);
END;
I see again that the size of used memory in PGA by my session was not decreased and still be the same.
The same result I get if I use not PL/SQL tables, but collections or varrays.
I have tried some techniques to make Oracle to free the memory, for instance to rewrite my procedure in the following ways:
PROCEDURE test_plsql_table(cnt INTEGER) IS
x TNumberList;
BEGIN
FOR indx IN 1 .. cnt LOOP
x(indx) := indx;
END LOOP;
x.DELETE;
END;
or
PROCEDURE test_plsql_table(cnt INTEGER) IS
x TNumberList;
BEGIN
FOR indx IN 1 .. cnt LOOP
x(indx) := indx;
END LOOP;
FOR indx in 1 .. cnt LOOP
x.DELETE(indx);
END LOOP;
END;
or
PROCEDURE test_plsql_table(cnt INTEGER) IS
x TNumberList;
empty TNumberList;
BEGIN
FOR indx IN 1 .. cnt LOOP
x(indx) := indx;
END LOOP;
x := empty;
END;
and so on, but result was the same.
This is a huge problem for me as I have to manipulate collections and PL/SQL tables of very big size (from dozens of thousand of rows to millions or rows) and just a few sessions running my procedure may cause server's fall due to memory lack.
I can not understand what Oracle reseveres such much memory for (I use local variables) -- is it a bug or a feature?
I will be appreciated for any help.
I use Oracle9.2.0.1.0 server under Windows2000.
Thank you in advance.
Dmitriy.

Thank you, William!
Your advice about using DBMS_SESSION.FREE_UNUSED_USER_MEMORY was very useful. Indeed it is the tool I was looking for.
Now I write my code like this
declare
type TTab is table of ... index binary_integer;
res TTab;
empty_tab TTab;
begin
res(1) := ...;
res := empty_tab;
DBMS_SESSION.FREE_UNUSED_USER_MEMORY;
end;
I use construction "res := empty_tab;" to mark all memory allocated to PL/SQL table as unused according to Tom Kyte's advices. And I could live a hapy life if everything were so easy. Unfortunately, some tests I have done showed that there are some troubles in cleaning complex nested PL/SQL tables indexed by VARCHAR2 which I use in my current project.
Let me another example.
CREATE OR REPLACE PACKAGE rds_mdt_test IS
TYPE TTab0 IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
TYPE TRec1 IS RECORD(
NAME VARCHAR2(4000),
rows TTab0);
TYPE TTab1 IS TABLE OF TRec1 INDEX BY BINARY_INTEGER;
TYPE TRec2 IS RECORD(
NAME VARCHAR2(4000),
rows TTab1);
TYPE TTab2 IS TABLE OF TRec2 INDEX BY BINARY_INTEGER;
TYPE TStrTab IS TABLE OF NUMBER INDEX BY VARCHAR2(256);
PROCEDURE test_plsql_table(cnt INTEGER);
PROCEDURE test_str_tab(cnt INTEGER);
x TTab2;
empty_tab2 TTab2;
empty_tab1 TTab1;
empty_tab0 TTab0;
str_tab TStrTab;
empty_str_tab TStrTab;
END rds_mdt_test;
CREATE OR REPLACE PACKAGE BODY rds_mdt_test IS
PROCEDURE test_plsql_table(cnt INTEGER) IS
BEGIN
FOR indx1 IN 1 .. cnt LOOP
FOR indx2 IN 1 .. cnt LOOP
FOR indx3 IN 1 .. cnt LOOP
x(indx1) .rows(indx2) .rows(indx3) := indx1;
END LOOP;
END LOOP;
END LOOP;
x := empty_tab2;
dbms_session.free_unused_user_memory;
END;
PROCEDURE test_str_tab(cnt INTEGER) IS
BEGIN
FOR indx IN 1 .. cnt LOOP
str_tab(indx) := indx;
END LOOP;
str_tab := empty_str_tab;
dbms_session.free_unused_user_memory;
END;
END rds_mdt_test;
1. Running the script
BEGIN
rds_mdt_test.test_plsql_table ( 100 );
END;
I see that usage of PGA memory in my session is close to zero. So, I can judge that nested PL/SQL table indexed by BINARY_INTEGER and the memory allocated to it were cleaned successfully.
2. Running the script
BEGIN
rds_mdt_test.test_str_tab ( 1000000 );
END;
I can see that plain PL/SQL table indexed by VARCHAR2 and memory allocated to it were cleaned also.
3. Changing the package's type
TYPE TTab2 IS TABLE OF TRec2 INDEX BY VARCHAR2(256);
and running the script
BEGIN
rds_mdt_test.test_plsql_table ( 100 );
END;
I see that my session uses about 62M in PGA. If I run this script twice, the memory usage is doubled and so on.
The same result I get if I rewrite not highest, but middle PL/SQL type:
TYPE TTab1 IS TABLE OF TRec1 INDEX BY VARCHAR2(256);
And only if I change the third, most nested type:
TYPE TTab0 IS TABLE OF NUMBER INDEX BY VARCHAR2(256);
I get the desired result -- all memory was returned to OS.
So, as far as I can judge, in some cases Oracle does not clean complex PL/SQL tables indexed by VARCHAR2.
Is it true or not? Perhaps there are some features in using such way indexed tables?

