Since APEX 4.1 we've got the built-in feature of the Data Loader. This feature isn't widely used yet and that is a shame. In this session you will learn all the nifty features of this particular piece of APEX functionality. Afterwards you will be able to use it yourself, making your life a lot easier and your users a lot happier.

30. So “Insert New Value” only works with auto generated keys!
(it does insert a record with ST = NULL...)
So you have to manage that using triggers...
