Unable to use a zero value KSUID with a sql driver/database #79

Open odannyc opened 10 months ago

odannyc commented 10 months ago

I'd like to pass all 0s to sql for querying, for example:

SELECT *
FROM users
WHERE id > '000000000000000000000000000';

This is not possible currently because this library treats a zero value ksuid as nil: https://github.com/segmentio/ksuid/blob/master/ksuid.go#L139-L144

func (i KSUID) Value() (driver.Value, error) {
    if i.IsNil() {
        return nil, nil
    }
    return i.String(), nil
}

Is there something I'm missing on how to pass 0s to sql or is it not possible? I'd like to avoid having to manage my own type which simply shadows the Value func if possible.
