perl cgi database error handling

[dandelion]

Currently I am doing a perl-mysql project. and I used to program in java.
I have a question about database error handling.

In java, for each jdbc error we use catch , and in business layer write some meaningful message, then send this message to jsp page.

So how can I handle the DBI error nicely rather than just use die and throw a ugly database error message?

Thank you.

You can write your own error subroutine and call it rather than die.

Also search cpan, there should be several error handling modules that you might find useful.
