Answer / guru

The PRAGMA EXECPTION_INIT tells the complier to associate an
exception with an oracle error. To get an error message
of a specific oracle error.

e.g. PRAGMA EXCEPTION_INIT (exception name, oracle error
number)

Example

declare
salary number;
FOUND_NOTHING exception;
Pragma exception_init(FOUND_NOTHING ,100);
begin
select sal in to salaryfrom emp where ename ='ANURAG';
dbms_output.put_line(salary);
exception
WHEN FOUND_NOTHING THEN
dbms_output.put_line(SQLERRM);
end;
