DB::Object::Fields::Unknown - Unknown Field Class

SYNOPSIS

    use DB::Object::Fields::Unknown;
    my $f = DB::Object::Fields::Unknown->new(
        table => 'some_table',
        error => 'Table some_table has no such field \"some_field\".',
    ) || die( DB::Object::Fields::Unknown->error, "\n" );

VERSION

    v0.1.0

DESCRIPTION

This class represents an unknown field. This happens when DB::Object::Fields cannot find a given field used in a SQL query. Instead of returning an error (undef), it returns this object, which is then ignored when he query is formulated.

A warning is issued by DB::Object::Fields when a field is unknown, so make sure to check your error output or your error log.
