Quick note. During my 18.104.22.168 to 19c upgrade that I have been writing about we found a difference in behavior of DBMS_UTILITY.FORMAT_CALL_STACK. I tested it on several versions, and it switched in 12.2. Now it puts the procedure name within the package in the stack.
----- PL/SQL CALL STACK ----- OBJECT LINE OBJECT HANDLE NUMBER NAME 0X15BFA6930 9 PACKAGE BODY MYUSER.MYPKG 0X10C988058 1 ANONYMOUS BLOCK
----- PL/SQL CALL STACK ----- OBJECT LINE OBJECT HANDLE NUMBER NAME 0XA796DF28 9 PACKAGE BODY MYUSER.MYPKG.MYPROC 0X7ADFEEB8 1 ANONYMOUS BLOCK
select * from v$version; CREATE OR REPLACE PACKAGE MYPKG AS PROCEDURE MYPROC; END MYPKG; / SHOW ERRORS CREATE OR REPLACE PACKAGE BODY MYPKG AS PROCEDURE MYPROC IS BEGIN DBMS_OUTPUT.PUT_LINE(UPPER(dbms_utility.format_call_stack)); END MYPROC; END MYPKG; / SHOW ERRORS; execute mypkg.myproc; show errors;
Might be useful to someone else. We had some code that depended on the package name being the last thing on its line, but the new version includes the name of the procedure after the package name.
