Debugging pl/sql that uses htp calls

I'm trying to run debug against a procedure that has htp calls in it but whenever I hit a htp.xxx call I get
$Oracle.EXCEPTION_ORA_6502:
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at "SYS.OWA_UTIL", line 356
ORA-06512: at "SYS.HTP", line 1368
ORA-06512: at "SYS.HTP", line 1443
ORA-06512: at "LUMWEB.DOHTP", line 3
ORA-06512: at line 2
Is there something that needs to be done to make this work? I'm able to debug the same procedure using pl/sql developer.

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device (iPhone) using debug build. When running with a release build, the result handler is never called (nor is the fault handler called). Viewing the BlazeDS logs in debug mode, the call is received and send back with data. I've narrowed it down to what seems to be a data size issue.
I have targeted one specific data call that returns in the String value a string length of 44kb, which fails in the release build (result or fault handler never called), but the result handler is called as expected in debug build. When I do not populate the String value (in server side Java code) on the object (just set it empty string), the result handler is then called, and the object is returned (release build).
The custom object being returned in the call is a very a simple object, with getters/setters for simple types boolean, int, String, and one org.23c.dom.Document type. This same object type is used on other other RemoteObject calls (different data) and works fine (release and debug builds). I originally was returning as a Document, but, just to make sure this wasn't the problem, changed the value to be returned to a String, just to rule out XML/Dom issues in serialization.
I don't understand 1) why the release build vs. debug build behavior is different for a RemoteObject call, 2) why the calls work in debug build when sending over a somewhat large (but, not unreasonable) amount of data in a String object, but not in release build.
I have't tried to find out exactly where the failure point in size is, but, not sure that's even relevant, since 44kb isn't an unreasonable size to expect.
By turning on the Debug mode in BlazeDS, I can see the object and it's attributes being serialized and everything looks good there. The calls are received and processed appropriately in BlazeDS for both debug and release build testing.
Anyone have an idea on other things to try to debug/resolve this?
Platform testing is BlazeDS 4, Flashbuilder 4.7, Websphere 8 server, iPhone (iOS 7.1.2). Tried using multiple Flex SDK's 4.12 to the latest 4.13, with no change in behavior.
Thanks!

After a week's worth of debugging, I found the issue.
The Java type returned from the call was defined as ArrayList. Changing it to List resolved the problem.
I'm not sure why ArrayList isn't a valid return type, I've been looking at the Adobe docs, and still can't see why this isn't valid. And, why it works in Debug mode and not in Release build is even stranger. Maybe someone can shed some light on the logic here to me.

Debugging a sourcecode that uses Antenna's "preprocessing" feature.

I wonder if there's a way to use Eclipse(or any other IDEs) to debug(stepping through, set breakpoints, etc.) a code that look something like this:
//#ifdef conditionA
public class Screen implements Runnable
//#else
public class Screen implements Runnable, CommandListener
I tried searching Eclipse's documentation for "preprocess" but found nothing.
Thanks in advance!

Buffer size for SQL statement using JDBC calls

I need to find out the buffer size for SQL statements in jave/JDBC because I need to insert or update a field that could be up to 4KB in size.

I'm not sure that I follow the question; I'm not sure which buffer size you're referring to.
If you have a field that can store up to 4k worth of data, you would create a VARCHAR2(4000) column in the Oracle database (assuming it is character data) or a BLOB column (if the data is binary). Either of those two fields can be populated from JDBC.

How to call Fortran .dll file that using other library files?

Hi,
I am trying to do some arkward tasks using LabView, and I am desperately need help....
A little bit background:
1. My co-worker has some code written in Fortran, where he called other libraries (many from CERNLAB or PAW). Those stuffs are pretty powerful in mathmatical calculation and simulations.
2. In some of my LabView code, I need to call his Fortran source code in order to do some complicated calculations. I have no capablility to translate his Fortran code to Labview (or is it even possible??), so we end up with trying to use "Call library function node" where I just provide input/outputs to communicate with his code. The idea sounds simple enough?
3. We complie the Fortran code into .dll, and then specifiy the dll in "Call library function node". The first try with a very simple Fortran code, something like c = a+b*a, was sucessful. The dll file and Call lib function worked good. It's sort of proved the concept.
4. Now I am trying more complicated Fortran code (say Test.dll), which calling other library (.lib files) that using typical "call xxx(a,b,c)" line, and my nightmare started.... It seems nothing was excuted when I call Test.dll in LabView.
Questions:
1. How do LabView know if the Test.dll code needs functions from other .lib files? Do I need to copy all the .lib files to a specific folder?
2. When I create .dll file, for LabView to be able to use it, are there any special requirement on the way the .dll is compiled?
3. Seems there is mismatch btw the data type in Fortran and LabView. For example, LabView's Signed 8-bit Integer seems different with a integer in Fortran. How can i know the correlation btw data type in different langurage, i.e. LabView vs Fortran?
4. Are there any good examples that I can take a look?
I would highly appreicate any suggestions/helps!
Rgds,
Harry

