Question

I’m looking to create a procedure that helps with debugging specific variables, and for the sake of re-usability I’d like to store it in it’s own procedure and pass in the specific variable when needed such as

debugz(var_x);

and the debug procedure would do the following –

PROCEDURE debugz (var_x VARCHAR2(1000))
AS
BEGIN
DBMS_OUTPUT.put_line ('Variable value: '|| var_x || ' | Line number: ' || $$plsql_line ||' | Unit: '|| $$plsql_unit);
END;

The problem is, I want the PL/SQL line number and PL/SQL unit to be based off of where the procedure call originates, i.e. the line/unit of “debugz(var_x);“. Is there anyway for debugz to output that line number without passing in additional information?

Check out DBMS_UTILITY.FORMAT_CALL_STACK

You may need/want to parse the output depending on your exact requirements, but may be a good place to start.

Oracle 10g onwards.

Also note DBMS_UTILITY.FORMAT_ERROR_BACKTRACE and DBMS_UTILITY.FORMAT_ERROR_STACK for error handling.
