If you are using TIBOQuery, you are working with a TDataset descendant. All the methods and properties of TDataset are available. Instantiate the Field Objects just as in the native VCL, by right-clicking on the iboquery to display the Fields Editor, then right-click on that display and select Add All Fields. You will notice that the Required property is present, along with all the others you are used to.