You are aware that Intel Visual Fortran is the successor to Compaq Visual Fortran (I think you made a mistype with the Virtual)? So an upgrade might be at its place.
Anyhow I'm really not familiar with Fortran at all, but lib files are usually compiled into an EXE or DLL and not loaded dynamically. 1)
So there should be no problem with locating those libs. What most likely is a problem are other DLL dependencies such as any Fortran Runtime library or possibly other third party DLLs the more advanced code in your DLL might be using.
Typically most compilers can be configured to link the runtime library code statically into the DLL, as altenbach reports for the Intel compiler, otherwise you must make sure to install the redistributable Fortran Runtime Library for your compiler. Besides that you must make sure to find out what other runtime dependencies your code might have and install them.
1) One exception I know of is LabWindows CVI which allows to also load lib files dynamically. This is supposedly a legacy feature from LabWindows for DOS, which allowed that feature to simulate dynamic module loading in order to swap modules at runtime to work around the 640k memory limitation of DOS.

Calling Console Application that uses WebBrowser from SQL Server - Not Running

Hi there. I am working in a program automation that needs to get files from a website and put it in a database. It is done but as I need a console application and need webbrowser that comes from Windows Forms, I am trying to call it from the SQL Server using
the xp_cmdshell but when it runs the .exe, it execute the block that is before the Application.Run() command but when it reaches this line, it stay running on Task manager but it not execute my code. How can I fix this? I had first created a Windows form application
but it was not working anyway and then I tried a console application and then I use the [STAThread] and Application.Run(). At least it runs the file from SQL Server but is not executing all my code, I think that it stops on Application.Run() line. Any help
will be very useful.
Thanks for now.

Thanks for the response. What I mean is that it just run the part of the code that is just using the Console, that's the code:
// Main Method
[STAThread]
public static void Main()
clearDatabase(myConnection);
Console.Title = "Suframa Itens Robot";
//If log file exists, it is deleted
if ( File.Exists(@"suframaLog.txt") )
File.Delete(@"suframaLog.txt");
wb.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(loginWebsite);
try
//It is called as the program uses the WebBrowser Class from Windows Forms namespace
//and it is a console Application
Application.Run();
catch ( Exception ex )
Log(ex.Message);
As you can see, I call a function on start named ClearDatabase, when I call the file from sql server it executes, the tables are cleared, but what I think is that the problem stop when reach the line Application.Run() as it is the line that allows the remaining
code to execute as it uses events from WebBrowser class.
It is a program automation that needs to get a lot of files from a website that needs login and read line by line from the files and put on server, if I call it from the executable it runs fine, the only problem is when calling from SQL Server, Do you know
how to fix this?
Thanks.

SQL report region source to call a pl/sql function using DB link

Hi - I have a pl/sql function fn_dbtype(id NUMBER) defined in database X. The pl/sql function executes couple DML statements and returns a string (a SELECT query). I am able to call this function using SQL Plus (Connected to Database X) as below and it works fine:
declare
vSQL VARCHAR2(100);
begin
vSQL := fn_dbtype(1);
end;
The DML operations completed fine and vSQL contains the "Select" query now.
In APEX:
I am trying to create a SQL report in APEX using SQL query(PL/SQL function returning a sql statement) option. I am trying to figure out what to put in the region source so that the output of the "Select" query is displayed in the report.
Moreover APEX is hosted in a different database instance. So I would need to call this pl/sql function using a DB Link.
Please let me know what I need to put in the region source to execute the pl/sql function which returns the "Select" query thereby displaying the query output in the report. Thanks.

SOLVED: How can I use or call a function that returns %ROWTYPE?

