One of the things where data from databases and Delphi native types differ, is the support for NULL. When you work with databases a lot in Delphi, you want to have a datatype that supports NULL. In the past you had to use variants, but not any more! With the introduction of operator overloading, you can do this with record types, too. This session shows you how.
