Let's see what happens when I add an exception section to the proc3 procedure and then display the error information (the simplest form of error logging). BACKTRACE_DEPTH : The number of backtrace messages on the error stack. That way, I can avoid hard-coding these values later in my program (and possibly more than once). On the one hand, we should be very pleased with this behavior.

Pl/sql Line Number

CREATE OR REPLACE PROCEDURE display_call_stack AS l_depth PLS_INTEGER; BEGIN l_depth := UTL_CALL_STACK.dynamic_depth; DBMS_OUTPUT.put_line('***** Call Stack Start *****'); DBMS_OUTPUT.put_line('Depth Lexical Line Owner Edition Name'); DBMS_OUTPUT.put_line('. 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,

Is their no other means by which we can achieve this. SQL> BEGIN 2 EXECUTE IMMEDIATE 'garbage'; 3 END; 4 / BEGIN * ERROR at line 1: ORA-00900: invalid SQL statement ORA-06512: at line 2 There are many PL/SQL developers who consider In this example, it was at "HR.P1", line 5. What Are The Methods There In Save Exceptions In Oracle 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.

The question is how to find that line number. http://stackoverflow.com/questions/1589252/is-there-a-way-to-get-the-line-number-where-an-exception-was-thrown 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.

As soon as you issue a RAISE of a particular exception or re-raise the current exception, you restart the stack that the backtrace function produces. Pl Sql Call Stack The biggest problem I've found is that the pcode doesn't include blank lines and in long blocks the line numbers can get seriously out of whack. The DBMS_UTILITY.FORMAT_ERROR_BACKTRACE provides the error stack all the way back to source. 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.

Oracle Error Stack Trace

I want to... In Oracle Database 10g Release 1 and above, you can take advantage of the new function DBMS_UTILITY.FORMAT_ERROR_BACKTRACE. Pl/sql Line Number What I do then is add some step-names to the procedure like : declare v_step varchar2(10); begin v_step = 'INIT'; -- do something v_step = 'CALCULATE'; -- do something v_step = How To Find Which Line Error Was Raised? Reading the stack from top to bottom, note that the exact points at which the exceptions were encountered are preserved.

For example, prior to 10gR1: SQL> CREATE OR REPLACE PROCEDURE p1 2 IS 3 BEGIN 4 DBMS_OUTPUT.put_line ('in p1, raising error'); 5 RAISE VALUE_ERROR; 6 END; 7 / Procedure created. news Of course, there is always room for improvement, and in Oracle Database 10g, exception handling takes a big step forward with the introduction of the DBMS_UTILITY.FORMAT_ERROR_BACKTRACE function. Finally, with the release of 10g, Oracle has added provision for PL/SQL developers to trap AND log exceptions accurately for the first time. But if we don't use exception block line number is also displayed. $$plsql_line

Carrying Metal gifts to USA (elephant, eagle & peacock) for my friends Why are planets not crushed by gravity? The first line of the stack is where the exception was raised. Therefore, an important distinction needs to be made between application code that needs to be logged and that which doesn't. have a peek at these guys Is this a good alternative to DBMS_UTILITY.FORMAT_ERROR_BACKTRACE?

DDoS ignorant newbie question: Why not block originating IP addresses? Dbms_utility.format_call_stack Example This issue has been resolved in 10g or 11g, and 9iR2 is going completely out of support in July.FORMAT_ERROR_STACK will not provide any line numbers: SQL> select * from v$version l_depth LOOP DBMS_OUTPUT.put_line( RPAD(i, 10) || RPAD(TO_CHAR(UTL_CALL_STACK.backtrace_line(i),'99'), 10) || UTL_CALL_STACK.backtrace_unit(i) ); END LOOP; DBMS_OUTPUT.put_line('***** Backtrace End *****'); END; / -- Run the test.

The output includes the procedure names in the package as well as the associated line numbers of the calls.

Format_error_stack Vs Format_error_backtrace It has always been possible in PL/SQL to identify the source of an exception in a block of code; i.e.

Recognizing that I will be needing to parse the contents of a string based on various delimiters, I define a number of constants to hold these delimiter values.

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. SQL> SY. The only difference is that the DBMS_UTILITY.FORMAT_ERROR_STACK function appends a line feed! CREATE OR REPLACE PROCEDURE display_backtrace AS BEGIN DBMS_OUTPUT.put_line('***** Backtrace Start *****'); DBMS_OUTPUT.put_line(DBMS_UTILITY.format_error_backtrace); DBMS_OUTPUT.put_line('***** Backtrace End *****'); END; / -- Test package to show a nested call.

ERROR_MSG : The error message associated with the current line in the error stack. I then re-raise the same exception using the RAISE statement. The very first step in my info function is to perform a set of INSTR calls to identify the starting and ending locations of the various elements of the string that Let's use this function in the exception section of procedure p3: SQL> CREATE OR REPLACE PROCEDURE p3 2 IS 3 BEGIN 4 DBMS_OUTPUT.put_line ('in p3, calling p2'); 5 p2; 6 EXCEPTION