Hi
edit: you can probably skip all this guff and go straight to the bottom...In the end this is probably just a question of how to use a function that returns a %rowtype. Thanks.
Currently reading Feuerstein's tome, 5th ed. I've downloaded and run the file genaa.sp, which is a code generator. Specifically, you feed it a table name and it generates code (package header and package body) that will create a cache of the specified table's contents.
So, I ran:
HR@XE> @"C:\Documents and Settings\Jason\My Documents\Work\SQL\OPP5.WEB.CODE\OPP5.WEB.CODE\genaa.sp"
749 /
Procedure created.
HR@XE> exec genaa('EMPLOYEES');which generated a nice bunch of code, viz:
create or replace package EMPLOYEES_cache is
    function onerow ( EMPLOYEE_ID_in IN HR.EMPLOYEES.EMPLOYEE_ID%TYPE) return HR.EMPLOYEES%ROWTYPE;
    function onerow_by_EMP_EMAIL_UK (EMAIL_in IN HR.EMPLOYEES.EMAIL%TYPE) return HR.EMPLOYEES%ROWTYPE;
    procedure test;
end EMPLOYEES_cache;
create or replace package body EMPLOYEES_cache is
    TYPE EMPLOYEES_aat IS TABLE OF HR.EMPLOYEES%ROWTYPE INDEX BY PLS_INTEGER;
    EMP_EMP_ID_PK_aa EMPLOYEES_aat;
    TYPE EMP_EMAIL_UK_aat IS TABLE OF HR.EMPLOYEES.EMPLOYEE_ID%TYPE INDEX BY HR.EMPLOYEES.EMAIL%TYPE;
    EMP_EMAIL_UK_aa EMP_EMAIL_UK_aat;
    function onerow ( EMPLOYEE_ID_in IN HR.EMPLOYEES.EMPLOYEE_ID%TYPE)
        return HR.EMPLOYEES%ROWTYPE is
        begin
            return EMP_EMP_ID_PK_aa (EMPLOYEE_ID_in);
        end;
    function onerow_by_EMP_EMAIL_UK (EMAIL_in IN HR.EMPLOYEES.EMAIL%TYPE)
        return HR.EMPLOYEES%ROWTYPE is
        begin
            return EMP_EMP_ID_PK_aa (EMP_EMAIL_UK_aa (EMAIL_in));
        end;
    procedure load_arrays is
        begin
            FOR rec IN (SELECT * FROM HR.EMPLOYEES)
            LOOP
                EMP_EMP_ID_PK_aa(rec.EMPLOYEE_ID) := rec;
                EMP_EMAIL_UK_aa(rec.EMAIL) := rec.EMPLOYEE_ID;
            end loop;
        END load_arrays;
    procedure test is
        pky_rec HR.EMPLOYEES%ROWTYPE;
        EMP_EMAIL_UK_aa_rec HR.EMPLOYEES%ROWTYPE;
        begin
            for rec in (select * from HR.EMPLOYEES) loop
                pky_rec := onerow (rec.EMPLOYEE_ID);
                EMP_EMAIL_UK_aa_rec := onerow_by_EMP_EMAIL_UK (rec.EMAIL);
                if rec.EMPLOYEE_ID = EMP_EMAIL_UK_aa_rec.EMPLOYEE_ID then
                    dbms_output.put_line ('EMP_EMAIL_UK lookup OK');
                else
                    dbms_output.put_line ('EMP_EMAIL_UK lookup NOT OK');
                end if;
            end loop;
        end test;
    BEGIN
        load_arrays;
    end EMPLOYEES_cache;
/which I have run successfully:
HR@XE> @"C:\Documents and Settings\Jason\My Documents\Work\SQL\EMPLOYEES_CACHE.sql"
Package created.
Package body created.I am now trying to use the functionality within the package.
I have figured out that the section
    BEGIN
        load_arrays;
    end EMPLOYEES_cache;
/is the initialization section, and my understanding is that this is supposed to run when any of the package variables or functions are referenced. Is that correct?
With that in mind, I'm trying to call the onerow() function, but it's not working:
HR@XE> select onerow(100) from dual;
select onerow(100) from dual
ERROR at line 1:
ORA-00904: "ONEROW": invalid identifier
HR@XE> select employees_cache.onerow(100) from dual;
select employees_cache.onerow(100) from dual
ERROR at line 1:
ORA-06553: PLS-801: internal error [55018]
HR@XE> select table(employees_cache.onerow(100)) from dual;
select table(employees_cache.onerow(100)) from dual
ERROR at line 1:
ORA-00936: missing expressionHe provides the code genaa.sp, and a very brief description of what it does, but doesn't tell us how to run the generated code!
Now, I have just done some googling, and it seems that what I am trying to do isn't possible. Apparently %ROWTYPE is PL/SQL, and not understood by SQL, so you can't call onerow() from sql. Correct?
So I try wrapping the call in an exec:
HR@XE> exec select employees_cache.onerow(100) from dual;
BEGIN select employees_cache.onerow(100) from dual; END;
ERROR at line 1:
ORA-06550: line 1, column 30:

