# Data::ObjectDriver::Errors(3pm)

container class for common database error codes

## NAME

Data::ObjectDriver::Errors - container class for common database error codes

## SYNOPSIS

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

## DESCRIPTION

*Data::ObjectDriver::Errors* is a container class for error codes resulting from DBI database operations. Database drivers can map particular database servers' DBI errors to these constants with their `"map_error_code"` methods.

## DEFINED ERROR CODES

- •

  `"UNIQUE_CONSTRAINT"`

  The application issued an insert or update that would violate the uniqueness constraint on a particular column, such as attempting to save a duplicate value to an indexed key field.
