CAML: Difference between Field and Column
When defining a field in your feature, sometimes you want to do condition rendering, depending on what values are captured in certain fields. To retrieve them, you can use <Field Name="..."/> or <Column Name=".."/>
Field element returns formatted value, while Column element returns raw information. So for a field of type boolean, a Field element will return "Yes" / "No" while a Column element will return 1 / 0
