Hi all!

I have this problem where DBI (or CDBI) queries throw an exception and I'd like to show a meaningful error message to the user. I'm hoping for a module (have searched, no dice), or for advice writing one.

Let's say a unique constraint was violated during an insert in a SQLite database, and this exception was thrown: 

DBD::SQLite::st execute failed: column url is not unique(1) at dbdimp.
+c line 397 
[for Statement "INSERT INTO url (url, url_id) VALUES (?, ?)"

[download]

I'd like a portable (across databases) way to translate/decode this jibberish (from the user's POV) to something more database neutral, like a hash ref that I can render for the user: 

{
    dml => "insert",
    failure_reason => "unique",
    failure_details => "column url is not...",
    column => "url",
    value => "", #the value of url, from the code making the call
}

[download]

Or something like that.

So do you know of any modules that come close to this? Any other ideas?
