@Matt Good point. Thanks for the tip.

@Guillaume I'm afraid I cannot help you with C.

Does anyone of you knows how to do the same in c.
You pass an error code and you get the message like perror in Unix.

Thanks

That should, of course, have ended with

ELSE
RAISE;
END IF;
END;

I think this article misses the real difference between SQLERRM and FORMAT_ERROR_STACK.

The latter returns the entire error stack (the clue is in the name). Sometimes the real error you want to identify is some way down the error stack - in which case SQLERRM is no good for you.

If looking for a particular error number in FORMAT_ERROR_STACK you can simply do a:

EXCEPTION
WHEN OTHERS THEN
IF INSTR(dbms_utility.format_error_stack, 'ORA-12345') != 0 THEN ...
ELSE
RAISE;
END;