PLS-00221: 'ONEROW' is not a procedure or is undefined
ORA-06550: line 1, column 7:
PL/SQL: Statement ignoredNo joy.
Of course, now that I'm looking at it again, it seems that the way to go is indicated by the first error:
PLS-00428: an INTO clause is expected in this SELECT statement
So am I supposed to create a type of EMPLOYEES%ROWTYPE in a PL/SQL procedure, and the idea of this code, is that the first call to onerow() runs the initialiation code, which populates the cache, and all subsequent calls to onerow() (whether by my session or any other) will use the cache?
I've had a stab at this, but still, no joy:
create or replace procedure testcache is
    emp employees%rowtype;
    begin
        select employees_cache.onerow(100) from dual into emp;
        dbms_output.put_line('Emp id: ' || emp.employee_id);
    end testcache;

Ha, figured it out

Hopefully you also figured out that the example is just that: a technical example of how to use certain Oracle functionality. Unfortunately it is also an example of what you should NOT do in an actual application.
That code isn't scaleable, uses expensive PGA memory, has no limit on the amount of memory that might be used and, contrary to your belief will result in EVERY SESSION HAVING ITS OWN CACHE of exactly the same data if the session even touches that package.
Mr. Feuerstein is an expert in SQL and PL/SQL and his books cover virtually all of the functionality available. He also does an excellent job of providing examples to illustrate how that functionality can be combined and used. But the bulk of those examples are intended solely to illustrate the 'technical' aspects of the technology. They do not necessarily reflect best practices and they often do not address performance or other issues that need to be considered when actually using those techniques in a particular application. The examples show WHAT can be done but not necessarily WHEN or even IF a given technique should be used.
It is up to the reader to learn the advantages and disadvantages of each technicalogical piece and determine when and how to use them.

That is correct. To be used by SQL you would need to create SQL types using the CREATE TYPE syntax. Currently that syntax does not support anything similar to %ROWTYPE.

NO! That is a common misconception. Each session has its own set of package variables. Any session that touches that package will cause the entire EMPLOYEES table to be queried and stored in a new associative array specifically for that session.
That duplicates the cache for each session using the package. So while there might be some marginal benefit for a single session to cache data like that the benefit usually disappears if multiple sessions are involved.
The main use case that I am aware of where such caching has benefit is during ETL processing of staged data when the processing of each record is too complex to be done in SQL and the records need to be BULK loaded and the data manipulated in a loop. Then using an associative array as a lookup table to quickly get a small amount of data can be effective. And if the ETL procedure is being processed in parallel (meaning different sessions) then for a small lookup array the additional memory use is tolerable.
Mitigating against that is the fact that:
1. Such frequently used data that you might store in the array is likely to be cached by Oracle in the buffer cache anyway
2. Newer versions of Oracle now have more than one cache
3. The SQL query needed to get the data from the table will use a bind variable that eliminates repeated hard parsing.
4. The cursor and the buffer caches ARE SHARED by multiple sessions globally.
So the short story is that there would rarely be a use case where ARRAYs like that would be preferred over accessing the data from the table.

Encrypting communication between an app that uses an ODBC/DSN (with ADODB) and SQL Server 2008 R2

