Data::...Errors(3pm)

💅 Data::ObjectDriver::Errors — the vibes

okay bestie, so this is a page from User Contributed Perl Documentation, section 3pm, and the star of the show is the module Data::ObjectDriver::Errors. It's a whole container class for common database error codes. Container class, like a cute lil' box that holds your error constants. We love a tidy queen. 🎀

✨ NAME ✨

Data::ObjectDriver::Errors — container class for common database error codes, periodt. 💅

---

🦋 SYNOPSIS 🦋

eval { $driver->insert($obj); };
if ($@ && $driver->last_error() == Data::ObjectDriver::Errors->UNIQUE_CONSTRAINT) {
    ...
}

like, you wrap the risky insert in an eval, and then if $@ is truthy and $driver->last_error() equals Data::ObjectDriver::Errors->UNIQUE_CONSTRAINT, you know exactly what happened. iykyk. ✨

🌸 DESCRIPTION 🌸

Data::ObjectDriver::Errors is a container class for error codes that come out of DBI database operations. that's literally its whole job and it does it flawlessly. 👑

the way it works: database drivers can map the particular DBI errors of their particular database servers onto these constants, using their map_error_code methods. so your code doesn't have to care which database server was being dramatic — the driver translates, and you get the same tidy constant every time. 🫶

💖 DEFINED ERROR CODES 💖

• UNIQUE_CONSTRAINT — the application issued an insert or update that would violate the uniqueness constraint on a particular column. classic example: attempting to save a duplicate value to an indexed key field. no cap, the database said "not today" 💀

🌈 SEE ALSO 🌈

• "Data::ObjectDriver::Driver::DBD::map_error_code" — go read that one next, bestie, it's the whole mapping situation 💜