Using the Insert statement in a Java program without hardcoding the data

hello.
this is james mcfadden. i have developed a program called Demo.java, which is used with another program called QueryTableModel.java (a program that allows data to be viewed in a JTable). The Demo.java program displays a menu, connects to a database, allows the user to add data into the database and allows the user to view data that is already in the database. I have a problem with the Demo.java program. I have hardcoded the Insert statement in it. How do you use the Insert statement to put data into a database without hardcoding the data?

How do i use an import statement in a java program

I need to write a java program which will connect to the Database but i need to do an import like in DB2 which will load data to the table.
How do i execute that import statement

Are you saying that you need to add rows to a table in DB2 via a Java program? If so, you need to look at the JDBC API, (available on this site along with a bunch of tutorials). If not, post again with a clearer description of your problem.

But we have to use the PL/SQL table as per our design standards.
We are implementing the population logic of the PL/SQL table in the database as a
package function. We are then accessing the PL/SQL table in Forms to populate the record group.It is curious that you would have such a unique requirement -- something that might make forms run a tiny bit faster -- yet you are using an ancient version of Forms.
Also the "NO DATA FOUND" error is not raised everytime the PL/SQL table is accessed.
What could be the reason for this erratic behaviour?I wonder if there may be a bug in SQL Net in the Oracle-to-Forms communication where PL/SQL tables are passed as out parameters. I know there is one in Web Forms 6 (6.0.8.19.1) when passing a pl/sql table from the form to Oracle -- I had to write the pl/sql table to a database table to get my process to work.

To generate a wsdl using JAX-WS in JBOSS with java program but without EJB

Hi,
I am using JAX-WS to generate webservices using JBOSS application server by writing a java program.
My sample java program includes :which takes an i/p name as string and displays out put as "Hello name",with the use of annotations.And,also have written web.xml for it.If I start JBOSS without adding project to it,it is starting.BUt If I add project to it the server is not publishing.Its getting like:"publishing JBOSS 4.2.2....:waiting for virtual machine to exit".
I have followed the link:*http://www.javabeat.net/articles/2007/10/creating-webservice-using-jboss-and-eclipse/3*
to do this,where in it was given that by means of auto build process of eclipse IDE war file generates in default jboss folder.But which is not happening,so that,am unable to generate wsdl file..
Can any body help me?
1) why jboss is not publishing after adding project to it?
2) why war file is not generating in the default jboss folder?
Regards....

Yeah sure!!
Overall picture: I wish to expose my OSB services to the third parties using OCSG. For that I've created the Communication services corresponding to each OSB service.
Problem: Integration with the OSB.
At the OSB side I've got JMS queues which interacts with other existing systems in my SOA enviornment. But I'm not getting how to get the OCSG application- triggered request messages in that queue? Please help.
Also I've read about the SOA facades for integration with OSB.Which of the two approaches you will suggest?

Accessing Sql Server from AS400 Java program

Hi everybody,
I am trying to access Sql Server from an AS400 Java program. I have tried various Sql Server JDBC drivers including the Microsoft one but no luck yet. When i try to compile my Java program (with driver file in the classpath) it gives some errors on the driver jar file and also it throws out lots of unreadable text characters. This gave me a feeling that probably its a character coding issue with the jar file, so i tried ftp the file in binary mode as well as copying through the Operations Navigator. But still compilation is giving the same kind of errors.
Do I need to have some special JDBC Drivers compiled for AS400 specifically. My understanding was that Java is platform independent so any JDBC Type 4 driver will work.
We are running Java 1.3 on the AS400. Any help on this issue would be great.
Thanks
Inder