I've been doing a lot of reading the last couple of days on how we can encrypt db communication between our product app and a customer's SQL Server db, but cannot make it work as expected. The app uses a ODBC/DSN to connect to the SQL Server db. I use this
ODBC app to setup the DSN (on a Windows 7 PC):
C:\Windows\SysWOW64\odbcad32.exe
The DSNconnection uses the SQL Server driver 6.01.7601.17514 and has these properties:
- WinNT authentication.
- Client Config button: TCP/IP to <server-name>\<instance.-name>
- Change to default db: <name-of-app-db>
- Everything else is default setting.
SQL Server is on the same Windowns 7 PC and has a self-signed cert installed (used IIS to generate it) and has the Force Enryption set to "yes".
I have a test C# program that uses the ADODB 2.7.0.0 COM-wrapper, made by Visual Studio after adding a reference to the ADO 2.7 library version 6.1.7601.17857. The program creates an ADODB.Connection object that has a simple connection string: "DSN=<san-name>;UID=<user>;PWD=<password>". The
program then creates an ADODB.Recordset object and reads and displays a field from a table.
Works fine.
If I go into SQL Server and set Force Encryption to "no," clear the cert, restart the SQL service, and then re-run the program, it works fine.
Here's the kick. If I go into the DSN and select "Use strong encryption for data" the Test button on the DSN works—why does it work? The SQL Server is no longer encrypting the connection so an error should occur. If I run the test program, it works
as well—why? I can look at the connection properties in the test program and see that ADODB has added the ";Encrypt-yes" stuff to the end of the connection string. Yet that option seems to have no effect.
If I set the SQL instance back to Force Encryption:yes, enable the cert, restart the SQL service, and clear the DSN's "Use strong encryption for data" option, I can still connect to the db with the
test program—why?
What am I doing wrong? I need to be able to ensure that the communication between our app product and the SQL instance is encrypted, and that we get an error if the SQL instance does not support encrypted communications. We really don't want the customer
to have to enable Force Encryption because they have other db's on their SQL Server that do not use encrypted communication, but they want to know that our product's communication channel with the db is encrypted.
No, I can't change the app product's code at this point in time. I'm stuck with working with what a DSN called from ADODB has to offer.
Also, how can I be sure that communications are encrypted? I mean, I've tried things like "SELECT * FROM sys.dm_exec_connections" but that doesn't help because I have no idea how to tie the list of sessions shown back to my test program, although
I guess it's a good thing that some of the sessions listed show encrypt_option as TRUE.
-glenn-

Ah yes, very good point. It's easy to miss because you have to delete then recreate the DSN in order to change drivers. So I switched the DSN over to the SQL Native 11 driver.
Now when I try to connect to the SQL instance as <computer-name>\<instance-name>, and without a cert on the server, I get "the target principal name is incorrect". Perfect; now we're getting somewhere!
Change my DSN to use <fqdn>\<instance-name> and it works. This tells me that SQL Server has auto-generated a cert and named it <fqdn>. I would have expected the "cert fail" error, not a cert
name mismatch, because I'm not using Trust Server Cert.
So I load up my self-signed cert, and that works too.
I am still confused as to why I'm not seeing the "cert fail" error when I have no cert loaded on the SQL Server. I am not using Force Encryption on the server at all, so wouldn't expect SQL Server to auto-create a cert when an Encrypt=yes request comes in,
but apparently it does?
I also ran into a problem with this:
select c.session_id, c.encrypt_option, s.client_interface_name
from sys.dm_exec_connections c
join sys.sysprocesses s
on c.session_id = s.session_id
where s.dbid = db_id('MyDatabase')
There is no s.client_interface_name, probably should be s.hostname. There's also no s.session_id. I thought maybe this should be s.sid, but then no rows ever come back. The c.session_id looks like 51 and 52, but the s.sid looks like a very long binary number,
so these two fields cannot be joined. I don't know how to convert the sid's properly so that the join would work. Ah wait, I just found the s.spid column; the join works when that column is used (I assume that's correct anyhow).
If I add a Thread.Sleep(30 seconds) to my C# program just before the connection is closed, this query shows me the session for the correct hostname has encrypt_option=TRUE.
And I have to keep my fingers crossed that all the app I/O will still work properly after
changing the driver. Probably a safe bet though.
Think I'm ready to throw in the towel on getting the "cert fail/no SSL" error to appear.
It does look like I am able to sufficiently show that the connection is encrypted when Encrypt=yes is used with the newer driver.
Thank for all the help!

Call procedure that uses REF CURSOR?

Can someone tell me how to call a procedure that uses a REF CURSOR?
Procedure is something like this:
PROCEDURE my_proc
P_PROG_ID IN VARCHAR2,
P_CRITERIA IN VARCHAR2,
P_TASKCURSOR OUT MYREFCUR
IS
blah, blah blah
I tried this to call the procedure:
exec my_proc(variable1,variable2,variable3)
but I don't know how to define variable3.
Can someone help me out?

