Procedure to check the existence of Indexes

I have a procedure whcih drops all the indexes, when the same procedure is executed again, it gives error "object does not exists" (obviously)
I want to avoid this error, how can I check the existence of index inside the procedure, so that the procedure will check if the index exists before deleting the index?
Is there a ready-made procedure available for such scenario?
Thanks in advance

The other approach is to catch the exception in your script, i.e.
BEGIN
EXECUTE IMMEDIATE 'DROP INDEX <<index name>>';
EXCEPTION
WHEN OTHERS THEN
-- Drop failed. Do something to record the failure.
NULL;
END;Now, most of the time, you'll want to catch a few specific exceptions and you'll want to do something when you catch them (i.e. generate a log entry).

How to check the existence of DB400 library from java

Hi all,
I actunally need to validate a DB400 library via java. so is there any way to check the existence of DB400 library from java side.
Thanks in advance.

Hi Sarvan,
You might not even need a function to tell you if a record exists or not.
Here in below example i do a check with exists .you will find couple of other ways too..
create table t as select * from emp where deptno=10now i set salary of every person present in table 'T' to 1111 in emp table.
update emp e
set sal=1111
where exists
        (select 1
          from t
          where t.empno=e.empno) Remember that plain SQL will always outperform PLSQL.
Hope it helps

How to check the existence of file without any error dialog?

Hi everybody,
I am trying update some labview programs from LV6.1 to LV7.1, I used the
function "File/Dictionary Info" to check if the file
exists or not (if the size=0 then file does not exist), and it ran well with
LV6.1, but now it shows every time a labview error dialog
about "LabView: file not found..." with 7.1, if this file dosn't exist.
Sometimes I feel that it is really stupid to show the dialog, because I
can write handling by myself, if the error should be handled, and
I don't want all the process is interrupted because of such dialogs. Is
there any way to shut the dialog down or check the existence of
file smoothly?
Thanks a lot!
L.Wang

Hello,
The dialog is probably appearing because you have Auto Error Handling turned on. This feature is turned on by default in LabVIEW 7.0. You should go to VI Properties (Ctrl-I) > Execution and deselect "Enable automatic error handling". Also you should go to Tools > Options > New and Changed in LabVIEW 7.x and deselect "Enable automatic error handling in new VIs". If you never want to see one of those dialogs again, you can also deselect "Enaeble automatic error handling dialogs"...I wouldn't recommend this, however, as you would never know if one of your VIs had this setting enabled...you would only find out once somebody else tried to use your VI on another LabVIEW install.

Programmatically check the existence of objects in the system

Hi,
Is there a way to programmatically check the existence of objects? The idea is I'll accept a list of names of objects and their object types and then programmatically check their existence in the system?
Can you point me to a resource on how to do it?
Thanks in advance.

Hi.
All custom objects (z, y) being referred to a program. May it be z or y table, data element, domain, sapscript form, function module/group.
The goal is actually to be able to transport a program from a source machine to a target machine. The objects being referred to from the program must also be transported, of course, for it to run properly. Thus, the need to check the objects' existence.
Thanks.

Any means to check the existence of a .pdf file before opening in SAP GUI

Dear,
I've learnt from one of the thread that there is a sample program SAP_PDF_VIEWER_DEMO that allows us to open a .pdf file within a SAP windows.
However, I would like to know if there are any means to perform a checking on the existence of the .pdf file first before calling the method open_document as coded in the demo program.
Thanks a lot for your advise in advance,
Francis

where is this pdf file is ? in user desktop?
if yes you can simply use cl_gui_html_viewer for viewing pdf files. and you can use cl_gui_frontend_service=>file_exists method to check whether the file exists

