Capture return key from a field

Hi,
I have developed an application with a GUI interface from which the user has to input various values to the Jtext, radio buttons, and combo boxes. The values will then be written to the database.
My problem is I cannot go from the 1st field to the 2nd field using the 'Enter' key. It is stuck there. But I can navigate using the tab key. I need the enter key because I want to check whether the user has input any characters other than letters in the 1st field. Can anybody please help me with a sample code?

A JTextField interprets the "Enter" key as the ActionCommand. Any other type of GUI element needs to have a custom KeyListener added to it to make the "Enter" key do what you want.

Create a foreign key from a field that is part of a mulitple primary key

Hi,
i had a table named T_A, with a double primary key : (A,B)
Then i created a table named T_B with a field : C.
I want this field T_B.C to take only values that already exist in field T_A.A.
So i tried to create a foreign key on my field T_B.C, pointing on the field T_A.A : an error message appeared "not possible to create a foreign key on a field that is not a primary key".
How can i solve this....? If U have any idea, please mail me !!
THANX very much.

Add column A as foreign key into the table T_BHow?
(was the question from the original poster. Adding a column to table T_B that happen to have same name as the corresponding column in table T_A would not allow you to add the foreign key).
SQL> create table t_a (a number, b number, primary key(a, b)) ;
Table created.

Capture Return Value from Contextual Events Subscriber Method

Hi
I was wondering if anyone knew whether you could capture the return value from a method exposed as a subscriber for a contextual event?
Requirement: We have 2 bounded task flows (parent-child) with the child task flow embedded as a region in a view activity in the parent task flow. Based on an action in the parent task flow we raise a contextual event which calls an application module method exposed as a data control within the child task flow. We need to be able to capture the return value from the method on the managed bean.
Example method within child task flow application module:
public String contextualEventSub(){
Return "Y";
So here we would like to capture String value when the event is raised by the event producer (parent task flow action).
Within the Event Map on the page definition of the parent task flow view activity it is possible to set parameters to pass to the subscriber but it’s not obvious where you can capture the return value.
Many thanks!

Capture return code from system command?

Can someone please tell me what is the easiest way to capture the return code when executing a system command?
In other words I wish to execute a say a perl script and capture the return code from it.
Any help is appreciated.

How to capture return value from stored procedure?

Hi All,
I want to capture the retun values from this procedure to a table - CALL SYS.GET_OBJECT_DEFINITION('SCHEMA_NAME', 'TABLE_NAME').
The below approach is not working -
Insert into STG.STG_DDL
Call SYS.GET_OBJECT_DEFINITION('DWG', 'DWG_SITE')
Could you please have a look on the same?

How to return text from Text Field?

I'm an experienced VB programmer, but new to Dreamweaver, and
web programming. I need to put the text just entered by the user in
a form text field into a field farther down in the form- like when
your mailing address automatically populates into a shipping
address field. How to do?
Thanks
Bill Spencer

HI,
If i understand for you purpose you need to use a select list with redirect.
Then you have to put in the text field the code for displaying the corrisponding cities related to the code you choosed from the select list.
However that depends a lot about data and your app itself: If i understand you assume the postalcode is unique for a given city?
hope it helps

Capturing return status from a call to STARTRFC from a shell script.

Hi All
I am trying to use startrfc to integrate a Unix (Solaris) batch process with SAP. I want to determine whether an SAP user exists.
Here is the command as run in the Unix shell: -
startrfc -t -3 -h ourHost -s 01 -c 550 -l EN -u SAPuser -p secret -F BAPI_USER_EXISTENCE_CHECK -E USERNAME=testSAPuser
This command always exits with a status of zero, whether or not the user exists. (With the -t flag) It creates a file, dev_rfc and a second file of the form CPICTRCnnnnn. However there is no output to stdout, irrespective of whether testSAPuser exists.
Can I force this utility program to write its output to stdout instesd of writing it to a file? How?
Alternatively can I force the utility to write its output to a specific (named) file instead of writing to dev_rfc?
Thank you for your attention
Stephen Broadbridge

Hi,
You could create an RFC in SAP and put your BAPI function, an the result into a table parameters:
- use -T parameter to get the table
- use w to set your file
Example:
startrfc -E PEBELP=00010 -t -d AR1 -h S01AZ03A01 -s 10 -g S01AZ03A01 -x sapgw10 -u LOLA -p flores -c 130 -l EN -F Y_RFC_EXAMPLE2 -T RESULTADO,250,w=outputname.txt
Explanation of parameters:
-T <table name>,<width>,[r=<file>][,w=<file>]
Where <file> is a path name to read from (r) or write to (w) the internal table. If <file> is -, stdin or stdout is used.
Example of Y_RFC_EXAMPLE2
FUNCTION Y_RFC_EXAMPLE2.
""Local interface:
*" IMPORTING
*" VALUE(PEBELP) TYPE EBELP
*" TABLES
*" RESULTADO STRUCTURE TAB512
DATA fecha(10).
DATA wa TYPE string.
WRITE sy-datum TO fecha.
 CONCATENATE pebelp fecha INTO wa SEPARATED BY '/'.
 ds_rec 'sample' wa.
 append wa to resultado.
ENDFUNCTION.

Handling Return Codes from SQL Stored Procedures

Hi,
Please can you let me know how to take care of system return codes from Stored Procedure in JDBC program. Is there any way it can be handled using Callabale Statement.
Regards.

not sure what you mean by "system" return codes, but to capture return values from stored procedures you can use CallableStatement.registerOutParameter(), just like with output parameters. see http://www.j-netdirect.com/GenStoredProcedures.htm#ReturnStatus.

Remove carriage returns from a field in an oracle table

I have a field that is defined as a LONG in my oracle table; the data contained in this field has carriage returns/line feeds (it's free form text); as i'm selecting data from this field, i need the carriage returns removed so that the data from this field all appears on one line.
I tried using the TRANSLATE function to convert the carriage returns to something else, but that doesn't work.
Example:
Select comment from Notes:

How can i do this? Can the decode function be used to remove the carriage returns in this field?

How to remove carraige return from the field while loading external table

I am facing an issue of not getting rid of carraige returns present in the fileds of the source .csv file while loading the records into external table.
I had tried using LRTRIM, but it does not help.
The error I am getting is:
KUP-04021: field formatting error for field POPULATION_DESCRIPTION
KUP-04037: terminator not found
I am pasting one record out of the .csv file which is causing this error as below:
"Business Card Accounts
",123,7 BizCard - Gamers,Control,"Business Card Accounts
",75270,75271
You can see the carraige return in the 1st field as well as 5th field. Filed are separated by commas & eclosed by double quotes.
Could anybody help on this please?

Can you copy the file to an external table only version, and then dos2unix it?
Alternatively, you can use the ACCESS PARAMETERS area in your external table definition to set that your RECORDS DELIMITED BY carriage returns, instead of the default.
Check out the example here http://www.psoug.org/reference/externaltab.html

Capture keyboard characters without hitting return key

Is it possible to get a keyboard key typed character without requiring the user to enter the RETURN key?
For example, the user press a key and the screen will echo the key pressed in console mode, not in GUI mode.

Is it possible to get a keyboard key typed character
without requiring the user to enter the RETURN key?The shell that's running in your console window will not give the kay strokes to the rpogram until the human hits enter/return. This is so the shell can do all the editing (EG backspace, etc).
In unix you can put the console in 'raw' mode which lets every key stroke through. See the 'stty' command
