I don't know the book, so I could be barking up the wrong tree here but... I think you are confusing objects and primitive data types. An object of type Boolean has a property with a primitive type boolean. The type boolean can be either true or false. Each field/column in a row is returned as an Object (of the relevant type). In this case, your field is being returned as a Boolean object, with it's property set to either true or false. If your table has a column of some character type, then each row would be returned with individual Objects of type String. Does this make sense ? GTG
