SQL> Starting with the call to DISPLAY_CALL_STACK, we can work back through all the nested calls to the original anonymous block. The UTL_CALL_STACK package contains APIs to display the backtrace.

Hot Network Questions What is the most expensive item I could buy with £50? Compatibility The API described here is specific to V8 and is not supported by any other JavaScript implementations.

The format_call_stack_12c procedure in Listing 2 does precisely this. CREATE OR REPLACE PACKAGE test_pkg AS PROCEDURE proc_1; PROCEDURE proc_2; PROCEDURE proc_3; END; / CREATE OR REPLACE PACKAGE BODY test_pkg AS PROCEDURE proc_1 AS BEGIN proc_2; EXCEPTION WHEN OTHERS THEN display_backtrace;

Meta Stack Exchange is intended for bugs, features, and discussions that affect the whole Stack Exchange family of Q&A sites. SET SERVEROUTPUT ON EXEC test_pkg.proc_1; ***** Call Stack Start ***** Depth Lexical Line Owner Edition Name . UTL_CALL_STACK is a very handy utility, but for real-world use, you will likely need to build some utilities of your own around this package’s subprograms. lumberstack() ... >>> def lumberstack(): ...

isEval: does this call take place in code defined by a call to eval? The default stack trace is created using the CallSite API so any information that is available there is also available through this API. CREATE OR REPLACE PROCEDURE display_backtrace AS l_depth PLS_INTEGER; BEGIN l_depth := UTL_CALL_STACK.backtrace_depth; DBMS_OUTPUT.put_line('***** Backtrace Start *****'); DBMS_OUTPUT.put_line('Depth BTrace BTrace'); DBMS_OUTPUT.put_line('.

This document outlines V8's JavaScript stack trace API. DBMS_UTILITY.FORMAT_CALL_STACK. How can I get the key to my professors lab? SQL> BEGIN 2 EXECUTE IMMEDIATE 'garbage'; 3 EXCEPTION 4 WHEN OTHERS THEN 5 DBMS_OUTPUT.PUT_LINE( DBMS_UTILITY.FORMAT_ERROR_STACK ); 6 RAISE; 7 END; 8 / ORA-00900: invalid SQL statement BEGIN * ERROR at line

The following example recreates the DISPLAY_CALL_STACK procedure to use the UTL_CALL_STACK package, then re-runs the test. -- Procedure to display the call stack. If we wanted to, we could have displayed the output in reverse order, starting at the top-level call. -- Procedure to display the call stack. What does dot forward slash forward slash mean (.//)? New tech, old clothes Are there any rules or guidelines about designing a flag?

Framing "standalone" class output with "framed" and others Logical fallacy: X is bad, Y is worse, thus X is not bad Why is absolute zero unattainable?

The object handle value is, for all practical purposes, “noise.” PL/SQL developers—outside of Oracle, at least—never use it. Is there a role with more responsibility?

When collecting the stack trace all frames above the topmost call to this function, including that call, will be left out of the stack trace.

This function was necessary because in versions of Python prior to 2.3 when the -O flag was passed to Python the tb.tb_lineno was not updated correctly. Note that this means that positions can be nested if there are nested calls to eval, for instance: eval at Foo.a (eval at Bar.z (myscript.js:10:3)) If a stack frame is within ERROR_DEPTH : The number of errors on the error stack. Is there any correct way of formatting this kind of thing on StackExchange sites ?

This additional information is not available, however, for the error backtrace. Each string in the resulting list corresponds to the item with the same index in the argument list. The DBMS_UTILITY.FORMAT_ERROR_BACKTRACE function gives us the flexibility we have been demanding for years and the information that the DBMS_UTILITY.FORMAT_ERROR_STACK function simply didn't provide. 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('.

to know the precise point at which a block of code failed. The stack string proceeds from the most recent calls to earlier ones, leading back to the original global scope call. The quiz appears below and also at the PL/SQL Challenge (plsqlchallenge.com), a website that offers online quizzes on the PL/SQL language as well as SQL, Oracle Application Express, database design, and To set a different default value that affects all contexts use the --stack-trace-limit command-line flag to V8.

The DBMS_UTILITY.FORMAT_ERROR_BACKTRACE provides the error stack all the way back to source. Introduced in Oracle Database 10g, the DBMS_UTILITY.FORMAT_ERROR_BACKTRACE built-in function returns a formatted string that displays a stack of programs and line numbers tracing back to the line on which the error Skip to main content Select language Skip to search mozilla Mozilla Developer Network Sign in Sign in or create an account: GitHub Sign in: Persona Web Platform Technologies HTML CSS JavaScript For example, I recently had to debug another developer's procedure, which contained 98 separate UPDATE statements and one of them "in the middle somewhere" failed with an invalid number exception.

However, this is not hardcoded but only the default behavior and can be overridden by user scripts. The type of the this value (Type). This is useful when you want to print stack traces under program control, such as in a "wrapper" around the interpreter. V8 also has various hooks for controlling how stack traces are collected and formatted, and for allowing custom errors to also collect stack traces.

What is the difference between a crosscut sled and a table saw boat? It exactly mimics the behavior of the Python interpreter when it prints a stack trace. Lexical unit information is not exposed through UTL_CALL_STACK. This differs from print_tb() in the following ways: (1) if tb is not None, it prints a header Traceback (most recent call last):; (2)
