Struts page control - stored procedure and refresh

Hi Guys,
I have a struts page with a read-only form that gets data from the database through a view - the contents of this table can change dynamically. There is a button on this page that allows me to refresh the page and see the current contents of the table.
I also have another button on this page that calls a stored procedure which updates the table. However, when I click this, I also want the page to refresh so that I can see the results of the procedure's update - the page does refresh but displays the content of the table BEFORE the procedure ran.
I have had a look at a javascript solution and it doesn't really fly.
I think that what I need is a hook in the class that calls the stored procedure that also selects from the view. I think that, when the page refreshes after the procedure call, the new view contents will be displayed.
Does anone have an idea as to how I go about this?
TIA
Steve

"How to call PL/SQL Stored procedures" if you search the board will describe how to call a stored proc (or function) and get the result set into a scrollable jtable that is SIMILAR to the DAC gridcontrol.
That isn't exactly what you asked... it isn't using the DAC gridcontrol.
I'd be interested in seeing how someone did the latter.
Hopefully the JDEV team are well acquanted with how folks develope using Reports and Forms and can apply the capabilities there ( like getting results from stored procs into via toolset for programmer use ) to the DAC controls and rollover such existing capabilities into Jdev in the future.

How to create a stored procedure and use it in Crystal reports

Hi All,
Can anyone explain me how to create a stored procedure and use that stored procedure in Crystal reports. As I have few doubts in this process, It would be great if you can explain me with a small stored proc example.
Thanks in advance.

If you are using MSSQL SERVER then try creating a stored procedure like this
create proc Name
select * from Table
by executing this in sql query analyzer will create a stored procedure that returns all the data from Table
here is the syntax to create SP
Syntax
CREATE PROC [ EDURE ] procedure_name [ ; number ]
    [ { @parameter data_type }
        [ VARYING ] [ = default ] [ OUTPUT ]
    ] [ ,...n ]
[ WITH
    { RECOMPILE | ENCRYPTION | RECOMPILE , ENCRYPTION } ]
[ FOR REPLICATION ]
AS sql_statement [ ...n ]
Now Create new report and create new connection to your database and select stored procedure and add it to the report that shows all the columns and you can place the required fields in the report and refresh the report.

Oracle stored Procedure and Packages in CR4E

Hi,
I want to use Stored Procedure in CR4E. I don't know how to use Stored Procedures and packages in Crystal Reports for Eclipse. In the data source explorer I can only see the Tables, Views and Stored Procedures but not packages from my Schema and when I can only drag & drop the Tables and Views into the Field Explorer, I can't drag & Drop the Stored Procedures.
I managed to attached the stored procedure from CR studio. I opened the report in CR4E and I can see the stored procedure and can preview the data. When I try to run the report and override the datasource, it throws oracle error saying "ORA-01008: Not all variables bound". When I tried to use the option
DBOptions._doNotVerifyDB
while replacing connection I get the this error

Please advice if Stored procedures and packages are supported in CR4E ?

Hi, Jack76,
According to the [CR4E Release Notes|http://help.sap.com/businessobject/product_guides/cr4E/en/cr4e_relnotes_en.pdf] (available from the [CR4E Download page|http://www.businessobjects.com/campaigns/forms/downloads/crystal/eclipse/datasave.asp]), stored procedures are supported, as long as they don't use parameters that need null values.
I don't see any references to packages.

I just got the new itunes and I can open itunes and see my music but whenI try and go to the itunes store it just loads to a white page. I try and refresh and go to the home page and nothing happens. I can sign into my account and the tabs for the itunes store pop up like they normally would when browsing the itunes store but when I click on one of them, it is a blank page. Is there a setting I need to change? Does it just take an extremely long time to load? Please help!!

Bucktr09:
I'm having the exact same problem. I upgraded to the newest version of iTunes on my iMac and ever since I did the store is a blank white screen. I can get my library content but the store is a no go. Is there any one out there with a solution?

Stored procedure and peoplecode in app engine

Hey all,
i want to call a stored procedure in peoplecode using sqlexec. i guess the following syntax is correct.
sqlexec("exec sp_name");
my question is
will the peoplecode wait until the stored procedure completes?
or
will it just send the command to database to execute the stored procedure and continue executing the next statements after the sql exec.
Please let me know if i am not explain better and need to give an example.
Please help me.
thank you.

"...will the peoplecode wait until the stored procedure completes"
Yes.

