Thanks for getting back.
What I meant was error handling in cases like when the database of the connection string does not exist.
Here's how I worked it out for some cases, when I already had tested the connection string:
Still, no error handling in this case. And if I do not test I'll get an error page if the connection string fails.
Not a very big deal, but a swallowing error handler could be useful for simple and quick pages from time to time, when there's really no other need for writing code.