Thanks for the help. I am writing a Java program after a long time that's why was making that mistake. Now the program gets compiled correctly but on running the program i am getting the following error message:
java 001-0070: Exception JVAB544 not expected
/myjava/test/msbase.jar: 001-0050 Syntax error on Line 1: token ')' not expected
/myjava/test/msutil.jar: 001-0050 Syntax error on Line 1: token ')' not expected
/myjava/test/mssqlserver.jar: 001-0050 Syntax error on Line 1: token ')' not expected
I have no idea what is this error about. Though the same driver files don't give any error when running on a Windows machine.
Thanks

Design question on using PL/SQL table

Hi I am doing some data extract and write it to a file. The main table is over 100 million rows. It is is partition by ID. So I am thinking of paralleling it.
We are on 10g so we can not use the dbms_parallel.
I would like to use dbms_scheduler or the table function like the Oracle MapReduce example
However, I am not quite sure how to control the degree of parallism using the Oracle MapReduce
Moreover the company has the own unix scheduler and I am 90% sure the old-timer would shoot down my idea and urge to use the in-house built scheduler to this kind of parallel job.
So I would create a procedure that takes a list of ID and then run the extract, write out the file
and this procedure will call by sqlplus on unix.
Once all the threads are done, then the unix script will combine all the files produced into one file.
So my question is how to go about passing IN/OUT of the PL/SQL table and how I can put that PL/SQL table inside of a cursor
Can someone kind enough to give me some example/sample
-Thanks so much

Does order of records in resultant file matter?
So my question is how to go about passing IN/OUT of the PL/SQL table and how I can put that PL/SQL table inside of a cursor
Pass from where to where?
Why PL/SQL table?
Realize that SQLPLUS knows nothing about PL/SQL table
Can someone kind enough to give me some example/sampleI could but then we'd both look unprofessional.

Use PL/SQL Table values as a comma delimited list in a in (...) clause

Hi,
One my procedure's parameters is a PL/SQL table of id's (NUMBER) that the GUI sends it, based on the user's selections.
Now, I want to use the table's values in my select's where clause to return only the correct records.
However,
select ......
from ....
where id in (i_array_ids)
doesn't work of course, and my attempts of transfering the ids to a comma delimited list of numbers (as opposed to a lenghty varchar2 string) that could work between the ( ) have all failed.
Thanks

And here's an example I gave with some more up-to-date syntax than in that old AskTom thread:

OLIST will contain the report output that you have executed but you need to tweak this internal table so that it can be used for further processing.The current example will get you MB51 output into OLIST,so change the program name to your program name at the SUBMIT statement and then try.

Can LabVIEW variables be used like those found in a Java program?

I created a decoding program in Java that reads in a certain number, or code, and returns the decoded version of that number.
I tried initially to create this program inside of LabVIEW itself but was hindered by my lack of familiarity and knowledge of what LabVIEW can and can't do and how to approach the problem in LabVIEW.
My stumbling blocks in LabVIEW seem to be the arrays and working the variables. I'm probably approaching this completely wrong, more than likely because I'm trying to think in Java rather than LabVIEW.
Any help that can be given is most appreciated. Also I have attached a text document with my Java code in it. It's not perfect but it works.
If I need to clarify anything just ask.
Once again thanks for any help in advanced.
Solved!

In LabVIEW the wire is the variable. The way you pass parameters to functions (subvis) is with a wire through the connector pane. Same for returning results.
Forget that local variables exist! A lot of new programmers that come from a text based programming background discover the LabVIEW local and global variables way too early. Like duct tape they can be useful. But it is possible to write huge complex applications without touching them. And the code is much simpler than programs of less complexity that make extensive use of locals and globals.
Since you are new to LabVIEW you can become a very good programmer if you keep the following in mind. It is a little confusing but "local variables" and "global variables" are not really variables in labVIEW like they are in Java. The wires are the variables. Those rectangle things you create from controls or indicators are more like a function for that control or indicator. They can not exist without an owning control or indicator. It is unfortunate that they are called variables but they are a relic of the stone ages when code was carved into cave walls.

*How can we use the internal table in module pool programming? Clarify plz*

If we creating a screen using the table having four fields(for e.g.). The screen has the functions of display, modify, delete, save, exit etc for the fields. The front-end of the screen having I/O fields of the table using internal table. How can we declare the internal table in the screen?

HI,
Create one WA for your Internal table and then map it to your fields.
For Example,
Data : begin of wa,
          name(10),
          age type i,
           end of wa.
data : it like table of wa with header line.
Then in screen create input fields with the name, age and ***.
Then the user entered values are stored in name age and ***.
then you can manipulate with that values using wa.
Thanks.
