How to find exact error column name

Question

hi all ,
My requirement is as follows .
I am trying to add a record into temp_emp table inside plsql block ,after executing it i am getting ORA-01438: value larger than specified precision allowed for this column error .I want to find for which column the error is coming .
In the below example i clearly know that deptno column precision is 2 and i am inserting bigger value that is why i am getting error .
let us consider a scenario where i am trying to insert 40 colunm values into table and one column is causing the problem , how to find that column alone .

Oracle does not provide the column information in the error message and I don't know of any way to do so outside of developing something convoluted. For example:
SQL> DECLARE
  2     te_row temp_emp%ROWTYPE;
  3  BEGIN
  4
  5     te_row.empno  := 1234;
  6     te_row.ename  := 'ABC';
  7     te_row.job    := 'CLERK';
  8     te_row.deptno := 1000;
  9
10     INSERT INTO temp_emp
11          VALUES te_row;
12  END;
13  /
DECLARE
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: number precision too large
ORA-06512: at line 8Also, that EXCEPTION block has a bug in it (no RAISE or RAISE_APPLICATION_ERROR).