Java stored procedures and triggers in lite

Hi
We are using java stored procedures and java triggers in our application for oracle lite database 5.1.
We would like to know whether these procedures and triggers are uploaded or associated with tables or not because triggers are not being fired for the tables.
The question is - how to find the uploaded procedures and triggers in system tables.
We dont find any tables like (all_objects, user_objects) for this in oracle lite system catalogs given in the documentation.
thanks in advance
yugandhar

I don't have much experience with Lite, but I'm running 9i Personal Edition. Any information about triggers can be found in the "ALL_TRIGGERS" view. You will want to filter out any rows where OWNER = 'SYS' unless you created your triggers as SYS. As for procedures and functions, you can see what you have created in the "ALL_OBJECTS" view where OBJECT_TYPE = 'PROCEDURE' or 'FUNCTION', once again filtering out rows where OWNER = 'SYS'. To see the code of any procedure or function, select substr(text,1,80) from ALL_SOURCE where NAME = 'function name' ORDER BY LINE.
Hope this helps!

Java stored procedures and referencing classes

We are referencing to some classes/libraries which are not present in the database. In normal java world, you specify the libraries/classes needed to run your piece of code in the CLASSPATH and that forms part of your complete code.
Can java stored procedures in the database refer to libraries or class files it requires on the file system rather than the database? Is it possible to make this happen?
Thanks

pshiva,
Posting the same question to multiple forums usually doesn't increase your chances of getting an answer, and it just frustrates those wishing to answer you with the result being that any future questions you post may have less chance of being answered -- because of your uncourteous, initial behaviour.
I have answered your other thread:
java stored procedures and referencing classes
In my opinion, that forum (the Database JVM forum) is the most appropriate for your question.
Good Luck,
Avi.

Mark this question ANSWERED and repost the question in the other forum
Before you post review the Oracle Database Java Developer's Guide - it shows how to create Java stored procedures and has example code
http://docs.oracle.com/cd/B28359_01/java.111/b31225/chfive.htm
And in the new post don't just say "I tried but it didn't work". You need to post the code that you tried and what you mean by "didn't work".
If you got any exceptions or errors you need to post a copy of the exact message or error that you are getting.

Can i use Stored procedures and triggers with SDK

hi all
How to use the stored procedure and Triggers with SDK, can i get a sample code
Regards

Hi, Salah.
Use "Exec" in your query to run procedures.
SAPbobsCOM.Recordset oRS;
oRS = (SAPbobsCOM.Recordset)pCmp.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset);
oRS.DoQuery ("EXEC YourStoredProcName");
Triggers are not supported in SDK.

Triggers, Stored Procedures and Java

Hi all.
I started developing some useful (at least for me) Java Package, and I'm wondering if I'm doing the right thing.
Let's say that I have a trigger that calls a Stored Procedure that calls a Java Package.
Let's say that the Java Package can be used by more than one Oracle Schema.
So, my question is:
Should I load the package in every Schema ? Or should I load the package in the System (for instance) schema, creating synonyms for it (if possible) ? Or should I create both the package and the Stored Procedure in System, creating synonyms for the procedure ?
I'm a little stuck in this....
Another question : when my trigger fires, it launch the Stored Procedure and, consequently, my Java Package.... At this point, am I in the same transaction of the trigger ? Or the Java Package start a new "subtransaction" ?
Thanks in advance for Your help.
Best Regards
Fabio GRANDE

Do not create anything in the System schema. Create the package and procedure in one schema and create a public synonym that the other schemas can use to access it.
And yes the trigger and anything it executes are all part of the same transaction. As long as none of the procedures are declared as an autonomous transaction, in which case that procedure would be a separate transaction.

Diif between Stored procedure and function

HI
I want all the differences between Stored procedure and function.
Even the basic diff is Procedure does not return any value and Function must be...
Thansk In advance...

1) Functions are used for computations where as procedures can be used for performing business logic That's an opinion on usage not an actual difference.
3) You can have DML(insert,update, delete) statements in a function. But, you can not call such a function in a SQL query.Not true. As User defind functons limitations we can use a function that issues DML in a SELECT statement, if it uses the PRAGMA AUTONOMOUS_TRANSACTION.
4) Function parameters are always IN, no OUT is possibleEasily refutable...
SQL> CREATE OR REPLACE FUNCTION my_f (p OUT NUMBER) RETURN DATE
