The Oracle "insert into errors" feature is not good for much of anything, so what most people do is build a custom logging subsystem. CREATE OR REPLACE PACKAGE BODY plch_pkg IS PROCEDURE proc1 IS PROCEDURE nested_in_proc1 IS BEGIN DBMS_OUTPUT.put_line ( UTL_CALL_STACK.CONCATENATE_SUBPROGRAM ( UTL_CALL_STACK.SUBPROGRAM (1))); END; BEGIN nested_in_proc1; END; END plch_pkg; / c. Why Oracle does not show values for all binds? http://back2cloud.com/pl-sql/pl-sql-error-stack.php
This article explores the problem that this function solves and how best to use it. In Listing 4, I create and execute a function named BACKTRACE_TO that “hides” the calls to the UTL_CALL_STACK subprograms. SET SERVEROUTPUT ON EXEC test_pkg.proc_1; ***** Error Stack Start ***** ORA-00001: unique constraint (.) violated ORA-06512: at "TEST.TEST_PKG", line 16 ORA-01422: exact fetch returns more than requested number of rows ORA-06512: All of these drawbacks are addressed by the new-in-Oracle Database 12c UTL_CALL_STACK package. i thought about this
Code Listing 3: Re-raising exceptions to the outermost block in the stack CREATE OR REPLACE PROCEDURE proc1 IS BEGIN DBMS_OUTPUT.put_line ('running proc1'); RAISE NO_DATA_FOUND; EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.put_line ( 'Error SQL> CREATE OR REPLACE PROCEDURE p2 2 IS 3 BEGIN 4 DBMS_OUTPUT.put_line ('in p2'); 5 DBMS_OUTPUT.put_line ('calling p1'); 6 p1; 7 END; 8 / Procedure created.

So I would say the bind #2 is the problematic one where this exception is raised (unless your app code somehow binds values in a different order) Reply Filippo says: July Let's call p3: SQL> set serveroutput on SQL> BEGIN 2 DBMS_OUTPUT.put_line ('calling p3'); 3 p3; 4 END; 5 / calling p3 in p3, calling p2 in p2 calling p1 in p1, It will aid greatly in resolving the cause of the error. Utl_call_stack The error stack allows you to display chains of errors, making it easier to determine the real cause of the issue.
Do I need to do this? What does the image on the back of the LotR discs represent?

Skip to content Home Java, SQL and jOOQ. Dbms_utility.format_error_backtrace 11g If you simply want the name of the most recently executed subprogram, you will have to parse the string. Better Diagnostics, Better Programming The three DBMS_UTILITY functions (DBMS_UTILITY.FORMAT_CALL_STACK, DBMS_UTILITY.FORMAT_ERROR_STACK, and DBMS_UTILITY.FORMAT_ERROR_ BACKTRACE) have been crucial aids in diagnosing and resolving problems in PL/SQL code. SQL> CREATE PROCEDURE will_error AS 2 BEGIN 3 RAISE PROGRAM_ERROR; 4 END; 5 / Procedure created.

Absolute value of polynomial Why do units (from physics) behave like numbers? In a simple example such as the following, the output is very simple and provides the accurate information we require.

The UTL_CALL_STACK package contains APIs to display the contents of the call stack in a more readable form.
The developer of the application might even like to display that critical information to the users so that they can immediately and accurately report the problem to the support staff. In previous releases this information was displayed using the DBMS_UTILITY.FORMAT_ERROR_BACKTRACE function, as shown below. -- Procedure to display the call stack. BACKTRACE_LINE : Line number in the subprogram of the current call. Dbms_utility Backtrace With these locations established, I can now use SUBSTR to extract the desired portions and assign them to the fields in my record to be returned to the calling program, as
The UTL_CALL_STACK package recognizes the importance of this data and takes a big step forward in giving PL/SQL developers access to more in-depth and useful information. True to the nature of all things called "UTILITY", it really contains pretty much random things that you wouldn't expect there🙂 Everytime you read an excellent article and don't share it, I then use the format_call_stack_12c procedure (in Listing 2) in the pkg.do_stuff procedure and execute that procedure, as shown in Listing 3. see here CREATE OR REPLACE PROCEDURE display_error_stack AS l_depth PLS_INTEGER; BEGIN l_depth := UTL_CALL_STACK.error_depth; DBMS_OUTPUT.put_line('***** Error Stack Start *****'); DBMS_OUTPUT.put_line('Depth Error Error'); DBMS_OUTPUT.put_line('.

However, until Oracle 10g, it has not been possible for developers to intervene in the exception in any way whilst retaining this information (for example to record the exception and its Would you believe that before Oracle 10g there was no normal way to get the trace? l_depth LOOP DBMS_OUTPUT.put_line( RPAD(i, 10) || RPAD(UTL_CALL_STACK.lexical_depth(i), 10) || RPAD(TO_CHAR(UTL_CALL_STACK.unit_line(i),'99'), 10) || RPAD(NVL(UTL_CALL_STACK.owner(i),' '), 10) || RPAD(NVL(UTL_CALL_STACK.current_edition(i),' '), 10) || UTL_CALL_STACK.concatenate_subprogram(UTL_CALL_STACK.subprogram(i)) ); END LOOP; DBMS_OUTPUT.put_line('***** Call Stack End *****'); END; / When the exception propagates to the outermost block, I call the backtrace function again, and this time it shows that the error was raised on line 11 of proc1.

How to make your world’s revolutions feel realistic? SQL> CREATE OR REPLACE PROCEDURE p3 2 IS 3 BEGIN 4 DBMS_OUTPUT.put_line ('in p3, calling p2'); 5 p2; 6 END; 7 / Procedure created.
Why would breathing pure oxygen be a bad idea? On the other hand, we got this information by letting the exception go unhandled. One of the greatest improvements of UTL_CALL_STACK over DBMS_UTILITY .FORMAT_CALL_STACK is that you can obtain a unit-qualified name, which concatenates the unit name, all lexical parents of the subprogram, and the Thanks.