Based on the parameters for the procedure, it looks like you have a cursor (myrefcursor) defined in a package somewhere. So, in sqlplus, you would need to do it in an anonymous block, something like:
DECLARE
   l_cur package_name,myrefcur;
   variables to hold cursor fields
BEGIN
   my_proc('ID', 'Criteria', l_cur);
   LOOP
      FETCH l_cur INTO variables to hold cursor fields
      EXIT WHEN l_cur%NOTFOUND;
      Do something with variables
   END LOOP;
   CLOSE l_cur;
END;If you are on Oracle 9 or higher, assuming that myrefcursor is weakly typed,
you could change the definition of the procedure to:
PROCEDURE my_proc (p_prog_id    IN VARCHAR2,
                   p_criteria   IN VARCHAR2,
                   P_TASKCURSOR OUT SYS_REFCURSOR)then you could call it in sql plus like:
-- Define the variables
var var1 VARCHAR2(100);
var var2 VARCHAR2(100);
var cur SYS_REFCURSOR;
-- Assign Vlaues to the IN parameters
EXEC :var1 := 'ID'; :var2 := 'Criteria';
EXEC my_proc(:var1, :var2, :cur);
-- See the contents of the cursor
print curHTH

I'm running JDeveloper 10.1.3.2.0 on Windows XP (32-bit) SP2 connecting to a Oracle 10g 10.2.1.0 (64-bit) on UNIX.
I have compiled the packages and procedure using JDeveloper and can run the procedure using SQL*Plus but I when I try to run the procedure in JDeveloper
the "Run PL/SQL" dialogue appears, the Messages window shows: "Connecting to the database oradb01". I click OK and nothing seems to happen.
I have been told by my DBA that I have all the prerequisites to debug PL/SQL so I wonder if I am missing something. Can anyone help?
Thanks all,
LG

Brilliant. Thanks Shay,
The only thing I wasn't sure about was that I tried to use the IP address of my workstation (from ipconfig) in the DBMS_DEBUG_JDWP.CONNECT_TCP procedure and for some reason it wouldn't work, so I used the Windows full computer name instead and it worked fine.

How to obtain SQL that don't use bind variables

Hi,
I'm trying to identify the SQL that should benefit from using bind variables.
First, I tried to obtain the common signature from all those sql calls, by using:
select * from (
select force_matching_signature, count(1) from v$sql where force_matching_signature<>0 group by force_matching_signature order by 2 desc
) where rownum < 50;Then, I copied those values to clipboard and executed: select sql_text from v$sql where force_matching_signature=<<<copied_signature_value>>>;Now I want to make it automatically, and get just 1 occurrence of each SQL that is similar to others by using a query.
I've tried this:
select sql_text from
select sql_text, force_matching_signature, row_number() over (partition by force_matching_signature order by sql_text desc)rn from v$sql where force_matching_signature <>0
)where rn <2 and rownum < 10 order by force_matching_signature descBut this is not returning results by attending to the count(1) of the first query I used. How can I modify this so I get the results in order of 'importance'?
Thanks

And I said. First use order by, then use rownum. I didn't mention row_number. Also there should be no need to add any more columns.
Did you try it? Why didn't it work?
untested example
select * from (
   select sql_text from (select sql_text, force_matching_signature, row_number() over (partition by force_matching_signature order by sql_text desc) rn from v$sql where force_matching_signature != 0)
   where rn = 1
   order by force_matching_signature desc /* add any ordering you like here */
where rownum < 10 /* then filter on the first 10 results */If you want to order it in such a way that the statement that is found most times comes first then say so. However I do not see how to group in your case.
maybe like this
tested example
select * from (
   select cnt, sql_text
   from (select sql_text, force_matching_signature, row_number() over (partition by force_matching_signature order by sql_text desc) rn , count(*) over (partition by force_matching_signature) cnt
         from v$sql
         where force_matching_signature != 0)
   where rn = 1
   order by cnt desc, force_matching_signature desc /* add any ordering you like here */
where rownum < 10 /* then filter on the first 10 results */

How do you display the SQL that BEx uses?

All,
I would like to display the SQL that is submitted to BEx. I understand you can perform a SQL Trace (ST05), but I want to see the SQL before is submitted to BEx. Can anyone help me.
Thanks.

As Allison mentions - use RSRT, choosing Execute + Debug.
From there you will see an option, Display SQL Query, which may be what you want, it displays the SAP's Open SQL, but what you might relate better to is the Display Run Schedule, which will show the SQl as translated to the target DB environment and the Explain (execution) Plan.
Just as an FYI, ST04 is also useful for seeing the SQL and execution plans of a query that has already run. Check it out if you are not familiar with it.
