Who Raised That Exception? Not the answer you're looking for? 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 l_depth LOOP DBMS_OUTPUT.put_line( RPAD(i, 10) || RPAD('ORA-' || LPAD(UTL_CALL_STACK.error_number(i), 5, '0'), 10) || UTL_CALL_STACK.error_msg(i) ); END LOOP; DBMS_OUTPUT.put_line('***** Error Stack End *****'); END; / -- Run the test.

Dbms_utility Backtrace The DBMS_UTILITY.FORMAT_ERROR_STACK function differs from SQLERRM in two ways: It can return an error message as long as 1,899 characters, thereby avoiding (or at least making extremely unlikely) truncation issues when In my mind it is fairly clear that the various utility packages I include in my overall application will not handle unexpected exceptions in any way. 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.

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, Another approach is to call the function in the exception section of the block in which the error was raised.

Thanks. The question is how to find that line number. Is it possible to have more than one AD server with FSMO roles installed on it? What is a tire speed rating and is it important that the speed rating matches on both axles?

Here are some things to keep in mind about UTL_CALL_STACK: Compiler optimizations can change lexical, dynamic, and backtrace depth, because the optimization process can mean that subprogram invocations are skipped. Why not to cut into the meat when scoring duck breasts? Database as a Storage (DBaaS) vs. Line 14 calls the LEXICAL_DEPTH function to display the depth in the stack of each entry.

Answer to Previous Challenge The PL/SQL Challenge question in last issue’s “SQL in PL/SQL Enhancements” article focused on enhancements for executing SQL from PL/SQL in Oracle Database 12c. SET SERVEROUTPUT ON EXEC test_pkg.proc_1; ***** Error Stack Start ***** Depth Error Error . In many applications, however, we work to avoid unhandled exceptions.