How to check the existence of a storeProcedure

Hello everyone,
today I discovered how to call an oracle store procedure with jdbc classes, and it's been easy with tutorials and reading posts on this forum.
The problem I have is the following:
if i try to execute a store procedure which does not exist on the oracle schema with this code:
try{
con = DriverManager.getConnection(databaseurl,username,password);
cstmt = con.prepareCall"{call procedure_that_not_exist(?,?,?)}";
cstmt.setString(1, "try");
cstmt.registerOutParameter( 2, Types.VARCHAR );
cstmt.registerOutParameter( 3, Types.VARCHAR );
cstmt.executeUpdate();
catch(Exception e)
e.printStackTrace();
System.out.println(e.getMessage());
I get the following error:
ORA-06550: line 1, column 7:
PLS-00201: identifier 'PROCEDURE_THAT_NOT_EXIST' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
how is it possible to check before getting this "not specific error" wheter the procedure exist on the database schema?
Thank you!
Gianni

I mean the error PLS-00201 is not only related to the
fact that the procedure does not exist, but more
generally to "identifiers". (what are identifiers?)The 'name' of something. So, using your example code the following is an identifier....
procedure_that_not_exist
Other identifiers are variables in procs, table names, field names, constraint names, etc.

Checking the existence of a file b4 creating a file by the same name

Hi All,
I hav a scenario where I hav to check for the existence of a file by the same name (XXXFile say). If i don't hav any file by the name XXXFile, then i hav to create a file by the name XXXFile at that location. If it already exists, then i hav to wait till it gets deleted (takes hardly 1 min to get deleted).
Can any one tell me :
How to do this without using operating system command?
And using operating system command?
Any help wud be appreciated.
Thnx in Adv
Anil

Hi Anil,
You will i guess have a standard format in which you are going to write the file with a counter or something.
Whenever you are going to write a file, you can:
1. Check if there is a file already sent by this name?
2. If no, then you can send the file at the same time update the name.
You can do this by creating a ztable in SAP and accessing it through JCO/RFC. You can do this in your module or in the mapping.
eg. /people/jayakrishnan.nair/blog/2005/06/20/dynamic-file-name-using-xi-30-sp12-part--i

Check the existence of sales order

Hi all,
I am working on the scenario Jdbc to SAP(BAPI's).In Jdbc there is a flag field which indicates the status whether it is create or update or delete.I am using recieve and steps in BPM.
If it is create i have to first check whether already sales order is presented in the SAP data base.If it is already there ,then it must update the existing salesorder with create option.
similarly with update also...
How can i check the data existed in SAP database in BPM ?
Could anybody please help me?
Thanks,
sekhar.

you receive a jdbc "data type" and you want to post an rfc to check if the sales order is created so
you have to map the "jdbc" to RFC (transformation step)
then after the swith you can map your "jdbc" again to your z_bapi which now will create or update a sales order for instance
now a little bit clearer?

File problem - checking the existence of a remote file

I have absolute paths to several text files from a ftp server (which don't require any
authentication and can be accessed over the internet).
I am trying to write a Java method that can check any of the above absolute ftp file
paths and returns true/false depending on whether the file exists/doesn't exist.
I tried somewhat this way:
File current_file = new File(absolute_file_path);
// absolute_file_path comes as a parameter
// e.g. "ftp://ftp.test.com/myfile.txt"
if(current_file.exists()) return true;
// if the file exists return true
return false;
// otherwise return false
Then I ran the program in my local machine which has internet access. But it returned
false for all the files (even if the file exists). Seems like it's unable to get those
files.
Could someone please tell me how can I rewrite my program so that it can be executed
locally.
Thanks,
SQ

Does anyone know if URL and URLConnection support FTP
directly? I can imagine downloads being simple, but
how about uploads? Never tried with FTP myself.Yes, they do. But uploads don't work properly with Java 1.3. (Note: I only know this because I've seen questions asked about it here, not from personal experience.) If I wanted to know whether a certain file existed on an FTP server, I would use an FTP client that could tell me that. Such as the Jakarta Commons/Net FTP client.
