How to Execute a Model

I created an abap routine call Get_BPList. It does a very simple select and brings back 3 fields. I tested the function module and it works ok.
I just want to execute it in dynpro and fill a dropdown list
I created a model and pointed it to the RFC ok and it generated a model. My problem is that my RFC is very simple on the ABAP side. It has no inputs or outputs, just one table (BPList). The model it generated has three nodes ZBP_Getlist_Input, ZBP_Getlist_Output, and ZBP_List.
Which one do I use in the context mapping and how do I execute the RFC?
Appreciate the help and will award points...
Regards,
Tom

Hi Thomas
Create a custom controller , right click it and apply service controller pattern , choose the ZBP_Getlist_Input for binding . This will generate the necessary code for you which includes an execute method. Attach this execute method to an action in the view.

How to Transper data Model Node to Vallue Node

Hi Friends

how to Transper data Model Node to Vallue Node. By using vallue node that data will display in table format with Check box.
I need data display in table format with Check box
Regards
Vijay Kalluri

Hi Vijay,
TO copy values from Model Node to Value Node use the copyElements() method of the WDCopyService API. To acheive this, the name and type of the attibutes in the Value Node should be same as Model node attributes.
Example: -
Model Node <----
> Value node
---Name-String                                       ---Name - String
---Number-Integer                                  ---Number - Integer.
then use the following statement:
WDCopyService.copyElements(wdContext.node<ModelNode>(),wdContext.node<ValueNode>());
This will copy all the values.

How to change the model of JSpinner

Hello, just want to ask how to change the model of a JSpinner during run time...
I have an existing JSpinner
example:
SpinnerNumberModel model = new SpinnerNumberModel( 2, 2, 4094, 1);
jSpinner = new JSpinner(model);
if (changeLimitTo255 == true) {
model = new SpinnerNumberModel( 2, 2, 255, 1);
jSpinner.setModel(model);
The problem is, the limit is always 4094, limit doesn't change to 255.
Thanks...

If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.

How to execute a script(.sql) file from a PL\SQL procedure

I would like to know how to execute a .sql file from a stored procedure and the result of it should update a table. My .sql file contains select statements.

Hi!
just go through the following piece of code -
SQL> ed
Wrote file afiedt.buf
1 declare
2    str varchar2(200);
3 begin
4    str := '@C:\RND\Oracle\Misc\b.sql';
5    execute immediate(str);
6* end;
SQL> /
declare
ERROR at line 1:
ORA-00900: invalid SQL statement
ORA-06512: at line 5ORA-00900: invalid SQL statement
Cause: The statement is not recognized as a valid SQL statement. This error can occur if the Procedural Option is not installed and a SQL statement is issued that requires this option (for example, a CREATE PROCEDURE statement). You can determine if the Procedural Option is installed by starting SQL*Plus. If the PL/SQL banner is not displayed, then the option is not installed.
Action: Correct the syntax or install the Procedural Option.

How to execute a SELECT statement in java??

Hello !!
In my java program , i need to delete a record of number X, so
i accept the number X from the keyboard
Then before deleting it
i want the program to show me the name, age of the record which has the number X
How to do this

hello kylas
actually i didnt get why this program example?? wats
its executing ??? Look at reply #3 in your other thread:
http://forum.java.sun.com/thread.jspa?threadID=713289&messageID=4126346
Notice the similarity? You've now asked "How to delete a record in Java" and "how to execute a select statement in java". You may have noticed that, aside from the SQL and the call to execute and executeUpdate (for delete) it's the same code. This is because you don't so much do these things in Java, you do them in SQL. The Java code simply asks the Driver to execute whatever SQL you write. So, I really hope your next post isn't "how do I execute an UPDATE statement in Java".
Good Luck

How to execute multiple queries in one stored procedure.

How to execute multiple queries in one stored procedure.
here is the my requirements,
1. get the max value from one table and sum of the that value.
2. insert the values and also sum of the max value.

I am using SQL server 2000 database.
Please help me.
Advance thanks

This is not a java question and it is not even a problem: your only problem is
1) lack of knowledge
2) lack of interest to find a manual
But you are going to have to change both by actually reading a book or a manual that explains the stored procedure language of SQL Server. It is the same as Sybase I think, so you could also look for a manual for that DBMS.

