RE: PLSQL exception handling

        You might want to try dbms_utility.format_error_backtrace as follows:

declare a integer;
begin

   a := 'ABC';
exception when others then
dbms_output.put_line(DBMS_UTILITY.format_error_backtrace); end;
/
ORA-06512: at line 3

PL/SQL procedure successfully completed.

Subject: PLSQL exception handling

Oracle 11.2.0.1.0 (Linux x86-64).

I am writing stored procedure which copies information from one table to another, doing some transformations in the process. I am using the %rowtype construct for the fetches and inserts and doing a large number of assignment statements in the form:

rec1.col1 := rec2.cola;

Since there is a possibility of type conversion errors in some cases, I need to be able to trap errors and identify the offending column in the input table. The Oracle documentation suggests something like this:

step_num:= <n>
rec1.col1 := rec2.cola;
step_num:=<n+1>
rec1.col2 :=rec2.colb;

exception

	when <error type> dbms_output.put_line('error at '||step_num);
	raise;

Is there a better way for me to identify the location of the error?

Thanks,
Peter Schauss
