Thanks, so basically, if I would want to use a Char field type, I would need to define it 208. When using Varchar(100), its maximum length is much greater than 100 then. Do you know what it is? Or, if I would wish to define it to a lower value, to support this, would there be a better field declaration than Varchar(100)?