How to Execute a Remote Procedure in Portal using Database Link

Hi,
I followed the instructions to create a Portal form for a remote procedure. But I am encountering the following error. Can someone advise what may be the cause?
Failed to execute - Missing string(create_package_body) language(us) domain (wwv) sub_domain (wwv_builder) (WWV-04300)
ORA-04020: deadlock detected while trying to lock object PUBLIC.PORTLET_SCHEMA (WWV-11230)
Failed to parse as PORTAL - (WWV-08300)
PURPOSE
How to execute a remote procedure in Portal using Database Link.
DESCRIPTION
This procedure assumes that you have two databases, one of which is remote, and Portal is configured in the other.
Remote Database A:
==================
1) Create a procedure as follows: Create or Replace PROCEDURE SCOTT.ADD_TWO_VALUES ( v_one IN NUMBER, v_two IN NUMBER, v_result OUT NUMBER) as begin v_result :=v_one+v_two; end; 2) Grant execute privileges to PUBLIC on the procedure.
Database B (where Portal is configured): ========================================
1) Create a public database link and choose to connect as a specific user (say SYSTEM). By default, in an Oracle 8i database, the "global_names" parameter in initSID.ora (or init.ora) file is set to "true". This Global Naming parameter enforces that a dblink has the same name as the database it connects to. Therefore, if the remote global database (A) name is "ora8.acme.com" then the database link should also be named as "ora8.acme.com".
2) Create a synonym for the procedure in Database A. Make sure you fully qualify the procedure name in the remote database (like SCOTT.ADD_TWO_VALUES).
3) Create a dynamic page to execute the procedure. The ORACLE tags in the dynamic page will look similar to the following: <ORACLE> DECLARE v_total NUMBER; BEGIN ADD_TWO_VALUES(:v_one,:v_two, v_total); htp.p('The total is => '); htp.p('<input type="TEXT" VALUE='||v_total||'>'); htp.para; htp.anchor('http://<machine.domain:port#>/pls/portal30/SCOTT.DYN_ADD_TWO_VALUES.show_parms', 'Re-Execute Procedure'); END; </ORACLE>
4) Portal does not have an option to create a form based on a synonym. Therefore, if you want to create a form instead of a dynamic page, create a wrapper procedure and then create a form based on this procedure. For example: Create or Replace PROCEDURE PORTAL30.ADD_TWO_VALUES_PR ( v_one IN NUMBER, v_two IN NUMBER, v_total OUT NUMBER) as begin add_two_values(v_one, v_two, v_total); end;
5) Grant execute privileges to PUBLIC on the procedure.

1) it's not "taking more time to execute", whatever that's supposed to mean.
2) there's no other way to execute something. Not that you should every use even that way anyway
3) whenever you start thinking of executing external programs from Java, start thinking of not using Java in the first place.

How to execute an SQL query present in a string inside an ABAP program?

hello,
How to execute an SQL query present in a string inside an ABAP program

Raut,
You can execute Native SQl statements.
Ex: To use a Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement as follows:
EXEC SQL [PERFORMING <form>].
<Native SQL statement>
ENDEXEC.
There is no period after Native SQL statements. Furthermore, using inverted commas (") or an asterisk (*) at the beginning of a line in a native SQL statement does not introduce a comment as it would in normal ABAP syntax. You need to know whether table and field names are case-sensitive in your chosen database.
In Native SQL statements, the data is transported between the database table and the ABAP program using host variables. These are declared in the ABAP program, and preceded in the Native SQL statement by a colon (:). You can use elementary structures as host variables. Exceptionally, structures in an INTO clause are treated as though all of their fields were listed individually.
If the selection in a Native SQL SELECT statement is a table, you can pass it to ABAP line by line using the PERFORMING addition. The program calls a subroutine <form> for each line read. You can process the data further within the subroutine.
As in Open SQL, after the ENDEXEC statement, SY-DBCNT contains the number of lines processed. In nearly all cases, SY-SUBRC contains the value 0 after the ENDEXEC statement. Cursor operations form an exception: After FETCH, SY-SUBRC is 4 if no more records could be read. This also applies when you read a result set using EXEC SQL PERFORMING.
EXEC SQL PERFORMING loop_output.
SELECT connid, cityfrom, cityto
INTO :wa
FROM spfli
WHERE carrid = :c1
ENDEXEC.
Pls. Mark If useful
